Dual-Seal Trunnion Mounted Ball Valves Offer Twice the Life for Pipeline, Petrochemical, and Process Industries

WOM Trunnion Mounted Ball Valves
WOM trunnion mounted ball valves in service.
WOM (Worldwide Oilfield Machine) manufactures a dual seal ball valve is the only trunnion mounted ball valve with two independent seats on both sides of the ball. The primary seat takes the normal wear and tear when the valve is cycled. If it ever gets damaged the secondary seat takes over. This redundant sealing technology can more than double the useful life of the valve.

two independent seats
The only trunnion mounted
ball valve with two independent seats.
Even after the primary seat gets damaged, it will continue to work as a wiper ring. Each time the valve is cycled the primary seat will clean trash and line debris off of the ball before it can damage
the secondary seat.

WOM’s Dual Seal Ball Valve typically comes with two seats upstream and two seats downstream of the ball. But it can be configured to have the outer seat on the downstream side modified to act as a Third seal. The third seal will provide one more seal on the downstream side of the valve. The valve is still bi-direction, even with the third seal option.

WOM Ball ValveThe Dual-Seal was designed specifically so that it could not trap pressure in the body cavity. This is critical in hazardous liquids service, where thermal expansion can cause pressure build-up inside the body. The Dual -Seal will automatically self-relieve to the low pressure side of the valve. However, if the third seal is installed, it forces the valve to self-relieve to the upstream side. You are in control of the direction that the self-relieving seats vent to.

Redundant sealing technology, the third seal, and being able to control the direction of the thermal expansion pressure makes the Dual-Seal ball valve unsurpassed in real life performance. This combination of seats gives you a valve that will outlast typical ball or gate valves. It will lower your operational costs, add safety, and increase reliability.

Accurate Dosing of Corrosion Inhibitors Greatly Improves Corrosion Prevention and Extends Pipeline Life

Pipe Corrosion
Accurate dosing of corrosion inhibitors in industrial applications, especially in the chemical, process and oil and gas industry can be a real challenge. These industries cope with demanding environmental and process conditions in production and operation. In oil and gas, it is common that wells produce other products that are likely to cause corrosion, such as water and carbon dioxide. Pipelines are required to transport oil and gas products from the well, sometimes over long distances. Even though they are designed to last for decades, corrosion processes are responsible for degradation and significant losses. It is clear that the best way to combat corrosion economically is through prevention using chemical inhibitors.

A corrosion inhibitor system will add small concentrations of (bio)chemicals into the process which form a film on the interior surface of the pipe or vessel, preventing corrosive attack. The effectiveness of an inhibitor system greatly depends on the correct injection amount, and can be influenced by the environmental and process conditions; so accuracy is crucial here. A properly applied chemical corrosion inhibitor system is very effective in lowering corrosion rates, with the potential to reduce corrosion rates up to 99%.

The key in determining the overall rate of corrosion over the life of a pipeline is determined by the proportion of time for which the corrosion inhibitor is available, and the correct concentration. In order to accurately assess the availability of corrosion inhibitor, it is necessary to have some means of accurately measuring the dosage of inhibitor being injected.

CORI-FLOWUsing a low flow control system containing a mass flow controller (MFC) allows for very accurate corrosion inhibitor dosing. High accuracy and high turndown ratio is achieved based on pure mass flow measurement with this type of flow meter. A device such as the Bronkhorst (mini) CORI-FLOW mass flow controller can directly control valves and pumps via it's on-board PID controller, and be further optimized with ancillary PLC and HMI controls, extending both performance and flexibility.

The application of chemical corrosion inhibitors can significantly reduce the rate of corrosion  and using a dosing system with an integrated MFC (such as the Bronkhorst (mini) CORI-FLOW) enables real-time monitoring, control and logging of injection rates. This allows online checking of flow rates and instantaneous re-setting of the required flow rate. Asset management and preventive maintenance is supported with several active diagnostics.

Patented Pressure Gauge Technology Eliminates Need for Liquid Fills

Pulsating gauge
Pulsations caused by compressors and other machinery.
Patented technology by Ashcroft dampen pulsations
without the cost and hassle of liquid-fill.
Compressors pumps and other machinery create pulsation and vibration that can make your pointer unreadable.  Liquid-filled gauges can solve your problem, but they command a higher price.  So to keep costs down, you have to stock both dry and liquid-fill gauges.

In response, Ashcroft developed their patented PLUS!™ Performance technology. Gauges with PLUS!™ Performance employ a unique cartridge that surrounds the pinion with an engineered dampening medium. This viscous compound encapsulates and stabilizes the pinion in order to restrict the overactive pointer motion due to vibration. A throttle screw helps to neutralize pulsation by restricting the flow rate of the pressure medium into the Bourdon tube.


Plus! technology
Pinion is stabilized by a cartridge with viscous compound.
While a standard dry gauge may become indecipherable, both liquid-filled and PLUS!™ Performance gauges continue to provide stable readings.  the liquid fill can leak, be affected by extreme ambient temperatures, and become an environmental hazard when disposed of. Ashcroft's patented PLUS!™ Performance option assures fast and easy readings so you can focus on what matters and standardizing with PLUS!™ Performance helps consolidate your SKUs, and less inventory means lower costs.

The Valtek® Mark Eight™ Y-Pattern Control Valve

Mark Eight Control Valve
The Valtek Mark Eight Control Valve Features
(Click for larger view)
The Valtek® Mark Eight™ control valve is designed with a unique “Y” style globe body that provides higher flow capacities and less process turbulence than conventional globe valves.

Because of its nearly straight-through flow passage, the “Y” style body is less flow restrictive than a normal globe-style body. This permits less pressure to be converted into velocity as the fluid passes through the seat, resulting in a lower valve recovery factor and higher capacity.

Mark Eight’s straight-through design generates less valve and piping turbulence which significantly reduces harmful noise and vibration levels.

Applying Gas Pipeline Block Station Valves


A block valve is used on gas transmission systems to isolate a segment of the main gas pipeline for inspection and maintenance, or for shutdown in the case of a natural disaster or pipeline damage.

The block valve is typically a full-bore, soft seated ball valve to allow for scraping. However, this type of valve cannot be opened against full differential pressure without damage to the valve seats. Therefore, a bypass system is installed around the block valve, and used to balance the pipeline pressure prior to opening. Plug valves should be used in the bypass as they are capable of opening and throttling against full differential pressure without damage.

The Requirement of a Bypass

Let's see what would happen if the block valve, which is a soft seated ball valve, was operated against full differential pressure. As it is initially opened the huge pressure drop across the valve generates high velocity flow carrying fine dust, rust, or scale particles in close proximity of the valve seats. This results in seat damage and a block valve that cannot seal bubble tight once closed.

The Bypass Valve Sequence

To avoid this, a bypass system is utilized to balance the pressure either side of the block valve prior to opening it. With the vent valve closed, bypass valve 1 is opened allowing pressure into the bypass. In this case, a plug valve should be used, as it can be opened against full differential pressure without seat damage. Now bypass valve 2 is slowly opened, gradually building pressure in the downstream section until the pressure either side of the block valve is equalized. A plug valve is also used here capable of throttling the flow without seat damaged. With the pressure now equalized the block valve can be opened safely without the risk of seat damage. The two bypass valves have now done their job and can be closed providing bubble tight shutoff against the main pipeline.

Venting a Pipeline Section

Block stations are also used to vent sections of the pipeline into the atmosphere. This operation would start with all valves in the closed position. Bypass valve 1 is then opened allowing pressure into the bypass station. The vent valve is now slowly opened to release the pipeline pressure. Once again, this is a demanding application opening against full differential pressure, hence a plug valve is used to ensure bubble tight isolation to the atmosphere once closed.

Guided Wave Radar Transmitters: Accurate and Reliable Level Measurement for the Widest Choice of Installation Options and Applications

guided wave radar level

Guided wave radar transmitters are widely used across different industries. These devices with their simple installation and trouble-free operations help industrial companies save time and money. They are ideal for a large number of process applications ranging from simple to complex.

How Do Guided Wave Radar Transmitters Work?


Guided wave radar transmitters rely on microwave pulses. Since microwaves are not affected by dust, pressure, temperature variations, and viscosity, this type of transmitter produces highly accurate results. 

A low-energy microwave pulse is sent down a probe, and a part of it is reflected back when the pulse hits the process media. The liquid level is directly proportional to the time-domain reflectometry. The time when the pulse is launched and received back is measured to determine the distance from the surface of the media. 

Types of Guided Wave Radar Level Transmitters


Guided wave radar level transmitters are available in different probe configurations. Selecting the right probe is important for successful implementation of the device. While manufacturers offer a range of guided wave radars, most are derived from the three basic probe configurations: single element, twin element, and coaxial.

Single element probe — The single element probe is the most widely used and least efficient device. The device is popular since it is more resistant to the coating of the liquid. 

Twin element probe — The twin element probe is a good, general purpose probe that is generally used in long-range applications. They are ideal in situations where flexible probes are important for successful reading. 

Coaxial probe — The coaxial probe configuration is the most efficient guided wave radar level transmitters. The probes are used in more challenging low-dielectric applications. 

Benefits of Guided Wave Radar Level Transmitters


Dielectric Constant and Reflectivity - Guided WaveRadar (GWR)
(Courtesy of Schneider Electric Foxboro)
Guided wave radar level transmitters provide a range of benefits in different applications. The concentration of the measuring signal is strong and clean. This is due to the narrow path of the signal propagation that reduces the chances of impact by stray signals due to obstacles or construction elements inside the tank. 

Another benefit of guided wave radar level transmitters is that they are easy to install. No mounting holes are required to install the device. This results in cost savings for the organization. The waveguide can be formed to follow the tank’s contours or mounted at an angle. 

The device is ideal in situations where an interface measurement is required. The measuring signals can penetrate the medium deeply, resulting in more accurate results. The waveguide technology is suitable for applications where the medium is subjected to heavy vapors, foam, and dust. 

Guided wave instruments can detect changes in dielectric consents on the boundary of a property. The device can be configured to detect level at both the top and the bottom of a layer of emulsion. 

Industrial Application of Guided Wave Radar


Guided wave radar level transmitters are increasingly being used in process industries. The sensors are used in situations that previously employed ultrasonic, hydrostatics, and capacitance. The accuracy specification of the basic model range is up to ±5mm, while the accuracy of the advanced models is up to ±2mm. 

The device is generally used in industries to take level readings. The readings are used for local indication and visualization in control systems. 

Moreover, guided wave radar level transmitters are also used for managing liquid inventory, determining safety limits, dry run protection, and leak detection. Other applications of guided wave radar level transmitters include communicating low limits to suppliers, automated ordering systems, and streamlining the logistics process. 

Guided radar level measurement is also suitable for bulk solids. The surface type is not restricted to liquids since the reflected waves are guided easily through any medium. Foam formation and turbulent liquid surfaces and different angled surfaces (as is the case with bulk solids) don’t influence the accuracy of the reading.

Selection of Guided Wave Radar Level Transmitters


Selection of guided wave radar level transmitters should be based on the requirements of the task. Generally, the rigid single element probe configuration is ideal for angled installations for flowing liquids. The dual flexible wire probe is suitable for most other common applications. 

A coaxial probe configuration is recommended for liquids that are cleaner with low dielectric constant and with turbulence on the product’s surface. This type of guided wave radar device is also recommended for installations where the probe is near the tank wall or other obstacles. 

Make sure that the device can withstand the range of temperature within the tank. Most GWR devices are rated up to 850 deg F or 450 deg C. You should select a device with added signal strength since this will result in increased reliability and accuracy of the devices. 

Guided wave radar level transmitter with dynamic vapor compensation is recommended where a high level of accuracy is required under a high-pressure environment. The measurement taken from the device can compensate for changes in vapor dielectric, which results in improved accuracy. 

Other factors that should be considered include mounting and proximity. Single probe configuration can be installed almost anywhere. But the single probe configuration can only to apply to specific situations. 

Lastly, the probe length of the device should be of the right length. The length should be according to the measurement rate. This is an important consideration as it can help in ensuring accurate reading with minimum chances of an error. 

Guided wave radar level transmitters can also be used with an agitator. However, certain things must be considered prior to use the device. The probe must be prevented from contacting the agitator blades. Make sure that you confirm the ability of the probe to withstand the force inside the medium. This is important since turbulent on the surface may decrease the accuracy of the measurement. You can install the device in a bypass chamber or stilling well for an agitated tank.

Hazardous Area Classifications in the USA

Hazardous Area Classifications
Understanding Hazardous Area classifications is critical.
An important aspect of safe installation is to determine the hazardous area classification in the area. Checking the area classification is also important for safe electrical wiring. The hazardous area classification should be known by personnel before starting work in an area.

Hazardous areas refer to locations with a possible risk of explosion or fire due to dangerous atmosphere. The hazards can be associated with flammable vapors or gases, ignitable fibers, and combustible dusts.

Different hazardous area classifications exist in the North America and Europe. Generally, the National Electric Code (NEC) classifications govern hazardous areas in the US. While in Europe, hazardous area classification has been specified by the International Electrotechnical Commission (IEC).

CLASS
NATURE OF HAZARDOUS MATERIAL
CLASS I
Hazardous area due the presence of flammable vapors or gases in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include natural gas and liquified petroleum.
CLASS II
Hazardous area due the presence of conductive or combustible dusts in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include aluminum and magnesium powders.
CLASS III
Hazardous area due the presence of flammable fibers or other flying debris that collect around lighting fixtures, machinery, and other areas in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include sawdust and flyings



Division groups hazardous areas based on the chances of an explosion due to the presence of flammable materials in the area.

DIVISION
LIKELIHOOD OF HAZARDOUS MATERIAL
DIVISION 1
Areas where there is a high chance of an explosion due to hazardous material that is present periodically, intermittently, or continuously under normal operation.
DIVISION 2
Areas where there is a low chance of an explosion under normal operation.


Group categorizes areas based on the type of flammable or ignitable materials in the environment. As per NEC guidelines, Groups A to D classify gasses while Groups E to G classify dust and flying debris.
GROUP
TYPE OF HAZARDOUS MATERIAL IN THE AREA
GROUP A
Acetylene.
GROUP B

  • Minimum Ignition Current (MIC) value equal to or less than 0.40
  • Maximum Experimental Safe Gap (MESG) value equal to or less than 0.45 mm
  • Combustible gas with more than 30 percent volume
Examples include hydrogen, ethylene oxide, acrolein, propylene oxide.

GROUP C
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value between 0.40 and 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include carbon monoxide, hydrogen sulphide, ether, cyclopropane, morphline, acetaldehyde, isoprene, and ethylene.

GROUP D
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value greater than 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include ammonia, gasoline, butane, benzene, hexane, ethanol, methane, methanol, natural gas, propane, naphtha, and vinyl chloride.

GROUP E
Area contains metal dusts such as magnesium, aluminum, chromium, bronze, titanium, zinc, and other combustible dusts whose abrasiveness, size, and conductivity present a hazard.

GROUP F
Area contains carbonaceous dusts such as charcoal, coal black, carbon black, coke dusts and others that present an explosion hazard.
GROUP G
Area contains combustible dusts not classified in Groups E and F.
Examples include starch, grain, flour, wood, plastic, sugar, and chemicals.

Wireless Networking in Industrial Plants

Wireless Networking in Industrial Plants
Wireless networking serves as the ideal alternative to high-cost industrial wiring. The setup also provides superior performance, solving the problem of electrical surges that result from field wiring.

Using a wireless system can result in an efficient supply of networking resources to field devices. The system facilitates an effective exchange of data between the host server and the field devices in the industrial setting.

Only a few industry-grade wireless field sensors have been offered so far in the year 2019. The reason for this is mainly a lack of information regarding its benefits. Once the cost-saving aspects of wireless networking become known in the industrial setting, it will likely spur the demand in the market and lead to an influx of innovative wireless devices for different field applications.

Benefits of Wireless Networking Systems in the Industrial Setting Explored 

Wireless technologies offer great value over wired solutions. A reduction in cost is just one of the many benefits of switching to the wireless networking system. There are many benefits, including enhanced management of legacy systems that were previously not possible with a wired networking connection.

Here is an overview of some of the value-added benefits of adopting wireless networking in industrial plants.

Reduced Installation Costs 

Savings in installation costs is the key benefit of a wireless networking system. The cost of installing a wireless solution is significantly lower as compared to its wired counterpart.

Installing a wireless network requires less planning. Extensive surveys are not required to route the wires to control rooms. This reduced installation cost is the main reason industrial setups should consider going wireless instead of having a wired networking system.

Improved Information Accuracy 

Adopting wireless networking also results in improved accuracy of information. The wireless system is not prone to interferences. As a result, the system ensures consistent and timely transfer of information from one node to another.

Enhanced Flexibility 

Enhanced flexibility is another reason for deploying wireless networking solutions in an industrial setting. Additional points can be awarded easily in an incremental manner. The wireless system can also integrate with legacy systems without any issues.

Operational Efficiencies

Migrating to wireless networking can help in improving operational efficiencies as well. Plant managers can troubleshoot and diagnose issues more easily. The system facilitates predictive maintenance by allowing the monitoring of remote assets.

Human Safety 

Another critical factor that should influence the decision to migrate to wireless networking is the human safety factor. Wireless technologies allow safer operations, reducing exposure to harmful environments. For instance, a wireless system can be used in taking a reading and adjusting valves without having to go to the problematic area to take measurements.

Efficient Information Transfer

Another advantage is that the time required to reach a device is reduced. This results in a more efficient transfer of information between network segments that are geographically separated. The industry wireless networking standards use IP addresses to allow remote access to data from field devices.

With wireless networking systems, readings can be taken more frequently that can help in early detection and reduction of possible incidents.

Wireless Networking Standards for Industrial Plants

The ISO100 standards committee has introduced a whole set of new standards for wireless communication in industries. The first standards include the ISA100.11 that pertains to processing data transfer while fulfilling limited control needs in the industries.

Wireless Networking in Industrial Plants

with ultra-efficient BLE Instrument Area Networks.

ANSI and ISA have adopted the ISA100.11a standards for wireless communication in process industries. However, the standard has yet to pass through the international IEC standardization. This is due to the fact that ISA100.11a and IEC’s WirelessHART standards address the same market.

Technical Basis 

ISA100.11a is based on IEEE 802.15.4:2006 standard, similar to WirelessHART with 15 to 16 channels in the ISM band 2.4GHz range. However, the former can be used for a wider networking application in the industrial sector such as peer-to-peer messaging and network segmentation.

Distinct Hopping Patterns

Each segment in the network may use a distinct hopping pattern, unlike the WirelessHART. Moreover, the network segment has a dedicated time slot that results in the formation of large networks with overlapping segments.

Mesh Networking 

Another important point to note is that the ISA1001.11a wireless networking standard for industrial process makes use of mesh networking, which is similar to WirelessHART. However, the standard also allows devices at the network’s edge to not route information to different devices. This results in increased security that prevents unauthorized access to networks.

While not being technically different, the details of the two standards set them apart. However, the IS100.12 is already in development, and it will reduce the divergence in specifications between WirelessHART and ISA100.11a.

Challenges in Adopting Industrial Wireless Networking

Industrial wireless communication technology is a work in progress. A lot of work is required to address specific technical challenges for adopting the networking solution. Some of the challenges include evaluation and communication of the wireless technologies that are available for industrial concerns.

Another challenge in the adoption of wireless technology is solving the issues of latency or time synchronization. This is important to ensure the reliability of data transferred in the industrial setting.

Based on the challenges identified, here are three key suggestions for implementing wireless technology in the industrial setting.

  • Create a science-based methodology for measuring the performance of wireless communication
  • Create guidelines for the deployment of wireless networking in an industrial environment
  • Address issues of latency in systems with high-reliability aspects with error rates less than 10 percent

Key Takeaway

Wireless networking is an enabling technology that can result in improved operational efficiency in the industrial systems. The technology can improve control and safety and lead to enhanced cost savings.

Adoption of the wireless networking system creates huge potential for increased operational efficiencies. The system can reduce installation cost, enable enhanced monitoring, reduce risks, and improve profitability.

Types of Electrical Connectors Used for Hamilton Process Analytics Sensors

VP – This is a common connector used throughout the Hamilton sensor product line. VP is abbreviation for “VarioPin”. The VP designation often includes a number referring to the number of exposed poles on connector head. Example VP6 = 6 pole.





K8 connectors are typically used on pH / ORP sensors which lack temperature compensation. These connectors have a two pole design comprised of the center core and outer metallic threaded connection.




S7 & S8 – S7 and S8 connectors are typically found on sensors which no temperature compensation. They are the same basic design however S8 connectors have PG13.5 mounting threads, while S7 connectors do not. These connectors are recessed thus care must be taken to avoid moisture getting trapped which could lead to a short circuit.




M12 - Metallic threaded M12 connectors are found on Dissolved Oxygen Sensors and Cell Density products. M12 adapters have either 4 or 8 poles hidden within the socket. Since the poles are recessed avoid getting moisture inside the connection.





T82 – The T82 connector is sometimes known as a D4 connector. It uses a twist lock design to secure the cable to the sensor. These connectors are less common.





Memosens – These inductive electrical connectors are only found on digital pH sensors using Memosens technology. They use a twist lock design to affix the cable. There are no exposed metallic
connections on Memosens connectors.

Understanding Cavitation in Valves

Download the Flowserve Cavitation document here.

According to Wikipedia, "Cavitation is the formation of vapor cavities in a liquid, small liquid-free zones ("bubbles" or "voids"), that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities in the liquid where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave."

Cavitation presents serious concerns to engineers and specifiers of  control valves. Understanding ways to mitigate cavitation is important. Flowserve has put together this excellent document on understanding cavitation and offers solutions on reducing or eliminating its effects.
