Trunnion Mount Valves

Trunnion mount valves are a type of industrial valve used to control the flow of fluids, such as liquids, gases, and slurries, in high-pressure systems. The term "trunnion mount" refers to how the valve mounts on a trunnion, a cylindrical projection that serves as a pivot point for the valve.

The valve body is typically made of metal, such as cast iron, steel, or stainless steel, and may be lined with materials such as PTFE or rubber to improve corrosion resistance and reduce wear. The valve stem, the part of the valve that rotates to open and close the valve, is also usually made of high-strength metal.

One of the most common uses of trunnion mount valves is in oil and gas production and transportation. These valves are often used in pipelines to control the flow of crude oil, natural gas, and other hydrocarbons. They are also commonly used in chemical plants, power plants, and other industrial facilities to control the flow of fluids in high-pressure systems.

Due to the need for tight shutoff and precise flow control, trunnion mount valves are typically used in high-pressure systems operating at 600 psi or higher pressures. They are also designed to handle high-pressure differential applications and are operated manually, pneumatically, or electrically.

Habonim designs and manufactures high-pressure ball valves and valve automation packages specially built for safety, endurance, and reliability to cover gases and fluids control up to 1,000 bar (15,000psi). 

The Habonim valve series is for harsh conditions in oil & gas and petrochemical industries, for underground and above-ground installation. Its robust design can withstand heavy loads from large sizes, high pressures, and dynamic temperature cycles. 

The trunnion valve series is certified to API 6D (Habonim monogram #6D-1278) with a valve wall thickness that is in full compliance with ANSI B16.34. The trunnion valve line withstands the maximum differential pressure rating specified by the American National Standards Institute (ANSI). The product range offers a range of end connectors, providing design flexibility and customized to meet each customer's specific needs and preferences.

The Role of Metal Expansion Joints

Expansion joints, also known as bellows or compensators, are flexible connectors that are used in process and HVAC piping systems to absorb movements, such as thermal expansion and contraction, vibration, and misalignment. They are designed to prevent damage to the piping system, equipment, and surrounding structures by allowing for the movement and stress that occurs within the system.

There are several types of expansion joints, including metallic, non-metallic, and fabric. Metallic expansion joints are made of metal bellows and are typically used in high-pressure and high-temperature applications, as well as in applications that require a high degree of corrosion resistance. These expansion joints are typically made of stainless steel, but they can also be made of other metals such as Inconel, Monel, and Hastelloy.

The main function of metallic expansion joints is to provide flexibility in the piping system. They do this by allowing for movement in three main ways:

• Lateral movement: Metallic expansion joints can accommodate lateral movement, which is movement in a side-to-side direction. This is important in systems that are subjected to thermal expansion and contraction, as the pipes will expand and contract due to temperature changes.
• Angular movement: Metallic expansion joints can also accommodate angular movement, which is movement in a rotational direction. This is important in systems that are subjected to vibration, as the pipes will vibrate due to the flow of fluid or gas.
• Axial movement: Metallic expansion joints can also accommodate axial movement, which is movement in a back-and-forth direction. This is important in systems that are subjected to misalignment, as the pipes may not be perfectly aligned.
• In addition to providing flexibility, metallic expansion joints also help to reduce noise and vibration, and they can protect against the effects of corrosion, erosion, and abrasion. They are often used in a variety of industries, including power generation, petrochemical, pharmaceutical, and food and beverage.

Cryogenic Ball Valves

Cryogenic ball valves are a type of valve that is designed to function at extremely low temperatures, typically below -150°C. They are used in a variety of applications where low temperature fluids need to be controlled, such as in the storage, transport, and processing of cryogenic gases, such as liquid nitrogen, oxygen, and argon.

Cryogenic ball valves are equipped with special materials and features that enable them to operate effectively at such low temperatures. For example, the body of the valve may be made from materials such as stainless steel or aluminum that have low temperature properties, and the valve may be equipped with a special insulation material to prevent heat transfer from the environment to the valve. The ball and seat of the valve may also be made from materials such as tungsten carbide or ceramic that can withstand extreme cold and wear.

Cryogenic ball valves are used in a variety of industries, including chemical, petrochemical, oil and gas, and food processing. They are commonly found in cryogenic storage tanks, pipelines, and processing equipment. They are also used in research and development facilities, medical facilities, and other industrial settings where low temperature fluids need to be controlled.

Cryogenic ball valves are used in a variety of applications that involve the handling of materials at extremely low temperatures. Some common applications for cryogenic ball valves include:

• LNG (Liquefied Natural Gas) storage and transfer: Cryogenic ball valves are used to control the flow of LNG in storage tanks and transfer lines.
• Cryogenic tanks and vessels: Cryogenic ball valves are used to control the flow of cryogenic fluids in tanks and vessels used for storage and transportation.
• Refrigeration and air conditioning: Cryogenic ball valves are used in refrigeration and air conditioning systems to control the flow of refrigerants and other coolants.
• Industrial gases: Cryogenic ball valves are used in the production, storage, and distribution of industrial gases such as oxygen, nitrogen, and argon.
• Chemical and petrochemical processing: Cryogenic ball valves are used in the production and transportation of chemical and petrochemical products that require low temperatures for processing or storage.
• Aerospace and defense: Cryogenic ball valves are used in aerospace and defense applications to control the flow of cryogenic fluids in satellites, rockets, and other space vehicles.

Reotemp MSX HF Safety Pressure Gauge for Use in Hydrofluoric Acid Service

While corrosive acids have been used safely in industrial applications for many years, choosing appropriate pressure instrumentation for these sites necessitates specialized knowledge. Reotemp is aware of the consequences of acid leakage and developed the MSX HF Safety Gauge. 

The REOTEMP Model MSX HF Safety Gauge is a mechanical pressure gauge designed for hydrofluoric acid operation. The diaphragm seal components and the pressure gauge internals are Monel A400, per EPA dual containment regulations. The entire diaphragm seal system is welded and coated with acid-detecting paint, which provides a visible signal in the case of a process leak around the diaphragm seal.
