Hammer union seal application

 A hammer union seal used in hammer unions, some customer also called it weco seals which are widely used in the oil and gas industry for connecting pipes or valves together temporarily. These unions are designed to provide a quick and reliable connection that can withstand high pressure and harsh conditions commonly found in drilling operations.


The seal in a hammer union typically consists of a combination of materials, such as NBR or HNBR and sometimes metal rings like stainless steel or brass. When the two halves of the union are hammered together, the seal is compressed between the male and female parts, creating a tight and secure connection. This seal prevents leakage of fluids or gases under high pressure.


JST factory developed different material to suit for hostile working condition such as H2S, CO2, CH4.


Hammer union seals or pressure manifold seals are key components in ensuring safety of piping systems in oil and gas operations. They need to be durable, resistant to corrosion, and capable of maintaining a reliable seal even in challenging environments. Regular inspection and maintenance of these seals are essential to prevent leaks and ensure the continued efficiency of the piping system.

What is the difference and advantage between rubber seal and metal seal?

Rubber seals   and   metal seals   are two common types of sealing components used in various applications across industries. Each type of seal has its own advantages and differences that make them suitable for different purposes. Let’s explore the differences and advantages of rubber seals and metal seals: Rubber Seals: Advantages: Flexibility: Rubber seals are flexible and can conform to irregular surfaces, making them effective in sealing applications where there may be slight imperfections or movement between mating surfaces. Sealing Properties: Rubber seals offer excellent sealing properties, providing effective barriers against liquids, gases, dust, and other contaminants. They can create a tight seal to prevent leakage and maintain the integrity of the enclosed environment. Vibration Dampening: Rubber seals have inherent vibration dampening properties, making them suitable for applications where shock absorption or noise reduction is required. Differences: Material...

Choosing the Right Spring and Seal Jacket Materials for High-Temperature and Corrosive Fluid Applications

  Spring energized seals   have been widely used in harsh working conditions such as extreme operating temperatures, high pressure, corrosive chemical media, low friction, and high operating speeds. The main materials for seal Jackets aremodified PTFE and other high-performance plastics. PTFE is a sealing material with superior chemical resistance and good heat resistance compared to perfluorinated rubber. It can be applied to the vast majority of chemical fluid solvents,  hydraulic oils, and lubricants. Its compression set is very small, so it can provide long-term sealing performance. Spring energized seals use various special springs to overcome the elastic problems of PTFE or other high-performance Plastics. JST has developed sealing components that can replace the vast majority of applications in static  or dynamic (reciprocating or rotating). The temperature range can be from -196℃to 300℃,  the pressure can range from vacuum to ultra-high pressure of ...

What are the groove types of spring energized seals?

图片
  Open groove The open groove structure is the most recommended groove form. The open groove structure is a separate two-piece design. The  lip seal  does not need to be stretched or twisted for assembly.(Fig:4-1) Typical features: The lip seal does not need to be stretched or twisted for assembly. Lip seal can be disassembled and assembled repeatedly without causing damage to it. Two-piece structure groove type may increase manufacturing costs. Stepped groove The stepped groove is a one-piece step design. The step is to keep the sealing ring in the groove. The height of the step is very small and no installation tools are required. The lip seal can be easily pushed into the groove. For  piston sealing , Stepped groove is a good structure. Stepped grooves are not a good choice when there is back pressure. (Fig 4-2) Closed groove The closed groove is a one-piece integral design and is not recommended. It is only suitable for certain seal diameters, which requires stre...
