JST S seal is elastic sealing element composed of a high modulus elastomer and two integrated anti-extrusion springs which allows the seal to withstand large compression gaps. The S seal can be customized designed based on temperature, medium, and environment. Sealing materials utilized for wellheads which need to withstand pressures as high as 15 000 psi, and temperature from –29°C to +177°C (–20...
JST designs and manufactures spring energized lip seals for ball valve. In this article, we will introduce some lip seals used for different sealing application in ball valve. Lip seal type FVR is used for ball valve seat sealing. As shown in picture Fig-1, the FVR lip seal contains four parts. 1- T ring (material: carbon filled PTFE), 2- U ring (material: carbon filled PTFE), 3-Spring (material: ...
Viton ® It is a synthetic high-performance fluoropolymer elastomer (rubber) commonly used for strict application of O-ring. According to the classification of FKM according to ASTM D1418 and ISO 1629 (hence, they are also referred to as "FKM o-rings"), fluororubber o-rings are preferred because they have high resistance to extreme high temperatures and harsh atmospheric conditions, as well as ...
6D spring energized seals outperform other sealing technologies in terms of longevity and reliability in several key ways: Extreme Operating Conditions: 6D spring energized seals are designed to withstand extreme operating conditions, including high pressure, high temperature, and aggressive chemical environments. Their ability to maintain a secure seal under these conditions contributes to their ...
JST’s metal end cap seal is a customized elastomer-to-metal seal that combines the advantages of metal-on-metal components with the flexibility of elastomeric seals for maximum extrusion resistance in high-pressure wellhead sealing environments. These high performance elastomer-to-metal bonded sealing elements provide the high level of extrusion resistance necessary for high pressure casing and tu...
Choosing the right seal for your application is not easy. If you want a reliable and long-lasting performance, it’s crucial to consider the following operational conditions. Working Pressure: High pressure applications require higher durometer seals to resist extrusion. Working Temperature: Different elastomers have different low and high temperature capabilities. Installation Parameters...
Oil well production is the most important stage in the lifespan of oil wells, which prepares oil or natural gas for final treatment by releasing hydrocarbons. Separation is usually carried out on the seabed, rather than on the platform of offshore oil wells. In addition to dealing with system pressures up to 1,380 bar (20,000 PSI) and temperatures exceeding 900C(1,650F) in flare stack controls, se...
We are thrilled to introduce the new HNBR packer element which is made of HNBR 85 Shore A, and this rubber material is especially developed for packer element. The HNBR element passed customer’s test. The HNBR Rubber Packer Element is designed for downhole completions, where it serves as a critical component in isolating different zones within the wellbore. It is engineered using high-quality hydr...
PE001 is a carbon-filled PTFE material (Black color), it has better high and low temperature resistance,excellent creep performance, can withstand high pressure for a long time, and is more resistant to extrusion, excellent properties in chemical resistance, wear resistance and wide-range operation temperature. It is usually used as composite seals with energizer, making i...
