The present invention provides a seal gasket which is inserted between the ball valve body and the seat retainer in the cryogenically cooled liquefied natural gas ball valve to prevent the leakage of fluid so that the seal gasket can be cured and contracted under the influence of cryogenic temperature to prevent the fluid from leaking. A seal gasket mechanism. Natural gas is transported through pi...
JST seals produce high-quality throttle valve and gate valve equipment seals. Choke packing throttle valve are control valves for production wells, which are used to control the flow of well fluid under production. The throttle valve also compresses the pressure from the reservoir and regulates the downstream pressure in the flow line. Choke packing is available in a variety of types and material ...
The seals made from carbon graphite materials have the common advantages of both metal and non-metallic materials. Its material characteristics includes excellent self lubrication, chemical stability, high thermal conductivity, high temperature resistance, corrosion resistance, high wear resistance, low expansion and easy maching. These characteristics of carbon graphite are necessary for pure wat...
The completion wellhead device refers to the oil (gas) tree, tubing head, casing head, and related accessories, which are used for suspension, support, control, regulation, and other oil (gas) equipment. In oil and gas extraction equipment, the sealing part plays a crucial role, and its performance is related to whether the oil and gas well can produce safely and efficiently. Sealing of commonly u...
The chemical name of polytetrafluoroethylene is PTFE (polytetrafluoroethylene). It has the highest chemical resistance and heat resistance, and can resist almost all aggressive substances. PTFE has low lubrication and high sliding speed. Wear resistance is usually low, and PTFE materials are prone to cold flow under pressure. JST Seals can produce PTFE fillers such as carbon fiber, graphite, bronz...
In the oil and gas field, seal will be exposed to high temperatures and pressure ranges means that standard polymer seals are unable to meet the customer requirements. JST seal materials including: Perfluoroelastomers (FFKM) Fluoroelastomers (FKM) HNBR Aflas PTFE PEEK UPE Elastomer and Polymer materials for the Oil and Gas industry Applications: 6A gate valve 6D ball valve Wellhead casing hanger o...
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: ...
PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing. Due to the inherent limitations of various elastomer grades, the application range of standard elastomer rotary shaft seals is l...
