A spring energized seal is a type of dynamic seal that uses a spring to provide a constant force against the sealing surface. The spring is typically made of stainless steel, alloys sometimes even PTFE and PEEK, and it is compressed between two components, such as a gland and shaft. As the components move relative to each other, the spring compresses and deforms, creating a dynamic seal that preve...
Grooves and Glands The physical space occupied by the seal is usually referred to as a groove, but it can also be referred to as a gland. In most cases, it’s a rectangular groove cut into the hardware whether it be on a piston, in the housing for a rod, or in the face of two mating surfaces. Compared to O Ring and elastomer seals, PTFE and polymer seals are critically dependent on hardware conditi...
Spring energized seal is a spring-actuated, pressure-assisted sealing device consisting of a PTFE (or other polymer) jacket partially encapsulates a corrosion-resistant metal spring energizer. When the JST seal is installed in the gland, the spring is under compression, forcing the jacket lips against the gland walls and there by creating a leak-tight seal. The spring provides permanent resilience...
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...
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...
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...
JST’s FS Casing and Tubing Hanger Seal use high performance elastomer seal technology for arduous duties where there are large clearances between mating parts of wellhead and associated assemblies. The FS Seal design supports reduction in installation time, correct placement in the housing and simple installation. FS seals have been validated in accordance with API requirements for using on surfac...
In the field of industrial sealing, T Seal is gradually attracting widespread attention for its unique design and excellent performance. T seal is combined with 1 piece of elastomeric ring and two pieces of anti-extrusion rings. The elastomeric ring is one of the core components of T Seal. This elastic material has excellent flexibility and resilience, and can be tightly fitted to the piston/rod, ...
