The Ring Type Joint was originally developed for high pressure/temperature applications in the petroleum industry, mainly used for drilling and completion equipment in oil fields. However, today, this product series can also be used for valves and pipework assemblies, as well as some high integrity pressure vessel joints. There are three types of ring type joint gasket designs, the R type, RX type...
Hammer Union Seals (Weco Seal) are used in hammer union-style pipe connections to establish flow lines and prevent leakage. They are used in the Oil & Gas Industry, in steel mills, chemical plants, strip mining, and marine dredging. JST Hammer Union Seals are available in a range of configurations and materials to match the specific performance requirements of your demanding operating env...
Packer elements are components used in oil and gas well completion operations to isolate different zones of the wellbore. The design factors of packer elements include: Material Selection: The choice of material for the packer element is critical to its design. It needs to be able to withstand the downhole conditions, such as high temperatures, pressures, and corrosive fluids. Common materials use...
Packer Elements are elastomeric components designed to be used between sections of oil and gas production tubing, providing superior sealing and isolation capabilities. Made of high-quality rubber material such as NBR, HNBR and Aflas, the packer element provides superior sealing performance, ensuring maximum well integrity and efficient production. Designed for challenging downhole environments, P...
OD (Outer Diameter) face seals are used on the FLS and FLS-R seat. They are a type of mechanical face seal that's used in conjunction with the ID (Inner Diameter) face seal to provide a seal between the seat and the seat pocket of FLS style valves. FLS ID and OD face seals are used in all sizes of valves ranging from 1-13/16” to 7-1/16”. The OD seal you’ll receive is spring-loaded and pressure-ene...
TFM is a modified PTFE (polytetrafluoroethylene), commonly known as white polytetrafluoroethylene. This material has excellent chemical properties and is the lowest friction coefficient among all solid materials. The wide temperature range (-200 ℃ to+260 ℃) and mechanical properties makes it a widely used universal material. TFM Modified PTFE has the same excellent chemical resistance and thermal ...
Finite element analysis (FEA) is a computer-based technique used to calculate the performance of components in practical applications. This advanced technology can determine how components are affected by extreme temperatures and pressures, specific stresses, and aggressive chemical environments. Proficient use of FEA simulations enables accurate modeling by predicting behavior, eliminating the ne...
Explosive decompression mainly occurs on materials that seal gas media, which is produced when the high-pressure gas drops to a very low pressure level in a very short time. This type of pressure reduction usually leads to damage to the seals. Elastomer materials may be torn at multiple locations or form bubbles on the surface. Explosive Decompression Testing JST is a leading manufacturer and deve...
Sour gases containing hydrogen sulfide/sulfide (H2S) can have a very adverse effect on elastomers. The elasticity that is not resistant to corrosion becomes hard and brittle, losing elasticity and sealing ability, ultimately leading to sealing failure. JST has developed various sour gas resistant elastomer materials for the oil, natural gas, and petrochemical processing industries with the third-p...
