The environments in the oil and gas industry are extremely harsh. High pressures, temperatures, and corrosive substances pose significant challenges to equipment reliability. Seals are essential to prevent the leakage of oil, gas, and other fluids, ensuring safe and efficient operations. A seal stack is a combination of multiple sealing elements designed to provide a reliable barrier. It cons...
SPGW hydraulic seals are designed for heavy-duty applications, often used in hydraulic cylinders, offering a combination of wear resistance, low friction, and durability. Here are some key features of SPGW hydraulic seals: 1. Material: Bronze-filled PTFE (Polytetrafluoroethylene): Provides excellent resistance to wear, extrusion, and deformation. NBR/Nylon: Often combined with PTFE, these provide ...
Sealing at cryogenic temperatures has its own unique set of challenges. To provide superior protection against leakage in cryogenic valves for LNG, cryogenic seals should be designed with the following properties in mind: Jacket material that tolerates thermal cycling A spring energizer to compensate for shrinkage Anti-extrusion lip geometry JST has a wide range of solutions for cryogenic sealing ...
In the oil and gas industry, the risk and consequences of unplanned downtime are greatest in extreme environments. JST understands the demands you face every day and offers a range of fully tested and certified wellhead sealing products to reliably meet your business and technical challenges. You can trust our FS seals and S seals as well as our T seals and locked T seals to perform in the most ch...
Backup rings play a vital role in preserving the integrity of seals within pressurized aerospace hydraulic systems, minimizing leakage, and extending the lifespan of the components they protect. What are Backup Rings? The back up ring material could be PEEK, modified PTFE. PEEK™ back-up rings are designed to prevent extrusion in elastomer O-ring sealing systems. These rings are designed to close o...
Application of FFKM in O-Rings, seals and gaskets can meet the chemical resistance and high temperature requirements of strictly regulated industries. Equipment operators in critical and strictly regulated industries such as oil and gas, chemical refining and processing, aerospace, pharmaceutical and food processing, and semiconductor chip manufacturing all face a common pain point: How can the el...
JST makes custom and standard PEEK back-up rings. The PEEK back-up ring is made of polyetheretherketone (PEEK) material. PEEK is a high-performance thermoplastic with exceptional properties. It has high temperature resistance, capable of withstanding extreme temperatures without significant degradation. It also exhibits excellent mechanical strength, providing durability and reliability. PEEK is c...
What is the key to JST’s success in continually bringing innovative, groundbreaking solutions to the market? Selecting the right materials with a consistent approach is one of the most crucial steps. Developing high-performance elastomeric and plastic components that outperform and outlast expectations in the world’s harshest industrial conditions is not easy. There are many factors to consider: e...
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 sur...
When designing a cryogenic seal, the first step is to determine the operating temperature range of the seal. Typically, cryogenic seals operate below -65 degrees Fahrenheit. When designing seals of this level (high temperatures are around 300 degrees Fahrenheit), it is necessary to understand what degree of leakage control is required on the low temp end. However, there may be an allowable leakage...
