Large gap ultra-high-pressure sealing components (Type D）

Ultra High Pressure (UHP) seals are specialized seals designed to withstand high pressure conditions, typically above 20,000 PSI (1379 bar). They are commonly used in applications such as oil and gas exploration, hydraulic systems, and chemical processing. UHP seals can be made of materials such as polytetrafluoroethylene (PTFE), carbon-graphite, and other high-performance polymers. The design and material selection of UHP seals must consider factors such as pressure, temperature, media compatibility, and sealing dynamic performance to ensure reliable and long-lasting performance.

Product Information

The high pressure sealing assembly consists of a polyurethane seal and a fan-shaped support. It is mainly used for pressure testing of steel pipe by hydraulic tester. In the non-working condition, a gap exists between the seal and the surface of the steel pipe. During the test, hydraulic oil is applied to the surface of the seal ring. Then the ring is compressed and the surface of the steel pipe is tightly wrapped, and the test pressure can be performed. It is suitable for pressure test of steel pipe such as casing, oil pipe and natural gas pipe. Also used for leak detection of steel pipes, joints, welded joints and sealing of high pressure valves.

Benefits

Lip optimization: the lip fits more closely to the groove surface under peripheral pressure, and the higher the pressure, the better the lip seal.

Scalloped bracket shrinks and expands radially with the seal while increasing the strength of the seal.
