High pressure rotary lip seals


High Pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. high pressure hydraulic seals is made with slip ring and o-ring/square ring.


It adopts a toothed section, which is easier to install. The two grooves are the same and interchangeable. They are used to seal the rod, shaft, pin and rotary joint with high-speed rotation or swing movement. They have the characteristics of high pressure resistance, wear resistance, high temperature resistance, resistance to most chemicals.


Advantages:

1. Simple groove, small dimensions.
2. Low fraction.
3. Good abrasion resistance, high temperature resistance.
4. Compatibility with various chemicals.

In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
