UNS UHS piston rod seal

Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.

JST manufactures well service plunger pump packings in a wide variety of materials to suit specific well conditions and operating parameters, they are available in a wide range of elastomeric materials and high performance resins, including NBR, HNBR, FKM, filled PTFE, fabric reinforced rubber.  to suit specific well conditions, operating parameters, and fracturing fluids.

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.

The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.

The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.

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.

The ESA valve rubber seal is a type of Polypak, it combines a rubber o-ring type and a conventional lip type seal to produce a unique sealing device.
