Bonded seals for completion tools

Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.

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.

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 water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.

Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.
