Seal stack for well tools sliding sleeve


In many well completion operations, it frequently occurs that it is desirable, either during the completion, production, or workover stages of the life of the well, to have fluid communication between the annular area between the interior of the casing and the exterior of the production tubing or workstring with the interior of such production tubing.


A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.


In such well tools, a series of upper and lower primary seals are placed in the housing for dynamic sealing engagement relative to the exterior of a sleeve which passes across the seals during opening and closing of the port element. As with the seal stack, such primary sealing means also represent an area of possible loss of sealing integrity.


Application:

1. FLS and FLS-R Gate Valves

2. Well tools like sliding sleeves that can be used for infinitely adjustable switches

2. Bi-directional pressure bearing piston or rod seal



Features:

1. High temperature and high pressure resistance

2. Bidirectional alternating pressure bearing

3. Reciprocating seal

4. High reliability - verification of over 2400 reciprocating tests

5. JST patented seal design

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.

Cryogenic valve seals

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.
