Application

In most cases, it is mandatory to have a means of closure for all wells capable of natural flow to the surface. The installation of a subsurface safety valve (SSSV) will provide this emergency closure capability. Safety systems may be operated on a fail-safe principle from a control panel located on the surface.

The SCSSV is controlled by a ¼” stainless steel control line that is attached to the outside of the well tubing string and installed when the production tubing is installed. Depending on the wellhead pressure, it may be necessary to keep as much as 10,000 psi on the control line to keep the valve open.

Other applications:

Capillary coiled alloy tubing for chemical injection

Bare and encapsulated hydraulic control line coiled alloy tubing for subsea safety valves

Velocity strings, work strings, and steel tube umbilicals

Geothermal coiled alloy tubing

Encapsulation Features
