Applications:

A safety valve is a type of valve that automatically actuates when the pressure of the inlet side of the valve increases to a predetermined pressure, to open the valve disc and discharge the fluid. The safety valve system is designed to be a fail-safe so that a wellbore can be isolated in the event of any system failure or damage to the surface production-control facilities.

In most cases, it is mandatory to have a means of closure for all wells capable of natural flow to the surface. To meet this requirement, a subsurface safety valve (SSSV) can be installed. This safety valve can be operated on a fail-safe principle from a control panel located on the surface.

The SSSV is connected to a control line, which is typically constructed of stainless steel components and is introduced into the wellbore at the time of completion. Depending on the specific circumstances, the pressure on the control line must be as high as 10,000 psi, to keep the valve open.

Aside from applications for SSSV, the same control line system can be used for a variety of other tasks, such as: 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; and geothermal coiled alloy tubing for energy production.
