Anti Corrosion Super Safety Downhole Safety Valve 8 Inch Alloy Steel SSV

Introduction of Super Safety Valve

The Super Safety Valve is a sort of Fail Safe Safety Valve for well testing from a land or jack-up rig. The SSV is normally run inside or below the Blow Out Preventer (BOP) and is used to control well flow. The ID is 3.0 in., OD is 8.0 in., and the working pressure of Super safety valve is 15,000 psi. This safety valve has a port for chemical injection downhole or to control a subsurface safety valve. It is capable of cutting wireline and coiled tubing using the nitrogen charge or by application of balance line pressure.

Features of SSV

* With two hydraulic lines and a chemical injection port, the super safety valve is designed to close by spring force but has a nitrogen charge chamber to quicken the closing time.

* The super safety valve has the ability to cut wireline and coiled tubing without the addition of balance line pressure.

* The safety valve is held open by maintaining hydraulic control pressure on the control line.

OPERATIONS GUIDELINES

Typically, the nitrogen charge chamber of the valve is charged with nitrogen to 1000 to 1500 psi. This charge is sufficient to cut 7/32 inch mono-conductor cable, but it is not adequate to cut coiled tubing. The valve can be charged with nitrogen sufficient to cut coiled tubing, but this raises the required hold open pressure. The tool is capable of cutting 1.50 inch OD x 0.125 inch wall thickness coiled tubing by application of balance line pressure. Halliburton T&T Engineering should be consulted whenever coiled tubing cutting is anticipated.
