Interventek has completed the current API-17G specification shear and seal test procedure with their new 20k (20,000psi) subsea in-riser Revolution Valve. The testing conducted fulfilled the requirements for Service Specification Level (SSL) liquid and gas.
Independently witnessed and verified, the trials demonstrated the shear and seal safety valve was able to surpass the challenging demands of the imminent API-17G standards for a wireline/coiled tubing class shear and seal valve. The valve has completed six cut sequences comprising slickline, braided cable and coiled tubing with braided cable followed by low and high-pressure liquid and gas seat tests after each sequence. The full test program was completed with no disassembly or redress at any point.
The 5⅛ inch, 20k Revolution Valve is the oil and gas industry’s first in-riser shear and seal valve designed for ultra-high pressure, high temperature (HPHT) operations.
The 20k product application is designed to be able to withstand working pressures of 20,000psi and temperatures up to 350 degrees Fahrenheit. It has a 5⅛ inch bore size and is able to cut wireline and coiled tubing up to 2. inch x 0.203 inch, 130ksi minimum yield strength.
