First successful test of dual-seal gate valve to API 6A HPHT standards
HOUSTON -- Worldwide Oilfield Machine (WOM) has announced the successful completion of an extreme high-temperature test of its patented dual-seal gate valve with a Magnum seal assembly. Conducted at its manufacturing facility in Houston, the test included operating the gate valve through 200 cycles of extreme temperatures ranging from -20° to +450°F, under a constant pressure of 15,000 psi.
The rigorous test was completed for the first time at this temperature range, exceeding previous tests at 350°F. Representatives of major oilfield service companies were present to observe and confirm the testing authenticity. This test ensures customers that the gate valve meets the American Petroleum Institute (API) 6A Annex F PR2 performance requirements, a stringent standard for individual equipment units containing pressure.
After completion of the test, key seal components within the valve’s upstream and downstream sides did not reveal any abnormal abrasion or deformation despite the extreme temperatures and pressures on the valve. Photos and recorded test results demonstrated that the mechanical integrity was maintained on both up and downstream seal assemblies, gate faces and the stem packings. The dual-seal technology developed by WOM forms a bubble-tight seal against the valve gate, which is maintained through the most extreme conditions such as those occurring in Arctic and ultra-deepwater drilling and production.
WOM is a vertically integrated, multinational oilfield and process equipment manufacturer, supplying a wide range of API-certified pressure and flow equipment, including ball and gate valves, check values, chokes, manifold systems, Christmas trees, intervention systems, blowout preventers, and wellhead/test equipment.
