MULTI-STATION TEST BENCH FOR SUBMERGED GAS TESTING OF SHUT OFF VALVES DN 15...80 MM (½...3″)
PURPOSE:
• submerged gas testing of pipeline valves;
• testing of valve’s body for strength and density;
• gate tightness tests;
• environmental leakage tests (including gland seals).
TESTED ITEMS:
• cryogenic valves;
• gate valves;
• stop valves (globe valves).
TESTED UNIT CONNECTION TYPE:
• flanged (according ASME B 16.5, GOST 12815 etc.);
• welded ends (according ASME B 16.25, GOST, etc.).
ADVANTAGES:
■ The tank, power rack, piping and all parts of the test bench that are submerged under water are made of stainless steel. The two-sided gate seal tests do not require the tested valve rearrangement, which significantly reduces the test time. Test from one to five valves is executed simultaneously.
■ The clamp of tested valves is made by hydraulic cylinders mounted on each test station, independently of each other.
■ The power frame is disposed within the water tank and submerged under water to a depth from 0 to 600 mm (24″).
■ For easy installation of valves to be tested the power rack rises above the tank.
■ For easy inspection of tested valves the tank of the test bench is provided with an internal illumination.
■ The test preparation time is significantly reduced by using the high-pressure quick-connect hoses.
■ Stainless steel power rack of test bench is actuated by two pneumatic cylinders.
