Multi-station test bench for submerged gas testing of shut off valves DN 15...80 mm (1/2...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 16037, 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.
