If no leakage occurs after 30 minutes, retain the pressure for 24 hours. The expected result is that the pressure drop is less than 0.01 MPa and the pipe does not leak. Then, release the pressure in the pipe. Release the pressure in the pipe, manually close the chilled water valve. ...
OUTLET OF AIR FOR WATER PRESSURE TESTNo information.HWANG, BONG - JU
Adjust the air exhausting speed until no air flows out of the valve. Then close the exhaust valve. (If a leakage test with nitrogen has been performed, skip this step.) Raise the water pressure in the chilled water pipe to 0.8 MPa. If no leakage occurs after 30 minutes, retain the pr...
The test is carried out under water because___. A. the pressure under water is greater than in the air B. the first Comets exploded in the water C. it will be easier for engineers to find out where the crack is D. that can protect the testers from being injured 相关知识点: 试题...
Water pressure test(水压测试) When the water and electricity are checked and accepted When all the water pipes are properly welded, they can be tested, and all the plugs must be blocked prior to pressure measurement. All valves shall be closed and the valves of the water inlet manifold ...
