From the HVAC design to explain, to specific methods, please do not talk about the general, probably like, confused for a long time, please enlighten the gods ~ ~ ~ more
GB & lt; Code for acceptance of building water supply and drainage and heating construction & gt;
First, the warmth of the water pipe according to the design requirements of the experimental pressure (such as the design is not clear requirements of the experimental pressure are 1.5 times the working pressure, but not less than 0.6MPa) at the experimental pressure for 10 minutes, the pressure drop is not greater than 0.02MPa and then pressure To the work pressure, check the pipeline is not infiltration everywhere, do not leak for the above process will be completed in accordance with the above conclusions can be qualified or unqualified conclusions, and then the relevant personnel to confirm the second, warm duct main inspection duct, After the production of the mouth of the mouth, riveting holes, duct flange flanging, ducts between the tight links, inspection to the main, trunk-based. Different pressure levels of the ducts used in the test method of different low-voltage system can be used to test the light leakage method of the sea in the suppression of the Soviet Union to adjust the pressure system should be leaked in the leak test after passing the air volume test of the high pressure system all the air leakage If you feel useful, please use, worthlessly so hard
According to the design run pressure of 1.5 times to determine. Such as the design operating pressure 0.6MPa, test pressure 0.9Mpa.
