After the completion of the hydropower project, the most important thing is acceptance, because the result of acceptance determines the quality of home life in the future. If the acceptance is not careful, especially the water pressure acceptance test, it is easy to cause some post-mortem complications that we regret. It is small today. Edited for everyone to talk about, in the suppression test should pay attention to what the problem! What are the errors we don't know?
First, the pressure is not as great as possible
Some homeowners tried to test the waterway to withstand pressure and hit the water pressure high. However, this may cause the pipeline to exceed its limit, but it will lead to the risk of water leakage in the future;
Only one pressure test can not completely determine whether the waterway is in normal use, because the first time the air pressure will be discharged. By repeatedly suppressing pressure, it is possible to continuously test accurate water conditions.
Third, it can be waterproof without acceptanceThe waterway groove and the bathroom floor can be waterproofed once, but no water storage test is required. After the tank is sealed, a more complete waterproof layer will be made.
As future decoration and maintenance information;
Fifth, sealing slots must be tight
The cement that closes the channel (it cannot be putty) must be consistent with the cement of the original structure to ensure its strength.
Hydropower acceptance
Frequency welded pipe characterized by: welding speed large and welding heat affected zone small, weld the workpiece may not clean up, can weld thin-walled tube, can weld metal pipe.Production process depends mainly on the variety of materials, from raw materials to finished products need to go through a series of processes, these processes need kinds of machinery and welding equipment, electrical control, testing equipment, such equipment and fittings in accordance with a different process requires more reasonable arrangement, high frequency welded typical process: Slitting - unwinding - strip leveler - head and tail cut - steel welding - looper accumulator - forming - welding - deburring - sizing - testing - fly cut - initial inspection - straightening steel - pipe processing - hydrostatic test - flaw detection - printing and coating - finished.
