Stainless steel ball valve

Thread Content

Stainless steel ball valve: after the water pressure meets the requirements. After some time, if pressure testing is done again, will there be leaks?

Normal storage for half a year is generally fine; of course, for safety reasons, it’s advisable to conduct another pressure test after a longer period of storage to ensure safety!

Don’t all online ball valves need to be pressure-tested individually after a certain period of time? Where’s the promised normal performance?

That’s a great question! Do you have to perform a pressure test every time it’s used, right? ? ?

Each case is handled on a case-by-case basis. Every valve is pressure-tested before leaving the factory, and 20% of them are still sampled upon arrival at the client’s site to ensure they meet the required standards.

Is this random inspection intended to prevent damage to the valves during transportation, or is it due to a lack of trust in the manufacturer?

The damage is usually to the appearance; random inspections are not a sign of distrust, but rather a way to ensure quality.

Is the valve seat material imported? If so, the problem should not be serious; it’s hard to say the same for materials available domestically. Apart from the reliability of the designed data, it is mainly a matter of the material used for the seals. Another question: I wonder if, when conducting pressure tests, you simply perform them once or twice, and consider it successful as long as there is no leakage. For a reliable pressure test, I recommend conducting it several times, with a longer holding time for the pressure. If not, it means the material of the sealing ring is suitable.

Why smart? ? ? What caused it, huh? More people are welcome to join the discussions
