How to pressure test the drain pipe and exhaust pipe? What are the requirements for test pressure?
Thread Content
There is no valve flange on the exhaust pipe. How to perform a pressure test on the pipe? The pressure required by the pipeline is not very high. How should the pressure be determined during a pressure test? I have this problem now and don't know how to solve it.
If the gas is dangerous, should I check for leaks?
The pressure test of the exhaust and emptying pipeline is performed together with the main line before the valve. There is no need to test the pressure after the valve, but the reliability of the valve must be ensured. If this is not guaranteed, a pipe cap must be used in the low-pressure system.
If this kind of pipeline does not have valves or other seals, there should be no need for pressure testing. Are there any specific regulations? Still have some doubts.
What should be done is to plug it with a plug first and then do the test. If it is toxic, you need to do the same pressure test as the pipeline pressure. If it is just a normal liquid or gas pipeline, then use about 2kg.
What about venting high points of combustible gas? Some have no valves, only flame arresters.
Plug the pipe ends with something, like when testing for leaks in a heat exchanger tube bundle.
Non-working pipelines generally do not require pressure testing.
Vent pipes that directly discharge into the atmosphere usually do not require strength testing, such as* * After the torch vent tube cylinder is installed section by section, there is no need to conduct a strength test.
It’s been a long time since I posted this. Everyone said very well, and I haven’t done any pressure testing. Supervising Party A also has no requirements.
Well, I think everyone should try it. We all do pressure tests
When we make gas pressure regulating equipment, there is basically no pressure test. However, there is a leak alarm device inside the equipment. Generally no problems arise here. Unless the bolts are not tight, this kind of thing has really happened.
What is the difference between an exhaust pipe and an exhaust pipe?
It depends on whether the main pipeline transports medium with higher pressure. If so, of course a pressure test must be performed when emptying. When testing pressure, the appropriate pressure should be selected according to the material to be evacuated.
