Consequences of high-pressure gas entering low-pressure pipelines

It’s too dangerous! ! ! I remember that this kind of situation occurred back then; according to the standards, the temporary procedure for switching to Unicom requires the use of blind plates. However, while busy with the process of replacing and starting up the equipment, communication issues led to the gas leaking from the compressors in the compression plant being CO; at that time, a female worker was found collapsed on the ground. Although the pipe you have installed can withstand this pressure, it doesn’t mean that the connected equipment, fittings, and other facilities can also handle this pressure. This is a major near-miss accident! Several times the normal pressure – it’s truly terrifying,,,,, Are the thicknesses of seamless carbon steel pipes the same? Valve? Flange? Equipment? What about their stress tolerance? ? ? Don’t emphasize that there’s no pressure buildup at the back – do you even know how much overpressure there is? What consequences will high-speed flow of flammable gases have? ? ? A kind suggestion: if it’s your fault, admit it quickly, find a place and some people to celebrate with,,,

It’s dangerous – pipes can burst and the low-pressure system can fail

The fact that no pressure build-up occurred indicates that the backflow mechanism provided some level of buffering; it’s also possible that protective devices such as safety valves activated. It is recommended to conduct more leak checks

The valve cannot be closed, the safety valve has opened, there is leakage at the flange sealing surface, and the pipeline is vibrating!

If an accident occurs in such a situation, it will definitely be a major accident, as natural gas is flowing inside.

Burst pipe – what other consequences could there be! This kind of accident has happened more than once
