Pipeline connection issues for Class A flammable gases
Thread Content
With a working pressure of 1.7 MPa and a working temperature of 35 degrees, can high-pressure rubber hoses be used for connecting pipelines carrying Class A flammable gases? I would like to ask the fellow sailors. Thank you
What medium? Where is it used? It probably can’t be used. Specifically, it depends on the relevant specifications. Are you referring to chemical industry standards or gas industry standards, etc.? As mentioned above, the petrochemical standards have been outlined. According to the gas industry standards, rubber hoses may only be used when the pressure indoors is ≤0.2 MPa; there are also requirements regarding the length of such hoses.
The balance tube on the programmable valve: the original valve used a metal pipe of DN15, but it leaked frequently due to corrosion; therefore, it was replaced with a high-pressure rubber tube.
