How should pressure pipelines be handled when passing through deformation joints?
Thread Content
It is common to see flexible joints used when water supply and drainage pipes pass through expansion joints. What measures are required when pressure pipelines pass through deformation joints? It seems none of the regulations address this aspect~~
It depends on the operating pressure of the pipeline; for low-pressure pipelines, hoses and expansion joints can be used to handle it. Use it flexibly.
What about high-pressure pipes? Or are they pipes with high levels of danger, such as being toxic or flammable? How should such pipes be handled?
Pipe racks are installed on both sides of the settlement joint, while expansion joints are used at the settlement joint. Pressure pipelines use expansion joints as well as tension bends
Without hoses, for the double columns on both sides of the settlement joint, a pipe rack is installed only on one side; the settlement deformation is absorbed through the span of the pipes (i.e., the large distance between the pipe racks).
