How to select the material and model for the valve flange cover of this pipeline
Thread Content
There is an existing hyperbaric oxygen pipeline, with the main pipe having a diameter of DN32 and the branch pipes having a diameter of DN10. The operating temperature is normal temperature, and the pressure is 15 MPa. What type of valves and flanges should be chosen? What are the models and materials? Please help me; thank you in advance!
You dare to connect oxygen pipelines with flanges too; you’re really bold. In addition to the regular high-pressure cut-off valves, upper and lower interlock cut-off valves must be added. Everything must be welded; flanges are not allowed, from a process perspective.
There are specific design specifications for oxygen stations that you can refer to. The form of a valve is related to its purpose, as well as to the material and flow rate. But carbon steel should not be used.
