Regarding pipe grades and pressure resistance capacity
Thread Content
One of the specifications for chemical process pipelines is the pressure rating of the pipeline. The pressure rating of this pipe is generally indicated by suffixes such as 150, 300, and 600, along with the pipe material like CS and SS. I have a question: what are the pipeline pressures that the pipes corresponding to 150, 300, and 600 can withstand respectively? In other words, at what pressure of the material inside the pipeline is it necessary to use a 300 series pipeline, and at what pressure is it necessary to use a 600 series pipeline?
The design pressure is 150 Lb for pressures below 2 Mpa, 300 Lb for pressures below 5 Mpa, and 600 Lb for pressures below 10 Mpa. Each pipeline has its corresponding design pressure and operating pressure
