Regarding whether particle pipelines require grading
Thread Content
Dear colleagues, the pipes falling from the pipes at the bottom of the silo into the powder conveying system have a design pressure of 1 and an operating pressure of 0.02. Is it necessary to classify these pipes?
If the design pressure of the pipe is 1 MPa and the operating pressure is 0.02 MPa, it is generally still necessary to stage the pipeline to ensure safety. It is recommended to refer to relevant pressure pipeline standards and safety specifications for classification. .
