Help with pipeline material selection
Thread Content
The logistics is about 0.3MPa steam. Can anyone tell me what material is best for the pipeline? It is safe and saves money. Thank you.
20# seamless pipe. See SH3405-96
For steam, just use Q235-B welded steel pipe... The pressure is not high at 0.3MPa. It depends on the diameter of your pipe. The thickness of the pipe does not need to be too high. If there are valves, flanges, gaskets, fasteners, etc. The valve should be a heat-resistant stop valve with any flange. The gasket should be a flexible graphite composite gasket (do not use asbestos board and rubber). The fasteners should be ordinary single-head bolts of grade 8.8.
