Pipeline material and valve pressure rating
Thread Content
Dear experts, what material should be used for pipelines carrying a mixture of hydrogen and hydrogen chloride at 2.1 MPa and 250°C? 20#? 304? What pressure rating should be chosen for the valve? 25KG(f)？ 40KG(f)？
For hydrogen and hydrogen chloride mixed gas pipelines at 2.1 MPa and 250°C, 304L is a suitable material; the pressure rating for the valves should be 40 KG(f)
Reply to 1# feibiao101: For a mixture of dry hydrogen and hydrogen chloride gases, 20# steel can be used; valves should be of 40Kg grade

I would like to ask: For steam pipes operating at 1.5 MPa and 180°C, is it acceptable to use seamless carbon steel pipes? Please advise
What standards are used? Or experience?
