In addition to stainless steel pipes, are carbon steel pipes optional? The maximum test pressure of GB5310 and GB9948 of DN32 is 20MPa, the maximum test pressure of GB8163 is 19MPa, and the maximum test pressure of GB6479 is 32MPa. Please recommend and add. Thanks!
Use American standard A106B pipe SCHXXS grade, the pressure can reach 42Mpa

Studying* In China, we have done a high-pressure hydrogenation, and all the pipes used are American standard pipes. American standard products are relatively complete.
Natural gas can be made of carbon steel or stainless steel. Just confirm the wall thickness under the condition of 35MPa.
We are using gb6479
