May I ask, according to the American standards, if I know that the pipe material to be used is ASTM A333 GR. 6. So how do we determine the material of pipe fittings and flanges, as well as the material specifications to be followed?
Fitting A420-WPL6 (standard ASME B16.9), Flange A350-LF2 Class 1 (standard ASME B16.5)
Hello, I would like to ask something. How was this material determined? Based on experience, or is there a table in some standard that can be used for lookup?
Check the ASME materials section, and consult the references
Hello. Could you please specify the standard number and the approximate location? Thank you.
Is there anyone else who can help answer this question? I went through ASME BPVC II and IX. No corresponding comparison table was seen
For the second edition of \"Design of Chemical Pressure Vessels – Methods, Problems, and Key Points\", Appendix 3 can be referred to.
Hello, I see you are referring to Appendix 3: Selection of Welding Materials. I took a look at this appendix; it doesn’t seem to be related to the question I asked.
Refer to Appendix 3-3, the Steel Classification Table, for the appropriate selection of various materials.
If a certain material is chosen for the steel pipe, the same material will be used for the fittings; if that standard material is not available, another material has to be used as a substitute
Fittings: A420WPL6; for flanges, use A350LF2CL1 if forged parts are used, or SA516Gr70N with an impact value of -46 degrees if steel plates are used. Wuhan Iron and Steel Panglong
