What is the required stress for L245 steel pipe at -10°? Everyone, let’s discuss it!
It can be found in Table A-1 of Appendix A to the Code for Process Piping (ASME B31.3). It should be 137 MPa; you can check it again on your own
L245 is a pipeline steel; the method for calculating the allowable stress of materials used in gas pipelines should refer to B31.8 rather than ASME B31.3. Alternatively, referring to the national standards such as the \"Design Code for Gas Pipeline Engineering\" and the \"Design Code for Urban Gas\", the allowable stress = minimum yield strength * design factor, with this design factor being determined based on the regional classification of the area where the pipeline passes.
