What is the allowable stress of L245 welded pipe under high temperatures in terms of its mechanical properties? ? ? ?
Thread Content
In which standard can I find the allowable stress of L245 tubing at 300 degrees Celsius? ? ? Used for pipeline design. . It was not found in GB9711. . . . . It’s not listed in ASME B31.3 either :( What is the equivalent grade for L245 in ASME B31.3? .
It can be found in GB/T 20801; the 2020 version will come into effect in a few days, and the allowable stress values are slightly higher than those in the 2006 version
Okay okay, thank you so much:D
GB/T 20801.2-2021
