Specified Minimum Yield strength of the pipe
Specified Minimum Yield strength of the pipe
(OP)
What is the relationship between Specified Minimum Yield strength of the pipe and allowable stress value and which one must be considered in finding maximum allowable working pressure of the pipe?

do u know the same formula used for API ?

RE: Specified Minimum Yield strength of the pipe
Now, i am going to Maximum allowable working pressure of each section. I want to know wich part of API can help me to do. and which formula? i couldn't findn any formula like ASME 31.3 in API.
please advise me.
tnx

That dosn't sound like its a pipeline, refinery or power plant, so why are you looking for a "API" piping code to design excavation equipment?
Just because it might look like a pipe and have internal pressure does not mean you use a pipe design code. Pipe sections are sometimes used in structural design, but the structural engineers do not use a piping code.
Piping codes can have allowable stress up to 80% of yield strength. Excavation equipment components might be designed to only 25%-50% of yield stress.
