Dear masters: Hello, I’m facing a problem right now. Given that the outer diameter of the pipe is 3/8 inch, the wall thickness is 0.065 inch, and it is made of stainless steel (with an allowable stress of 138 MPa), how can the corresponding pressure be determined? I hope all the experts can give me more guidance. Thank you!

Is this a gauge tube? Go and look up the corresponding manufacturer. If it is a Swagelok product, the pressure can reach 6500 psig.

The first formula for pressure pipelines.

Mine is a thick-walled cylinder, so the formula mentioned in B31.3 does not apply; what should I do?
