Does anyone know of a US based manufacturer capable of making welded (not seamless) pipe, elbows, tees, etc. 12" and down that are compliant with the PED (stainless steel)? The main problem is the welding procedures; no one in the US has PED approved WPS. There are many manufacturers of...
There has been a bit of discussion of the merits/methods, etc. of stress linearization through a section of interest to extract equivalent membrane and membrane + bending stresses to compare to ASME Sec. VIII Div. II allowable values.
Someone had suggested looking at the stress intesity at...
When interpreting solid models in Ansys in relation to allowable stesses of Sec. VIII Div. I, is the following methodology reasonable for primary stresses?
1. Excluding discontinuiies in the structure, locate the section that appears to have the highest stress by a Stress Intensity or von Mises...
I am unable to find a (non-FEA) method for determining the shell and ring stresses of a single ring subjected to a longitudinal force and moment (usually at four points, 90 deg. apart), that is welded to a shell (usually 12-48" OD). I can find formulae for double rings and rings that have...
