SA36 Attachments in Low Temp
SA36 Attachments in Low Temp
(OP)
A carbon steel vessel is made to Sect. VIII Div. I with MDMT -50°F.
The vessel has external attachments that are subjected to loads resulting in stresses on the shell or head.
Can such load bearing attachments be made from SA36 or even SA106B (not normalized nor impact tested), or must they be treated like all other pressure components such as nozzles?
Thank you

"Components such as shells, heads, nozzles, manways, reinforcement pads, flanges, tubesheets, flat cover plates, backing strips which remain in place AND ATTACHMENTS WHICH ARE ESENTIAL TO THE STRUCTURAL INTEGRITY OF THE VESSEL WHEN WELDED TO PRESSURE RETAINING COMPONENTS SHALL BE TTREATED AS SEPARATE COMPONENTS. EACH COMPONENT SHALL BE EVALUATED FOR IMPACT TEST REQUIREMENTS BASED ON ITS MATERIAL CLASSIFICATION THICKNESS.....
So, read the above carefully and evaluate for impact test requirements.

Another mighty contribution. A star to you.
