2205 Duplex Forming Strain UG-79
2205 Duplex Forming Strain UG-79
(OP)
Hi, this is my first post... trying to validate a rolled shell to establish that it is within the limits set forth under UG-79. We will be having a plate rolled, 19"id x 3/4"thk x 10'lg, S31803 2205 Duplex. Forming strain(Fiber elongation) per UG-79-1 is ((50*0.75")/9.875")= 3.80%. Table UHA-44 (Requirements for Post-Weld Heat Treatment) does not list S31803.
Question: What is the Postfabrication Strain Limit for 2205 Duplex SS?

A side note... and possibly better asked in a new thread: "Is there something that can be positively said about the planar stresses that are induced in a roll-formed cylinder from plate (namely 2205 Duplex) used in an ASME Section VIII Pressure Vessel?

API TR 938-C references do's and dont's, additonal requirements to guarantee optimum corrosion resistance of duplex (codes tends to have little requirements resulting from metallurgical effects - this is where API kicks in), there links to the various code sectionsm, etc.
