I have a small pressure vessel (UM type stamped) vessel (a small air compressor receiver). Under the the stamp and under "W" for welded construction are the following "SH.094" and "HD.094". I no longer have access to copies of Section VIII Div. 1 code being retired. What are the notes "SH.094" and "HD.094" telling me?
