Manhole per UG-11
Manhole per UG-11
(OP)
I am building an ASME Sec 8 vessle that is equiped with two manholes w/covers. One is located in the head and one in the shell. These manholes were purchased from a vendor of ours and we received them without a data report. I am being told by the vendor that per UG-11 the data reports are not needed. But what I dont understand is that the manhole frame has a long seam that was welded. UG-11 (a)states that manhole frames and covers, that are WHOLLY formed by casting, forging, rolling, or die forming shall not require inspection, identification in accordance with UG-93(a) or (b), or partial data reports.





RE: Manhole per UG-11
Are these manholes made out of standard flanges welded on fabricated necks (i.e. rolled & welded plate)? If yes, then the applicable paragraph is UG-11(c).
