Elliptical manway
Elliptical manway
(OP)
Gentlemen- What has been your experience on acceptability by U-Stamp certificate holders and also by Authorized Code Inspectors of an elliptical manway supplied under UG-11 for an ASME Section VIII, Div. 1 component. Specifically for the cover and the ring can be easily calculated to meet Code.
UG-11 (2015 Edition) states that the manufacturer of the vessel is responsible for the suitability of the design in meeting the rules of the Code.
1. Is certification by the elliptical manway supplier adequate for pressure and temperature rating to satisfy Code rules?
2. Is the elliptical manyway supplier responsible for providing the method used including backup documentation that the manway cover meets the requirements of the Code?
3. If the elliptical manway supplier wled an no pressure retaining clip to the manway cover does he have to provide certification that the welding procedure qualification and the welders themself are qualified per ASME Section IX?
4. Is anyone aware of any suppliers who can provide an ASME Code Section I, IV, or VIII, DIv. 1 stamped and certified as "PART" elliptical manway?

FYI 1)Elliptical man ways & hand holes have been acceptable for years to Section I & VIII A.I.'s.
2)U stamping and Partial Data Reports are not necessary for assemblies certified to UG/PG-11.
3) A certificate of conformance from the manufacturer is required and all that is required by Code. It should state that welding was performed by qualified welders to qualified procedures etc., etc., etc...
4) The Code does not have calculations for the pressure ratings for these parts, so the MAWP is determined by UG-101 proof test.
5) CMF listed above can provide a Partial & Stamping but it is un-necessary per Code, however we know the customer is always right even if they are wrong.

They have the certifications you need.
