An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
U and R stamps are ASME codes certification Stamps, qualifying organisations for the manufacture(ie fabrication) and repair and/or alteration of pressure vessels-in line with ASME boiler and pressure vessel codes(check ASME IX, ASMEViii Div 1). The U stamp is for fabrication of pressure vessels and the R stamp is for repair and/or alteration of pressure vessels. These are stamped on the finished work signifying complete compliance with the code requirements. (Contribution from Michael Obinna Okoye odu-Nigeria)
An ASME U Vessel Stamp signifies that the vessel was made to the standards stated in Section VIII Division 1 by the American Society of Engineers. A U2 Vessel Stamp means it meets the standards for Section VIII Division 2 Alternative Rules.

An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
The pig launcher is a type of pipeline product. It requires an ASME U stamp in order to be properly certified.
The ASME U stamp designates an unfired pressure vessel of more than 35 gallons (4.68 cu. ft.) has been built to ASME Code specifications, under ASME Code section 8. A U-1 form must be filed and signed by the authorized inspector for each and every pressure vessel built. The ASME U2 stamp is for unfired pressure vessels not built to ASME section 8 div. 1 standards, but under the alternative rules, has been inspected and found to comply with acceptable construction methods. A U-1 form signed by an authorized inspector must be filed for each such vessel, along with a description of the methods of construction used. The ASME U3 stamp is for high pressure (over 600 psi?) unfired pressure vessels. The ASME UM stamp is for pressure vessels less than 35 gallons capacity.
The design should conform to ASME Sec VIII Div.1.

ASME was created in 1880.
What is difference between ASME B16 & ASME B16.5 Flange
OK um well there is no such um thing but I think it means the recycling plant.
Of course just conract the AWS and ask for someone locally who has an "R" stamp from the ASME section IV qualifications
