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.

The ASME (American Society of Mechanical Engineers) code for shaft design primarily falls under the ASME B31 series for piping and the ASME Y14.5 for dimensioning and tolerancing. While there isn't a specific ASME code exclusively for shaft design, relevant guidelines can be found in ASME B107 for tools and ASME B30 for cranes and lifting devices. Additionally, the principles of stress analysis, fatigue, and material selection are essential in the design process, often using methodologies outlined in the ASME Boiler and Pressure Vessel Code (BPVC). These codes ensure safety, reliability, and performance in mechanical design and applications.
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
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 pig launcher is a type of pipeline product. It requires an ASME U stamp in order to be properly certified.
The design should conform to ASME Sec VIII Div.1.
Someone who holds of an "R" stamp as required by the ASME
Yes, a U stamp is required on pressure vessels, including tanks, that are constructed in accordance with the ASME Boiler and Pressure Vessel Code. The U stamp indicates that the vessel has been designed, fabricated, and inspected to meet the rigorous standards set by ASME for safety and reliability. This certification is essential for compliance with regulatory requirements and for ensuring the vessel's integrity during operation.

A UM stamp refers to a "United Methodist" stamp, often used in the context of the United Methodist Church for various purposes, such as fundraising or promoting church events. It may also refer to stamps issued by the United Nations, denoting support for various global initiatives. In philately, collectors might refer to any stamp related to United Methodism or United Nations themes as a "UM stamp." The specific meaning can vary based on context.
OK um well there is no such um thing but I think it means the recycling plant.
ASME was created in 1880.
Of course just conract the AWS and ask for someone locally who has an "R" stamp from the ASME section IV qualifications
