The ASME® BPVC specifies a range of materials that are suitable for use in pressure vessels and boilers. These materials are often listed in the ASME® Boiler and Pressure Vessel Code, Section II, Part A, and other relevant standards
Radiographic Testing (RT) is a powerful NDE technique widely used in the manufacturing of pressure vessels and boilers. It involves the use of ionizing radiation to penetrate the material and create an image of internal features.
Non-Destructive Examination (NDE) is a crucial aspect of the manufacturing process for pressure vessels and boilers. It involves a variety of techniques to detect flaws and defects without damaging the material. For U-Stamp certified products, NDE is essential to ensure the integrity and safety of the equipment.
A U-Stamp is a certification mark issued by the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI). It signifies that a pressure vessel has been manufactured and inspected in accordance with the rigorous standards outlined in the ASME® Boiler and Pressure Vessel Code (BPVC).
Applicants for new issuance or renewal of an ASME® Certificate(s) of Authorization should be aware that the Joint Review will require implementation and demonstration of their Quality Control Program. The purpose of the demonstration is to have the Applicant provide evidence of their knowledge of and compliance with requirements of each Certificate and scope they are requesting.
The difference between the U designation and the UM designation is related to size. However, this is not the only difference between the two. UM designated pressure vessels are not required to undergo the same inspection regimen as the larger, U stamped pressure vessels.
Obtaining a U-Stamp or U2-Stamp from the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI) is a significant achievement for manufacturers and fabricators of pressure vessels and boilers. These certifications signify adherence to rigorous quality, safety, and performance standards.
