In 1916 ASME began its program for certification to companies in the pressure equipment industry. This program was developed to certify quality control systems for the design, fabrication, assembly, and inspection of boiler and pressure vessel components during construction.
Products manufactured by ASME BPVC certificate holders include a certification mark in accordance with the applicable certified section also known as a “U” stamp. A company can also be certified to make repairs or alterations to pressure vessels under the National Board of Boiler and Pressure Vessel Inspectors under an “R” stamp.
Ledwell began building pressure vessels, or in our case DOT Cargo Tanks, in the spring of 2010. This past May, we successfully completed our 5th joint review for ASME and National Board certification.
The purpose of the review is to evaluate the quality program and ensure the implementation for each product manufactured for fabrication, alterations, and repairs. Each assessment ensures the applicant’s quality program is implemented successfully and complies with requirements based on the ASME standard.
Certificates are granted after a review of the previous 36 months of work, verification of record-keeping requirements, personnel training, and required knowledge of pressure vessel design and fabrication rules.
