ASME BPVC – XIII -2021 BPVC Section XIII, Rules for Overpressure Protection
Published By | Publication Date | Number of Pages |
ASME | 2021 |
This Section covers requirements for construction and continued service of pressure vessels for the transportation of dangerous goods via highway, rail, air or water at pressures from full vacuum to 3,000 psig and volumes greater than 120 gallons. “Construction” is an all-inclusive term comprising materials, design, fabrication, examination, inspection, testing, certification, and over-pressure protection. “Continued service” is an all-inclusive term referring to inspection, testing, repair, alteration, and recertification of a transport tank that has been in service. This Section contains modal appendices containing requirements for vessels used in specific transport modes and service applications. Rules pertaining to the use of the T ASME Product Certification Marks are included. Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.
