ASME Boiler and Pressure Vessel Code (BPVC) is the most widely used standard in the international market and has been recognized by many countries and regions in the world. Holding an ASME certificate can prove that the management and technology of the enterprise have reached the international level. At present, most of the projects in the world are required to hold the ASME authorization certificate, and its recognition is far higher than that of the European Union and other related certifications. Nameplates are stamped U/NB* and full ASME documentation is available.
