What is the ASME pressure vessel inspection code?

A leading standard for pressure equipment and components worldwide, the ASME Boiler and Pressure Vessel Code (ASME Code) provides requirements for manufacturer certification and quality assurance. It sets rules for the design, materials, manufacturing, inspection, testing and operation of boilers and pressure vessels (including power boilers, heating boilers, nuclear facility components, fibre-reinforced plastic pressure vessels and transport tanks).

Why is the ASME pressure vessel inspection code important?

The ASME Code is recognised in over 100 countries. Manufacturing, repairing or altering your pressure equipment in accordance with the Code helps you to access opportunities in these markets. Affixing the ASME certification mark to your pressure equipment inspires greater confidence among your business partners, end users and authorities. The mark is regarded as the hallmark of acceptance that indicates conformity to the Code.
