Why is the ASME Stamp so Important?

The ASME stamp standardizes the level of quality that is required in these types of vessels and it’s considered an industry best practice to use ASME certified vessels. In fact, some states have passed legislation that requires pressure vessels operating at 15 psi or higher to be built in accordance with ASME boiler and pressure vessel code.
