What are ASME Codes and Why are they Important for Pressure Vessels?

Pressure vessels since the very first day of their application have been performing this challenging role of holding elements (gas, liquid or semi solid materials) at pressure levels substantially different from the ambient pressure. These strategically constructed cylinder-shaped closed containers are expected to be built with extreme care and exact specifications and features, as any loophole in the construction or feature can lead to leakage or explosion, which can be fatal in nature. No wonder that the aspects such as design, features, manufacture and operation of pressure vessels are regulated by the engineering authorities backed by legislation.
