Pressure vessel design codes

A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous, and consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation.

The design and certification of pressure vessels is governed by the following design codes which Spirotech-SRD adhere to: BS 5169; PD 5500; EN286 (Part 1); Lloyds Class 1, 2/2 & 3; Bureau Veritas; Det Norske Veritas; ASME VIII Code, EN13445 and most other well known specifications.
