How does it work?
The PD 5500:2012 specification refers to pressure vessels connected to piping by bolts, screws or welding, as well as supports, brackets and other direct attachments. It applies to vessels that are subject to electrical heating or heated process streams, but not vessels exposed to direct heat or flame. The specification can be used with equipment and systems designed or manufactured to BS 5500 or PD 5500. And the 2012 specification is also relevant to pressure vessels in use outside of the EU as well as those designed and manufactured under the Pressure Equipment Directive.
