Specification for unfired fusion welded pressure vessels
This specification was developed by British Standards Institution (BSI) and has recently been published. In 904 pages you may find requirements for the design, manafacture, inspection, testing and verification of compliance for unfired fusion welded pressure vessels manufactured from carbon, ferritic alloy and austenitic steels, aluminium, copper and nickel used in a wide range of process and energy industry applications.
The Published Document provides the basis for vessel design and manufacture for Pressure Equipment Directive (PED) compliance. It contains:
• relevant dimensional diagrams and formulae for material determination
• requirements for materials, design, manufacture, inspection, testing and verification
• annexes and enquiry cases that provide guidance on its use in domestic and international markets.
The term ‘pressure vessel’ as used in this specification includes branches up to the point of connection to the connecting piping by bolting, screwing or welding, and supports, brackets or other attachments directly welded to the pressure-containing shell.
PD 5500 is applicable to vessels subject to electrical heating or heated process streams. It, excludes, however, those that are subject to direct generated heat or flame impingement from a fired process.
This publication includes all the amendments and corrigenda that were made to the previous edition – BS PD 5500:2006 – during last three years.
