PD 5500:2009+A2:2010 Specification for unfired fusion welded pressure vessels £1,800.00 Specification for unfired fusion welded pressure vessels ISBN: 9780580648861 Publication Date: January 2009 Pagination: 904 Replaces: PD 5500:2006+A3:2008 PD 5500:2009 Specification for unfired fusion welded pressure vessels specifies requirements for the design, manufacture, 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. This new edition can be used:to support equipment and systems previously designed and manufactured to BS 5500 or PD 5500 for pressure vessels intended for use outside the European Union for vessel design and manufacture where the Pressure Equipment Directive is applicable but where BS EN 13445 does not provide an appropriate solution The BS EN 13445 series provides the definitive European Standards for unfired pressure vessels. 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. The 2009 edition will include all the corrigendum and amendments made during the last three years to PD 5500:2006, resulting in a new, unmarked publication.Key 2009 revisions to PD 5500: Revisions to material grouping designations in line with PD CR ISO 15608:2000 Revisions to calculation of tubesheet ligament efficiency taking account of untubed area Improvements to alternative method for loads on nozzles in cylindrical and spherical shells Updating of references for new and revised European standards. Enquiry cases have also been added, covering external loads on flanges, flexibility of the nozzle-vessel interface and guidance on alternative rules for nozzle reinforcement. This is the start of new three-year cycle including updates and new enquiry cases. The three-year subscription to PD 5500 includes free regular updates as amendments are made to the specification.
