This European Standard specifies requirements for the design, materials, manufacturing and testing of pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100 bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements, bosses etc. The allowable grades do not include lam...view more

This Part of this European Standard specifies requirements for the design of unfired pressure vessels covered by EN 13445-1:2009 and constructed of steels in accordance with EN 13445-2:2009. EN 13445-5:2009, Annex C specifies requirements for the design of access and inspection openings, closing mechanisms and special locking elements. NOTE This Part applies to design of vessels before putting into service. It may be used for in service calculation or analysis subject to appropriate adjustment.

This European Standard specifies requirements for:
a)   routine inspection, periodic inspection and requalification of fixed LPG storage pressure vessels of sizes greater than 13 m3, and associated fittings;
b)   marking pressure vessels and/or keeping records, as appropriate, as a result of routine inspection, periodic inspection and requalification.
This European Standard excludes refrigerated storage.

Amendment to Annex J for Tubesheets

This document is intended for the application of AT on metallic pressure equipment during controlled
loading.
Therefore the overall aims of this document are:
— to detect, locate and grade areas with evolving imperfections;
— to provide the manufacturer the possibility to compare results of the first test with those of
subsequent periodic inspections;
— to determine the possibilities and limits of AE testing (AT) for pressure equipment;
— to establish common basis for procedures to perfor...view more
