22、g “Unfired pressure vessels” comprises the following Parts: Part 1: General. Part 2: Materials. Part 3: Design. Part 4: Fabrication. Part 5: Inspection and testing. Part 6: Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast ir
23、on. CR 13445-7, Unfired pressure vessels - Part 7: Guidance on the use of conformity assessment procedures. Although these Parts may be obtained separately, it should be recognised that the Parts are inter-dependant. As such the manufacture of unfired pressure vessels requires the application of all
24、 the relevant Parts in order for the requirements of the Standard to be satisfactorily fulfilled. Corrections to the standard interpretations where several options seem possible are conducted through the Migration Help Desk (MHD). The Help Desk can be found at www.unm.fr/en13445en which includes a d
25、ownloadable form for questions and instructions on how to submit a question. After subject experts have agreed an answer, the answer will be communicated to the questioner. Corrected pages will be given specific issue number and issued by CEN according to CEN Rules. Interpretation sheets will be pos
26、ted on the website.

28、 Copy, (c) BSI EN 13445-1:2002 (E) Issue 28 (2007-08) 4 Introduction EN 13445 specifies the requirements for design, construction, inspection and testing of unfired pressure vessels. It defines terms, definitions and symbols applicable to unfired pressure vessels. NOTE In EN 13445 the term pressure
29、vessel includes the welded attachments up to and including the nozzle flanges, screwed or welded connections, or the edge to be welded at the first circumferential weld at connecting piping or other elements. The term unfired excludes vessels that are subject to direct generated heat or flame imping
30、ement from a fired process. This does not exclude vessels subject to electrical heating or heated process streams. In Parts 2 to 5 only pressure vessels manufactured from steels and steel castings as detailed in Part 2 of this standard are covered. Parts 6 and 8 specifically deal with vessels of sph
31、eroidal graphite cast iron and aluminium, respectively, where special considerations apply. Part 1 This part contains general information on the scope of the standard as well as terms, definitions, quantities, symbols and units which are applied throughout the standard. Part 2 This part deals with t
32、he general philosophy on materials, material grouping and low temperature behaviour. It is limited to steel with sufficient ductility and, for components operating in the creep range, sufficient creep ductility. Part 2 also provides the general requirements for establishing technical delivery condit
33、ions and the requirements for marking of material. Part 3 This part of the standard gives the rules to be used for design and calculation under internal and/or external pressure (as applicable), local loads and actions other than pressure. The rules provided are both design by formulae (DBF), design
34、 by analysis (DBA) and design by experiment (DBE). The part also sets the requirements for when fatigue analysis must be performed and the rules to be followed when this is the case. Part 4 This part is based on existing good practice in previous national European Standards on manufacturing. It cove
35、rs forming, welding procedures and welding qualification, production testing, and post weld heat treatment and repairs. Rules are also provided for material traceability and tolerances. Part 5 This part covers all those inspection and testing activities associated with the verification of the pressu
36、re vessel for compliance with the standard, including design review by the manufacturer and supporting technical documentation, NDT and other inspection activities including document control, material traceability, joint preparation and welding. The level of testing is driven by the selection of the
37、 vessel testing group. Basically, the testing group determines the level of NDT and the joint coefficient used in the design. In terms of NDT, the overall philosophy has been the general adoption of EN ISO 5817:2003 quality level C for predominantly non-cyclic loaded vessels and level B for vessels
38、subject to cyclic loadings.

39、sting of pressure vessels made from spheroidal graphite cast iron. In general the rules in the relevant parts of parts 25 apply with additions and exceptions outlined in this part. Part 7 This part gives guidance on how to use the conformity assessment procedures in the Pressure Equipment Directive
40、97/23/EC. It is not a standard, but merely a CEN Technical Report. Part 8 This part contains special rules for material, design, fabrication, inspection, and testing of pressure vessels made from aluminium and aluminium alloys. In general the rules in the relevant parts of parts 25 apply with additi
41、ons and exceptions outlined in this part. Part 9 This part details the conformance of the whole EN 13445 series to ISO/FDIS 16528-1 “Boilers and pressure vessels Part 1: Performance requirements“. This is a CEN Technical Report. The first edition is limited to vessels of steel construction, but will
42、 be amended later to include spheroidal graphite cast iron and aluminium.

It also cont
44、ains instructions on how to use the standard (Annex A) as well as an index which covers the whole standard (Annex B). This information is aimed to aid the user of the EN 13445. This European Standard applies to unfired pressure vessels with a maximum allowable pressure greater than 0,5 bar (0,05 MPa
45、) gauge but may be used for vessels operating at lower pressures, including vacuum. NOTE The selection, application and installation of safety related accessories intended to protect pressure vessels during operation are covered in EN 764-7. 1.2 Exclusions This European Standard is not applicable to
46、 pressure equipment of the following types: a) transportable pressure equipment; b) items specifically designed for nuclear use, the failure of which may cause a release of radioactivity; c) pressure equipment intended for the generation of steam or superheated water at temperatures higher than 110
47、C; d) vessels of riveted construction; e) vessels of lamellar cast iron or any other materials not included in parts 2, 6, or 8 of the standard; f) multilayered, autofrettaged or pre-stressed vessels; g) pipelines and industrial piping.
