  1. TAIEX Workshop on thePressure Equipment Directive Materials Bratislava 11/12/13 April 2005 Presented by Peter Hanmore For the benefit of business and people

  2. Material Requirements SUMMARY 1 Suitability 2 Joining materials 3 Essential safety requirements 4 Material source Certification Guidelines

  3. Materials 1 General Designer must select materials that are suitable for the expected application and intended lifetime Taiex - Bratislava April 2005

  4. Meet certain requirements both individually and in joined structure Joining procedure qualification & Coupon plate testing Materials 2 Joining materials Taiex - Bratislava April 2005

  5. Specified properties Same properties in weld and HAZ Sufficiently Ductile Compatible (galvanic) Sufficiently Tough Chemically resistant Suitable for intended processing Resistant to Aging Materials 3 ESRs Material Properties Selection Taiex - Bratislava April 2005

  6. Provide list of materials that demonstrates source: Materials Materials 4 Source Harmonized Standard European Approval of Material Particular Material Appraisal Taiex - Bratislava April 2005

  7. EN 10028 Pt 1 EN 10028 Pt 2 EN 10028 Pt 3 EN 10213 Pt 1 Steel castings Steel Plates EN 10028 Pt 4 EN 10213 Pt 2 EN 10028 Pt 5 EN 10213 Pt 3 EN 10028 Pt 6 EN 10213 Pt 4 EN 10028 Pt 7 EN 10222 Pt 1 Fasteners EN 10222 Pt 2 EN 10269 Steel forging EN 10222 Pt 3 EN 10216 EN 10217 Seamless & welded tubes EN 12420 EN 10222 Pt 4 Copper EN 12451 EN 10222 Pt 5 EN 12452 EN 12482 Aluminium Materials 4 Harmonised Standards Material Standards, e.g. NB. Manufacturer must still check suitability Taiex - Bratislava April 2005

  8. Materials 4 Harmonised Standards Product Standards, e.g. EN 12952 – Water Tube boilers EN 12953 – Shell boilers EN 13445 – Unfired Pressure Vessels EN 13480 – Industrial Piping Part 2 - Table A1or A2 Taiex - Bratislava April 2005

  9. Materials regularly used for Pressure Equipment Applied for by Manufacturer of PE or material Issued by Notified Body May take many months to publish in OJ New materials may require testing When approved may be used by any manufacturer Materials 4 EAMs Taiex - Bratislava April 2005

  10. Nickel 201 Four different product forms Hastelloy Plate in different alloys Alloy 600 Four different product forms Materials 4 EAMs EAMs Issued to date: Taiex - Bratislava April 2005

  11. Materials 4 PMAs Any material may be used providing: If specific quantitative requirements not met, justification required (equivalent overall level of safety?) Manufacturer ensures material is suitable for “particular” application and meets ESRs for material Notified Body performs particular appraisal for equipment in Cats III & IV Provide evidence of compliance with allowable specification, i.e. Harm Std, EAM, PMA No set format for documentation. Decisions made concerning one material do not have to repeated PMA Taiex - Bratislava April 2005

  12. Materials 5 Certification Materials must: Material Certification Cat 1 - (2.2) Cat II, III, IV - (3.1) • be accompanied by documentation issued by the material manufacturer affirming conformance to a specification. Cat 1 - Certificate of conformity Cat II, III, IV - specific product control - e.g. (EN 10204 - 3.1) -{prepared by material manufacturer} Taiex - Bratislava April 2005

  13. Materials 5 Certification Material manufacturer’s certificate acceptable only if: Material Certification e.g. ISO 9001-2000 Certification Body Established in EU Material manufacturer has Quality System, e.g. ISO 9000, approved by competent body established in EU, If not: independent witness, e.g. (EN 10204-3.2) Guideline 7/5 Taiex - Bratislava April 2005

  14. Joining Materials Welding Consumables • Appropriate properties • Certificate of conformity EN 10204 – 2.2 Certificates of conformity EN 10204 - 2.2 Not main pressure part unless failure causes catastrophic release of pressure Materials 5 Certification Bolting Taiex - Bratislava April 2005

  15. Materials 6 WGP Guidelines http://ped.eurodyn.com/ • Section 7 - Materials • 7/5 - Inspection documents when manufacturer does not hold appropriateQS approval • 7/17 – Impact testing • 7/19 - Components • 7/24 – Assured properties • 7/25 – Welded pipe Taiex - Bratislava April 2005

  16. The End Taiex - Bratislava April 2005
