1 For the benefit of business and people
TAIEX Workshop on the Pressure 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 Designer must select materials that are suitable
1 Materials General Designer must select materials that are suitable for the expected application and intended lifetime Taiex - Bratislava April 2005

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

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

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

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

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

9 Materials 4 EAMs 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 Taiex - Bratislava April 2005

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

11 Any material may be used providing:
4 Materials 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 Provide evidence of compliance with allowable specification, i.e. Harm Std, EAM, PMA No set format for documentation. Notified Body performs particular appraisal for equipment in Cats III & IV Decisions made concerning one material do not have to repeated PMA Taiex - Bratislava April 2005

12 Materials 5 Certification Materials must:
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 ) -{prepared by material manufacturer} Taiex - Bratislava April 2005

13 Materials 5 Certification
Material manufacturer’s certificate acceptable only if: Material Certification e.g. ISO 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 ) Guideline 7/5 Taiex - Bratislava April 2005

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

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