The EU Pressure Equipment Directive (PED 2014/68/EU) requires that pressure equipment placed on the EU market meets Essential Safety Requirements (ESRs) and carries a CE mark. duplex S31803 (EN 1.4462) pipe supplied to EU buyers for pressure equipment must include EN 10204 3.1 material test certificates, dimensional reports and, for Category III/IV equipment, notified body (NoBo) approval of the material's European Approval for Materials (EAM) or use of a listed material in a harmonised standard such as EN 13480-2 (metallic industrial piping).
| PED Category | Fluid Group | NoBo Involvement | Typical Equipment |
|---|---|---|---|
| I | Group 2 | None (manufacturer's declaration) | Low-risk utility lines |
| III | Group 1 | Module B + D or H | Process plant critical piping |
| IV | Group 1 | Module G or H1 | High-pressure reactor connections |
Ragnar Metals supplies PED-compliant pipe with EN 10204 3.1 certificates from an accredited inspection body. We support EU fabricators with full documentation packages including EN 10216-5 or EN 10217-7 compliance, lot traceability, and REACH/RoHS declarations. Lead time for PED documentation 5–7 working days.
Selecting the correct duplex grade depends on the chloride concentration, temperature, H2S partial pressure, and design pressure of your application. Duplex 2205 (S31803/S32205) offers a PREN of 34–35 and handles chloride concentrations up to 1,000 ppm at temperatures up to 150°C. Super Duplex 2507 (S32750) with PREN 42 handles up to 35,000 ppm chloride (seawater) at temperatures to 220°C. For H2S sour service, both grades comply with NACE MR0175/ISO 15156 when hardness is maintained below HRC 28 (max HRC 32 per ASTM A890). Ragnar Metals and Tubes supplies a complete range of duplex and super duplex products to ASTM, ASME, EN, and ISO standards with full EN 10204 3.1 MTC and third-party inspection by SGS, TUV, or Bureau Veritas.

|---|---|---|---|---|---|
| Duplex 2101 | S32101 | 26 | 200 | ASTM A240 | Mildly corrosive service, structural |
| Duplex 2205 | S31803/S32205 | 34–35 | 1,000 | ASTM A182 F51/F60 | General oil and gas, chemical process |
| Super Duplex 2507 | S32750 | 42 | 35,000 | ASTM A182 F53 | Seawater, deep offshore, sour service |
| Super Duplex Zeron 100 | S32760 | 40 | 35,000 | ASTM A182 F55 | Offshore umbilicals, sour service |
