PED 2014/68/EU Compliance: What Fittings Buyers Must Verify

Why this matters

If your equipment will be put into service inside the European Economic Area, PED 2014/68/EU (the Pressure Equipment Directive) is not optional. It applies to stationary pressure equipment with a maximum allowable pressure (PS) above 0.5 bar gauge, and that includes pipes, fittings, flanges, expansion joints and many other components a procurement engineer buys every day. Getting CE marking wrong is a market-access issue, not just a paperwork issue.

Scope comparison

Key compliance points

• Category I: manufacturer's internal production control (Module A); no notified body needed.
• Category II: requires Modules such as A2, D1 or E1 with notified body involvement on surveillance.
• Categories III and IV: full notified body involvement, typically Module B (EU-type or design examination) combined with C2, D, E, F or H/H1 for production.
• Materials: Pressure-bearing materials must either come from a harmonised standard, a European Approval for Materials (EAM), or a Particular Material Appraisal (PMA) made by the manufacturer and accepted by the notified body.
• MTR per EN 10204: typically 3.1 for Category I and II, 3.2 for higher categories or where the notified body or buyer requires it.
• CE marking: required for items in Category I and above. Sound Engineering Practice (SEP) items in the scope but below category boundaries do NOT receive CE marking.

When PED applies to your fittings order

• Carbon steel butt-welding fittings on a refinery line: typically Group 2 fluid; category depends on DN and PS. A NPS 12 line at PS 50 bar is usually Category II at minimum.
• Hydrogen, ammonia or LPG service: Group 1, hazard category climbs quickly.
• Steam piping: special PED rules apply because steam is treated separately.
• SEP items: very small or low-pressure items may fall outside CE marking, but the manufacturer must still build them to good engineering practice.

We supply CE-marked seamless butt-welding pipe fittings, forged flanges and seamless steel pipes for PED-scope projects, with notified body surveillance where required.

Procurement / spec checklist

1. State PS, design temperature, fluid group and state (gas/liquid) for every item.
2. Calculate the PED category from the relevant PED Annex II chart and state it in the inquiry.
3. Specify the conformity assessment module the supplier must follow.
4. Require EN 10204 3.1 or 3.2 MTRs and notified body identification where applicable.
5. Require the manufacturer to issue an EU Declaration of Conformity referencing the directive and applicable harmonised standards (e.g. EN 1092-1, EN 10253-2 / 10253-4 for fittings, EN 10216 for seamless pipe).
6. Verify the CE marking and notified body number are stamped on the body where space permits.
7. Reference the latest published guidelines for the directive.
