Overview

EN 10224:2002 - published by CEN - specifies the technical delivery conditions for non‑alloy steel tubes and fittings intended for the conveyance of aqueous liquids, including water for human consumption (potable water). The standard covers seamless and welded non‑alloy steel tubes, end preparation for butt welding, fittings fabricated from tube, and fittings fabricated from plate or strip. It applies to tube outside diameters from 26.9 mm to 2 743 mm and includes informative annexes on jointing, coatings/linings and size relationships.

Key topics and requirements

The standard concentrates on manufacturing, quality and documentation requirements needed for safe, durable piping used with aqueous media:

• Product scope: seamless and welded non‑alloy steel tubes; fittings from tube, plate or strip; butt‑weld end preparation.
• Size range: outside diameters from 26.9 mm to 2 743 mm.
• Manufacturing controls: steel and deoxidation processes, production methods for tubes and fittings.
• Chemical and mechanical requirements: specified limits for composition and mechanical properties (as applicable for non‑alloy steels).
• Dimensions and tolerances: dimensional requirements, tolerances for tubes and fittings, and relationship to nominal sizes (DN).
• End preparation: requirements for tube and fitting ends prepared for butt welding.
• Inspection & testing: mandatory inspection documents, sampling frequencies, mechanical tests, and non‑destructive testing (NDT) methods for seams and welds.
• Soundness and leak tightness: tests to verify hydraulic integrity.
• Marking and documentation: inspection certificates and marking requirements for traceability.
• Coatings and linings: guidance on commonly used protective systems and references to relevant coating/lining standards (informative).
• Jointing guidance: annexed guidance on other jointing methods (sleeve, flange, slip‑on, push‑fit) commonly used in aqueous piping systems.

Applications and practical value

EN 10224:2002 is intended for organizations that design, manufacture, specify or approve steel piping systems conveying aqueous liquids, including potable water. Typical applications include:

• Municipal water mains and distribution networks
• Industrial water systems, process water lines and cooling circuits
• Treatment plant piping and large‑diameter conveyance systems
• Fabrication of welded or seamless steel fittings used in potable and non‑potable water installations

Using EN 10224 helps ensure product uniformity, traceability, and compatibility with European procurement and construction practices. It also provides a baseline for specifying coatings/linings appropriate for corrosion protection in water service.

Who should use this standard

• Pipe and fitting manufacturers
• Specification writers and procurement engineers
• Water utility engineers and infrastructure owners
• Welding and NDT specialists
• Compliance and quality managers in construction and manufacturing

Related standards

EN 10224 references and aligns with other product, testing and NDT standards (for example EN 10020 series, EN 10246 series, EN 10204 inspection documents). Refer to the standard’s normative references and informative annexes for specific cross‑references when writing specifications or carrying out conformity assessment.
