Welded stainless steel tubes for the conveyance of aqueous liquids including water for human consumption - Technical delivery conditions
This European Standard specifies the technical delivery conditions for light gauge welded stainless steel tubes, primarily for water application, including water intended for human consumption, supplied in straight lengths and suitable for connection by adhesive bonding, capillary fittings, compression fittings, press fittings or by inert gas welding. The standard covers the size range from 6 mm to 159 mm outside diameter in two grades of stainless steel from EN 10088-2.
Geschweißte Rohre aus nichtrostenden Stählen für den Transport wässriger Flüssigkeiten einschließlich Trinkwasser - Technische Lieferbedingungen
Diese Europäische Norm legt die technischen Lieferbedingungen für geschweißte dünnwandige Stahlrohre aus nichtrostendem Stahl fest; die vorzugsweise für Wasser, einschließlich von Trinkwasser verwendet werden. Diese Rohre werden in geraden Längen geliefert, mit Eignung zum Verbinden durch Kleben, Kapillarfittings, Druckfittings, Preßfittings oder durch Inertgasschweißen. Die Norm deckt den Außendurchmesserbereich von 6 mm bis 267 mm ab. Zwei Stahlsorten aus EN 10088-2 sind festgelegt.
Tubes soudés en acier inoxydable pour le transport des liquides aqueux, y compris l'eau destinée a la consommation humaine - Conditions techniques de livraison
La présente Norme européenne spécifie les conditions techniques de livraison de tubes en acier inoxydable soudés de faible épaisseur, utilisés principalement pour le transport de l'eau, y compris l'eau destinée à la consommation humaine, fournis en longueurs droites et appropriés pour une utilisation avec des raccords à compression ou des raccords par emmanchement ou pour un raccordement par collage, brasage à l'argent ou soudage sous gaz inerte de raccords capillaires. La norme est applicable à la gamme de diamètres extérieurs compris entre 6 mm et 267 mm, pour des nuances d'acier inoxydable de l'EN 10088-2 (à l'exception des aciers martensitiques et à durcissement par précipitation).

Overview
EN 10312:2002 - "Welded stainless steel tubes for the conveyance of aqueous liquids including water for human consumption - Technical delivery conditions" - specifies technical delivery conditions for light‑gauge, longitudinally welded stainless steel tubes intended primarily for water and other aqueous liquids. The standard covers tubes supplied in straight lengths and suitable for connection by adhesive bonding, capillary fittings, compression fittings, press fittings or inert gas welding. It applies to tubes in the size range 6 mm to 159 mm outside diameter and uses stainless steel grades referenced from EN 10088-2.
Key topics and requirements
- Scope and designation
- Defines tube series, dimensions (OD and wall thickness), and steel designation format (EN 10312 + EN 10088-2 grade).
- Manufacturing
- Made from steel strip and longitudinally welded without filler material; supplied normally in the as‑welded condition unless solution‑annealed/annealed is specified.
- Purchaser information
- Mandatory order data: quantity (length or number), tube series, dimensions, steel grade, and standard length (5 m or 6 m).
- Several optional specifications (e.g., annealed/solution‑annealed condition, intergranular corrosion test, removal of internal weld bead, special inspection, different lengths, marking and end protection).
- Testing & inspection
- Includes mechanical and safety tests such as tensile test, flattening test, drift expanding test, leak‑tightness testing and non‑destructive testing (eddy current or ultrasonic) of weld seams.
- Corrosion resistance assessments including intergranular corrosion tests are available as options.
- Marking & packaging
- Requirements for marking (on tube or label) and packaging to protect ends and wound bundles.
Note: EN 10312 mentions preferred steel grades and flags a possible patent claim for a specific grade (1.4362); users should check licensing and national regulations when selecting materials.
Applications
- Potable water distribution and sanitary plumbing in buildings
- Domestic and commercial water supply lines
- HVAC and building services where corrosion resistance and potable‑water compatibility are required
- Systems using compression, press or capillary fittings, adhesive joints or TIG/inert gas welding
Who uses this standard
- Tube manufacturers and mill quality managers
- Architects, MEP engineers and specifiers for potable water systems
- Plumbing contractors and installers using press or compression fittings
- Procurement teams, conformity assessors and testing laboratories
