Steel threaded pipe fittings

This European standard specifies requirements for threaded fittings of nominal sizes from DN 6 to DN 150 inclusive, made out of welded or seamless steel tubes, forging and rolled bars. It is applicable to those threaded steel pipe fittings that are used in the transportation and distribution of liquid or gas.

Stahlfittings mit Gewinde

Diese Norm legt Anforderungen fest für Gewindefittings mit Nennweiten DN 6 bis einschließlich DN 150, aus geschweißten oder nahtlosen Rohren, Schmiedestücken und gewalzten Stäben. Sie gilt für solche Stahlfittings mit Gewinde, die für den Transport von Flüssigkeiten und Gas verwendet werden.

Raccords filetés en acier

La présente norme européenne définit les prescriptions relatives aux raccords filetés de dimensions nominales allant du DN 6 au DN 150 inclus, fabriquées à partir de tubes en acier soudés ou sans soudure, de pièces forgées et de barres laminées. Elle est applicable aux raccords filetés en acier qui sont utilisés pour le transport et la distribution de liquide ou de gaz.

Overview

EN 10241:2000 is a CEN European standard that specifies requirements for steel threaded pipe fittings used in the transportation and distribution of liquids and gases. The standard applies to threaded fittings of nominal sizes DN 6 to DN 150 made from welded or seamless steel tubes, forgings and rolled bars. EN 10241 defines the baseline technical and quality expectations for manufacturers, specifiers and users of threaded steel fittings across industrial and utility piping systems.

Key Topics

The standard covers essential technical and quality aspects relevant to threaded steel fittings, including:

• Scope and applicability for threaded fittings in nominal sizes DN 6–DN 150 for liquid and gas service
• Material types accepted (welded or seamless tubing, forgings, rolled bars) and expectations for material suitability
• Manufacturing requirements and accepted production forms for threaded components
• Dimensional and tolerance requirements for threaded connections and mating surfaces
• Inspection and testing provisions to ensure mechanical integrity and leak-tight performance
• Marking, documentation and traceability to identify product origin and conformity
• Quality assurance and conformance criteria required for supply and installation

(EN 10241 sets the framework for these topics; for exact test methods, dimensional tables and acceptance criteria refer to the published standard text.)

Applications

EN 10241 is intended for stakeholders involved in the specification, manufacture, procurement and installation of threaded steel pipe fittings, including:

• Mechanical and piping engineers specifying fittings for process, utility and building services
• Manufacturers and fabricators producing threaded fittings from steel tubing, forgings or bars
• Purchasers and procurement teams in oil & gas, water distribution, HVAC and industrial process sectors
• Inspection and quality control personnel verifying conformity to European requirements

Common practical uses include distribution pipelines, branch connections, repair work, instrumentation hookups and small-bore piping where threaded connections remain appropriate.

Related Standards

EN 10241 complements other European standards that address steel pipes, non-threaded fittings, flanges and pressure equipment. Users should coordinate EN 10241 requirements with project-specific piping standards, national regulations and applicable pressure- or material-specific standards when selecting and qualifying fittings.
