BS EN 10253-1:2026 Butt-welding pipe fittings Part 1: Wrought carbon steel for general use and without specific inspection requirements

This British Standard specifies delivery requirements for seamless and welded carbon steel butt-welding fittings without specific inspection requirements.

BS EN 10253-1:2026 specifies the technical delivery requirements for seamless and welded butt-welding fittings made of wrought carbon steel for general use without specific inspection requirements. It covers elbows, return bends, concentric and eccentric reducers, equal and reducing tees, and caps. The standard defines steel grades and chemical composition, mechanical properties, weldability, dimensions and tolerances, manufacturing and heat treatment, inspection and testing, inspection documents, marking, protection, and packaging. It supersedes BS EN 10253-1:1999 and implements EN 10253-1:2026 in the United Kingdom.

Application Scope: Suitable for manufacturers, suppliers, inspectors, engineers, and purchasers of carbon steel butt-welding pipe fittings for general industrial applications that are not covered by the European Pressure Equipment legislation.
