EN 10253-2 covers the technical delivery requirements for seamless and welded butt weld fittings made of non-alloy and alloy steels for use in pressure piping and pressure vessels at room temperature, elevated, or low temperatures. These fittings are designed for butt welding to pipes and flanges according to relevant EN and ISO standards.
EN 10253-2 Butt weld fittings standard is one of the standards developed by the European Committee for Standardization (CEN). It specifies the dimensions, materials and other relevant requirements for seamless and welded steel pipes and fittings, especially for seamless and welded steel pipes and fittings used for pressure applications.
It specifies: type of fittings ;
type A : Butt-welding fittings with reduced pressure factor ;
type B : Butt-welding fittings for use at full service pressure ;
