EN 10253-2 Butt Welding Tee Equal Reducing

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 ;

EN 10253-2 tees are designed to branch a pipeline flow or change its direction while maintaining uniform strength. They are widely used in industries such as oil & gas, chemical processing, power generation, and water treatment systems.

We are a trusted manufacturer and exporter of EN 10253-2 Butt Weld Tees, providing high-quality seamless and welded pipe fittings for pressure piping and pressure vessel applications. Our tees are produced according to EN 10253-2, ensuring precise dimensions, corrosion resistance, and long service life in high-pressure and high-temperature environments.
