Steel Weld-On Reductions

Steel weld-on reductions are designed to connect pipes with different diameters by welding, providing a strong, permanent and leak-tight connection. They are widely used in hydraulic, steam, oil, gas and industrial piping systems where high mechanical strength and reliable performance are required.

At the POLBERIS online store you will find steel weld-on reductions manufactured from high-quality carbon steel, offering excellent durability, pressure resistance and long service life in demanding industrial environments.

These products are also commonly known as weld reducers, butt weld reducers, BW reducers, concentric reducers, eccentric reducers, pipe reducers, welding reducers, reducing fittings and weld-on pipe fittings.

Steel weld-on reductions are widely used by welders, pipefitters, maintenance technicians, hydraulic engineers, mechanical contractors and industrial installers for connecting pipelines, pumps, valves, pressure vessels and process equipment in power plants, refineries, chemical plants, manufacturing facilities and general industrial installations.

Whether you need a standard butt weld reducer or a professional weld-on reduction fitting for industrial piping systems, POLBERIS offers a wide selection of reliable steel weld-on reductions designed for demanding industrial and engineering applications.
