Reducing Butt Weld Tee
Our seamless reducing butt weld tee is hot extruded three-way pipe fitting with a smaller branch outlet for pipeline flow split of different diameters. Strictly manufactured following ASME B16.9 & Indian IS 1239 standards, all sizes maintain full nominal dimension without minus tolerance, widely used in petroleum, chemical, power and water treatment piping systems.
Overview
Reducing Butt Weld Tee is an integral seamless hot extruded butt-weld pipe fitting, also known as unequal tee. Its straight run matches main pipe diameter, while the lateral branch adopts smaller size to realize shunt or confluence of different-diameter pipelines.
Integral seamless extrusion forming ensures uniform wall thickness and outstanding pressure bearing performance. Raw materials cover carbon steel A234 WPB and stainless steel A403 WP304 / WP316L. We strictly inspect OD, ID and wall thickness of every tee, guarantee zero minus tolerance without thin-wall cost cutting. Complete inch & metric size range, all custom reducing ratios available to match diverse pipeline designs.
