Information

What is a stainless steel reducing tee?

Reducing Tee 4'' × 3'' SCH10S ASTM A403 316L B16.9 is a butt weld reducing pipe fitting designed to create a branch connection between pipes of different diameters. It is widely used in industrial piping systems to divide or redirect the flow of liquids and gases while maintaining smooth flow characteristics.

Reducing tees are commonly installed in:

• Water supply systems
• District heating systems
• Central heating installations
• Oil and gas pipelines
• Industrial process piping

How is a butt weld tee installed?

The fitting is butt welded directly to the pipeline. For proper installation, the pipe diameter and wall thickness should match the tee dimensions. Before welding, all pipe ends should be thoroughly cleaned and properly prepared to ensure a high-quality welded joint.

Stainless steel reducing tees are available in both seamless and welded versions and are manufactured according to internationally recognized standards including ASME B16.9, ASTM A403, EN, ANSI, and DIN.

316 / 316L Stainless Steel

316 / 316L stainless steel is a highly corrosion-resistant austenitic stainless steel with excellent weldability and formability. Originally developed for the paper industry, it provides superior resistance to sulphur compounds, aggressive chemicals, seawater, and elevated temperatures.

Equivalent grades: DIN 1.4401, 1.4404, SS316, AISI316, AISI316L, SS316L.
