Information

What is a stainless steel welding tee?

Welding Tee 4'' × 3'' SCH10S 304L ASTM A403 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.

Welding 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 welding tees are available in both seamless and welded versions and are manufactured according to internationally recognized standards including ASTM, EN, ANSI, DIN, and others.
