A carbon steel tee fitting is a three-way butt weld pipe fitting designed to connect three sections of piping and create a branch connection. It allows fluid flow to be distributed between the main pipeline and branch line while maintaining system strength and reliability.

Carbon steel tees are widely used because of their excellent mechanical strength, durability, and cost efficiency. They are suitable for general industrial piping systems where high strength and pressure resistance are required.

DTC supplies carbon steel butt weld tees manufactured according to ASME B16.9 standards, including equal tees and reducing tees. Our carbon steel tees are available in seamless and welded designs and are commonly used in oil & gas pipelines, petrochemical plants, water treatment systems, HVAC networks, and power generation facilities.
