Buttweld Equal Tee
- It connects pipes of the same diameter.
- The branch direction of the pipe is perpendicular to the main pipe.
- The wall thickness range is SCH5S-XXS. For seamless tee fittings, the size range is 1/2”–24” (DN15–DN600), and for welded tee fittings, the size range is 1/2”–48” (DN15–DN1200).
- It is made of carbon steel, stainless steel, duplex steel, or special alloy steel.
Production Description
What Is a Buttweld Equal Tee?
A Buttweld Equal Tee is a type of pipe fitting used to divide or combine fluid flow in industrial piping systems. All three outlets of an equal tee have the same diameter, ensuring smooth and balanced flow distribution. This fitting is widely used in industries such as oil & gas, petrochemical, power generation, shipbuilding, water treatment, and mechanical engineering.
If your project requires precise flow management, durability, and secure welded connections, a buttweld equal tee is the ideal solution.
Buttweld equal tee fittings have the same diameter in all three ports, whereas reducing tees often have two branches with the same diameter and one branch with a different diameter.

Note: Seamless steel pipes can be processed into seamless pipe fittings, which do not require welding and have no welds. They have better sealing and pressure resistance, and are suitable for high-pressure, high-temperature, or systems with higher sealing requirements.
Generally, fittings made from steel plates are welded fittings, which are formed by joining and welding the edges of the steel plates. During the welding process, a weld seam is formed at the joint. This manufacturing process is relatively simple and suitable for general low-pressure piping systems.
