Butt Weld Tee

Steel Pipe Tee for Industrial Piping Systems

Overview

Butt Weld Tee is a pipe fitting used to connect three sections of pipe and allow flow distribution or combination within a pipeline system.
It is welded directly to the pipe ends, providing a strong, leak-proof, and permanent connection suitable for high-pressure and high-temperature applications.

Butt weld tees are widely used in oil & gas, petrochemical, power generation, shipbuilding, offshore platforms, and industrial piping systems.

Product Features

  • Strong and permanent butt welded connection
