[0002] Tee is also called pipe tee or tee pipe fitting, tee joint, etc. It is mainly used to change the direction of the fluid and is used at the branch pipe of the main pipeline. It can be classified according to the size of the pipe diameter. It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon asphalt, PVC and other materials. The drawn tee is manufactured by processing the steel pipe so that it has three outlets and can connect three pipelines. The characteristic of this manufacturing method is that the deformation ability of metal molecules is used in the manufacturing process to upgrade and strengthen the interior of the pipeline while maintaining its appearance. Therefore, the strength of the drawn tee connection is higher than that of the conventional pipeline connection, and it can better withstand the pressure and external force of fluids such as water and oil.

[0003] Most of the existing drawn multi-button tee pipes are fixedly connected to other pipelines by flanges and are all provided with length compensation devices, which makes the connection more troublesome when there is a gap at the connection position between the tee pipe and other pipelines; therefore, the market urgently needs to develop a drawn multi-port tee pipe to help people solve the existing problem.
