Hydraulic bulging process of tee

Tee is a common pipe fitting, mainly used to change the direction of the fluid, used in the main pipeline to branch pipe. Our company mainly produces three materials including: carbon steel, stainless steel, alloy steel. There are several kinds of forming process of tee, let us briefly introduce the forming process of hydraulic expansion tee.

The hydraulic bulging of the tee is a forming process in which the branch pipe is bulged by the axial compensation of the metal material. Hydraulic bulge forming tee needs special hydraulic press, with the three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and pressure, when pressure tee branch pipe bulge out to the side of metal materials in liquid pressure in the cylinder and the pipe under the dual role of flow along the mold cavity and the branch pipe.

The tee hydraulic bulging process can be formed at one time, and the production efficiency is high. The wall thickness of the head and shoulder of the tee was increased. Because of the large tonnage of equipment required by the hydraulic bulging process of seamless tee, it is mainly used in the manufacture of standard wall thickness tee less than DN400 in China. The suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low tendency of cold hardening.

Haihao Group has been supplying tees of various materials and sizes for nearly 40 years. Whether it is equal tee or reducing tee, it has received positive feedback from new and old customers. We have mastered the forming process skills of the hydraulic tee, and have provided numerous quality and quantity guaranteed tee for customers.
