Stainless Steel Tee Manufacturer

Product Introduction:

1. Hydraulic bulging

The hydraulic bulging of the tee is a forming process of compensating the bulging of branch pipe by the axial direction of metal material. The process is to use special hydraulic press, with 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 metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.

The head and shoulder wall thickness of the tee are increased.

Due to the large equipment tonnage required by the hydraulic bulging process of the seamless tee, it is mainly used in the manufacturing of the tee with standard wall thickness less than DN400 in China at present. The suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold hardening tendency, including some non-ferrous metal materials, such as copper, aluminum and titanium.

2. Hot pressing

Hot pressing is to flatten the pipe billet larger than the diameter of the tee to the diameter of the tee, and to open a hole in the part of the stretch branch pipe; The tube billet is heated, put into the forming die, and the punching die of the stretch branch pipe is loaded into the tube billet; Under the action of pressure, the tube billet is compressed radially. In the process of radial compression, the metal flows towards the branch tube and forms the branch tube under the stretching of the die. The whole process is formed by the radial compression of the tube billet and the stretching of the branch tube. Different from the hydraulic bulging tee, the metal of the hot pressing tee is compensated by the radial movement of the tube billet, so it is also called radial compensation process.

Due to the use of pressing tee after heating, the tonnage of equipment required for material forming is reduced. Hot pressing tee has wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials; Especially for large diameter and thick tube wall, this forming process is usually adopted.
