Product introduction

Stainless steel tee for pipe fittings, pipe connectors. Used in the main pipe to branch pipe. The stainless steel tee has equal diameter and reducing diameter, and the nozzle end of the equal diameter tee is the same size; The main pipe size of the reducing tee is the same, and the nozzle size of the branch pipe is smaller than that of the main pipe.

Stainless steel tee is a pipe fitting for pipe branches. For the use of seamless pipe manufacturing tee, the process is usually used hydraulic expansion and hot forming two kinds. Hydraulic expansion of stainless steel tee is a forming process in which branch pipe is expanded by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee. Through the two horizontal side cylinders of the hydraulic press, the tube blank is extruded synchronously. The volume of the tube blank becomes smaller after being extruded, and the liquid in the tube blank increases with the volume of the tube blank. The metal material flows along the inner cavity of the die under the double action of the liquid pressure in the side cylinder and the tube blank and expands the branch pipe.
