Features of stainless steel reducing tee: in the forming of reducing tee, the required shape and size can be achieved only after several times of deformation. The shape of the reducing tee is determined by the shape of the inner cavity of the forming die. Therefore, the shape of the die core is the main factor of the quality of the tee. The shape of the die core is directly related to the shape of the die core. The quality of the die core determines the forming quality of the tee. Therefore, it is very important to control the shape and size of the die core. The contour of the reducing tee is determined by the shape of the inner cavity of the forming die. Therefore, the dimensions of the shoulder of the tee, the shape of the transition part between the main pipe and the branch pipe, etc. reflect the content of the tee joint by the forming die. Therefore, the design, manufacture and maintenance of the tee die are important factors related to the quality of the tee joint. The hydraulic extrusion forming of reducing tee is a one-time forming process. The surface of the product is flat and smooth without concave and convex points. The wall thickness of the main pipe and branch pipe of the tee is uniform. For the forming process of reducing tee, it is very important to determine the process parameters of tee. If the pressure of tee extrusion is too high or too low, it will lead to poor forming, which will lead to repair or scrap. The current, voltage and speed of reducing tee in welding process will directly affect the welding quality. The pushing speed of hot push tee should be consistent with the heating speed heated to the specified temperature, otherwise, it will be damaged This may cause poor forming of tee. The reducing tee is a kind of pipe fitting which is used at the branch pipe of pipeline. There are two kinds of production processes, cold extrusion and hot pushing. Cold extrusion of tee is a kind of processing technology which extrudes the axial compensation of stainless steel material into branch pipe. The processing process is to use hydraulic press to put hydraulic oil into the blank with the same outer diameter as the stainless steel tee, and the two oil steels of the hydraulic press move synchronously to the middle to extrude the reducing tee blank. The volume of the blank becomes smaller after extrusion, and the pressure force of the hydraulic oil in the blank increases with the decrease of the blank volume. When the required force is reached, the tee branch pipe is extruded.
