What is the molding process of stainless steel tee?
There are two mold process of stainless steel tee,which are hydraulic bulging,hot press forming.(Forming process of stainless steel tee)
Hydraulic bulging of stainless steel tee
The hydraulic bulging of the stainless steel tee is a forming process for expanding the branch pipe by axial compensation of the metal material. The process uses a special hydraulic machine to inject a liquid into the tube blank equal to the diameter of the stainless steel tee, and the liquid in the tube blank becomes smaller as the volume of the tube blank becomes smaller and the pressure rises.
The special hydraulic machine is used to inject liquid into the tube blank with the same diameter of the stainless steel tee, and the tube blank is synchronously centered by the two horizontal side cylinders of the hydraulic machine, and the volume of the tube blank becomes smaller after being squeezed, and the liquid in the tube blank is The volume of the tube blank becomes smaller and the pressure rises. When the pressure required for the expansion of the stainless steel three-way branch pipe is reached, the metal material flows along the cavity of the mold under the double action of the liquid pressure in the side cylinder and the tube blank to expand the branch pipe.
Due to the relatively large tonnage of equipment required for the hydraulic expansion process, it is mainly used in the manufacture of standard wall thickness stainless steel tees smaller than DN400. The suitable forming materials are low carbon steel and low alloy steel with relatively low cold work hardening tendency. ,stainless steel.
ASME B16.9 ASTM A403 WP304L reducing tees
Hot press forming of stainless steel tee
The stainless steel three-way hot press forming is to reduce the diameter of the stainless steel tee by a diameter of about three to the diameter of the stainless steel tee, and to open a hole in the portion of the tension branch; the tube blank is heated and placed in the forming mold, and A die of a tensile branch pipe is placed in the tube blank; the tube blank is radially compressed under the action of pressure, and the metal flows toward the branch pipe during the radial compression and forms a branch pipe under the drawing of the die. The entire process is formed by the radial compression of the tube blank and the stretching process of the branch portion. Different from the hydraulic bulging stainless steel tee, the metal of the hot-pressed stainless steel three-way branch pipe is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.
Due to the use of heated stainless steel tees, the tonnage required for material forming is reduced. The hot-pressed stainless steel tee has wide adaptability to materials, and is suitable for materials of low carbon steel, alloy steel and stainless steel; especially stainless steel tees with large diameter and thick wall,which is usually used.
