The tri-fitting hot forming process involves flattening a tube blank larger than the tri-fitting diameter to approximately the size of the tri-fitting diameter, then creating a hole at the location of the extension branch. The tube blank is heated and placed into the forming mold.Through the two horizontal side cylinders of the hydraulic pressAfter being compressed, the volume decreases, and the liquid inside the billet increases in pressure as the billet's volume decreases. When it reaches the pressure required for the branch of the tee to expand.Metal materials on the sideVessel and billet interiorsUnder the double action of liquid pressure, it flows along the mold cavity and expands out through the branch pipe.
