，Three-way connectorTo the pipe department. Can be categorized by pipe diameter size. Generally made of carbon steel.Cast Steel，Stainless SteelThree-way hot forming involves flattening a pipe blank larger than the diameter of the three-way fitting to approximately the diameter of the fitting, then creating a hole at the point where the branch pipe is to be stretched; the pipe blank is heated before being placedMolding dieUnder pressure, the billet is radially compressed, during which the metal flows towards the branch pipe and forms the branch under the stretching action of the die. The entire process is shaped through the radial compression of the billet and the stretching of the branch section.
