Copper elbow manufacturers, the use of copper elbows, generally produced on the automatic rolling and bending unit. The solid elbow billet is inspected and cleaned of surface defects, cut to the required length, centered on the end face of the perforation end of the elbow billet, and then sent to the heating furnace to be heated and pierced on the punching machine. When the perforation continues to rotate and advance at the same time, under the action of the roller and the plug, a cavity is gradually formed inside the elbow, which is called a hair elbow.
Then it is sent to the automatic rolling and bending machine to continue rolling. Finally, the whole wall thickness is uniformed by the equalizing machine, and the diameter is sizing by the sizing machine to meet the specification requirements. It is a more advanced method to produce hot-rolled seamless steel elbows using continuous rolling and bending units.
