The difference between hot simmering elbow and cold simmering elbow

The difference between hot simmering elbow and cold simmering elbow The process is as follows: After the straight pipe is cut, the induction loop is put on the part of the steel pipe to be bent through the bending machine, and the pipe head is clamped by the mechanical rotating arm, and the induction loop is passed into the induction loop to heat the steel pipe. When it rises to the plastic state, mechanical thrust is used at the rear end of the steel pipe to bend, and the bent steel pipe is quickly cooled with coolant, so that heating, advancing, bending, and cooling are carried out, and the pipe is continuously bent. Bend it out. Hot simmering elbows are mainly used for building arc steel structures, tunnel supports, car * curved beams, subway engineering, aluminum doors and windows, ceilings, cylindrical inner frames, balcony handrails, shower doors, production line tracks, fitness equipment, and other industries. The cold simmering elbow is a method of bending processing at room temperature without heating or without changing the material structure. It is called the cold simmering elbow. In order to prevent the pipe from collapsing or deforming during the bending process, some auxiliary materials or equipment, such as springs, are often filled in the pipe. Cold simmering elbows are generally used for small-diameter pipes, but large-diameter pipes cannot be cold-formed! The elbows are made of cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals, and plastics. The cold simmering elbow is bent using a complete set of bending molds, and is mainly used for oil, gas, liquid, etc.! Post time: Jun-22-2021
