How to preventing coating damage during welding carbon steel pipe

Keywords:welding carbon steel pipe, coating
Carbon steel pipes are made of steel ingots or solid round steel through perforation, and then made by hot rolling, cold rolling or cold drawing. When longer carbon steel pipes are needed, due to the insufficient length of carbon steel pipes, then Two carbon steel pipes need to be welded together for use.

At present, when welding carbon steel pipes, because the carbon steel pipes are coated with anti-corrosion coatings, high temperatures are easily generated at the weld joints during welding, which easily causes the anti-corrosion coatings in the carbon steel pipes to burn out during welding.

A carbon steel pipe for preventing coating damage during welding, including carbon steel pipes. The inner wall of the carbon steel pipes is coated with anti-corrosion paint. One end of the carbon steel pipe is fitted with a white steel pipe. There is a through hole, and a blower is fixed at the center of the other side of the carbon steel pipe. The carbon steel pipe is equipped with a movable movable plate. The movable plate is equipped with a cooling device to prevent the anti-corrosion coating from burning out during welding. The cooling device includes the front and rear sides of the movable plate. The fixed block is fixed with a spray nozzle for cooling, and a water tank is fixed in the fixed block. A piston that can move the spray nozzle is arranged in the water tank. The water in the water tank evaporates and drives the piston to move when heated.
