What are the cutting methods of spiral steel custom pipeline

　　At present, the common pipe cutting method of spiral steel custom pipeline manufacturers is plasma cutting. When cutting, there will be a lot of metal vapor, ozone, nitrogen oxide smoke and dust, which will seriously pollute the surrounding environment. The main way to deal with the problem of dust is how to inhale all the plasma dust into the dust removal equipment, so as to prevent air pollution.

　　As for the plasma cutting of spiral steel custom pipeline, the difficulty of dust removal is that the air is blown out to two opposite targets at the same time when the nozzle of plasma gun is cutting, so that the smoke and dust will come out from both ends of the ASTM A106 28 Inch SSAW Spiral Steel Custom Pipeline, and it is difficult to recover the smoke and dust well when it is installed at the suction port of one target of the spiral steel custom pipeline.

　　Therefore, the design principle of the dust collector cover is: 1. The air volume inhaled by the dust collector shall be greater than the total amount of smoke and dust produced by plasma cutting and the air inside the spiral steel custom pipeline, which shall cause a certain amount of negative pressure cavity inside the spiral steel custom pipeline, and the dust can be effectively sucked into the dust collector even though a large amount of outside air is not allowed to enter the spiral steel custom pipeline. 2. Suction inlet form and installation position. Make sure that the suction inlet absorbs more smoke and dust inside the spiral steel custom pipeline into the pipe to achieve the effect. Add a baffle at the position after the plasma gun cutting point to retain the smoke and dust inside the spiral steel custom pipeline. After a period of buffer, it may be as well to completely suction and clean it.

　　Install the smoke damper on the traveling car inside the spiral steel custom pipeline and place it at the plasma gun cutting point up to 500mm. After the spiral steel custom pipeline is cut, linger for a while to absorb all the smoke. Pay attention to the position of smoke damper after cutting. In order to keep the traveling car and steel pipe rotating in accordance with each other, the traveling wheel angle and inner roll angle of the traveling car must be maintained in the same way.
