What are the cutting methods of thick-walled spiral steel pipes

Spiral steel pipe cutting methods with various types. To be easier to method to cut the spiral steel pipe. We list three methods. Wish these will help you.

1. Mechanical cutting adopts external installation and internal installation. It adopts the principle of turning a tool to cut and bevel the nozzle. The single machine has a large span, can process a large thickness, less waste, no pollution, and does not generate high temperature during processing. It does not affect the pipe material, which is conducive to welding. Water cutting processes the pipeline through the combined action of a high-pressure pump and emery. The incision is clean and the processing span is large, but its efficiency is low and the processing thickness is severely limited.

2. Oxygen acetylene flame cutting, by adjusting the oxygen valve and acetylene valve, the mixing ratio of oxygen and acetylene can be changed to obtain three different flames: neutral flame, oxidation flame, and carbonization flame.

3. Ion cutting, plasma cutting with different working gases can cut various metals that are difficult to cut by oxygen cutting, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel), the cutting effect is better; its main advantage is the cutting thickness When the metal is not large, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5~6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and the heat-affected zone is less.
