1. The mechanical cutting of thick-walled spiral steel pipe adopts two types of external installation and internal installation. It uses the principle of turning tool processing to cut and groove the nozzle. The single machine has a large span, a large thickness that can be processed, less waste, and no pollution. It does not generate high temperatures, does not affect the pipe material, and is conducive to welding. Water cutting processes pipes through the joint action of high-pressure pumps and corundum. 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 thick-walled spiral steel pipe, 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, oxidizing flame, and carbonizing flame.
3. Ion cutting thick-walled spiral steel pipe, plasma cutting with different working gases can cut all kinds of metals that are difficult to cut by oxygen cutting, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel) cutting effect is better; its main The advantage is that when cutting metal with small thickness, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheet, 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 is less area of influence.
