How to cut thick wall seamless steel pipe?

1. There are two kinds of mechanical cutting: external installation and internal installation. The cutting and beveling of the pipe orifice are carried out by turning tool processing principle. The single machine has large span, large Machinable thickness, less waste, no pollution, no high temperature in the processing process, no impact on the pipe material, which is conducive to the welding. Water cutting processes pipeline by high pressure pump and carborundum. The cut is clean and the processing span is large, but its efficiency is low and the processing thickness is limited seriously.

2. In oxyacetylene flame cutting, by adjusting oxyacetylene valve and oxyacetylene valve, the mixing ratio of oxyacetylene and oxyacetylene can be changed to obtain three different kinds of flame: neutral flame, oxidation flame and carbonization flame.

3. Ion cutting, plasma cutting with different working gases can cut all kinds of metals that are difficult to cut with oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel); Its main advantage is that when cutting the metal with small thickness, the plasma cutting speed is fast, especially when cutting the ordinary carbon steel sheet, the speed can reach 5-6 times of that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and the heat affected zone is less.
