Thick-walled
seamless steel pipe is a common type of thick-walled seamless steel tube. It is a special material of thick-walled steel pipe. For thick-walled seamless steel pipe, it is more important to protect the most basic use and play. More important performance. Thick-walled seamless steel pipe is an important material for seamless steel pipes. Its hardness is relatively large. Generally, it is difficult to master the cutting techniques and methods when cutting. In this way, thick-walled seamless steel pipes can be successfully cut. Can not hurt people. To safely cut thick-walled seamless steel tubes, the following operations are recommended.
1. Mechanical cutting.
Mechanical cutting adopts both external installation and internal installation. It uses the turning tool processing principle to cut off and bevel the nozzle. The single machine has a large span, can be processed with a large thickness, less waste, and has no pollution. The processing process does not generate high temperature. Does not affect the pipe material, which is conducive to welding. Water cutting uses high pressure pumps and corundum to process pipelines. The cuts are clean and the processing span is large, but its efficiency is low and the processing thickness is severely restricted.
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, oxidized flame and carbonized flame.
3. Ion cutting.
Plasma cutting with different working gases can cut a variety of oxygen cutting difficult-to-cut metals, especially for non-ferrous metals (
stainless steel, aluminum, copper, titanium, nickel); its main advantage is that it cuts metal with small thickness At the time, plasma cutting speed is fast, especially when cutting ordinary carbon steel sheet, the speed can reach 5 ~ 6 times of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is less heat affected zone.
