Summary：Thick-walled seamless steel pipe is a common type of thick-walled seamless steel pipe. It is a special material of thick-walled steel pipe. For thick-walled seamless steel pipe, it is more important to protect the basic use and play more Important performance. Thick-walled seamless steel pipe is an important material of seamless steel pipe. Its hardness is relatively large. Generally, it is more difficult to master the cutting skills and methods when cutting, so that thick-walled seamless steel pipe can be successfully cut. Can not hurt people. In order to safely cut thick-walled seamless steel pipes, the following operations are recommended.
1. Mechanical cutting adopts two kinds of external installation and internal installation. It uses the turning tool processing principle to cut and bevel the nozzle. The single machine has a large span, large processing thickness, less waste, no pollution, and no high temperature during the processing. It does not affect the material of the pipe and is beneficial to the welding. Water cutting processes pipelines through the combined action of high-pressure pumps and emery. The cuts are 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, oxidizing flame and carbonized flame.
3. Ion cutting, plasma cutting and different working gases can cut all kinds of metals that are difficult to cut by oxygen, 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 small, the plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, 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.
