The mam methods of steel pipe cutting are pipe cutting machine cutting, machine cutting, flame-cutting, sawing, and so on. The characteristics of the pipe cutting equipment are as follows.
(1)Pipe cutting machine
The pipe cutting machine has simple equipment, less investment, and Is widely used. Some also have the function of inverting grooves and automatic loading and unloading and collecting devices. Pipe cutting machine is a commonly used equipment on a seamless steel pipe finishing line.
(2)Pipe cutting saw
It can be divided into several forms such as pipe saws, band to see, and circular saws. The pipe saw can cut multiple steel pipes in a row at a time, and the production efficiency is high, but the equipment structure is complicated and the investment is high； the production efficiency of band saws and circular saws is low, and the investment is small. Circular saws are suitable for cutting steel pipes with smaller outer diameters, while band saws are used for cutting steel pipes with larger outer diameters.
(3)Flame cut off
Flame cutting includes oxygen cutting, oxyhydrogen cutting, and plasma cutting. This cut method is more suitable for cutting seamless steel pipes with extremely large pipe diameters and thick walls. When plasma cutting, the cutting speed is faster. Due to the high temperature during flame cutting, there is a heat-affected zone near the incision and the port surface is not very smooth.
(4) Cutting off the machine tool
This cutting efficiency is very low, and it is generally used for sampling and sample preparation.
