Seamless steel pipe cutting the main way to cut off the machine, machine cutting, flame cutting, sawing and so on.
(1) Pipe cutting machine
Pipe cutting machine equipment is simple, less investment, the application of a wide range, and some also has a groove function and automatic loading and unloading materials and aggregate devices. Pipe cutting machine is a commonly used equipment for seamless steel pipe finishing line.
(2) Pipe saws
Can be divided into row pipe saw, band saw and circular saw several forms. Pipeline saws can be cut into multiple rows of steel pipe, high production efficiency, but the equipment structure is complex, high investment; band saw and circular saw production efficiency is low, less investment. The circular saw is suitable for cutting off steel pipes with smaller outer diameters, while band saws are used to cut off steel pipes with larger outer diameters.
(3) Flame cut off
Flame cut off, including oxygen cutting, hydrogen and oxygen cutting and plasma cutting, the cutting method is more suitable for large diameter, thick wall seamless steel pipe cutting. When the plasma is cut, the cutting speed is faster. Due to the high temperature of the flame cutting, there is a heat affected zone near the incision and the port surface is not smooth.
(4) Machine cut off
This cut off the efficiency is very low, generally used for sampling and sample preparation.
