[0002] Seamless steel pipe is a steel pipe made by perforating a whole round steel with no welds on its surface. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe and jacking pipe and other types. From the cross-sectional shape, seamless steel pipe is divided into round and special-shaped types. Special-shaped pipes include square, oval, triangular, hexagonal and other complex shapes.

[0003] Mechanical equipment is used to cut seamless steel pipes. Common methods include sawing and grinding wheel cutting.
