Seamless steel tube, cut off the main pipe cutting machine cutting, machine cutting, flame cutting, sawing, etc. Characteristics of pipe cutting equipment as described below.
(1) pipe-cutting machine
Pipe cutting machine simple, less investment, widely, some still have Groove features and automatic loading and unloading and aggregate device. Seamless thick-walled steel pipe cutting machine is commonly used on the finishing line devices.
(2) pipe cutting saw
Can be classified as pipe saws, band saws and circular saws and other forms. Pipe saw more than 1 row cut seamless thick walled steel tubes, high production efficiency, but the complex structure, high investment; the band saw and circular saw lower production efficiency, smaller investments. Circular saw used to cut off small outer diameter thick wall seamless steel pipe, band saws for cutting larger diameter seamless thick walled steel tubes.
(3) the flame cutting
Hydrogen-oxygen-flame cutting, including cutting, oxygen cutting and plasma cutting, the cut method is suitable for the diameter large, Guan Bite seamless thick walled steel pipe cutting. Plasma cutting, cutting speed is faster. Because of the high temperature causes flame cutting, incision exist near the surface of the heat affected zone and port is not very smooth.
(4) machine tool cutting
The efficiency of this cut is very low, generally used for sampling and sample preparation, and so on.
