WHAT ARE THE MAIN CUTTING METHODS FOR RECTANGULAR TUBES?

The first of five techniques for cutting rectangular tubes is presented here:

（1） Pipe cutting machine

The pipe cutting machine is extensively used, requires minimal capital, and has basic equipment. A few of them can also serve as aggregate devices, load and unload automatically, and chamfer. A frequent piece of equipment in square and rectangular pipe finishing manufacturing lines is the pipe cutting machine;

（2）Saw blade

It is separated into three categories: circular, band, and pipe saws. While band saws and circular saws have low production power and minimal investment, pipe saws can cut several square tubes in rows at once and have a large output power, but their equipment structure is chaotic. Cutting smaller outer diameter rectangular tubes with a circular saw is appropriate, whilst cutting bigger outer diameter rectangular tubes with a band saw is appropriate;

（3） Sawing machine

The sawing machine is characterized by neat cutting and convenient welding during construction. The defect is that the power is too low, that is, too slow;

（4） Machine tool blocking

The plugging power is very low, and it is generally used for square tube sampling and sample preparation;

（5） Flame blockage

Plasma, hydrogen, and oxygen cutting are all included in flame cutting. Cutting seamless steel pipes with extra-large pipe diameters and substantial wall thicknesses is better suited for this cutting technique. Cutting using plasma has a rapid cutting speed. The square tube end surface is not smooth and there is a heat-affected zone close to the cutting due to the high temperature during flame cutting.

Square-shaped pipes come in both square and rectangular shapes. Round and square pipes may be made from a variety of materials. They are employed wherever and for whatever reason. Largely structural, ornamental, and architectural steel pipes make up the majority of square and rectangular pipes.

Steel pipe with equal side lengths is referred to as square pipe. After processing, strip steel is used to roll it. Strip steel is typically unloaded, leveled, curled, rolled into a square pipe, welded to produce a circular pipe, and then cut to the desired length. 50 pieces per packet, on average.
