Application of Square Duct Machine

Stainless steel square duct is a hollow strip of steel, because the section is square, so it is called square duct. A large number of pipelines are used to transport fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when bending and torsion strength are the same, the weight is lighter, so it is also widely used to manufacture mechanical parts and engineering structures.

Stainless steel square pipe is divided into two categories: seamless steel duct and welded steel duct. According to the section shape, it can be divided into square and rectangular ducts. Round ducts are widely used, but there are also some semi-circular, hexagonal, equilateral triangle, octagonal and other special-shaped ducts.

For stainless steel square pipes subjected to fluid pressure, hydraulic tests should be carried out to test their pressure resistance and quality. Under the prescribed pressure, no leakage, wetting or expansion will occur to qualify. Some steel ducts also need to carry out flanging test, flattening test, etc. according to standards or requirements of the demand side.

Therefore, the square tube machine for manufacturing square ducts is particularly important. The square duct machine is also called round duct to square duct machine, waste round duct to square duct machine, new scaffold 48 old round duct machine to 40 square duct machine and round duct machine to cold rolling machine. It is a new type of equipment for processing construction brackets. After recycling the waste construction pipe steel, it can be processed into square pipe by machine. The waste can be used to turn waste into treasure and square pipe can continue to be used in construction. The new type of formwork reinforcement and support system is exquisitely designed, replacing wood with steel, eliminating wood, facilitating disassembly, and replacing wood square with square tube. It has high strength and is not easy to deform, and fully protects construction accuracy and quality.
