What is the Difference Between Square Tube and Rectangular Tube?

Date:2019-08-08    keywords:rectangular tube,square tube,difference
1. The cross section is different: the cross section of the square tube is square; the cross section of the rectangular tube is rectangular.

2. different uses:
The use of square tubes: construction, machinery manufacturing, steel construction projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automotive chassis, airports, boiler construction, highway railings , building construction, pressure vessels, oil storage tanks, bridges, power station equipment.

The use of the rectangular tube: a large number of pipes used to transport fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts. And engineering structure. Also used to produce a variety of conventional weapons, barrels, shells and soon.

3. The scope of coverage is different: square tube is a kind of rectangular tube, included in the rectangular tube.

Extended information:
There are two main ways of producing rectangular tubes, namely, cold rolling and hot rolling. The rectangular tube hot rolling is made by rolling the hot rolled strip through a process. Cold drawn or cold rolled precision tube, cold rolled tube is a cold drawn or cold rolled precision tube for mechanical structure, hydraulic equipment with high dimensional accuracy and good surface finish.

Many defects in the square tube are caused in the perforation, so the perforation process in the tube blank is a key procedure for producing the square tube. The main difficulty of high alloy perforation lies in the low perforation performance. In order to ensure the quality, it is necessary to rationally select the deformation parameters of the perforation.
