The Use of Square Tube

The square tube is a steel tube with a hollow section and equal side lengths; it is a strip of steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.

Square tubes are classified by use: square tubes for decoration, square tubes for machine tools, square tubes for machinery industry, square tubes for chemical industry, square tubes for steel structures, square tubes for shipbuilding, square tubes for automobiles, square tubes for steel beams and columns , special purpose square tube.

What is the purpose of the square tube? What are the main applications?

1. Galvanized welded square tubes for low-pressure fluid transportation are mainly used to transport water, gas, air, oil and heating hot water or steam, and are limited to general low-pressure fluids;

2. Galvanized welded square tubes for low-pressure fluid transportation are mainly used to transport water, gas, air, oil and heating water or steam, generally low-pressure fluids, and the outside of the square tube is hot-dip galvanized or cold-galvanized anti-corrosion ;

3. Welded square tubes for mining fluid transportation are mainly used for mine pressure, drainage, and shaft discharge gas. Straight seam welded square tubes are used;

4. Large-diameter electric welded square tubes used for low-pressure fluid transportation, mainly used to transport water, sewage, gas, air, and low-pressure fluids such as heating steam;

5. The mechanical structure adopts stainless steel welded square tube, which is mainly used for the decoration of mechanical parts and structural parts such as machinery, vehicles, bicycles, furniture, hotels and restaurants;

6. Stainless steel welded square tube for fluid transmission, mainly used to transport low-pressure corrosive media;

7. Spiral square tubes for low-pressure transportation are mainly used for low-pressure water, oil, natural gas, heating and other pipelines;

8. Square tubes for transporting flammable and non-flammable liquids are mainly used for transporting flammable and non-flammable liquids of low-pressure or high-pressure square tubes, and the requirements are relatively high.
