Square steel pipe 40*40mm structure uses engineering, etc
Square steel pipe 40*40mm is a name for square pipe, that is, steel pipe with equal length on both sides. It is made of strip steel after processing and rolling. Generally, the strip is unpacked, leveled, crimped and welded into a round tube, which is rolled into a square tube and then cut into the required length.
Main Uses
1. Galvanized welded square steel pipe 40*40mm for low pressure fluid transportation is mainly used for conveying water, gas, air, oil and heating hot water or steam. The use is limited to general low pressure fluid.
2, galvanized welded square steel pipe 40*40mm for low pressure fluid transport, mainly used for conveying water, gas, air, oil and heated water or steam, generally low pressure fluid, square pipe is hot dip galvanized or cold galvanized anticorrosion process.
3, mining liquid transport welding square steel pipe 40*40mm, mainly used for mine pressure, drainage, shaft exhaust gas using straight seam welding square pipe.
4, large diameter welding square steel pipe 40*40mm for low pressure fluid transmission, mainly used for conveying water, sewage, gas, air, low pressure fluid such as heating steam.
5, the mechanical structure adopts stainless steel welded square tube, mainly used for machinery, vehicle, bicycle, furniture, hotel and restaurant and other mechanical parts and structural decoration.
6, stainless steel welding for fluid transmission of square pipe, mainly used for conveying low pressure corrosive medium.
7, spiral square pipe for low pressure transmission is mainly used for low pressure water, oil, natural gas, heating and other pipelines.
8, used for transportation of flammable and non-flammable liquid, square pipe, mainly used for transportation of low-pressure or high-pressure square pipe flammable and non-flammable liquid, relatively high requirements.
