Thick-walled steel pipe

Update:2022-07-13   View(s):466   Keywords :Thick-walled steel pipe
Thick-walled steel pipes refer to steel pipes whose outer diameter and wall thickness ratio is less than 20 than thick-walled steel pipes. Mainly used as petroleum geological drilling pipe, cracking pipe for the petrochemical industry, boiler pipe, bearing pipe, and high-precision structural pipe for automobiles, tractors, etc.
The big difference between thick-walled steel pipes and thin-walled steel pipes is the thickness of the steel pipe wall. Generally speaking, thin-walled steel pipes are cold-drawn technology, while thick-walled steel pipes and thick-walled steel pipes generally use hot-rolling technology, if they are distinguished by units of measure. , then, it is generally believed that the wall thickness/pipe diameter equal to 0.02 is the watershed between thick-walled steel pipes and thin-walled steel pipes, those with wall thickness/pipe diameter less than 0.02 are thin-walled steel pipes, and those larger than 0.02 are thick-walled steel pipes. In terms of use, thin-walled steel pipes Wall steel pipes are mostly used on pipes. Thick-walled steel pipes are mostly used in blanks for hollow parts. Use on pressure-bearing and important pipelines. Thick-walled steel pipes are mainly used in water engineering, the petrochemical industry, the chemical industry, the electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structure: for piling pipe, for bridge; for wharf, road, building structure, etc.
