Thick wall steel pipe

What is thick wall steel pipe?

Thick-walled steel pipe, the steel pipe with the ratio of the outer diameter of the steel pipe to the wall thickness is less than 20 is called the thick-walled steel pipe. Mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural pipe for automobile, tractor, aviation, etc.

The biggest 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.

Application of thick wall seamless pipe:

Thick-walled steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: for piling pipes, for bridges; for wharfs, roads, building structures, etc.
