The use of thick-walled steel pipe and the difference between the thick-walled steel pipe and the thin-walled steel pipe, the ratio of the outer diameter and wall thickness of the steel pipe is less than 20 thick steel pipe. It is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe, and high-precision structural pipe for automobiles, tractors and aviation.
The biggest difference between thick-walled steel tubes and thin-walled steel tubes is the thickness of the steel tube walls. Generally speaking, thin-walled steel tubes are cold-drawing techniques, while thick-walled steel tubes generally use hot-drawing technology. If they are differentiated by measurement units, then It is generally accepted that the wall thickness/diameter equal to 0.02 is the watershed of the thick-walled steel pipe and the thin-walled steel pipe. The wall thickness/diameter of less than 0.02 is a thin-walled steel pipe, which is larger than a thick-walled steel pipe. In terms of use, the thin-walled steel pipe is commonly used. On the pipeline. Thick-walled steel tubes are mostly used for blanks in hollow parts. Pressure and use on important pipelines.
