Pipe material steel pipe refers to the pipe diameter and wall thickness ratio of less than 20. Pipe Material steel pipe is the pipe diameter and wall thickness ratio of less than 20 steel pipe. Mainly used in petroleum geology drilling pipe the petrochemical cracking tube, boiler tubes, the bearing tube as well as automobiles, tractors, aviation high-precision structural tube.
The biggest difference between thick wall steel pipe and thin wall steel pipe is the pipe wall thickness, in general, are drawn thin-walled steel technology, and general use of hot-rolled thick-walled steel pipe technology, if it is used to distinguish between units of measure, then, generally, the wall thickness / diameter equal to 0.02 is thick and thin-walled steel pipe watershed, wall thickness / diameter less than 0.02 thin-walled steel pipe, thick wall steel pipe is greater than in the purposes, the thin-walled steel multi-purpose the pipe. The multi-walled steel hollow parts used in the blank. Pressure as well as an important channel to use.
