Seamless steel pipe is a kind of pipe with a hollow section and used in large quantities for conveying fluid. The production process of seamless steel pipe is to pierce a solid tube billet or steel ingot into a hollow capillary tube, and then roll it into a steel tube of the required size.
Main production process of hot-rolled seamless steel pipe (△main inspection process):
Tube billet preparation and inspection △→tube billet heating→perforation→tube rolling→steel pipe reheating→fixed (reduced) diameter→heat treatment△→finished pipe straightening→finishing→inspection△(non-destructive, physical and chemical, bench inspection)→storage
The Seamless steel pipe are mainly used in the pipeline construction of heavy industry, the main frame construction of light industry, and construction decoration industries.
