After welding and grate removal, stainless steel pipes are cooled and pre-calibrated for diameter (or reduced), divided into several lengths and straightened.

Calibration .

It is carried out in mills which contain 3 to 4 two-roll stands with horizontal drive rolls and alternating non-transfer stands with vertical rolls. Mills for larger sizes include 3-4 four-roll stands with driven horizontal rolls. Immediately behind the mill, a non-transfer four-roll straight stand produces ovality removal in conjunction with straightening.

Cutting

Pipes are separated on the run with flying cutting or breaking devices. The cutting is usually done with circular knives fixed on a cage rotating around the pipe. In the process of cutting, the knives converge. Breaking devices are used in mills for large sizes. In order to obtain a better quality of pipe ripping, an inductor is installed that heats up the narrow annular zones of the pipes at the point of rupture.

Productivity of Tube Fracturing Mills

Depending on the type of pipes being produced, as well as the welding procedure used. Capacity of different mills varies from 1 thousand to 1 million tons per year. The coefficient of metal consumption is - 1.04-1.09, with the corresponding specific power consumption.
