Description

Material Tracking Method for LSW Pipe

technical field

The invention relates to the technical field of material tracking, in particular to a material tracking method for straight seam welded pipes.

Material tracking is the basic component of the production management system and the basis of functional modules such as production performance, personnel management, and quality management. In order to realize the digitalization and intelligence of the welded pipe production line, material tracking is also implemented for welded steel pipes.

Longitudinal welded pipe refers to the pipe obtained by straight seam welding of hot rolled or cold rolled steel plate or steel strip welded steel pipe on welding equipment. The existing production process of straight seam welded steel pipe includes multiple processes, specifically in order Feeding, flaw detection, arc strike plate welding, edge milling, pre-bending, forming, pre-welding, internal welding and external welding (multi-line), cutting arc strike plate, diameter expansion, hydrostatic pressure test, flat head, weighing and measuring length , spray labeling, warehousing and other processes, as well as the transportation process between each process.
