Steel Tube Marking
Definition of Task
- Large diameter welded steel tubes from 10 to 45 cm are continuously marked with a single line of text in a character height of 48 mm with logos and production data
Special Product Specification
- About 8 to 10 seconds after the coding process takes place the pipes pass a fluid curtain. This liquid is a cooling agent with chemicals added which first cools the still hot weld seam of the pipe and secondly protects the steel surface from rust
- The coding and marking process takes place in a typical steel industry environment which has high humidity and a higher level of dirt and air born particulates
