Work Process

1.Materials
2.Cleaning

Remove oil and dirt.
3.Heating

Pipes are annealed using non-oxidizing heat treatment furnaces without scales for an extremely beautiful surface finish that does not require pickling.
4.End processing

Pipe ends are squeezed and processed by dedicated machines
5.Drawing

Cold draw processing provides a wide range of high-accuracy dimensions.
6.Cutting

Beautiful cut edges made possible with special tools.
The outer diameter is thin and the thickness is evenly drawn out, the hardened pipe is softened by annealing, and this process is repeated to finish to designated dimensions. The drawing and rolling meter is No. 1 in the industry.
7.Straightening

Multi-roll adjusting increases circular precision.
8.Non-destructive inspection

Eddy current flaw detection equipment enables high-accuracy scratch discovery.
9.Inspection

Product inspections are done carefully by each of our skilled inspectors who check every item visually.
10.Packaging and shipping
