Single Walled Steel Tubing (Hycolin®)
Hycolin® is an electric resistance welded steel tube specially made, which is manufactured from electrolytic metal-coated steel strip (one surface). The strip is wound into tubular and then welded together on both edges to form continuous strip.
This tube possesses higher withstanding pressure and excellent mechanical properties. And further more, is also equipped with the superior reliability on bending process and end terminal forming process. The tube is applied for several purposes such as fuel pipes and oil pipes on vehicles, tubes for heat exchanger, and pipes for hydraulic piping.
