Spiral Welded Perforated Tubing Superior for Its Precision Spiral Welding

Spiral welded perforated pipe is helically formed and automatically welded of continuous sheets of perforated metal based on high precision and high quality of welding. Compared with straight welded tube, spiral welded tubing is approximately 15% stronger. Spiral metal tube does great job in holding high pressure and high impacts.

Spiral welded tubing has been processed by centerless grinding, plating, sand blasting, deburring and buffing. These finishes will make subsequent operations smooth and cost-efficient.

Welded spiral perforated tube is available in various margin and end patterns. See them in technology section.
