Straight Seam Welded Perforated Tube

Straight line welding and spiral wound welding are two major weld processing for the perforated metal tubes. Perforated pipes or tubes welded in straight line needs simple processing at low cost. Straight welded tubes have less strength compared with the spiral wound welded perforated metal pipes, with decreased welding seams at 30% to 100% rates.
