Perforated Filter Pipe – Straight, Spiral, Welded, Lock Seam Pipes
Perforated pipe is mainly applied to a variety of filtration industry such as, mining, petroleum, chemical, food, medicine, petroleum, water treatment and so on. Perforated pipe is made of steel punching mesh with galvanized layer, stainless steel punching mesh, copper punching mesh, in which the most punching steel mesh applied is stainless steel punching mesh. Fabrication methods are welded or lock seam. Welding types include straight line and spiral welded. Perforated pipe can be customized matching with a variety of machines such as, conical, wedge-shaped, basket-shaped, V-shaped, cylindrical, etc.
