Perforated Tubes and Pipes - High Strength for Filter Protection

A perforated tube, also known as perforated pipe, is a type of metal filter cartridge made from flat perforated plates then rolled and welded to a tube.
With high strength and deformation resistance, they perform well in holding and protecting fine filter mesh. They are widely used for filtration of air, liquid, oil, dust glass, coal or other chemicals, medicine, food or plastic industries, etc. No matter what the application, Filtalloy will design and adjust to fit clients’ needs.
