Perforated Tube for Filter Liquids, Solids and Air Filtration

Perforated tube is also called perforated pipe, perforated steel tube, perforated steel pipe or filter pipe. Its made of high quality carbon steel, stainless steel, aluminum or aluminum alloy sheet. According to opening diameter, we design the width of plate and punch holes customized by you. Then these plates are rounded in a spiral or straight strip and welded by argon arc welding.

The perforated filter tube surface is processed by electrolytic polishing, galvanization, sandblasting, pickling and passivation. It is corrosion and rust resistant. Perforated tube features the high strength, perfect recyclability and long service life, including straight perforated pipe, spiral perforated tube and perforated casing tube.

With durable materials and various models, perforated tubes can filter liquids, solids and air or sieve different materials to ensure the purity. Weakening noise and granary ventilation are also their important functions.

Application

Perforated tubes can be used as various frames of filter elements (inner and outer support tubes) for filtering liquids and air, such as water, oil, etc. And can also be used as an exhaust pipe (silencer) for automobiles and motorcycles. In addition, it can also be used as a smoker tube.
