Perforated Metal Tube

Perforated metal tube are made of aluminum, stainless steel, carbon steel and 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 metal tube surface is processed by electrolytic polishing, galvanization, sandblasting, pickling and passivation.


With durable materials and various models, perforated metal tube can filter liquids, solids and air or sieve different materials to ensure the purity. Weakening noise and granary ventilation are also their important functions. With good acid and alkali resistance, sieving tube is a very practical product for filtering ceramic powders, glass materials, plastic materials, soils, mineral aggregates, drug particles, metal powders, etc.
