Perforated Filter Tube, AISI 304 Punching Hole Stainless Mesh Tube

Perforated tubes, also known as cylindrical filters, are versatile components manufactured from various durable sheet materials, including aluminum, stainless steel, carbon steel, alloy sheets, copper, black wire cloth, and galvanized steel.

The manufacturing process begins with designing the plate width and customizing the perforation pattern (opening diameter) based on specific requirements. Holes are then punched into the flat sheet. Subsequently, these perforated plates are precisely rolled into either a spiral or straight tube configuration. The seams are securely joined using argon arc welding, ensuring uniform welds and good pressure resistance. To further enhance performance, durability, and appearance, the surface of the finished tubes can undergo treatments such as electrolytic polishing, galvanization, sandblasting, or pickling and passivation.

These stainless steel Perforated tubes are characterized by several key features: 

accurate roundness and straightness; 

a smooth and flat surface; 

high filter precision. 

Their robust construction provides excellent resistance to pressure, acids, alkalis, and both low and high temperatures, contributing to a long service life.

Application

Perforated Filter Tube plays an important role in many applications.

Perforated Tube Filter is widely used in petroleum, chemistry, metallurgy, machine, medicine, sewage water filtration, automobile industries for distillation, absorption, evaporation and filtration processes, so as to eliminate the impurity and foam mixed in the gas and liquid.
