As a leading manufacturer with over two decades of expertise, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Welded Cylindrical Filter Tube with a 20 micron rating, crafted from premium 304 stainless steel and a 0.8mm perforated sheet. Designed specifically for water treatment applications, this filter tube combines robust construction with precise filtration capabilities, ensuring reliable performance in demanding environments. Our factory, established in 1998 and exporting US$5-10 million annually to markets worldwide, brings you a product that meets the highest standards of durability and efficiency.
The cylindrical shape maximizes surface area, allowing for high flow rates while maintaining excellent particle retention. The 20 micron rating effectively removes suspended solids, sediment, and fine particles from water streams, making it ideal for pre-filtration, wastewater treatment, industrial process water, and more. Each tube is welded using advanced TIG technology to ensure seamless joints and long service life. The 0.8mm perforated sheet provides a sturdy base that resists deformation under pressure.
