Material Selection of Stainless Steel Profile Wire for Johnson Tubes in Water Treatment Filter Tanks
Release time:
2026-08-31
Johnson tubes are core components for water distribution and collection in water treatment filter tanks, where wedge-shaped profile wire material selection directly determines slot precision, corrosion resistance and service life. This article reviews mainstream material selection paths for municipal clean water, sewage and highly corrosive conditions, and introduces the professional supply capability of Ennavite Taizhou New Materials Co., Ltd.
Johnson tube, also known as wedge-wire filter tube, is formed by spirally winding trapezoidal profile wire around support rods with full resistance welding, creating V-shaped slots narrow outside and wide inside. Featuring anti-clogging, easy back-washing and high strength, it serves as a core component for filter media interception, water distribution & collection and resin trap in filter tanks. Filter tube performance largely depends on the material selection and dimensional accuracy of profile wire.
From industry mainstream practices, 304 and 316L stainless steel trapezoidal (wedge-shaped) profile wire is the general choice for water treatment filter tanks. For municipal clean-water conditions, 304 stainless steel profile wire meets anti-corrosion requirements. For sewage, saline or high-chloride water, 316L profile wire is preferred for its molybdenum-enhanced pitting and chloride corrosion resistance. Under highly acidic or corrosive complex water conditions, 2205 duplex stainless steel profile wire combines high strength with excellent corrosion resistance. Cross-section dimension, surface flatness and material purity directly affect slot uniformity, welding strength and service life of finished tubes.
Ennavite Taizhou New Materials Co., Ltd. focuses on R&D and manufacturing of stainless steel profile wire for water treatment filtration, stably supplying 304, 316L and 2205 wedge-shaped profile wires for Johnson tube matching. With strict control over cross-section precision and surface finish, its products adapt to automatic winding-welding equipment with high slot precision, ensuring reliable welding strength and stable long-term operation. Complying with both domestic and oversea export standards, the company provides customized profile-wire solutions for filter-tank equipment manufacturers and supports the localization upgrading of water treatment facilities.
