Product Overview
Anti Corrosion Wedge Wire Screen Pipe is precision-engineered filtration and structural support component designed for long-term deployment in aggressive operational environments. They are constructed by welding trapezoidal profile wires onto support rings or longitudinal rods to form robust, continuous, and uniformly slotted cylinders. Unlike standard stainless steel screens, these tubes incorporate advanced protective coatings-such as epoxy (EP) or polyethylene (PE)-applied over high-strength substrates. This design ensures reliable solid-liquid separation, particle retention, and structural integrity in corrosive conditions, including saline, acidic, alkaline, or contaminated media.

Product Advantages
● Engineered Corrosion Barrier
The polymeric coating (EP/PE) acts as a dielectric barrier, isolating the base metal from corrosive electrolytes to prevent galvanic and under-deposit corrosion. Per ASTM B117 salt spray tests, coated carbon steel substrates show no base metal corrosion for >1000 hours, versus 24-72 hours for uncoated steel.
● Mechanical Integrity with Coating
The all-welded construction provides structural strength, with coated pipes maintaining a crush resistance of 0.8-2.0 MPa (diameter and material dependent). Coating adhesion strength ≥10 MPa (per ISO 4624) ensures integrity under handling and operational stress.
● Consistent Hydraulic Performance
Controlled coating application preserves V-slot geometry for stable separation cut-points and reduced blinding. Open area (10-30%, slot size dependent) supports high flow rates with low pressure drop.
● Reduced Total Cost of Ownership
Corrosion protection extends service life 3-5x versus uncoated carbon steel, and surpasses standard stainless steel in aggressive media (e.g., high chloride, low pH), lowering replacement frequency, downtime, and disposal costs.
