Product Overview
The Polished Wedge Wire Screen Pipe Stainless Steel is a precision-engineered filtration component designed for demanding solid-liquid separation processes. Manufactured through automated resistance welding of V-profile wires onto longitudinal supports, this product features continuous, uniform slots with precisely controlled apertures. The final electropolishing process achieves a surface roughness (Ra) below 0.8 µm, significantly enhancing its operational efficiency and cleanability. As a high-performance variant of wedge wire screen technology, the Polished Wedge Wire Screen Pipe Stainless Steel is specifically developed for applications requiring superior surface finish and non-stick properties.

Product Advantages
The electropolished surface reduces particle adhesion by approximately 40% compared to standard mill finish, directly decreasing blinding rates in viscous media. The monolithic, all-welded construction provides a collapse pressure resistance exceeding 5.0 MPa (approx. 725 psi) for standard diameters, ensuring structural integrity under high differential pressure. Slot uniformity, maintained within a ±0.02 mm tolerance for critical sizes, guarantees consistent separation accuracy and repeatable process results. The V-wire profile design promotes a self-cleaning effect, allowing efficient backwash and minimizing maintenance downtime.
Product Applications
The Polished Wedge Wire Screen Pipe Stainless Steel is specifically engineered for applications requiring smooth flow, high hygiene standards, and reliable filtration performance:
- Pre-Filtration & Guard Filters: In petrochemical and chemical processing for catalyst retention and protection of downstream equipment.
- Food, Beverage & Pharmaceutical: For product polishing and final filtration where CIP/SIP compatibility and material purity are essential.
- Slurry Dewatering & Classification: In mineral processing and wastewater treatment for precise particle size separation.
- High-Viscosity Fluid Processing: Effective filtration of polymers, syrups, and adhesives where reduced surface adhesion is critical to throughput.
