Reversed plain dutch weave mesh

Reversed plain dutch weave mesh, also known as RPDW, is a robust and fine filter mesh characterized by having more, thinner warp wires and fewer, thicker weft wires. This unique structure provides high mechanical strength and excellent resistance to high pressure.

 

It is a plain weave where the typical Dutch weave wire arrangement is reversed. Thin warp wires are positioned very close together, while thicker weft (shute) wires are woven in at defined intervals.

PRODUCT DESCRIPTION

 

This construction results in a mechanically strong mesh, particularly in the warp direction, making it highly stable and resistant to deformation.

 

The wires form triangular-shaped horizontal or transversal openings that run at an angle to the mesh surface, creating precisely defined pore openings. It provides a high active filtration cross-section and is excellent for fine filtration applications.

 

Backwashing Performance: Its robust structure and smooth surface make it highly effective in applications involving backwashing or mechanical cleaning processes.

 

The mesh is primarily made from materials like stainless steel, which offers good chemical, acid, alkali, and corrosion resistance. The most common material, including grades 304, 304L, 316, and 316L, known for their durability and corrosion resistance.

 

The mesh's strength and fine filtration capabilities make it popular in industrial solid-liquid separation and filtration.

Pressure Filtration: It is commonly used as a filter element in vertical and horizontal pressure leaf filters, which require high mechanical stability due to high operational pressure.

Centrifuges: Its robustness makes it suitable for use in centrifuges for effective filter cake removal.

Polymer and Plastic Processing: Used as continuous filter screens in polymer melt filtration and plastic extrusion industries.

Chemical & Petrochemical Industries: Utilized for various filtration needs in chemical processing, oil filtration, and sand control screens.
