Heavy-Duty Wedge Wire Tubes
Built for the Toughest Filtration Challenges. Our reinforced wedge wire tubes are engineered to withstand extreme differential pressures and abrasive media where standard screens fail.
Technical Intro
Engineered for Structural Integrity
When your filtration process involves high-viscosity fluids, high-pressure backwashing, or abrasive solids, a standard screen isn't enough. Our Heavy-Duty Wedge Wire Tubes feature oversized support rods and specialized welding techniques to ensure maximum collapse and burst resistance.
Each tube is custom-manufactured to balance high open area with the mechanical strength required for heavy industrial use in mining, oil & gas, and pulp processing.

"Heavy-Duty" Advantages
Abrasive Resistance
Thicker profile wires provide a larger "wear zone," significantly extending service life in mining and slurry apps.
Robust Welds
Advanced resistance welding ensures every wire-to-rod intersection can handle high-frequency mechanical vibration.
Custom Reinforcement
We can add external cage supports or internal stiffening rings for ultra-large diameter tubes.
Quality Control
Integrity is non-negotiable. Every heavy-duty tube undergoes rigorous quality checks, including:
Collapse Pressure Testing
Slot Uniformity Verification (Microscopic)
Material Grade PMI Testing
Weld Strength Analysis
We provide full Material Test Reports (MTRs) and structural certificates for every shipment.`
Applications
Mining & Aggregates: Dewatering and classification of abrasive iron ore or coal slurries.
Pulp & Paper: Fiber recovery and thickening processes.
Deep Sea Intake: Durable screen tubes for offshore platforms and desalination plants.
Oil & Gas: High-pressure sand control and reactor internals.
Frequently Asked Questions
It’s defined by the ratio of the support rod mass to the profile wire. We use thicker support rods and closer rod spacing to increase the structural modulus.
A: Yes, we specialize in “drop-in” replacements for major industrial filter brands, ensuring the flanges and lengths match your existing specs perfectly.
For heavy-duty seawater applications, we recommend Duplex 2205 or Super Duplex for their combined high strength and superior pitting corrosion resistance.
