Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value exceeding US$5 million. Our 18° Sector Plate for Vacuum Filter is specifically engineered for chemical sludge treatment, offering exceptional corrosion resistance through premium 316L stainless steel. This component is critical for ensuring efficient dewatering and filtration in demanding industrial environments, reducing downtime and operational costs.
The 18° angle design is precisely machined to optimize cloth tension and seal integrity, preventing bypass and maximizing filtration efficiency. Whether you are upgrading existing equipment or building new systems, our sector plates deliver consistent performance under harsh chemical exposure.
Key Features & Benefits
- Corrosion Resistance: 316L stainless steel provides excellent resistance to chlorides, acids, and alkalis, extending service life in chemical sludge applications.
- Precision 18° Angle: Ensures proper sealing with filter cloth, reducing leakage and improving vacuum efficiency.
- Durable Construction: Laser-cut and formed with tight tolerances, withstands mechanical stress and repeated cleaning cycles.
- Customizable Dimensions: We offer tailored sizes, thicknesses, and hole patterns to fit various vacuum filter models (e.g., EIMCO, Peterson, Dorr-Oliver).
- Low Maintenance: Smooth surface finish minimizes cake adhesion and simplifies cleaning, reducing labor costs.
- Broad Application Range: Suitable for chemical sludge dewatering, mining, wastewater treatment, and food processing.

Our sector plates are manufactured using advanced CNC laser cutting and precision forming, ensuring consistent quality from batch to batch. The 18° angle is critical for optimal vacuum distribution and cake release, which directly impacts dewatering efficiency. By choosing 316L, you avoid pitting and crevice corrosion common in lower-grade stainless steels when exposed to chloride-rich chemical sludges.

Frequently Asked Questions (FAQ)
-
Q: What makes 316L better than 304 for chemical sludge treatment?
A: 316L contains molybdenum, which significantly improves resistance to chlorides, sulfuric acid, and other corrosive chemicals commonly found in industrial sludge. It also has lower carbon content, reducing carbide precipitation during welding. -
Q: Can you customize the hole pattern and size?
A: Yes, we can produce sector plates with any hole pattern, diameter, and thickness according to your drawings or samples. Customization is available upon request. -
Q: What is the typical lead time for an order?
A: For standard sizes, lead time is 15–20 days after deposit. Custom orders may require 25–30 days depending on complexity. -
Q: How are the sector plates packed for export?
A: They are packed in seaworthy wooden crates with foam inserts to prevent movement and scratches. Each plate is individually wrapped. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 10 pieces for standard sizes. For custom designs, MOQ is negotiable based on tooling. -
Q: Do you provide samples before bulk order?
A: Yes, samples are available. We can produce a sample matching your specification for evaluation. Sample cost is waivable for bulk orders. -
Q: How long does the sector plate last in acidic chemical sludge?
A: Service life depends on operating conditions (temperature, pH, chlorine concentration). In typical municipal and chemical sludge, 316L plates can last 3–5 years or more with proper maintenance. -
Q: Can you handle large quantity orders for mining projects?
A: Absolutely. Our factory capacity is over 50,000 pieces per month, and we have experience supplying large-scale mining and wastewater projects.
