Frequently Asked Questions (FAQ)
-
Q: What is the difference between a wedge filter and a wire mesh filter?
A: A wedge filter uses continuous V-shaped wedge wire wound around support rods, creating precise slot openings that are non-clogging and self-cleaning. In contrast, woven wire mesh filters have a more random opening pattern and can clog more easily. Wedge filters offer higher strength, better flow, and longer life for demanding applications. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide samples for evaluation. The sample cost and shipping will be discussed. For standard sizes, we can ship a sample within 5–7 working days after confirmation. -
Q: What stainless steel grades do you recommend for corrosive environments?
A: For general water treatment, SS304 is suitable. For seawater or chemical processing, SS316L is recommended. For highly acidic or high-chloride environments, we can supply 904L, Duplex, or other super austenitic grades. Please provide your operating conditions for a precise recommendation. -
Q: How do you ensure slot opening accuracy?
A: Our manufacturing process uses precision coil winding and laser welding. Each filter is inspected with feeler gauges and optical measuring tools to ensure the slot tolerance is within ±0.02 mm for fine openings and ±0.1 mm for larger openings. -
Q: What is the maximum length of a single piece wedge filter?
A: Standard single-piece length is up to 6000 mm (6 meters). Longer lengths can be achieved by welding multiple sections together. We can also supply custom lengths according to your drawings. -
Q: Do you provide end connections such as flanges or threads?
A: Yes, we offer a variety of end connections including threaded (NPT, BSP), flanged (ANSI, DIN, JIS), welded stub ends, and compression fittings. Please specify your connection type when ordering. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, 15–20 working days. For custom dimensions or special materials, 20–30 working days depending on complexity. We will confirm the exact lead time after order confirmation. -
Q: How do you pack the wedge filters for export?
A: We pack each filter individually with protective wrapping, then secure them in wooden crates or steel frames to prevent damage during transit. For small orders, we use strong cardboard tubes or cartons.
