Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience in producing high-quality industrial filtration components. Our Stainless Steel Candle Filter Skeleton is engineered specifically for demanding chemical processing environments, where reliability and durability are paramount. Made from premium 316L stainless steel, this filter skeleton offers exceptional resistance to corrosion, even in aggressive chemical media, ensuring long service life and consistent performance. Designed to withstand operating pressures up to 10 Bar, it is a robust solution for liquid filtration, solid-liquid separation, and catalyst recovery in various industrial applications.
Our candle filter skeleton serves as the core support structure for filter candles or filter bags, providing a stable framework that maintains shape under pressure and thermal stress. The 316L grade is chosen for its low carbon content, which minimizes the risk of intergranular corrosion during welding and high-temperature exposure. This product is manufactured in our facility in Hengshui, Hebei, China, with strict quality control from material selection to final inspection. We have exported to markets including North America, Europe, Southeast Asia, and Oceania, with annual export values exceeding US$5 million.

The candle filter skeleton is often used in combination with filter cloth, mesh, or sintered wire mesh to create a complete filter element. Our skeleton is designed to provide maximum open area while maintaining the mechanical strength needed to support the filter medium. This balance ensures high flow rates and efficient filtration, reducing pressure drop and energy consumption in your process.

In chemical processing, any malfunction in filtration can lead to downtime, product contamination, or safety hazards. Our 316L candle filter skeleton is built to resist pitting, crevice corrosion, and stress corrosion cracking, which are common in chloride-rich or acidic streams. The 10 Bar rating ensures that it can handle typical process pressures without deformation. Whether you are filtering catalysts, removing particulates from polymers, or clarifying acids, this skeleton will provide a reliable foundation for your filtration system.

Frequently Asked Questions (FAQ)
-
What is the difference between a filter skeleton and a filter candle?
Answer: A filter skeleton is the internal support structure that holds the filter medium (e.g., mesh, cloth, or sintered metal). The complete filter candle includes the skeleton plus the medium. Our product is the skeleton only, which can be used with your own filter media or we can supply the complete assembly upon request. -
Can this skeleton be used for high-temperature applications?
Answer: Yes, 316L stainless steel can withstand up to 400°C in continuous service. For higher temperatures, we can recommend alternative materials. Please specify your exact temperature range when ordering. -
Is the 316L material suitable for seawater or brine filtration?
Answer: 316L offers good resistance to chlorides, but for extremely high chloride concentrations or elevated temperatures, we may suggest a higher alloy like 904L or duplex stainless steel. Contact us for a material recommendation based on your specific fluid chemistry. -
What slot sizes are available for the skeleton?
Answer: Slot widths can be customized from 0.1 mm to 3 mm. The slot length and pattern are also adjustable to match your filtration requirements. We can produce wedge wire or punched slot designs. -
How do I clean the filter skeleton?
Answer: The open structure allows easy cleaning via backwashing, chemical cleaning, or ultrasonic cleaning. The smooth surface resists fouling, reducing maintenance frequency. -
What is the minimum order quantity (MOQ)?
Answer: For standard sizes, MOQ is 10 pieces. For custom sizes, MOQ may vary depending on complexity. We are flexible for samples and trial orders. -
Do you provide any certification or material test reports?
Answer: Yes, we can provide mill test certificates for the 316L stainless steel material upon request. Product performance testing is also available as an optional service. -
What are the shipping options available?
Answer: We ship from ports in Tianjin, Qingdao, Shanghai, and Foshan. We can arrange sea freight, air freight, or express courier. For large orders, FOB or CIF terms are commonly used.
