Shanghai Zhibang Valve Manufacture Co., Ltd., a trusted manufacturer established in 2016, specializes in producing high-quality marine fluid control components. With an annual export value ranging between US$1 Million and US$1.5 Million and ISO9001 certification underpinning our production processes, we are committed to delivering reliable solutions for global markets. Our CB/T497 Standard Seawater Filter with Flanged Connection represents a core product designed for robust performance in demanding seawater environments, offering shipbuilders, offshore platform operators, and marine system integrators a dependable filtration solution that enhances system longevity and operational safety.
This seawater filter is engineered to meet the specific requirements of marine applications where untreated seawater can contain solids, sediments, and other particulates that threaten pumps, valves, and sensitive equipment. By integrating this filter into your seawater intake or processing lines, you protect downstream components from abrasive wear, clogging, and corrosion, thereby reducing maintenance costs and downtime. The flanged connection design ensures a secure, leak-resistant interface with piping systems, facilitating straightforward installation and replacement.
Key Features & Technical Specifications:
- Standard Compliance: Manufactured according to the CB/T497 standard, ensuring dimensional consistency, material suitability, and performance benchmarks recognized within the marine industry.
- Connection Design: Features a robust flanged connection, compatible with standard piping flanges from DN80 to DN250. This design provides a strong mechanical joint, suitable for high-pressure systems and easy integration.
- Size Range: Available in nominal diameters from DN80 (approximately 80mm) to DN250 (approximately 250mm), catering to various flow capacity requirements in seawater cooling, ballast, firefighting, or desalination pre-treatment systems.
- Filtration Function: Effectively captures and removes suspended solids, sand, algae, and other impurities from seawater, protecting pumps, heat exchangers, and valves from damage and fouling.
- Construction Materials: Typically constructed from corrosion-resistant materials such as coated carbon steel, stainless steel, or specialized alloys to withstand the corrosive nature of seawater and marine atmospheres.
- Operational Benefits: Enhances the efficiency and lifespan of connected equipment, reduces frequency of maintenance, and contributes to overall system reliability in marine operations.

Frequently Asked Questions (FAQ):
-
What is the CB/T497 standard?
CB/T497 is a Chinese national standard related to marine piping components. It specifies requirements for dimensions, materials, testing, and performance for certain types of marine filters and strainers, ensuring they meet baseline criteria for marine use. -
Can this filter handle high-flow seawater applications?
Yes. The available size range up to DN250 is suitable for moderate to high flow rates common in main seawater intake lines, cooling systems, or ballast water treatment pre-filtration. -
What materials are typically used for the filter body?
Common options include carbon steel with epoxy or other protective coatings for cost-effectiveness, or stainless steel (304/316) for enhanced corrosion resistance in more aggressive environments. Material selection can be customized based on your seawater conditions and budget. -
Is the filter element replaceable?
Yes, most models feature a removable filter basket or screen element. When the element becomes clogged, it can be taken out for cleaning or replaced with a new one, restoring filtration efficiency without replacing the entire unit. -
How does the flanged connection benefit installation?
Flanged connections allow the filter to be bolted directly between two pipe flanges. This creates a strong, sealed joint that is easier to assemble and disassemble compared to welded connections, facilitating installation, maintenance, and potential future system modifications. -
What is the typical filtration level (micron rating)?
The standard filtration level can vary. Common seawater filters may have screen openings in the range of a few millimeters to capture larger debris. For specific micron ratings to capture finer particles, please inquire as custom elements may be available. -
Can you provide filters with different flange standards (e.g., ANSI, DIN)?
Yes. While the product adheres to CB/T497, the flange dimensions can often be manufactured to match common international standards like ANSI, DIN, or JIS upon request, ensuring compatibility with your existing piping. -
Do you offer pressure testing certificates or documentation?
As an ISO9001 certified manufacturer, we conduct quality checks including pressure tests. Relevant test reports or certificates can be provided upon request to support your project documentation needs.
