As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T497 316L Stainless Steel Water Filter. Engineered specifically for demanding marine applications, this flanged filter is a critical component for ensuring the integrity and efficiency of ballast water systems. Our years of expertise, backed by ISO9001 certification, are embodied in this robust product designed to meet the rigorous standards of the maritime industry. We understand the challenges faced at sea, and our filter is built to provide dependable performance, protecting vital equipment from particulate contamination and contributing to operational safety and environmental compliance.
Constructed from premium 316L stainless steel, this water filter offers exceptional resistance to corrosion, pitting, and crevice corrosion in chloride-rich marine environments. This material choice ensures a long service life and minimal maintenance, even under harsh operating conditions. The flanged design, compliant with CB/T497 standards, facilitates secure and leak-proof integration into existing piping systems with nominal diameters ranging from DN50 to DN200. The standard flanged connection simplifies installation and maintenance procedures, reducing vessel downtime.
Key Features and Technical Advantages:
- Superior Corrosion Resistance: The use of 316L stainless steel, with its added molybdenum content, provides outstanding protection against saltwater corrosion, making it ideal for ballast water treatment and other marine fluid handling systems.
- Robust Construction for High-Pressure Service: Designed to withstand the operational pressures commonly encountered in marine piping networks. The exact pressure rating can be customized based on specific project requirements.
- Efficient Filtration Performance: Effectively removes solid particles, sediment, and debris from ballast water, protecting pumps, valves, and treatment systems from abrasion, clogging, and premature wear.
- Standardized Flanged Connection: Ensures compatibility and easy installation with other flanged components in the pipeline, adhering to widely recognized maritime fitting standards.
- Durable and Low Maintenance: The sturdy stainless steel body and basket (or other filter element types available upon request) are designed for repeated cleaning and long-term use, offering excellent cost-efficiency over its lifecycle.
- Customizable Configurations: While the standard product follows CB/T497, options for different mesh sizes, pressure ratings, or specific flange standards (e.g., ANSI, JIS) are available to meet unique system specifications.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of using 316L stainless steel instead of 304 for this marine filter?
A1: 316L stainless steel contains molybdenum, which significantly enhances its resistance to pitting and crevice corrosion in chloride environments like seawater. This makes it a more suitable and durable choice for long-term marine applications compared to 304 stainless steel.
Q2: Can this filter be used for applications other than ballast water systems?
A2: Yes, absolutely. While designed for ballast water, this robust flanged filter is also suitable for other marine and industrial applications requiring the filtration of seawater, process water, or other fluids where corrosion resistance and particle removal are critical, such as cooling water systems or pre-filtration for desalination.
Q3: Are the flanges compatible with international standards like ANSI or JIS?
A3: The standard product is manufactured according to the Chinese CB/T497 standard. However, we can customize the flange dimensions, drilling, and facing to meet other common standards such as ANSI B16.5 or JIS B2220 upon request. Please specify your requirement during inquiry.
Q4: What types of filter elements are available, and how do I choose the right mesh size?
A4: We typically supply stainless steel wire mesh basket elements. The choice of mesh size (e.g., 30, 50, 100 mesh) depends on the size of particles you need to remove from the fluid. We recommend consulting your system design specifications or discussing your filtration goals with our technical team for the optimal selection.
Q5: How is the filter cleaned, and what is the maintenance interval?
A5: Maintenance involves isolating the filter from the line, removing the cover, and taking out the filter basket for cleaning. The interval depends entirely on the contaminant load in the water. The sturdy design allows for repeated cleaning. A pressure differential gauge (optional) can be installed to indicate when cleaning is needed.
Q6: Do you provide a pressure rating for this filter?
A6: The design pressure is customizable based on your system's operating pressure. Common ratings like PN10, PN16, or PN25 are available. Please provide your required pressure class so we can manufacture the filter to meet that specification safely.
Q7: What certifications does your company hold for quality assurance?
A7: Our manufacturing processes are certified under the ISO9001 Quality Management System, ensuring consistent quality control, traceability, and reliable production standards for all our valves and filters.
Q8: What is the lead time and packaging for export orders?
A8: Lead time varies based on order quantity and customization. Standard items typically have a shorter lead time. For export, products are securely packaged in wooden cases to prevent damage during ocean freight. We ship from major Chinese ports including Shanghai, Guangzhou, and Hong Kong.
