As a professional manufacturer certified by ISO9001, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-quality marine equipment tailored for global shipbuilding and offshore industries. Our CB/T497-94 Marine Filter, supplied with a complete Mill Test Report for its material, represents our commitment to quality, traceability, and reliability. This product is engineered to meet the stringent demands of marine fluid systems, ensuring optimal performance and longevity in harsh maritime environments. By choosing our filter, you are investing in a component backed by documented material integrity and robust manufacturing standards, designed to enhance the safety and efficiency of your vessel's operations.
The core value of this marine filter lies in its adherence to the specific CB/T497-94 standard, which governs the design and manufacturing requirements for marine filters in China's shipbuilding sector. This compliance ensures compatibility and performance within a wide range of marine applications. Each unit is constructed from materials that have undergone rigorous testing, with the Mill Test Report (MTR) providing full traceability of the material's chemical composition and mechanical properties. This level of documentation is crucial for shipyards, classification societies, and vessel operators who require verifiable proof of material quality for safety audits and maintenance records.
Key Features and Technical Advantages:
- Standard Compliance: Manufactured in strict accordance with the CB/T497-94 standard, ensuring design integrity and acceptance in marine projects.
- Full Material Traceability: Every filter is accompanied by a Mill Test Report, certifying the material's grade, origin, and tested properties.
- Robust Construction: Available in materials like carbon steel or stainless steel to resist corrosion from seawater and onboard chemicals.
- Customizable Configuration: Filters can be tailored in terms of connection type (flanged, threaded), filtration fineness, and pressure ratings to suit specific system requirements.
- High Filtration Efficiency: Designed to effectively remove particulate contaminants from various fluids (fuel, lubricating oil, seawater), protecting downstream equipment.
- Easy Maintenance: Features such as a removable basket or element allow for straightforward cleaning or replacement, minimizing vessel downtime.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the CB/T497-94 standard for this marine filter?
A: The CB/T497-94 is a Chinese industry standard specifically for marine strainers and filters. Compliance ensures the product meets defined design, material, and testing criteria, making it widely accepted and specified in shipbuilding projects, particularly for vessels built to or operating under standards referencing Chinese regulations.
-
Q: Why is a Mill Test Report (MTR) important, and what information does it contain?
A: An MTR is a certified document from the material mill that verifies the chemical composition and mechanical properties (like tensile strength, yield strength) of the metal used. It is crucial for quality assurance, traceability, and is often required by classification societies (e.g., ABS, DNV, LR) during vessel construction and surveys to validate material suitability.
-
Q: Can this filter be customized for a specific pressure rating or connection standard?
A: Yes, customization is a key service we offer. We can manufacture filters to meet specific design pressures and fit connection standards such as ANSI flanges, JIS flanges, or various thread types (NPT, BSP) based on your system's piping specifications.
-
Q: What are the typical applications for this type of marine filter?
A: This filter is commonly used in various shipboard systems including fuel oil supply lines to engines, lubricating oil circuits for main and auxiliary engines, seawater cooling systems, ballast water treatment lines (pre-filtration), and compressed air systems to protect sensitive equipment.
-
Q: What materials are available for the filter body and element?
A: The main body is typically available in carbon steel (with protective coatings) for general use or stainless steel (304/316) for superior corrosion resistance. The filter element is usually made of stainless steel wire mesh, with the mesh size selected based on the required filtration fineness.
-
Q: How do I determine the correct mesh size or filtration grade for my application?
A: The selection depends on the fluid being filtered and the level of protection required for downstream equipment. We recommend consulting your equipment manufacturer's specifications or contacting our technical team with your system details (fluid type, flow rate, required cleanliness level) for a professional recommendation.
-
Q: What are your main shipping terms and delivery lead times?
A: We operate on standard international trade terms like FOB, CIF, or CFR. Lead times vary based on order quantity and customization level but are generally competitive. We ship from major ports in Shanghai, Guangzhou, Hongkong, and Beijing to ensure efficient global logistics to your destination.
-
Q: Do you offer any warranty or after-sales support for your marine filters?
A: Yes, our products come with a standard warranty against manufacturing defects. Furthermore, we provide comprehensive after-sales support, including technical documentation, installation guidance, and assistance with spare parts (like replacement elements) to ensure the long-term performance of your purchase.
