As a specialized manufacturer with a focus on marine fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our robust line of CB/T497 Marine Water Filters. Engineered specifically for the demanding conditions of seawater service, these filters are crafted from premium 316L stainless steel to ensure exceptional corrosion resistance and longevity. Designed for nominal diameters from DN50 to DN300, they provide reliable protection for critical shipboard systems, offshore platforms, and desalination plants by removing suspended solids and particulates from seawater intake lines.
Our filters are built to deliver consistent performance and minimize maintenance downtime in harsh marine environments. The core value lies in their durable construction, adherence to marine standards, and the ability to safeguard expensive downstream equipment like pumps, heat exchangers, and reverse osmosis membranes from abrasive damage and clogging.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: Constructed entirely from 316L stainless steel, offering excellent resistance to pitting and crevice corrosion in chloride-rich seawater environments, far surpassing the performance of standard 304 stainless steel.
- Compliant Design: Manufactured in accordance with the CB/T497 standard, ensuring compatibility and reliability within marine piping systems.
- Robust Filtration Core: Features a perforated stainless steel basket strainer with high open area, providing efficient particle retention while maintaining low pressure drop across the filter.
- Wide Size Range: Available in a comprehensive range of nominal diameters (DN50, DN80, DN100, DN150, DN200, DN250, DN300) to suit various flow rate requirements and pipeline configurations.
- Customizable Filtration: The mesh size of the basket strainer can be customized (e.g., 50 mesh, 100 mesh, etc.) to meet specific filtration grade needs for different applications.
- Easy Maintenance: Designed with a removable cover or top flange, allowing for quick and easy access to the basket strainer for inspection, cleaning, or replacement without disconnecting the main pipeline.
- Optional Enhancements: Configurations can include optional features such as pressure gauges to monitor differential pressure, blowdown valves for easy sediment purging, and bypass valves to ensure continuous system operation during maintenance.

Frequently Asked Questions (FAQ):
-
Q: Why is 316L stainless steel specified for this seawater filter instead of 304?
A: Seawater contains high levels of chlorides, which can cause pitting and crevice corrosion in standard 304 stainless steel. 316L contains molybdenum, which significantly enhances its resistance to this type of corrosion, making it the preferred material for prolonged exposure to seawater. -
Q: What does the "CB/T497" designation mean for this filter?
A: CB/T497 is a Chinese national standard specifically for marine pipeline filters. It defines dimensions, pressure ratings, testing methods, and material requirements, ensuring the product is suitable and reliable for use in shipboard piping systems. -
Q: Can I get a filter with a specific mesh size not listed?
A: Yes, the filtration grade is customizable. We can manufacture the stainless steel basket strainer with various mesh sizes (e.g., 30, 50, 80, 100, 150 mesh) or specify a micron rating to meet your precise filtration requirements. -
Q: How do I determine the correct nominal diameter (DN) for my application?
A: The DN size should match the nominal diameter of your existing pipeline to ensure proper flow and connection. You will need to know your system's flow rate and allowable pressure drop to select the most appropriate size. Our technical team can assist with this selection. -
Q: Is the filter suitable for high-pressure seawater systems?
A: The standard design pressure ratings are typically PN10, PN16, or PN25. For higher pressure requirements, the filter can be customized with a heavier body wall thickness and appropriate flange rating. Please specify your operating pressure during inquiry. -
Q: What maintenance is required for this type of filter?
A: Maintenance primarily involves periodic inspection and cleaning of the basket strainer. The frequency depends on the seawater solids content. The design allows the basket to be removed through the top opening for cleaning without pipeline disassembly. -
Q: Do you provide the filter with all necessary gaskets and bolts?
A: Typically, the filter is supplied as a complete unit, which includes the body, cover, basket strainer, and cover bolts/nuts. Gaskets for the main flange connections are often included, but it's advisable to confirm this detail in your purchase order. -
Q: What is the typical lead time for an order of DN200 filters?
A: Lead time depends on the order quantity and specific customization. For standard DN200 filters in 316L with common mesh sizes, production lead time is generally available upon request, and shipping can be arranged from major Chinese ports.
