As a dedicated manufacturer of marine fluid control solutions since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T497 Sea Water Strainer A Type. Engineered for reliability in the harshest marine environments, this strainer is a critical component for protecting your vessel's engine cooling system, fire pumps, and other seawater-dependent equipment from debris, sand, and marine organisms. Its core value lies in the robust, replaceable 304 stainless steel mesh filter basket, offering superior corrosion resistance and durability compared to conventional materials, ensuring uninterrupted operation and reduced maintenance costs over the long term.
Our strainer is designed with practicality and performance as top priorities. Below is a detailed breakdown of its features, specifications, and the tangible benefits it delivers to ship operators and marine engineers.
Core Product Features & Technical Advantages:
- Premium Replaceable Filter Basket: The heart of the strainer is a basket woven from high-grade 304 stainless steel wire mesh. This material offers excellent resistance to saltwater corrosion, pitting, and biological fouling, maintaining filtration integrity far longer than plastic or coated alternatives.
- Easy Maintenance Design: The strainer features a bolted, easy-open cover. This allows for rapid visual inspection, cleaning, or replacement of the filter basket without requiring specialized tools, minimizing vessel downtime during routine servicing.
- Robust Construction: The main body is typically constructed from marine-grade cast iron or bronze, coated with anti-corrosive paint suitable for seawater service. This ensures structural integrity under pressure and vibration.
- Compliant Design: Manufactured in accordance with the Chinese CB/T497 standard for marine strainers (Type A), it meets common industry specifications for design, pressure rating, and dimensions, facilitating easier integration into new builds or retrofit projects.
- Versatile Filtration: The mesh size of the stainless steel basket is customizable upon request to suit specific application needs, whether it's fine filtration for sensitive equipment or coarse screening for ballast water.
- Optimized Flow Path: The internal design minimizes pressure drop across the strainer, ensuring efficient fluid flow to downstream equipment without imposing excessive load on supply pumps.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a 304 stainless steel filter basket over a plastic one?
A: 304 stainless steel offers vastly superior corrosion resistance in seawater, higher mechanical strength to withstand pressure and cleaning, and better resistance to UV degradation and organic growth, leading to a much longer service life and more reliable filtration. -
Q: Is the entire strainer body made of stainless steel?
A: Typically, the main body is constructed from marine-grade cast iron or bronze with protective coatings, as these materials provide excellent pressure-bearing capability at a competitive cost. The key filtration element—the basket—is 304 stainless steel. All-stainless steel bodies are available upon request. -
Q: How often does the stainless steel mesh basket need to be replaced?
A: With proper maintenance (regular cleaning), the 304 stainless steel basket can last for many years. Replacement is usually only necessary if the mesh is physically damaged. Its replaceable design makes this a simple and cost-effective process. -
Q: Can you provide strainers with different connection standards (e.g., ANSI, JIS)?
A: Yes. While the CB/T497 standard is common, we regularly manufacture strainers with flanges or threads matching ANSI, JIS, DIN, and other international standards. Please provide your connection specifications when inquiring. -
Q: What is the typical delivery time for an order?
A: For standard models and sizes, delivery can be relatively quick. For customized specifications (special sizes, materials, pressures), lead times will be provided based on the project complexity. We ship globally from multiple Chinese ports. -
Q: Do you offer a strainer with a duplex (dual) basket design for continuous operation?
A: The CB/T497 Type A described is a single-basket strainer. However, we manufacture a range of marine strainers. Duplex or twin-basket strainers that allow switching flow for uninterrupted operation during cleaning are available. Please inquire for models. -
Q: How do I determine the correct mesh size for my application?
A: The required mesh size depends on the equipment you are protecting. For main engine cooling water intake, a common mesh is 0.75mm to 1.5mm. For finer filtration, such as for freshwater generator feed, a smaller mesh (e.g., 0.5mm) may be needed. Our technical team can advise based on your system details. -
Q: Are installation instructions and a parts diagram included?
A: Yes, each strainer is shipped with comprehensive documentation, including installation guidelines, a detailed parts list, and dimensional drawings to assist with proper integration into your piping system.
