Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and certified with ISO9001, specializes in producing high-quality valves and filtration equipment for global markets. Our CB/T497 A-Type Seawater Strainer is engineered for robust performance in demanding marine environments, effectively protecting critical seawater intake systems from debris and particulate contamination. With an annual export value ranging from US$1 Million to US$1.5 Million, we supply reliable products to diverse regions including North America, Southeast Asia, Europe, and Africa, ensuring our strainers meet the rigorous standards required by international clients.
This strainer is a crucial component for seawater cooling systems, firefighting systems, ballast water management, and other onboard applications where clean seawater is essential. Its design prevents clogging and damage to pumps, heat exchangers, and other downstream equipment, thereby reducing maintenance costs and enhancing operational reliability.
Key Features and Technical Specifications:
- Standard Compliance: Manufactured according to the Chinese CB/T497 standard, ensuring design consistency and quality for marine applications.
- Pressure Rating: Rated at PN1.0MPa (approximately 10 bar), suitable for typical seawater system pressures.
- Size Versatility: Available in a comprehensive range of flanged sizes from DN50 to DN300, accommodating various pipeline diameters and flow requirements.
- Durable Construction: Typically constructed from robust materials such as cast iron, with options for stainless steel or other corrosion-resistant alloys for enhanced longevity in saline environments.
- Efficient Filtration: Utilizes a removable mesh basket strainer element that captures solids and debris. The mesh size can be customized based on specific filtration needs.
- Flanged Connection: Standard flanged ends (e.g., DIN, ANSI, JIS standards available upon request) facilitate secure and leak-proof installation into existing piping networks.
- Easy Maintenance: Designed for straightforward access and cleaning. The basket can be easily removed for inspection and debris removal without disassembling major piping.
- Seawater Compatibility: Materials and seals are selected to withstand the corrosive nature of seawater, promoting long service life.

Frequently Asked Questions (FAQ):
-
Q: What is the primary function of this A-Type Seawater Strainer?
A: Its primary function is to filter solid particles and debris from seawater before it enters pumps, cooling systems, or other onboard equipment, thereby preventing clogging and damage. -
Q: What does "PN1.0MPa" pressure rating mean?
A: PN1.0MPa indicates the strainer is designed to withstand a nominal pressure of 1.0 Megapascal (approximately 10 bar), which is a common pressure rating for many seawater intake and circulation systems. -
Q: Are the flanged connections standardized?
A: Yes, the strainer features standard flanged ends. The specific flange standard (e.g., DIN, ANSI) can be specified according to your project requirements or existing piping. -
Q: Can I get this strainer in stainless steel instead of cast iron?
A: Yes, stainless steel construction is an available option for enhanced corrosion resistance in particularly aggressive seawater environments or for specific client preferences. -
Q: How often does the filter basket need to be cleaned?
A: Cleaning frequency depends on the debris load in the seawater. The strainer is designed for easy access, allowing for regular inspection and cleaning as part of routine maintenance schedules. -
Q: Is the mesh size of the basket filter fixed?
A: No, the mesh size of the removable basket is customizable. You can specify the mesh opening size (e.g., 1mm, 2mm, etc.) based on the size of particles you need to filter out. -
Q: Does this product come with any international certifications?
A: Our manufacturing process is certified with ISO9001, ensuring consistent quality management. The product itself is manufactured according to the Chinese CB/T497 standard for marine strainers. -
Q: What are the main applications for this seawater strainer?
A: Typical applications include seawater cooling systems for engines and generators, marine firefighting systems, ballast water treatment systems, and any onboard process requiring filtered seawater.
