As a professional manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-quality marine fluid control solutions. Our CB/T497 Seawater Filter is engineered to meet the rigorous demands of maritime applications, offering reliable protection for critical shipboard systems against particulate contamination. With an annual export value ranging between US$1 Million and US$1.5 Million, our products have gained trust in global markets including North America, South America, Europe, Asia, Africa, and Oceania. This filter combines robust construction with a comprehensive 12-month warranty and dedicated technical support, ensuring long-term performance and peace of mind for ship operators and marine engineers.
The CB/T497 Seawater Filter is designed for durability and efficiency in harsh marine environments. Its primary function is to remove suspended solids, sand, algae, and other debris from seawater, protecting downstream equipment such as heat exchangers, cooling systems, pumps, and desalination units from clogging, abrasion, and fouling. This directly contributes to reduced maintenance costs, extended equipment lifespan, and improved operational reliability.
Key Features & Technical Advantages:
- Corrosion-Resistant Construction: Manufactured from premium materials like 316L stainless steel or duplex steel, the filter body and internal components offer exceptional resistance to saltwater corrosion, pitting, and crevice corrosion, ensuring a long service life even in the most aggressive seawater conditions.
- High-Efficiency Filtration: Equipped with a robust filter element (screen or basket), it provides consistent filtration performance. The filtration grade is customizable to match specific system requirements, typically ranging from 50 to 500 microns.
- Low Pressure Drop Design: The internal flow path is engineered to minimize pressure loss across the filter, which helps in maintaining optimal flow rates and reducing the pumping energy required, leading to operational cost savings.
- Convenient Maintenance: Features a user-friendly design for easy inspection and cleaning. The filter basket or screen can be accessed and removed without disconnecting the main piping, simplifying routine maintenance and reducing downtime.
- Versatile Connection Options: Available with various end connections including flanged (ANSI, DIN, JIS standards), threaded (NPT, BSP), or grooved ends to ensure seamless integration into existing shipboard piping systems.
- Robust Pressure Rating: Designed to withstand standard marine system pressures. Common design pressures include PN10, PN16, and PN25, with higher ratings available upon request to suit high-pressure applications.

Frequently Asked Questions (FAQ):
-
Q: What is the main purpose of this seawater filter?
A: Its primary purpose is to physically remove suspended solids, sand, and debris from seawater before it enters sensitive shipboard systems like cooling circuits, heat exchangers, or desalination plants, thereby preventing clogging, abrasion, and efficiency loss. -
Q: How does the 12-month warranty work?
A: The warranty covers defects in materials and workmanship under normal use for a period of 12 months from the date of shipment. It includes repair or replacement of the defective unit, subject to our warranty terms and conditions. -
Q: Can this filter handle different flow rates?
A: Yes. The filter is available in various sizes and configurations to accommodate a wide range of flow rates. Providing your required flow rate and system pressure allows us to recommend the most suitable model. -
Q: What materials are offered, and which is recommended for highly corrosive environments?
A: We typically use 316L stainless steel, duplex steel (e.g., 2205), and bronze. For highly corrosive or chlorinated seawater (e.g., with high chlorine content from electrolysis), duplex steel or super duplex grades are often recommended due to their superior corrosion resistance. -
Q: Is the filter element easy to clean or replace?
A> Yes. The design prioritizes maintainability. The filter housing can typically be opened by removing a cover or cap, allowing direct access to the basket or screen for manual cleaning. No special tools are usually required for this routine operation. -
Q: What kind of technical support is provided?
A: Our technical support includes assistance with product selection based on your operating parameters, guidance on installation and commissioning, and troubleshooting advice during operation. Support is available via email, phone, or online communication. -
Q: Are custom connections or pressure ratings available?
A: Absolutely. We understand that marine systems vary. We can customize end connections (flange standards, threading) and design pressure ratings to meet your specific piping system and operational requirements. -
Q: What is the typical lead time for an order?
A: Lead time depends on the specification, quantity, and current production schedule. For standard configurations, it is generally shorter. We provide an estimated lead time with every quotation to help you plan your project.
