Buoy Shackle Type B

Product Design Features

Structural Design: The Buoy Shackle Type B features a unique leg-and-body structural design, manufactured by the Chinese facility CSAC Chain. This structural configuration is precisely tailored to specific mooring requirements, while simultaneously maintaining superior load-bearing capacity. It facilitates the smooth transmission of loads, effectively preventing stress concentration.

Profile Compatibility: The shackle's profile has been meticulously engineered to achieve a perfect fit with buoy chains. This ensures connection stability even under complex sea conditions, minimizes wear at the connection points, and extends the overall service life of the entire mooring system.

Safety Assurance: The product design places a strong emphasis on safety during offshore operations. Its compact structure and robust connections effectively prevent accidental detachment, making it ideally suited for the rigorous and demanding environments associated with long-term offshore operations.

Product Advantages

• Material and Manufacturing Process Advantages

Our Buoy Shackle Type B is manufactured using high-strength steel, offering customers a choice between two material options: forged or cast. This flexibility allows us to adapt the product to suit the specific operational scenarios and requirements of each client. The forging process eliminates internal material defects and refines the grain structure, thereby significantly enhancing the shackle's mechanical properties and fatigue resistance. Conversely, the casting process is ideal for meeting mass production demands, offering an optimal balance between cost-effectiveness and practicality. All products undergo advanced heat treatment processes—specifically quenching and tempering—to modify the metal's microstructure. This process increases the product's hardness and wear resistance while retaining sufficient toughness to prevent brittle fracture, thereby ensuring the stability of the Buoy Shackle Type B under heavy loads and complex operating conditions.

• Corrosion Resistance Advantages

To combat the highly corrosive, high-salinity, and high-humidity environments typical of offshore operations, the Buoy Shackle Type B is treated with either hot-dip galvanization or a specialized anti-corrosion coating. Both coating options effectively create a barrier that prevents direct contact between the steel substrate and seawater or moisture. This significantly enhances the product's corrosion resistance, extends its service life in marine environments, and reduces maintenance costs. The hot-dip galvanized coating offers strong adhesion and long-lasting corrosion protection, while the specialized anti-corrosion coating can be customized to suit specific operational environments—such as highly corrosive marine regions—thereby further elevating the level of corrosion protection.

• Quality Inspection Advantages

Every single Buoy Shackle Type B undergoes a rigorous quality inspection process. This comprehensive regimen includes various testing procedures—such as non-destructive testing, tensile testing, and load testing—to ensure that each product fully complies with international classification society certification standards as well as our company's own internal quality control requirements. Our entire inspection process is fully traceable, and all testing data is meticulously retained and archived. From the moment raw materials enter our facility until the finished products leave for shipment, every single stage is rigorously monitored by specialized personnel. 

• Specifications and Customization Advantages

Buoy Shackle Type B standard specifications cover 40mm to 90mm, accommodating different sizes of buoy chains and mooring systems to meet the needs of most offshore engineering and port operations. Furthermore, we offer comprehensive customization services for non-standard specifications. Based on customer-provided technical drawings, dimensional parameters, and specific operational scenarios, we can tailor-make Type B Buoy Shackles that precisely align with unique requirements—thereby resolving complex connection challenges encountered in specialized working environments and enhancing overall product versatility.

FAQ

Q1: What is the difference between the Type B Buoy Shackle and the Type A Buoy Shackle?

A1: The fundamental difference between the two lies in the structural design of their bodies (legs). The Type B Buoy Shackle features a unique body configuration that is better tailored to specific mooring requirements; while maintaining excellent load-bearing capacity, it is designed to accommodate specific sizes of buoy chains and mooring scenarios. Conversely, the Type A Buoy Shackle is suitable for general buoy mooring applications and features a more universal structural design. Customers can select the appropriate type based on their specific operational needs.

Q2: What is the lead time for standard sizes of the Type B Buoy Shackle?

A2: For standard sizes (40mm–90mm) of the Type B Buoy Shackle, we maintain a certain level of stock inventory, allowing us to ship orders within 3–7 business days after confirmation. If custom, non-standard sizes are required, the lead time depends on the complexity of the customization and the order quantity; typically, this takes 10–15 business days. For specific details, please consult our customer service team.

Q3: How long does the anti-corrosion coating on the Type B Buoy Shackle last?

A3: The service life of the hot-dip galvanized coating is typically 8–10 years (though this may vary depending on the specific operating environment), while specialized anti-corrosion coatings can last up to 10–15 years. With regular maintenance and upkeep during use, the service life of the coating can be further extended, thereby minimizing corrosion-related wear and tear.

Q4: What certifications are available for the Type B Buoy Shackle? How can I obtain the certification certificates?

A4: The Type B Buoy Shackle is available with certifications from major international classification societies, including CCS, BV, KR, DNV, ABS, NK, RINA, LR, and RS. Customers can specify their required certifications when placing an order; we will provide the corresponding certification certificates alongside the shipment upon the product's departure from our facility, ensuring full compliance with the customer's regulatory requirements.

Q5: How do I select the appropriate size of the Type B Buoy Shackle?

A5: When selecting a size, it is necessary to consider a combination of factors, including the diameter of the buoy chain, the mooring load requirements, and the operating environment. As a general rule, the diameter of the Type B Buoy Shackle should match the diameter of the buoy chain while simultaneously meeting the specific load-bearing requirements of the actual operation. If a client is unsure of the specific specifications, our technical staff can provide professional selection recommendations based on the usage scenarios and parameters provided by the client.
