5 Inch Bimetallic CD Pins – Weldable Insulation Fasteners for Industrial and Marine Applications

Bimetallic CD pins are high-performance insulation fasteners specifically engineered for industrial and commercial applications where reliable fixing is critical. As a type of CD weld insulation pin, these pins require installation using CD welding machines, providing a strong and permanent attachment of insulation materials to metal surfaces. Their dual-metal design ensures mechanical strength while minimizing corrosion risks, making them ideal for environments with high temperatures or exposure to moisture.

Designed with a steel pin for durability and an aluminum base for lightweight corrosion resistance, Bimetallic CD pins provide exceptional stability for insulation layers over time. They are compatible with a wide range of insulation materials, including fiberglass, mineral wool, rigid foam boards, and ceramic fiber, making them suitable for HVAC systems, industrial pipelines, tanks, and shipbuilding insulation projects.

Material Options & Advantages

• Steel Pin + Aluminum Base – Offers superior mechanical strength and corrosion resistance, while remaining lightweight for easier handling.

• Stainless Steel Pin Variants – Ideal for applications in highly humid or corrosive industrial environments.

• Copper-Plated Options – Provides enhanced durability for specialized insulation projects, including chemical and marine industries.

All Bimetallic CD pins are produced under strict quality control procedures, ensuring consistent dimensions, weldability, and long-term performance. The aluminum base is specifically designed for compatibility with CD welding machines, allowing rapid, secure installation in large-scale projects.

Applications of Bimetallic CD Pins

• HVAC Duct and Ventilation Insulation – Maintain thermal efficiency and airflow integrity.

• Industrial Wall, Roof, and Tank Insulation – Ensure insulation materials remain securely attached under high temperature and vibration.

• Power Plants and Energy Facilities – Reliable fastening of insulation in high-temperature boiler systems and pipelines.

• Petrochemical and Chemical Processing Plants – Resistant to corrosive chemicals and high-temperature fluids.

• Marine and Shipbuilding Insulation Systems – Ideal for ship engine rooms, decks, and industrial marine equipment insulation.

Using Bimetallic CD pins ensures that insulation layers remain firmly in place over time, reducing maintenance costs and preventing detachment caused by thermal expansion, vibration, or corrosion. The CD welding installation method guarantees a permanent and reliable bond, especially important in heavy-duty industrial projects and shipbuilding applications.

Installation and Performance

Installation of Bimetallic CD pins requires a CD welding machine, which provides precise and strong attachment to metal substrates. Once welded, the pins maintain their structural integrity even in extreme temperatures, vibrations, and harsh environmental conditions. This makes them highly suitable for long-term insulation applications in power plants, factories, and marine environments.
