Heavy-Duty Copper Welders Pin – Reliable Fastening for Marine Insulation

Welders pins are high-quality fastening components designed for securely attaching insulation materials to metal surfaces in demanding industrial and marine applications. Installed using CD or stud welding machines, these pins provide strong, permanent attachment, ensuring insulation remains stable even under vibration, high temperatures, or corrosive environments.

Once welded in place, insulation is mounted on the pin and held securely with a self-locking washer, maintaining long-term durability and thermal efficiency. These pins are commonly used in shipbuilding, HVAC systems, industrial pipelines, power plants, and other heavy-duty insulation projects where reliable performance is critical.

Material Options & Advantages

Our welders pins are available in a variety of premium materials to meet specific project requirements:

• Copper-Plated Steel – Provides excellent corrosion resistance, especially for marine applications

• Zinc-Plated Steel – Cost-effective option for general industrial insulation

• Stainless Steel 304 / 316 – Offers superior durability and corrosion resistance for demanding environments

• Custom Materials – Available upon request for specialized projects

Every pin is produced under strict quality control to ensure consistent dimensions, weldability, and holding strength. Custom lengths, diameters, and base types can be tailored to meet unique project requirements.

Specifications

• Pin length should exceed insulation thickness for secure self-locking washer installation

• Standard nail point, with blunt end available as a special order

• Compatible with all standard CD and stud welding machines

Additional Notes:
These welders pins are engineered to provide maximum performance in industrial and marine environments. Proper welding ensures strong attachment, reduces insulation detachment risk, and maintains long-term stability under vibration, thermal cycling, or corrosive conditions. Custom base types and lengths are available to accommodate specific insulation systems.

Applications

• Marine insulation, including engine rooms and decks

• Industrial wall, roof, and tank insulation

• HVAC systems for industrial and marine facilities

• Power plants, petrochemical, and chemical processing insulation

• High-temperature or vibration-prone industrial equipment

By using welders pins, insulation layers remain firmly attached, preserving structural integrity and reducing maintenance needs. Their compatibility with CD and stud welding machines makes them ideal for large-scale industrial and marine insulation projects.
