Duct Pins M3 Stud Welding Insulation Pins Used in Marine and Building System
Product Description
Marine studs are protrusions fixed on the hull of a ship, usually made of materials such as copper, aluminum, steel, etc. Its main function is to reduce damage to the ship's hull when it collides with other objects during docking, navigation, or travel, and to improve the stability and traction of the ship.
1. Protecting the hull of the ship
Marine collision studs can protect the hull of a ship from damage caused by external collisions, reducing wear and corrosion of the hull.
2. Improve stability and traction
The raised design of the collision nail can increase the surface area of the ship, increase the contact area between the ship and water, and thus improve the stability and traction of the ship.
3. Reduce water resistance
Collisions can improve the shape of water flow, thereby reducing water resistance and the risk of ship sinking, and enhancing the efficiency of ship operation.
Product Features
Common materials include low-carbon steel (such as Q195) and aluminum alloy, among which aluminum studs are lighter in weight and have better corrosion resistance than stainless steel, making them suitable for aluminum structures in ships.
Surface treatment is mostly copper plating or zinc plating. Copper plating technology improves conductivity and welding firmness, and its anti-corrosion performance is better than ordinary galvanized steel nails.
It is usually made by riveting galvanized carbon steel wire and galvanized sheet, with 6 evenly distributed holes designed to facilitate adhesive penetration and fixation.
The length can be adjusted according to the thickness of the insulation material, for example, the extension length needs to exceed the thickness of the rock wool by 5 millimeters to ensure the fixing effect.
