An anchor chain tensioner is a device used to maintain proper tension in anchor chains, ensuring stability and security. Anchor chains are heavy-duty chains that connect the anchor to the vessel, providing strength and durability. The tensioner helps prevent slack, reducing wear and improving anchoring performance.

Anchor Chain Tensioner:

- Size: Typically 12.5mm to 152mm (0.5" to 6") in diameter

- Material: High-strength steel (Grade 2, Grade 3, or equivalent)

- Operating Load: 5 to 500 tons, depending on application

- Viscosity: N/A (mechanical device, not fluid-dependent)

- Buoyancy: Negligible (submerged operation)

- Corrosion Resistance: Often galvanized or coated for marine environments

Anchor Chains:

- Size: 12.5mm to 152mm (0.5" to 6") common, larger for heavy-duty use

- Grade: Grade 2, Grade 3, or higher (e.g., U2, U3, R3, R4, R5 per ISO 1704)

- Material: High-tensile carbon steel or alloy steel

- Viscosity: N/A (solid metal construction)

- Buoyancy: Negative (sinks in water due to high density)

- Breaking Load: Varies by grade (e.g., Grade 3: 700-900 N/mm² tensile strength)

- Finish: Hot-dip galvanized or painted for corrosion resistance
