What this video covers
Regalvanizing anchor chain and anchors extends their service life by approximately 7 to 10 years by applying a sacrificial zinc coating that prevents steel corrosion.0:36 Tropical waters accelerate oxidation, making regular maintenance essential for safety.0:31 When professional galvanizing is unavailable, applying water-repellent grease, such as lanolin, provides a temporary barrier against moisture and oxygen.1:25 The professional galvanizing process begins with acid pickling or abrasive blasting to remove rust and organic material.3:14 The cleaned components are then dipped in a flux solution of zinc ammonium chloride before immersion in a molten zinc bath heated to 450 degrees Celsius.4:08 This creates a molecular bond between the zinc and the steel.4:53 After cooling, the chain should be inspected for uniform coating thickness to ensure it maintains its original breaking load capacity.8:13 Marking the chain at specific intervals assists with accurate scope deployment during anchoring.11:01 Regular inspection of chain links for thinning at the welds confirms the structural integrity of the ground tackle.10:39
