Certified Flash Butt-Welded U2/U3 Studlink Mooring Anchor Chain

The main materials are hot-rolled anchor steel (CM490, CM690) which offer high strength and durability, suitable for heavy-duty applications. Stainless steel (316, 316L) is also used, especially in environments where corrosion resistance is crucial, as it can withstand the harsh marine environment with its excellent resistance to rust and chemical corrosion.

The diameter of the chain should be selected based on the size and weight of your boat. Larger and heavier ships require thicker chains to handle the greater loads. As a general rule, the larger the displacement of the ship, the higher the tensile force the anchor chain needs to withstand, thus requiring a larger diameter chain. You can also consult the ship's construction standards or marine equipment experts for more accurate advice.

The stud increases the strength of the link by evenly distributing the load. It prevents link elongation under heavy stress, reduces the risk of link twisting, which could lead to tangling, and also adds some extra weight to the chain. All these functions contribute to the overall reliability and performance of the anchor chain during anchoring operations.

Yes, especially higher-grade studlink anchor chains (such as grade 3) that have better mechanical properties due to more rigorous heat treatment. They can withstand higher loads and are more resistant to fatigue. However, it is still important to ensure that the chain is properly maintained and inspected regularly, as extreme weather can put additional stress on the chain. In very cold conditions, for example, some materials may become more brittle, so it is crucial to choose the right material

Quality is ensured through compliance with international standards like ISO 1704:2008. Manufacturers also obtain certifications from major classification societies such as DNV, GL, ABS, LRS, RINA, BV, NK, KR, IRS, RS. These certifications are based on strict testing procedures, including tensile strength testing, fatigue testing, and dimensional inspections. Additionally, the unique identification number on each chain allows for traceability, ensuring that any quality issues can be traced back t
