Marine non-linking，open link,Stud less boat anchor chain is a marine equipment made by welding elliptical anchor chain rings without supports. This boat anchor chain is processed into shape using the flash welding technique with CM490 material steel, and it has high strength and corrosion resistance.
Structural Characteristics of Marine non-linking，open link,Stud less boat anchor chain:
Marine non-linking，open link,Stud less boat anchor chain adopts an elliptical chain ring structure without supports, and is formed into a continuous chain through precise welding. Compared with the traditional studlink anchor chain, the Marine non-linking，open link,Stud less boat anchor chain omits the berthing plate structure, allowing the chain length to be freely adjusted, which can meet the requirements of different water depths and ship specifications, especially showing higher flexibility in deep-water operations.
The elliptical ring design reduces water resistance and minimizes the swinging amplitude of the anchor chain when used in deep water areas.
Application scenarios and performance parameters of Marine non-linking，open link,Stud less boat anchor chain:
The Marine non-linking，open link,Stud less boat anchor chain is mainly used in deep-water anchoring systems of bulk carriers and oil tankers of 50,000 tons and above, and is applicable to sea areas with water depths ranging from 50 to 200 meters. And using the galvanized accessories can extendMarine non-linking，open link,Stud less boat anchor chain service life.

Q1: Does stud less marine boat anchor chain strength meet safety requirements?
A: Class-certified stud less boat chains deliver breaking loads that strictly comply with regulatory requirements, ensuring full safety compliance for small to medium vessels.
Q2: High-strength steel vs. stainless steel?
A: Depends on budget and environment:
Steel: Cost-effective solution with galvanizing (mainstream choice)
Stainless steel: Superior corrosion resistance, extended service life, near-zero maintenance – ideal for special vessels/harsh environments (e.g., chemical tankers, desalination plants)
Q3: Why are class certificates critical?
A: Class certificates are proof of compliance with international/national safety codes (e.g., SOLAS). Without certifications the boat can’t pass the vessel inspections.
Q4: What tension load can your chains withstand?
A: Breaking load varies by Diameter (36-162mm),Material grade (R3/R4/etc.)and Manufacturing standard.We provide chains with certified breaking load data for every specification.
Q5: When to replace anchor chains?
A: Conduct regular inspections for:
① Wear: Diameter reduction exceeding class limits
② Deformation: Bent/twisted links
③ Cracks: Surface defects
④ stud damage: Loose/welding failures
⑤ Severe corrosion: Especially non-stainless chains
