Name: Stud Link Anchor Chain
MOQ: 100 Meters
Package: Steel Pallet / Bundle
TOPONE supplies Stud Link Anchor Chains according to approved marine chain specifications, dimensional requirements, and applicable classification society rules.
ISO 1704:2022 specifies the shape, proportions, dimensions, and tolerances of stud-link anchor chain components. Relevant IACS requirements and vessel classification rules address anchoring equipment, material properties, manufacturing verification, and required load testing within their respective scopes.
Manufacturing operations may include steel preparation, chain link forming, flash butt welding, stud installation, calibration, heat treatment as required, and final dimensional inspection.
TOPONE CHAIN is the brand of Xintai Taida Mirso Co., LTD, a China-based manufacturer and supplier of industrial chains and lifting equipment.
The company's broader chain manufacturing facilities feature nine automated production lines, over 5,000 m² of manufacturing workshop space, and a published annual capacity of approximately 500,000 high-strength load chains.
These figures represent TOPONE's overall chain manufacturing operations rather than a separately verified production capacity for this particular anchor chain model.
TOPONE supports OEM and bulk supply requirements, including customized chain dimensions, shot lengths, surface finishes, identification markings, and matching anchoring components.
For marine projects, the company can coordinate technical drawing reviews, manufacturing requirements, inspection arrangements, and related accessory supply according to the confirmed order.
Stud link anchor chain testing must follow the applicable chain grade, approved manufacturing specification, and relevant classification society requirements.
Verification may include:
Material identification and chemical composition testing
Mechanical property verification
Link diameter, length, width, and dimensional tolerance inspection
Flash butt weld examination
Stud installation and calibration checks
Heat treatment verification where required
Proof-load testing of finished chain shots
Breaking-load testing of representative specimens
Product identification and traceability checks
Material certificates, inspection reports, and classification society witnessing or certification requirements should be specified when placing the order.
Product certification must be supported by the actual manufacturing and inspection records. Approval by a classification society must not be assumed unless it is documented for the supplied product.
TOPONE Stud Link Anchor Chains are suitable for properly specified marine anchoring applications, including:
Container Ships: Main anchor chain systems for cargo vessels.
Bulk Carriers: Vessel anchoring and anchor-handling arrangements.
Oil and Chemical Tankers: Marine anchor chain systems selected according to vessel requirements.
LNG and LPG Carriers: Approved anchoring systems requiring specified chain grades and sizes.
Offshore Support Vessels: Anchor deployment and retrieval in compatible anchoring systems.
Shipbuilding and Ship Repair: New vessel construction, replacement chain shots, and maintenance.
Port and Marine Facilities: Suitable project-specific anchoring applications.
Offshore Mooring Systems: Only where the product is specifically approved for the intended mooring design and loading conditions.
The selected anchor chain must match the vessel's windlass, chain wheel, chain locker, anchor connection, and applicable grade requirements.
At the anchor end, a compatible End Shackle may be used to connect the anchor to the specified chain or swivel forerunner arrangement.
Conventional ship anchor chains must not be substituted for offshore mooring chains without appropriate engineering verification.
Inspect stud link anchor chains according to the vessel's maintenance program and applicable classification society requirements.
Check for excessive link wear, corrosion, cracked welds, deformation, loose or damaged studs, abnormal elongation, and damaged connecting components.
Verify the condition of the anchor chain's connection fittings and its compatibility with the windlass chain wheel.
Remove damaged or nonconforming chain sections from service according to the applicable inspection and rejection criteria.
