The production of studless chains involves several critical steps to ensure strength, durability, and compliance with international standards. Below is an overview of the typical manufacturing process:
High-quality steel bars are selected based on chemical composition and mechanical properties. The steel is then cut into appropriate lengths and heated uniformly to facilitate bending and forming.
Automated machines bend the heated steel into J and C shapes, linking each segment to form a continuous chain. This precision forming ensures uniformity and reduces defects.
Each link is welded using flash butt welding, a process that produces a strong, seamless joint with minimal heat-affected zones. This welding method is critical for the chain's overall strength.
The welded chain undergoes heat treatment processes such as quenching and tempering to enhance tensile strength, toughness, and fatigue resistance. This step is vital for chains used in harsh marine environments.
Chains are polished to remove surface imperfections and coated with anti-corrosion layers, such as galvanization or specialized marine paints, to extend service life.
Each batch undergoes rigorous testing, including proof load tests, break load tests, and mechanical property evaluations. Non-destructive testing methods like ultrasonic inspection may also be employed to detect internal flaws.
After passing all quality checks, chains are marked with identification codes, painted if necessary, and packaged carefully to prevent damage during transportation.
This meticulous manufacturing process ensures that studless chains meet or exceed international standards such as ISO and classification society requirements, providing customers with reliable, long-lasting marine anchoring solutions.
China's studless chain manufacturers are at the cutting edge of marine technology, offering reliable, high-strength solutions for global maritime and offshore industries.
