Three Major Advantages of Jiaolong Brand Buoy Ropes
This Jiaolong brand buoy rope is produced by Qingdao Huakai Ocean Technology Co., Ltd. (Hailiya Group). In late 2013, our company participated in the world's large-scale Western Pacific Ocean Strategic Pioneer Project, supporting the development and production of oceanographic research ropes with a total order of 200,000 meters.
The three major advantages of this Jiaolong brand buoy rope are:
10% higher strength compared to products from other manufacturers.
Two patented technologies for eye termination, ensuring the eye strength exceeds that of the main rope (unlike other manufacturers where eye strength is often weaker), outperforming imported ropes.
Continuous length of 5,000 meters without splices, ensuring consistent performance.
Previously, steel cables were used for oceanographic research to deploy instruments. However, steel cables have three critical weaknesses:
High density: When the survey length reaches 30,000 meters or more, the effective payload is consumed by the cable's own weight. At 10,000 meters, the self-weight may even cause the steel cable to break.
Twisted structure: When lowered into the seabed, steel cables tend to rotate and twist. There have been major research accidents where twisting caused breakage, resulting in lost instruments.
Susceptibility to seawater corrosion: Prolonged exposure to seawater weakens steel cables, leading to breakage, loss of instruments, failed experiments, and loss of state assets.
In contrast, the Jiaolong brand buoy rope developed by our company has a density lower than seawater, features a bidirectional braided structure for effective torque balance, and uses materials resistant to seawater corrosion.
The three weaknesses of steel cables are effectively addressed by our product. Additionally, the breaking strength of our rope is 2-5 times higher than steel cables of the same diameter. It incorporates five intellectual properties in eye design, rope splicing, sheath structure, and seamless braiding.
Qingdao Huakai Ocean Technology Co., Ltd. (Hailiya Group) independently developed China's early rope finishing equipment. This equipment utilizes the principle of cold and hot stretching of polymer materials to enhance rope strength, reduce elongation, and apply coatings for improved functionality, including corrosion resistance, waterproofing, and anti-biofouling. This expands the application scope and service life of the ropes. Depending on the environment, submersible buoy ropes can be made from low-elongation Kevlar or high-strength, lightweight Dyneema materials.
The Jiaolong brand buoy rope is available in various specifications such as 6mm, 8mm, 10mm, and 12mm, depending on the load requirements.
Our Jiaolong brand buoy ropes have been deployed on the seabed for 1-2 years without any issues. They have been safely recovered after being submerged at depths of 6,000-7,000 meters for 1-2 years. After over a decade of use and validation by marine research institutions such as the Chinese Academy of Sciences, the Ministry of Natural Resources, and China State Shipbuilding Corporation, the product's performance and technology have proven mature and reliable. Customers can purchase and use it with confidence.
