This is hight strength combination rope. This kind of perfect combination and construction makes it lower stretch. Widely used in morden offshore ships. Rope in use process, such as found that: 1. The strand rupture (2) the decrease of the rope diameter value is greater than 10%. 3. The structure of the terminal has a huge damage or wear. The above three conditions please replace the ropes to prevent safety accidents in a timely manner.
Comparison of several materials of Marine cables:
1.Polypropylene filament yarn is widely used in ships because its buoyancy is easy to operate and is favored by the crew, and is the most common among cables.
2.Polyester filament is stronger than polypropylene filament, and it is very smooth. It can effectively prevent wear and tear. The disadvantages are large and not easy to operate.
3.Nylon filament has the advantages of polyester filament, and the strength is higher than that of polypropylene filament, polyester filament. Because it can prevent static electricity so often used in chemical tanker, liquefied gas tanker, tanker and so on.
3.High polymer polyethylene belongs to high-grade material, used to be used in flak jacket, because of its strong tensile strength, used in the cable industry. Because of its light weight and environmental protection, it is the best substitute for steel wire rope.
