At present, the varieties of wire ropes produced in China are as follows:
1. Phosphating coated steel wire rope (patented in China). After the steel wire is phosphatized by manganese series and zinc-manganese series, the wear resistance and corrosion resistance of the steel wire have all-round jumped, which greatly improves the fatigue life of the steel wire rope, and the fatigue life is 3-4 times that of the smooth steel wire rope with the same structure (under comparable conditions in the laboratory), far exceeding the imported steel wire rope. It is suggested that you do a fatigue life test. Phosphate coated steel wire rope is replacing all kinds of smooth steel wire rope. It can also be used instead of galvanized steel wire rope (corrosion resistance can be tested by salt spray test), with longer service life, lower unit use cost and better quality stability and reliability. According to the approximate price of wire rope market, the price of manganese phosphating coated wire rope is higher than that of smooth wire rope, and the service life extension is much higher than the price increase. Therefore, the daily average use cost of phosphating coated steel wire rope is only 30-45% of that of smooth steel wire rope, which is lower in use cost and better in cost performance.
2. Galvanized steel wire rope, including hot galvanizing and electro-galvanizing. Generally, the galvanized zinc layer is thick, while the galvanized zinc layer is thin.
3. Stainless steel wire rope, mainly made of 304 or 3 16 stainless steel, has excellent anticorrosion effect, but it is expensive.
4. Based on plastic-coated steel wire rope and carbon steel wire rope, the outer layer is coated with polyethylene, polypropylene or nylon.
5. Smooth steel wire rope with short service life will be completely eliminated by phosphating coated steel wire rope.
6. Steel wire rope for mooring in offshore engineering
7. Wire rope
