Hat wire patent

The fatigue life of manganese phosphating wear-resistant coated steel wire rope is three to five times that of smooth steel wire rope, which is well received by users. In order to prevent counterfeit manganese phosphating wear-resistant coated steel wire rope from being bought, attention should be paid to identification. "Phosphate coated steel wire rope" is an invention patent in China, and its patent number can be found on the website of China National Intellectual Property Administration Patent Office and China Knowledge Network. There are many enterprises authorized by patents in China, and the patent number of "phosphate coated steel wire rope" is sprayed on the packaging wooden shaft of legally produced manganese phosphating wear-resistant steel wire rope. In addition, 15-40g/m2 manganese phosphating film is on the surface of "phosphating wire rope". Also known as manganese phosphating wear-resistant coated steel wire rope, therefore, detecting the weight of manganese phosphating film on the surface of share split steel wire is also the most reliable method to judge the authenticity of manganese phosphating wear-resistant coated steel wire rope. The phosphating film with weight less than 3g/m2 is not the genuine product of manganese phosphating wear-resistant coated steel wire rope. Manganese phosphating wear-resistant coated wire rope is an upgraded product of various smooth wire ropes, which belongs to backward technology and is being eliminated.
