The structural damage of Nylon coated wire rope is the primary factor affecting the actual performance and service life of the wire rope. Careful analysis of the actual operating conditions, scientific and rational selection of the wire rope structure is the basis for improving the performance and life of the wire rope. During oil operations or mine hoisting, the underground part is free to rotate, and the wire rope is constantly subjected to alternating tension and pressure loads, so the wire rope is constantly tightened and loosened, the resistance of the wellhead part, the friction in the well and the deformation of the wire rope itself. It will make the lay length of the wire rope continuously elongated, which is actually a process in which the wire rope is continuously untwisted.
Uneven Nylon coated wire rope core exposure on the reel occurs after the wire rope is untwisted, which is inevitable.
The occurrence of the above problems does not mean that Nylon coated wire rope has manufacturing problems, but the result of the combination of the wire rope structure and the particularity of the operating environment, which is not suitable for this working condition. The 6-strand steel wire rope of ordinary structure has the ability of rotation and can hang freely in long distances, so the self-weight of the selected steel wire rope has to be considered, and the Nylon coated wire rope must have the ability of "anti-rotation".
The unreasonable choice of Nylon coated wire rope structure and the special operation method are the reasons for this kind of damage, and it has been confirmed.
