| description | A compacted strand special wire rope for petroleum drilling is composed of 6 outer strands and 1 steel core strand, and is characterized in that the outer strands are spirally twisted around the steel core strand, the outer strands are compacted and formed through rolling or die drawing, the outer strands are circular. Each outer strand is composed of 19-26 steel wire strands, the structure of outer strand includes that 2-3 layers of steel wires are entwisted on the periphery of 1 central steel wire 6, the 2-3 layers of steel wires respectively include an outer layer steel wire, a secondary outer layer steel wire, a filling steel wire or an inner layer steel wire. The steel core strand structure is 6*7-1*7 steel wires. The special wire rope has good abrasion resistance, increases metal fill factor and integral braking force value, has high carrying capacity and improves structural stability and anti-impact performance. The abrasion resistance and service life of the wire rope are improved so that the compacte |
