Simple Analysis of Wire Rope Standard
2022-10-24
Wire rope refers to the rope made of twisted steel wires. The Steel Wire Rope plays the role of bearing load, and its performance is mainly determined by the steel wire. The steel wire is a round (or profiled) wire made of carbon steel or alloy steel by cold drawing or cold rolling. It has high strength and toughness, and its surface is treated according to different environmental conditions. Standards for some types of wire ropes, GB/T 20118-2006 Category of Wire Rope for General Purposes Product Name Executive Standard Specification Range (mm) Wire Rope GB 8918-2006 GB/T 20118-20061.2 ~ 60.00 Coarse Diameter Wire Rope GB/T 20067-2006 60.00 ~ 120.00 Multi strand Wire Rope GB 8918-2006 GB/T 20118-200612.00 ~ 60.00 Four strand Sector Strand Wire Rope GB 8918-2006 12.00 ~ 50.00 Triangular Strand Wire Rope GB 8918-2006 13.00 ~ 60.00 Elliptical Strand Wire Rope GB 8918-2006 40.00 ~ 60.00 Sealed Wire Rope GB/T 352-2002 16.00 ~ 75.00 Flat Steel Wire Rope for Balance GB/T 20119-2006 58 × 13~216 × 34 Steel wire rope for petroleum ANSI/API Spec 9A-2004SY517-9213.00 ~ 64.00 Wire rope with surface contact (compacted strand) GB/T 16269-1996Q/HLS018-200616.00 ~ 60.00 Galvanized Wire Rope for highway guardrail ASTM A 741-1998 19.00 ~ 25.00 Wire rope for electric shovel GB 8918-2006 36.00 ~ 65.00 Hot dip galvanized round strand wire rope for fishery SC 143-86 12.5 ~ 26.00 Wire rope Plastic Coated Wire Rope GB 8918-2006 12.00 ~ 70.00 Quality judgment standard: 1. Specific gravity. The diameter of wire rope is the same. The heavier the specific gravity is, the better the quality of wire rope is. 2. Wire rope core. The stronger the wire rope core is, the heavier the specific gravity is, the better the supporting force for the outer strand of the wire rope is, and the better the wire rope quality is. 3. Materials. The material is steel grade and strength. The higher the steel grade and the higher the strength, the better the quality of the wire rope. 4. The quality of the slightly loose rope after cutting is good, and the quality of the wire rope with relatively long lay length is better than that of the wire rope with short lay length. 5. The anti-corrosion capacity of 316 Stainless Steel Wire Rope is stronger than that of 306 Stainless Steel Wire Rope, 306 stainless steel wire rope is stronger than that of hot-dip galvanized wire rope, and hot-dip galvanized wire rope is better than that of galvanized wire rope; The quality of Nylon Coated Steel Wire Rope is better than that of PE Coated Steel Wire Rope, the quality of PE coated steel wire rope is better than that of PVC Coated Steel Wire Rope, and the anti-corrosion capacity of plastic coated steel wire rope is stronger than that of galvanized steel wire rope.
