Import 8x19s-Iwrc — Buy in Bulk from Supplier in China

The 8x19s-iwrc steel wire rope from China Petroleum Xianyang Bomco Steel Tube & Wire Rope Co., Ltd. South Central Branch is a compacted strand construction with eight outer strands of 19 wires each, built around an independent wire rope core. The source data confirms compliance with GB 8919 and API 9A standards, with the iwrc design providing superior crush resistance compared to fibre-core alternatives. Tensile strength and fatigue resistance are cited as primary performance characteristics, though exact breaking load figures are not stated in the listing and should be requested from the supplier with certificate reference.

The 8x19s construction offers a practical balance between flexibility and wear resistance, with the Seale pattern (larger outer wires over smaller inner wires) distributing contact stress across strand surfaces. IWRC construction typically adds 7.5% to 10% to the rope's breaking strength over fibre core equivalents, while maintaining dimensional stability under multi-layer drum winding. The compacted strand geometry reduces the rope's nominal diameter relative to standard round-strand equivalents, enabling higher line pulls on existing sheave and drum configurations. Standard material is drawn patented carbon steel wire, with zinc coating options typical for corrosive environments.

Primary buyers include crane fleet operators, offshore platform rigging contractors, mining hoist maintenance teams, and heavy civil engineering project procurement officers. The rope serves as running rope in tower cranes, luffing ropes in mobile cranes, and pendant lines in offshore supply vessels. Buyers should confirm the exact diameter range stocked, available reel lengths, and whether left or right regular lay is standard. The supplier's South Central Branch location in Changsha, Hunan Province, positions it for inland Chinese manufacturing and Yangtze River basin port access.

China Petroleum Xianyang Bomco Steel Tube & Wire Rope Co., Ltd. South Central Branch operates from Block 3 C Zone Mechanical Product Market, Yuhua District, Changsha, Hunan Province, China. The supplier is classified as an imported-tier, harbor-trust listing with a recorded response rate of 0.00% and zero logged average response hours. This profile indicates the listing is present on the platform but does not demonstrate active sales engagement or verified transaction history through this specific branch office.

The company name ties it to the Bomco (Baoji Oilfield Machinery) corporate network, a state-affiliated petroleum equipment manufacturing group with historical strength in oilfield tubular products and wire rope supply to CNPC operations. The South Central Branch designation suggests regional distribution rather than primary manufacturing. The listing does not state factory ownership, production capacity, in-house testing facilities, or ISO 9001 certification held directly by this entity. Buyers should verify whether this branch holds authorised distribution rights from the Xianyang parent plant, and whether certificates of conformity are issued in the branch name or the manufacturer's name.
