API SPEC 9A-2004 pdf download.Specification for Wire Rope ANSI/API Specification 9A Twenty-fifth Edition, February 2004 ISO 10425:2003, Steel wire ropes for the petroleum and natural gas industries—Minimum requirements and terms for acceptance.
1 Scope This International Standard specifies the minimum requirements and terms of acceptance for the manufacture and testing of steel wire ropes not exceeding rope grade 2160 for the petroleum and natural gas industries. Typical applications include tubing lines, rod hanger lines, sand lines, cable-tool drilling and clean out lines, cable tool casing lines, rotary drilling lines, winch lines, horse head pumping unit lines, torpedo lines, mast-raising lines, guideline tensioner lines, riser tensioner lines, mooring and anchor lines. Ropes for lifting slings and cranes, and wire for well-measuring and strand for well-servicing, are also included. The minimum breaking forces for the more common sizes, grades and constructions of stranded rope are given in tables. However, this International Standard does not restrict itself to the classes covered by those tables. Other types, such as ropes with compacted strands and compacted (swaged) ropes, may also conform with its requirements. The minimum breaking force values for these ropes are provided by the manufacturer. For information only, other tables present the minimum breaking forces for large diameter stranded and spiral ropes (i.e. spiral strand and locked coil), while approximate nominal length masses for the more common stranded rope constructions and large diameter stranded and spiral ropes are also given. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 2232:1990, Round drawn wire for general purpose non-alloy steel wire ropes and for large diameter steel wire ropes — Specifications ISO 4345, Steel wire ropes — Fibre main cores — Specification ISO 4346, Steel wire ropes for general purposes — Lubricants — Basic requirements ISO 6892, Metallic materials — Tensile testing at ambient temperature
3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 17893 apply. 4 Requirements 4.1 Material 4.1.1 Wire The wires for stranded ropes and well-servicing strand of carbon steel shall, before rope fabrication, conform to the diameter, tensile, torsion and, when applicable, zinc-coating requirements specified in Annex A. The methods of test for wires of tensile strength grades 1 370 N/mm 2 , 1 570 N/mm 2 , 1 770 N/mm 2 , 1 960 N/mm 2 and 2 160 N/mm 2 shall be in accordance with those given in ISO 2232. The methods of test for wires of tensile strength grades Levels 2, 3, 4 and 5 shall be in accordance with Annex B. For those ropes where a rope grade is applicable, the tensile strength grade of the wires shall be subject to the limits given in Table 1. NOTE The minimum breaking force values of those ropes of grades 1770, 1960 and 2160 as covered by the tables are calculated on the basis of rope grade and not individual wire tensile strength grades or levels.
For those ropes (e.g. larger diameter ropes) where a rope grade is not applicable, the tensile strength grades of the wires shall be one, or a combination, of those given in Annex A. All wires of the same nominal diameter in the same wire layer shall be of the same tensile strength grade. Well-measuring wire and wires used in the manufacture of well-servicing strand shall normally be of carbon steel but other materials (e.g. stainless steel) may be used. The purchaser should specify any particular material requirements. 4.1.2 Core Cores of stranded ropes shall normally be of steel or fibre, although other types, such as composites (e.g. steel plus fibres or plastics) or cores made of solid polymer, may also be supplied. The purchaser should specify the type of core.
