API 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 4.1.3 Lubricant Lubricants shall conform to ISO 4346. 4.2 Rope manufacture 4.2.1 General In stranded ropes, all the wire layers in a strand shall have the same direction of lay. The lay lengths of corresponding wire layers in strands of the same size, construction and strand layer shall be uniform. The core of a stranded rope, except for compacted (swaged) ropes, shall be designed (steel) or selected (fibre) so that in a new rope under no load there is clearance between outer strands. The rope ends shall be secured such that they are prevented from unlaying 4.2.2 Wire joints Diameters shall be continuous, but, for wires other than well-measuring wires, if joints are necessary in wires over 0,4 mm they shall have their ends joined by brazing or welding. For stranded ropes, the minimum distance between joints within one strand shall be 18 × rope diameter (d). For spiral ropes, the minimum distance between joints in any wire layer shall be 36 × diameter of the wire layer. Wires up to and including 0,4 mm may be joined by twisting or by ends being simply inserted into the strands’ formation. 4.2.3 Preformation and postformation Stranded ropes shall be preformed or postformed or both, unless specified otherwise by the purchaser. NOTE Some parallel-closed ropes and rotation-resistant ropes may be non-preformed. 4.2.4 Construction The rope construction shall be either one of those covered in Annex G or as stated by the manufacturer. The constructions of compacted strand ropes, compacted (swaged) ropes, large diameter (i.e. over 60 mm) stranded ropes and spiral ropes (i.e. spiral strand and full-locked coil) shall be stated by the manufacturer. Where only the rope class is specified by the purchaser, the construction supplied shall be stated by the manufacturer.
