19、s (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations,
20、 governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO
21、/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the m
22、ember bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10425 was prepared by Technical Committee ISO/TC 105, Steel wire rop
23、es. BSISO10425:2003IS:52401 O3002(E) I SO 3002 All irhgts seredevr vIntroduction This International Standard is based upon API 1)Specification 9A, 24th edition, June 1995. This International Standard was developed in response to worldwide demand for minimum specifications for ropes for use on equipm
24、ent and machinery associated with the petroleum and natural gas industries. In recognition of equipment already in use and originally designed to accommodate rope sizes (nominal rope diameters) based on “English” units, some of the more common “converted SI unit” sizes have also been included. In ad
25、dition, and in recognition of equipment already in use and designed to operate with ropes having specific rope grades (e.g. IPS), based on “US” wire levels, these grades have also been included in order to give prominence to the required minimum values of breaking force associated with these grades
26、and help to ensure that existing design safety levels are maintained. Having due regard to size and breaking force for a particular rope class or construction, in some cases it is possible to safely substitute a US customary size and grade with one based solely on SI units and grade, and vice-versa.
27、 To assist in this process, this International Standard gives a size range for each nominal rope diameter and equivalent minimum breaking forces (converted from US customary units) for comparison, although it is recommended that the equipment designer or rope manufacturer (or other competent person)
28、 is consulted prior to ordering a substitute rope. It should also be noted that a particular design of rope may be capable of offering a higher breaking force value than the one specified either in the relevant table in this International Standard or by the manufacturer in his catalogue. In such cas
29、es, a higher minimum breaking force value (or actual breaking force value if the rope has already been manufactured and tested) may be provided by the manufacturer before an order is placed. Designers of new equipment are encouraged to select ropes having the preferred SI units and grades. To comple
30、ment this International Standard, ISO 17893, covering definitions, designation and classification, has been prepared. 1) American Petroleum Institute, 1220 L Street NW, Washington D.C. 20005, USA.

31、vr 1Steel wire ropes for the petroleum and natural gas industries Minimum requirements and terms of 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 petr
32、oleum 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
33、, 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 In
34、ternational 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 inform
35、ation 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 Norma

40、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
41、N/mm 2 , 1 770 N/mm 2 , 1 960 N/mm 2and 2 160 N/mm 2shall 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
42、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.

43、trength grades Rope grade Wire tensile strength grades N/mm 21770 1 570 or Level 2 to 1 960 or Level 4 1960 1 770 or Level 3 to 2 160 or Level 5 2160 1 960 or Level 4 to 2 160 or Level 5 IPS Level 2 or 1 570 to Level 4 or 1 960 EIP Level 3 or 1 770 to Level 5 or 2 160 EEIP Level 4 or 1 960 to Level
44、5 or 2 160 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.
45、 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 o
46、r 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. BSISO10425:2003IS:52401 O3002(E) I SO 3002 All irhgts seredevr 3Fibre cores shall conform to ISO 4345. The fibre
47、 cores for single-layer stranded ropes larger than 8 mm diameter shall be doubly closed (i.e. from yarn into strand and from strand into rope). Natural fibre cores shall be treated with an impregnating compound to inhibit rotting and decay. Steel cores shall be either an independent wire rope (IWRC)
48、 or wire strand (WSC). Steel cores of single-layer stranded ropes larger than 12 mm diameter shall be an independent wire rope (IWRC), unless specified otherwise. 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 stra
49、nd 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.
