Steel wire ropes for the petroleum and natural gas industries — Minimum requirements and terms of acceptance
This document 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. Wire 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 document does not restrict itself to the classes covered by those tables. Other types can also conform with its requirements. The minimum breaking force values for these wire 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.
