API SPEC 11B-2010 pdf download.Specification for Sucker Rods, Polished Rods and Liners, Couplings, Sinker Bars, Polished Rod Clamps, Stuffing Boxes, and Pumping Tees.
3 Terms and Definitions For the purpose of this document the following terms and definitions apply. For quality system related terms used in this Specification and not defined below, see API Q1. 3.1 batch lots processing Material processed in a machine in defined quantities or volumes. 3.2 body The length of the rod located between the upset transitions, see Figure A.1. 3.3 continuous processing Material flowing steadily through the processing equipment in an undefined quantity or volume. 3.4 couplings Internally threaded components used to connect sucker rods, sinker bars, pony rods, or polished rods from the surface to the subsurface pump where both threads are of the same size and type. 3.5 dent Local change in surface contour caused by mechanical impact, but not accompanied by a loss of metal.
3.6 discontinuity Interruption in the normal physical structure or configuration such as cracks, laps, seams, pits, and laminations. 3.7 end shear crack Mill shear discontinuity, which shows as a crack across the pin end face. 3.8 fiber reinforced plastic (FRP) sucker rod Sucker rod typically manufactured in three pieces and assembled by a process that provides connection of two metal end fittings connected to a non-metallic fiber reinforced plastic rod. 3.9 forging lap Discontinuity produced when two metal surfaces fold against each other without metallurgical bonding. 3.10 forging overfill Excessive metal stocking of the forging die resulting in a forging lap. 3.11 independent calibration agency Organization providing calibration services that is independent of the manufacturer. 3.12 kink Short, tight bend. 3.13 longitudinal Direction along the long axis of the rod. 3.14 longitudinal discontinuity Discontinuity where the orientation of the long axis of the discontinuity is within plus or minus 60 ° from the longitudinal direction and is longer in the longitudinal direction than in the transverse direction. 3.15 micro-crack Crack undetectable by unaided visual inspection. 3.16 nick Local change in surface contour accompanied by a loss in metal caused by mechanical impact. 3.17 on-off tools Two-piece, reusable tool that provides a means of remotely connecting and disconnecting the sucker rods at or above the sucker rod pump. 3.18 pit Small, regular or irregular crater where the major (longest) diameter is not more than twice the minor (shortest) diameter.
3.20 polished rod clamp Device attached to the polished rod, which in conjunction with the pumping unit carrier bar secures a polished rod to the surface pumping unit. 3.21 polished rod liner A hard, sprayed metal, thin walled tube that is installed over and seals against the polished rod and stuffing box internal seals. 3.22 pony rod Sucker rod of reduced length used to place the pump at the desired depth in the well. 3.23 pull back Discontinuity in the sprayed metal coating where the coating does not extend to its intended surface coverage. 3.24 pumping tee Tubing fitting assembled to the top of a pumping well and below a stuffing box, designed to discharge production fluids through a side opening connected to a flow line. 3.25 qualified person Personnel with characteristics or abilities, gained through training and/or experience as measured against established requirements, standards or tests, that enable the individual to perform a required function. 3.26 reference master gauge Gauge which has been certified by an independent calibration agency and is used for verification and calibration of working gauges. 3.27 rod guides Metallic or polymeric materials attached to the sucker rod string to centralize the sucker rods and reduce sucker rod and tubing wear and/or reduce paraffin build-up. 3.28 rolled-in-scale Surface discontinuity caused by scale (metal oxide) formed during a previous heating which has not been removed prior to bar rolling or upset forging. 3.29 rolling lap Longitudinal surface discontinuity that can have the appearance of a seam, caused during rolling, fins, or sharp corners being folded over and then rolled into the bar surface without metallurgical bonding.
