Abstract
Methods for assembling fiberglass reinforced plastic sucker rods include transporting fiberglass reinforced plastic sucker rod sections from an off-site location to an assembly facility at or near a point of use, and transporting a sufficient number of metallic end fittings to connect respective ends of the plurality of sucker rod sections in series at the assembly facility. Systems for assembly of completed sucker rods from sucker rod sections transported from off-site location to or near a point of use. The systems may include a female threaded end component, collar and machine mount that allows completed sucker rods to be pull tested, and record load, peak load, and elongation during the pull test.
