2.2 Polish Rod
Introduction
JX Petro Polished Rod dimensions conform to API Specification 11B, latest edition, and AISI Steel Products Manual. There are two types of polish rod by end shape: regular grade D polished rod and end upsetting polished rod. The regular grade D polished rods are connected by the polished rod coupling, and the end upsetting polished rods are connected to the sucker rod directly for usage.
Polished Rods are furnished with cold-formed, fully rolled threads to provide additional strength and fatigue resistance. The cold-formed, fully rolled pin thread is produced by completely cold-forming (reshaping) the steel fibers so they follow the contour (shape) of the thread. The thread surface that results from fully rolled threads improves its resistance to corrosion and reduces abrasion within the thread.
The work-hardened flank provides increased surface tensile, yield and shear strength. Due to the pressure deformation, a residual compressive stress system builds up at the thread root, which counteracts tensile loading. When compared to cut or burnished threads, the load capacity and corrosion and fatigue resistance of the rolled thread is significantly increased.
