Product Description
JX Petro Polished Rod Spray Metal Polish rod dimensions conform to API Specification 11B, latest edition, and AISI Steel Products Manual.
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.
- High tensile strength.
- Can be used with sucker rod and hollow sucker rod.
- Corrosion resistant.
- Solid and hollow structure for different requirements.
