In oilfield operation, pumping jack and PCP(Progressive Cavity Pumping) systems increase operational costs associated with rod&tubing friction and paraffin deposition in production tubing. Sunrise Petro has developed a series of rod guides which are also called rod centralizer that are molded directly onto the rod body to control this threat.
Friction between a single sucker rod and the production tubing inevitably leads to severe wear on both strings. This problem is amplified in deviated wells and in sections where the string is exposed to high compressive loads.
Sunrise Petro rod centralizer centers the rod column and guides it smoothly through the tubing, avoiding metal-to-metal contact and absorbing lateral loads that cause premature wear of couplings, rods, and tubing. So that users can expect their rod and tubing units to last longer.

Sunrise Petro rod guides are manufactured from different materials specifically selected to ensure their excellent performance and long life service, which are Polyamide 66, Poliphenylene Sulfide (PPS) and Polyphthalamide (PPA).
Sunrise Petro can supply API Sucker rod including the common sucker rod& pony rod, polished rod and sinker bar. Based on API Spec 11B and SY / T 5029 specifications, Sunrise Petro also developed a series of special sucker rods suitable for different well conditions, especially under high corrosion and high load conditions for oil well.
