Technical SpecificationsTechnical Specifications
Rod is manufactured using 1536 carbon steel, 4120 alloy and/or 4330 alloyThe Alloys contain increased chromium, molybdenum and nickel content for added corrosion resistance13/16”, 7/8”, 1” and 1 1/8” available For rotary applications:
1” rod torque range from 970 to 1240 ft/lbs1 1/8” rod torque range from 1380 to 1770 ft/lbs

Benefits of Coiled RodBenefits of Coiled Rod
Increased ProductionNo rod coupling-piston effect
Reducing fall rate problems and increasing overtravelLarger rod in tubing capabilitySlim hole applications
Reduced Maintenance CostsReduces mechanical tubing wearIncreases rod service lifeOnly two threaded connectionsCan reduce paraffin buildup

Rod/Tubing WearRod/Tubing Wear
Pumping fluid, especially with high water cuts, with abrasives can result in accelerated wear on the rod and tubing
Concentrated at the rod couplingsSolution to rod/tubing wear issues is to remove the concentrated contact points
