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

Installation SystemInstallation SystemC-Tech has developed unique solutions to simplify the service aspect of coiled rod:

The X-celeratorTM rod deployment systemused with a variety of well servicing units to run or surface Pro-rod strings

The FirebladeTM welding systemField deployed system to build and repair Pro-Rod strings easily and conveniently
