Sucker rods


Polished rod

ELKAM company supplies polished rods with nominal diameters 28, 32, 38 and 42 mm with the length from 2.5 to 8 meters. Also we supply hollow polished rods with nominal diameters 32, 38 and 42 mm with the length from 3.5 to 8 meters. To make the surface of our rods wear and corrosion resistant and as the result to increase their runlife our company applies unique technology of flame coating with hard-alloy materials.

Sucker rod

Sucker rods are applied to be round metal stem with hot shaped connecting ends. ELKAM supplies sucker rods manufactured in accordance with API-11B standard with the diameters 16, 19, 22 and 25 mm of K, C, D and D spec. grades. We developed a unique product – sucker rod ShNK-29 of D grade with coupling diameter 54 mm which can be applied with 2 7/8” tubing by contrast with standard sucker rod 29. It allows to produce oil from the depth over 2500 meters.

Fiberglass sucker rod

Fiberglass sucker rod has a variety of advantages in comparison with steel sucker rod such as increase of pump setting depth up to 2500 meters, decrease of horsehead maximum load when rods string moves upwards and decrease of ARWD influence on rods string. Line of fiberglass sucker rods supplied by ELKAM includes rods with nominal diameter from 19 to 29 mm of K, C and D grades, manufactured in accordance with API-11B standard.

Hollow sucker rod (HSR)

Hollow sucker rods are designed to transfer driving energy from the surface drive to the plunger of submersible pump or PCP rotor. Also they are applied for simultaneous oil production, washover operations of tubing string from ARWD and ice, injection of chemicals and steam during bottom-hole formation zone treatment. Our company manufactures and supplies 5/8", 3/4", 7/8" and 1" hollow sucker rods from 0.5 to 8 meters.

Flexible cable rod

Flexible cable rod equipment set is used for SRP operation in side-holes of small diameter, inclined and highly deviated wells (up to 90°). Equipment set consists of sucker rods string, tubing string, flexible cable rod, crossover coupling, specialized SPeaR pump and slot filter. Application of cable rod at the place of maximum inclination angle allows avoiding wearing of tubing string by sucker rod couplings due to decrease of friction between rods and tubing.
