Standard
The mechanical performance of hollow sucker rod from our company reaches the SY/T5550-2006 “Hollow sucker rod" D level standard.
Property and Application
Hollow sucker rod is a special product used for mining "high condensation, high viscosity, high wax" crude oil, and it is a rod, of which the rod head and couplings, through friction welding, are welded to seamless steel tube ends or directly in the direct rammer of both ends of seamless steel tube, all functions are realized through the inner channel of the hollow sucker rod which is formed within the tubular column. Hollow sucker rod can be used for:
(1) injecting heat carrier oil extraction device;
(2) the hollow sucker rod electrical heating device;
(3) the oil extraction device without oil tube;
(4) and driving screw pump underground with its characteristics of high stiffness, strong bearing ability to twist.
