Measures to prevent the failure of sucker rod centralizer

Prevention rod centralizer manufacturer tells about the repair of old sucker rods

A large number of sucker rods need to be replaced every year in various oilfields of our country.Most of them can be repaired and reused except that they cannot be repaired because of serious eccentric wear and corrosion and bending deformation.The old sucker rod repair can not only realize the repeated use of the old sucker rod,save a lot of resources,but also reduce the production cost,improve the overall economic benefit of the oilfield,and bring considerable economic benefit for the manufacturer.Here is a guide from rod centralizer manufacturers on how to repair old rods for reuse.
At present,the domestic repair process is of the old rod after surface cleaning,straightening,surface quenching process,such as in extent,has realized the old repair and utilization of the sucker rod,but its limitations and shortcomings,such as the eccentric wear,corrosion will not be able to repair the old sucker rod,it greatly reduces the old rod repair rate.At the same time,because the old sucker rod is immersed in the well fluid for a long time,the harmful corrosive gas that penetrates into the lattice of the rod body cannot be precipitated,which inevitably accelerates the corrosion rate of the rod body during the service process,thus reducing the service life of the rod after repair.In addition,it can not improve the internal structure of sucker rod,which can not eliminate metal fatigue,and also greatly reduce the service life of sucker rod.
