API 11B Nylon sleeve rotating sucker rod centralizer
The sucker rod centralizer is a supporting tool designed to decrease the pumping energy loss, increase the pumping efficiency, prevent the eccentric wear of sucker rod and protect the tubing.
The sleeve made of nanomaterial is provided with advantages such as self-lubrication, wearability, low hardness, high strength, flexible actuation etc.
When the centralizer is used, connect it to the fray of sucker rod, with which the sucker rod is replaced to connect the rod string.
The rotatable centralizer centralizes the sucker rod automatically, up and down, left and right as the sucker rod rotates up and down, reduces the friction between the sucker rod and the tubing, improves the service life of the sucker rod and tubing.
