Tubing centralizer is basically composed of coupling, centralizer, mandrel, spring plate and friction block. It is mainly used for tubing in inclined wells and vertical wells with high inclination. During operation, the centralizer is connected to both ends of the packer to ensure the co-axiality of the tubing, reduce the eccentric wear phenomenon and friction damage of the well wall to the packer rubber tube. Meanwhile, the service life of the packer is prolonged to ensure the normal and orderly construction.

This Model is drifted with the corresponding API tubing drift size.

NOTE: Additional size, weight, end connection etc. are also available on request.
