Sucker Rod Centralizer

1.Sucker rod centralizer is a kind of downhole tools which is pumping well anti-abrasion, it is especially suitable for pumping well and directional well which above of sucker rod middle point,under the middle point of sucker rod , the rod body with nylon centralizer is works better.

The sucker rod moves up and down in the tubing, due to the elastic deformation of sucker rod, rod and oil tube wall is easy to make friction, ti makes sucker rod break off easily, sucker rod centralizer has strong flexibility, touched with the tubing wall can reduce the friction of rod and tube, and can be increase production life of pumping unit. The centralizer is connected with sucker rod , the outside diameter of centralizer is bigger than coupling outer diameter,so that can make the function of centralize. The centralizer is made of high strength wear-resistant material, and touched with the tubing to reduce the abrasion to achieve the purpose of anti-abrasion.
