Centralizer is a special tool used to centralize rod string and prevent friction between rod string and tubing in screw pump Wells. The cylindrical rotating centralizer produced by our company solves the friction problem of rod string and tubing very well. The centralizer can be fixed with bayonet and connected with thread buckle.
The operation relies on nylon centralizer and tubing contact to prevent friction between the rod and tubing, nylon centralizer can rotate, so that uniform wear. It can replace the worn nylon straightener without replacing the rod body, which can save the production cost.
