Advantages:

1. Super-strength spring steel is applied to centralize casing in wellbore,and improve cementing quality.

2. Can be unfolded and stacked faltly, saving storage and transportation cost.

3. Non-welded, pressed by punching, high strength.

4. Easy-and-convenient to use.

5. Full rage of sizes (4″×5-7/8″, 4-1/2″×6-1/8″, 5″×61/2″, 5-1/2″×8-1/2″, 7″×8-1/2″, 7-5/8″×9-1/2″ , 8-5/8″×10-5/8″, 9-5/8″×12-1/4″, 10-3/4″×14-3/4″, 13-3/8″×17-1/2″, 16″×20″, 20″×26″, ect.) could meet customs requet.
