CFST is slightly stronger in axial forces than metallic tubing is. Our prototype testing showed 240,000 lbs. before the tubing broke. Since it weighs only one-third of metal equivalent tubing, it is a much stronger downhole. Example: 10,000 feet of steel tubing weighs 92KLBS, and our tubing weighs only 30KLBS, so we would have ±62KLBS (92-30kLBS) more pulling force than metal tubing.
