Resin soaked fiberglass strands are applied to abrasively cleaned steel pipe to increase the hoop stress. Steel pipe that is abrasively cleaned is preheated and a primer coat is applied. Fiberglass strands that are soaked with heated resin are then applied in a helical method to the pipe to induce an accelerated cure of the resin. Followed by a polyethylene wrap to protect the ouside of the composite. Allowing the coated pipe to be driven over a conveyor line. This process is continuous in which the steel pipe is wrapped from end to end, on pipe that is connected with a come-along (steel or plastic).
