High quality spiral steel pipe, ERW steel pipe, seamless steel pipe coated material, anti-corrosion pipe Three Polypropylene(3LPP),two Polypropylene (2LPP) pipe coatings for oil and gas pipes.
3LPP System is a multilayer coating composed of three functional components. This anti-corrosion system consists of a high performance fusion bonded epoxy (FBE) followed by a copolymer adhesive and an outer layer of polypropylene which provides the toughest, most durable pipe coating solution available. 3LPP Systems provide excellent pipeline protection for small and large diameter pipelines with high operating temperatures.
