As a reliable supplier of 3LPP coated pipe, we supply high-performance three-layer polypropylene anti-corrosion steel pipes for global high-temperature pipeline projects. The 3LPP coating system is composed of epoxy primer, copolymer adhesive and polypropylene top layer, offering outstanding mechanical protection and chemical resistance. Compared with 3LPE coating, it can withstand higher operating temperature, making it suitable for offshore, geothermal and high-temperature oil & gas working conditions. Our 3LPP coated pipes are produced to DIN 30678 standard, with customizable sizes and wall thickness. Supported by strict quality control and rich export experience, we have delivered many high-temperature pipeline projects for clients across the Middle East, Africa and Latin America.
