Abstract: A three layer PVDF coating system is provided for oil or gas pipe. The system comprises a steel pipe, an epoxy layer, for example, made from a high temperature liquid epoxy or a FBE, preferably a high temperature FBE, which provides excellent adhesion to the steel pipe and anti-corrosion protection, a maleic anhydride modified PVDF tie layer which provides excellent bonding to both FBE and PVDF topcoat, and substantially blocks water and oxygen degradation of the FBE by forming a protective, bonded, coating overtop of the FBE, and a PVDF layer which provides a further excellent water and oxygen barrier, as well as excellent mechanical protection. Also provided is a method of manufacturing a pipe having said coating system.
