Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy -based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars (though being phased out as of 2005 [1]) and on a wide ...
Galvanization. Galvanized surface with visible spangle. Galvanization or galvanizing ( also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten ...
When steel pipelines are built, they commonly consist of 10~12m long sections of steel pipe that has had a corrosion protective coating applied to it in a factory. The factory will leave an uncoated area at each end of the pipe called a "cutback" so that when welding the pipe sections together, the coating is not damaged.
Corrosion. Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.
Hot-dip galvanization. Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen ( O ...
Ductile iron pipe. Section of DICL pipe (ductile iron concrete lined), commonly used for utility water mains, showing iron casing, concrete lining, and textured polymer protective coatings on the inner and outer surfaces. Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. [1]
