(FBP) is widely used in fire protection systems almost everywhere. Practically, they are produced by External coating for galvanized or black steel pipes are performed with the aid of fusion-bonded polyester powder with minimum thickness of 150 microns.
Abrasive cleaning with steel grit/shot is required to achieve a surface purity grade of Sa 2 1/2 with anchor pattern of (40-90 μm). The steel must reach a temperature of 170-220Co.The FBP is deposited by an electro-static spray process. The coating cures quickly. Once cured, the pipe is cooled for safe handling and inspection. Thus it can be said that the coated pipe is ready for installation and use.
