Features of FBE Coating Pipe
1. FBE coating is corrosion resistant and chemical resistant
Properties of a fusion-bonded epoxy (FBE) external pipeline coating can be significantly affected by the conditions under which the FBE powder has been stored. Nova, An Alberta Corporation, and 3M Co. undertook a program of evaluating easily run tests to determine the suitability of FBE powder. These tests are less time consuming than the most commonly used series of tests which involve evaluating laboratory-coated specimens or testing rings taken from production-coated pipe. Detailed here is that study of powder aging, coating application, and laboratory testing of aged powders and the subsequent coatings obtained from these powders. The results indicate that gel-time test was the only powder-test method which was both speedy and accurate.
The coating composition of Fusion Bonded Epoxy Steel Pipe comprises: (a) from about 50 wt % to about 90 wt % of at least one epoxy resin; (b) from about 1 wt % to about 30 wt % of at least one catechol novolak-type adhesion promoter; and (c) from about 0.1 wt % to about 5 wt % of magnesium oxide.
