Provides purchasers and manufacturers of steel pipes with a specification for external fusion-bonded epoxy coating of steel pipes for protection against corrosion.

This Standard specifies requirements for external fusion-bonded epoxy (FBE) coating of steel pipes for protection against corrosion. It includes coating in the mill and coating in the field.NOTES: 1 Guidelines to purchasers on information that should be supplied by the purchaser and those variables that should or may be agreed upon at the time of inquiry or order are given in Appendix A.2 Line pipe manufactured in accordance with API 5L may not be suitable for application of FBE coating without requiring additional surface preparation. Surface imperfections in the form of steel slivers, burrs and laminations can cause excessive holidays, resulting in the need for extra surface cleaning, grinding or filing.3 Line pipe manufactured in accordance with API 5L may require a more stringent straightness specification to allow coating in accordance with this Standard.4 Consideration should be given to strain ageing when specifying line-pipe for FBE coating. Guidance is given in Clause 3.1.2, Note 3.Methods for demonstrating compliance with this Standard are given in Appendix B.
