The objective of this Standard is to provide purchasers and manufacturers of petroleum pipelines with a Standard for the specification of pipeline coatings using external fusion-bonded epoxy.

Scope

This Standard specifies requirements and methods of test for external fusion-bonded epoxy (FBE) coating of steel pipes for protection against corrosion. This Standard covers both single-layer and multi-layer coating systems.
NOTE 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.
NOTE 2 Line pipe manufactured in accordance with API 5LW 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.
NOTE 3 Line pipe manufactured in accordance with API 5LW may require a more stringent straightness specification to allow coating in accordance with this Standard.
NOTE 4 Consideration should be given to strain ageing when specifying line-pipe for FBE coating. Guidance is given in Clause 3.1.3.
Methods for demonstrating conformance with this Standard are given in Appendix B.
