This standard describes the material and application requirements for
fusion‑bonded epoxy coatings for the interior and exterior of steel water pipe, special
sections, welded joints, connections, and fittings for steel water pipelines installed
underground or underwater. Fusion‑bonded epoxy coatings are heat‑activated,
chemically cured coating systems.
1.1.1 Minimum pipe diameter. The minimum pipe diameter for application
of an internal coating that can be inspected and repaired by entering the pipe
shall be 24 in. (600 mm).* Pipe diameters less than 24 in. (600 mm) that can be
electrically inspected internally may be included, provided the work complies with
applicable provisions of this standard.
1.1.2 Maximum temperatures. AWWA pipe coating standards are written
for and based on the service temperature of potable water. Consult the coating
manufacturer for conditions and limitations.
