AWWA C210 : 2024

This standard describes the material and application of shop-applied and field-applied liquid-epoxy coatings and linings used in the water-supply industry for steel water pipe, special sections, welded joints, connections, and fittings installed underground or underwater, under normal construction conditions.

1.1.1 Conditions not described in this standard. The coating systems described in this standard are not intended for use on pipe that will be bent after the coating or lining system has been applied.

1.1.2 Coating and lining systems. The coating and lining systems may consist of any of the following three types: (1) a two-part chemically cured epoxy primer and one or more coats of a different two-part chemically cured epoxy topcoat; (2) two or more coats of the same two-part chemically cured epoxy, in which case the first coat shall be considered as the prime coat; or (3) a single coat of a two-part chemically cured epoxy.

1.1.3 Maximum temperature. AWWA steel pipe coating and lining StandardDetails are based on the maximum service temperature of potable water. Consult the epoxy manufacturer for conditions and limitations.

1.1.4 Other substrates. When this standard is referenced for substrates other than carbon steel, the surface preparation methods, application methods and performance data listed in this standard may not be applicable and the coating manufacturer should be consulted.

This standard can be referenced in documents for liquid-epoxy coatings and linings for steel water pipe and fittings. The stipulations of this standard apply when this document has been referenced and then only to liquid-epoxy coatings and linings for steel water pipe and fittings.
