Brief Introduction

This standard specifies requirements for factory-applied three-layer extruded polyethylene-based coatings,and one- or multi-layered sintered polyethylene-based coatings for the corrosion protection of steel pipes and fittings.

This standard sets minimum requirements for shop‑ and field‑applied, liquid‑epoxy interior linings and exterior coatings used in the water‑supply industry for steel water pipelines 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 coating, in which case the first coat shall be considered as the prime coat; 

(3) a single coat of a two‑part, chemically cured epoxy coating. Maximum temperature. AWWA steel pipe coating standards are based on the maximum service temperature of water. The purchaser shall consult the coating manufacturer for conditions and limitations.
