This standard practice provides the material characteristics, minimum system performance requirements, application methods, handling, shipping, and installation procedures for tape coatings for the prevention of external corrosion of underground or submerged pipelines. This standard is applicable to both carbon steel (CS) pipe and ductile iron (DI) pipe when the application of a tape coating system is desirable. This standard is intended for use by coating applicators, engineers, and pipeline owners as a guide to specifying application parameters.

The tape coatings covered in this standard are used as the external corrosion protection for new and existing pipes, girth welds, and fittings, and for repair and rehabilitation. The primary function of these tape coating systems is to pre- vent corrosion of the pipeline when used with or without cathodic protection (CP).
