scope:

Th is standard establishes minimum requirements for cold-applied petrolatum tape and petroleum wax tape coatings used on the exterior of steel water pipelines.

Th is standard describes exterior coatings that consist of cold-applied petrolatum or petroleum wax primer, petrolatum or petroleum wax saturated tape coatings, and their applications to special sections, connections, and fi ttings to be used with buried, submerged, and aboveground steel water pipelines. Th e primers and tapes are not intended for use with steel joints or sections of steel pipe where coatings of cement mortar or concrete are applied directly onto the bare steel pipe. Th ese coatings may be fi eld- or shop-applied according to the provisions of this standard.

Conditions not described in this standard. Th is standard does not describe the additional materials and procedures that may be required for difficult conditions, such as those encountered in building some submarine lines, casing pipe, river crossings, and lines that are in rocky areas or in severe soil stress. Consult the manufacturer for the additional materials and procedures that may be required for these conditions. Th ese materials may not be described in this standard.

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.

Purpose

The purpose of this standard is to provide purchasers, manufacturers, and constructors with the minimum performance requirements for cold-applied petrolatum tape and petroleum wax tape coatings, including material, application, inspection, testing, marking, and packaging requirements.

Application

This standard can be used as a guide for specifying, applying, inspecting, and testing cold-applied petrolatum tape and petroleum wax tape coatings conforming to ANSI/AWWA C217 for the exterior of special sections, connections, and fi ttings for steel water pipelines. Th e stipulations of this standard apply when this document has been referenced and then only to cold-applied petrolatum tape and petroleum wax tape coatings.
