Scope

1.1 This standard is intended to establish the minimum criteria necessary for use of a mechanically mixed, blended, epoxy barrier coating (AWWA Class I) that is applied to the interior of ½in. to 36 in. metallic pipe or tube used in pressurized piping systems for corrosion protection and to improve flow rates. There is no restriction as to the developed length of the piping system other than the method of application (“blow through”, spin cast or hand sprayed) and the characteristics of the epoxy coating being applied but the manufacturer’s engineer shall be consulted for any limitations associated with this product, process and its application for the end user.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This practice is for use by designers and specifiers, regulatory agencies, owners, contractors, and inspection organizations who are involved in rehabilitation of pressurized piping systems.
