Standard Practice for the Application of Spray-Applied Polymeric Liners Inside Pipelines for Potable Water
 N F3182

Annotation

This practice describes the procedures for the rehabilitation of potable water pipes using spray-applied polymeric coatings for pipelines constructed of iron, steel, or asbestos cement using resin materials that have been certified in accordance with NSF/ANSI Standard 61 for the in-situ lining of potable water mains.

This practice applies to potable water pipelines constructed of metallic or asbestos cement piping in the diameter ranges of 4 in. (10 cm) to 36 in. (90 cm). Specialist advice should be sought from the product manufacturer for polymeric linings applied to other nonmetallic surfaces and for applied linings outside of these diametric limitations.

This practice applies to in-situ pipes requiring AWWA Class I (nonstructural) linings through Class III (semistructural) linings (see AWWA M28).

This practice does not address lining system design. Assistance with lining system design is available from lining system manufacturers and operators who have been professionally trained and experienced in polymeric liner design.

Units—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.

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.
