(Practice)Standard Practice for Internal Non Structural Epoxy Barrier Coating Material Used In Rehabilitation of Metallic Pressurized Piping Systems
Standard Practice for Internal Non Structural Epoxy Barrier Coating Material Used In Rehabilitation of Metallic Pressurized Piping Systems
SIGNIFICANCE AND USE
5.1 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.
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 1/2 in. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions—Definitions are in accordance with Terminology and abbreviations are in accordance with Terminology D1600,
unless otherwise specified.
3.2 Definitions:
3.2.1 accredited certifying organization, n—an agency accredited by an independent and authoritative conformity assessment
body (ANSI, ISO/ICC or equivelant) to operate a material and product listing and labeling (certification) system that is accepted
by the Authority Having Jurisdiction.
3.2.2 AWWA class I linings, n—Non-structural systems, such as traditional CML and epoxy. (See AWWA Rehabilitation of
Water Mains.)
3.2.3 listed (third- party certified), adj—equipment or materials included in a list published by a listing agency (accredited
conformity assessment body) that maintains periodic inspection on current production of listed equipment or materials and whose
listing states either that the equipment or material complies with approved standards or has been tested and found suitable for use
in a specified manner.
3.2.4 metallic piping, n—a tubular shape made of metal, intended to convey fluids or gas. Usually semi-rigid or rigid metal such
as galvanized steel, galvanized wrought iron black steel, stainless steel, copper, brass or similar metal piping systems.
4. Material Requirements
4.1 When applied to potable water systems, epoxy barrier coatings shall be evaluated, tested and certified for conformance to
NSF/ANSI 61, Section 5 for the intended application, field or factory or the health effects portion of NSF/ANSI 14 by an accredited
certifying organization.
4.2 Epoxy barrier coatings shall be prepared for application using mechanically engineered metering and mixing methods to
ensure mixing and dispensing controls to manufacturer’s specifications.
4.3 Epoxy barrier coatings shall be listed and identified for the type of application (“blow through”, spin cast or hand sprayed).
5. Significance and Use
5.1 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.
6. Coating Application
6.1 General—The epoxy coating shall be applied in accordance with the manufacturer’s recommendations. Application shall be
by blow through, airless-spray or centrifugal-wheel equipment or manufacturer-certified equal. “Blow through” application shall
be limited to 6-in. diameter pipe and shall be applied from small diameter to large. Spin cast applications shall be pre-planned in
accordance with the manufacturer’s recommendations, which are dependent on pipeline diameter, length and architecture and shall
be applied at change of diameter both ways. Random spool pieces of pipe shall be installed within the network architecture for
subsequent third party inspection when required or specified by owners or their designated representatives.
6.2 Piping preparation—Prior to abrasive blast cleaning, surfaces shall be inspected and, if required, cleaned according to
SSPC-SP 1 to remove oil, grease, or other foreign matter. Only solvents approved by the epoxy coating manufacturer shall be used.
Preheating of metallic type piping to remove oil, grease, mill scale, water, and ice may be used provided the pipe is preheated in
a uniform manner to avoid distorting the pipe. All leaks in the piping system shall be repaired in accordance with the
manufacturer’s recommendations prior to coating.
6.3 Abrasive blast cleaning—The interior of the piping system surfaces shall be abrasive blast cleaned to achieve a clean metal
surface conforming to SSPC-SP 6/NACE. No. 3 Abrasive blast cleaning and coating shall only be performed when the metal
temperature is more than 5 °F (2.9°C) above dew point. When required to meet the standard, or as required by manufacturer’s
instructions, the cleaning process shall be conducted both ways, from small diameter to large and from large diameter to small,
to ensure all foreign material on the wall of the pipe is removed.
6.4 Pipe Cleaning—A description of the quality and cleanliness of the pipe to be coated shall be required. When viewed without
magnification, the cleaned surface shall be free of all visible oil, grease, dirt, mill scale, rust and previously applied coatings.
Evenly dispersed, very light shadows, streaks, and discolorations caused by stains of mill scale, rust and old coatings shall be
permitted to remain on no more than 33 percent of the surface to be coated. The manufacturer’s instructions shall require that the
details of the visual observation of the cleaned pipe to be recorded.
6.5 Interior cleaning—If abrasives or other loose foreign matter has entered the interior of the piping system, then clean, dry,
oil-free compressed air shall be used to remove the loose foreign matter in a manner that does not adv
