AWWA steel pipe coating and lining standards are based on the maximum service temperature of potable water. Consult the epoxy manufacturer for conditions.

When blasting equipment is employed using a recycled abrasive working mix, the abrasive working mix shall be main- tained free of contaminants oil, water, etc. The cleaned pipe surfaces shall be inspected for conformance to Sec.

Surface imperfections, such as slivers, scabs, burrs, weld spatter, and gouges, shall be removed by grinding. Ground areas shall meet the profile anchor pattern requirements of Sec. If abrasive material or other loose foreign mat- ter has entered the interior of the pipe, clean, dry, oil-free compressed air shall be used to remove the loose foreign matter in a manner that does not adversely affect the cleaned surface. Alternatively, vacuum cleaning or other methods may be used in place of compressed air.

Abrasive blast-cleaned pipe surfaces shall be protected from conditions of high humidity, rainfall, or surface moisture. Flash rust shall be removed before coating. When pipe sections are to be joined together by field welding, a band that is free of lining and coating shall be left on the inside and outside surfaces at the ends of the sections.

This band shall be of sufficient width as specified by the downloadr, to permit the making of field joints without damage to the lining and coating Sec. When specified by the pur- chaser and when rubber-gasketed joints or mechanical couplings are used, the epoxy coating shall extend to the ends of the pipe.

Otherwise a holdback of sufficient distance that will not interfere with gasket sealing surfaces shall be supplied. The epoxy thickness on the pipe surfaces that receive rubber sealing gaskets shall not exceed what is recommended by the manufacturer of the coupling. The temperature of the pipe during application shall conform to the recommendations of the epoxy manufacturer.

After final field assembly, the com- pound shall be completely removed. The exposed threads shall be coated as pro- vided in Sec. Epoxy repair shall be performed in accordance with Sec. The methods and practices found in AWWA C shall be followed for the handling, shipping, storage, and installation of pipe coated or lined with this material. Special requirements associated with the field procedures of pipe coated or lined with this material can be found in Sec.

No metal tools or heavy objects shall be per- mitted to come into contact with the finished coating or lining. Workers shall be permitted to walk on the coating or lining only when necessary, in which case only shoes with rubber soles and heels shall be permitted.

Coating or lining damaged during installation shall be repaired in accordance with Sec.

A heat-resistant material of sufficient width to prevent damage to the coating shall be placed on each side of the coating holdback during welding to avoid damage to the coating by hot weld spatter. No welding ground shall be made on the coated part of the article. Any coating or lin- ing damage from welding, including burns from weld spatter, shall be repaired in accordance with Sec.

Steel panels of dimensions 2 in. The uncoated side and edges shall be sealed with hot wax or other resis- tant material. Suitable containers shall be filled to a depth of 4 in. The panels shall be placed in the containers to allow exposure to both the liquid and vapor phases of the fluids. If multiple panels are placed in the same container, a distance of 1 in. Blistering, peeling, or disbondment of the epoxy shall constitute failure to pass the test.

The test shall run for 30 days. Each specimen shall be a laboratory-coated steel panel with minimum dimensions of 4 in. A single intentional holiday 0.

The disbondment shall be measured from the edge of the initial holiday along each radial cut. The average of these measure- ments shall be the result for each specimen. Three specimens shall be tested and the results averaged. An average value below the limit in Table 1 shall constitute a failure to meet the dielectric strength requirement.

The entire procedure of applying the epoxy materials as described in this standard may be inspected by the downloadr from surface prepara- tion to completion of application.

Such inspection shall not relieve the constructor of responsibility to provide materials and perform work in accordance with this standard.

PAGE Foreword 4. A Background B History C Acceptance A downloadr Options and 4. B Modification to Standard This standard was developed to provide for the use of liquid-epoxy coatings for the exterior coating and interior lining of steel water pipe.

The standard has been revised periodically to meet increasingly demanding environmental and health-effects regulations and to modify procedures based on technological advances. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including 1.

Specific policies of the state or local agency. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Use of Appendix A procedures may not always be identical, depending on the certifier. AWWA C does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1.

Determine additives requirements, including applicable standards. Determine the status of certifications by all parties offering to certify products for contact with, or treatment of, drinking water. Determine current information on product certification. Special Issues. This standard provides guidance to the water industry in selecting and evaluating liquid-epoxy coatings for use in potable water service and sets minimum requirements for linings and coatings used on steel water pipe in the potable water supply industry.

Users of this standard are advised to consider additional lining thickness for pipe that handles water containing higher than normal levels of particulates or that operates at higher than normal velocities. A penstock carrying mountain water would be a viable example. The required finished coating thickness shall be specified by the downloadr.

The specified thickness should not exceed the maximum recommended by the coating manufacturer. Soluble salts and other inorganic contaminants on a prepared steel surface have been known to influence coating performance.

Procedures for determining the presence of these contaminants as well as the method of quantifying them are currently being evaluated by technical organizations serving the paint industry. If an extended period of aboveground storage of the coated pipe is anticipated, consideration should be given to the ability of the coating to resist degradation by ultraviolet light and other atmospheric and environmental conditions.

The downloadr should consult the manufacturer for specific conditions and limitations. This standard does not cover materials and procedures that may be required for difficult conditions, such as those encountered in construction of some submarine lines, casing pipe, river crossings, and in rocky areas.
