1.4.5 Manufacturer’s Recommended Practices. Storage, surface preparation, and application for coating materials shall be in accordance with the manufacturer’s recommendations.

2.0 UNDERGROUND PROTECTIVE COATINGS. The Contractor shall furnish and apply a protective coating to the exterior surface of all underground, buried steel piping.

The exterior surface of buried steel piping shall be cleaned, coated, tested, and handled in accordance with AWWA C203 together with the applicable sections in the appendices of those specifications, or JEA approved equal. The applicable sections of those specifications have been incorporated herein. The interior of the pipe shall be cleaned, grit or sand blasted, and coated in the shop.

2.1 Coatings. The protective coating for the exterior surfaces of steel pipe shall consist of a coat of coal-tar primer, a 3/32 inch thick coating of hot coal-tar enamel, a fibrous glass mat, a 4 mil thick coating of hot coal-tar enamel, a bonded wrap of nonasbestos felt, and a coating of white wash. The exterior surface of pipe to be totally encased in concrete shall be coated with the coal-tar primer only.

2.2 Application. The protective coating shall be applied as specified below.

-5

2.2.1 General. The protective coatings shall be shop applied after fabrication and before erection except for the surfaces at the pipe ends. The coating shall be left off of pipe ends for a distance of approximately 6 inches to permit the welding of joints without injury to the coatings.

After the sections of pipe are welded together, the areas left uncoated and all damaged areas shall be cleaned and coated.

2.2.2 Workmanship. All work shall be done in a thorough workmanlike manner. The entire operation of priming the pipe and heating and applying the coal-tar epoxy and enamel coatings shall be performed under the supervision of and by experienced personnel skilled in the application of coal-tar enamel and coal-tar epoxy coating systems.

2.2.3 Equipment. The Contractor's equipment for all blasting, priming, enameling, and painting shall be designed and manufactured for the specific application and shall be in such condition as to permit applicators to follow the procedure and obtain results prescribed in these specifications.

2.2.4 Preparation of Surfaces. All surfaces of piping shall be thoroughly cleaned in accordance with Steel Structures Painting Council (SSPC) Surface Preparation Specification No.1, Solvent Cleaning to remove all oil, grease, moisture, dirt, rust, mill scale, weld scale, and other foreign materials prior to the application of any coating. This shall be accomplished by the use of suitable solvents to remove oil and grease, followed by sandblasting. The solvent shall be Xylol or some other suitable coal-tar base solvent. Dirty solvent shall not be used. Dirty and/or oily rags shall also not be used. The Contractor shall place all used solvent and rags in a suitable container and remove them from the site for disposal in an environmentally safe manner.

Exterior surfaces shall be dry grit blasted in accordance with Steel Structures Painting Council (SSPC) Surface Preparation Specification No. 10, Near-White Blast Cleaning. Interior surfaces shall be dry grit blasted in accordance with SSPC-SP5, White Metal Blast-Cleaning. Grit and dust shall be removed thoroughly by blowing before primer is applied.

All other foreign matter not removable by blasting shall be removed by suitable means. Blasted surfaces that rust before a priming coat has been applied shall be cleaned of all rust by buffing or wire brushing or, at the discretion of JEA, shall be reblasted. Adequate air separators shall be used to remove all oil and free moisture from the air supply to the blaster.

After cleaning, the pipe shall be protected from and maintained free of all oil, grease, moisture, and dirt that might fall upon the pipe from whatever source until it has received its final enamel coat. Any pipe showing pits after beginning of blasting shall be set aside immediately, pending examination by JEA, for approval, reconditioning, or rejection.

Blast cleaned surfaces shall be checked for the specified profile depth and degree of cleanliness prior to application of coating materials. Profile depth shall be checked. Degree of cleanliness shall be checked using Swedish Pictorial Standard in accordance with SSPC-Vis-1-92 T.

2.2.5 Priming. All blasted steel surfaces shall be cleaned of dust and grit and shall be primed immediately following blasting and cleaning. The surfaces shall be dry at the time the primer is applied, and no primer shall be applied during rain, fog, or dusty conditions unless protected from the weather by suitable housing.

-6

At the option of the Contractor, the application of the primer shall be by hand brushing, air gun spraying, or spraying and brushing, and shall be in accordance with instructions for application as supplied by the manufacturer of the primer. The apparatus to be used for application of the primer shall be approved by JEA. Spray gun apparatus to be used shall include a mechanically agitated pressure pot and an air separator that will remove all oil and free moisture from the air supply.

The use of coal-tar primer that becomes fouled with foreign substances or has thickened through evaporation of the solvent oils will not be permitted.

After application, the priming coat shall be uniform and free from floods, runs, sags, drips, holidays, or bare spots. Any bare spots or holidays shall be recoated with an additional application of primer. All runs, sags, floods, or drips shall be removed by scraping and cleaning and the cleaned area retouched, or, at the discretion of JEA, all such defects shall be remedied by reblasting and repriming. Suitable measures shall be taken to protect the wet primer from contact with rain, fog, mist, spray, oil, grease, dust, insects, or other foreign matter until completely hardened and the epoxy or enamel coating has been applied.

Any time when moisture collects on the steel, the steel shall be warmed to a temperature of approximately 86° F-100° F for sufficient time to dry the pipe prior to priming. To facilitate spraying and spreading, the primer may be heated and maintained during the application at a temperature of not more than 120° F. In no case shall the coatings be applied when the surface temperature is less than 38° F above the dew point.

The minimum and maximum allowable drying time of the primer between application of primer and application of coal-tar epoxy or enamel shall be in accordance with instructions issued by the manufacturer of the primer unless otherwise directed by JEA. If the epoxy or enamel coat is not applied within the maximum time after priming, as required by the manufacturer or as directed by JEA, the pipe shall be reprimed with an additional light coat of primer, or, at the discretion of JEA, the entire prime coat shall be removed by reblasting and the pipe reprimed.

2.2.6 Preheating of Primed Pipe. When moisture tends to collect on cold pipe, enameling shall be preceded by warming the pipe.

Warming shall be done by any method which will heat the pipe uniformly to the recommended temperature without injury to the primer. Steel temperature of the pipe shall not exceed 160° F.

After heating and while the pipe is at its highest temperature, the inside lining epoxy shall be applied, and then the exterior coatings applied.

2.2.7 Preparation of Coal-Tar Enamel Coating. The enamel shall be heated in approved heating kettles equipped with accurate and easily read thermometers. In addition, JEA reserves the right to provide recording thermometers; such thermometers shall be installed on the heating kettles as directed by JEA and at the expense of the Contractor. Such thermometers will be checked and adjusted by JEA whenever necessary. The charts therefrom shall constitute a basis for acceptance or rejection of any enamel because of improper heating or handling, or both.

The operating or supply kettles, or both, shall be provided in sufficient numbers so that the enamel may be heated and coordinated with the application procedure. No enamel shall be held in the operation kettles at application temperatures for a longer period then recommended by the manufacturer or stated in his instructions. The enamel heated in supply kettles shall not exceed the temperatures and melting periods recommended by the coating manufacturer. Operating kettles shall not be used as a continuous source of supply by adding unmelted enamel during the time they are in use but shall be completely emptied of one charge and cleaned, if necessary, before the next charge of unmelted enamel is added; except when mechanically agitated kettles are used or if the kettle capacity does not exceed 53 gallons. Kettles shall be covered with hinged lids which may be securely fastened down and shall be tightly closed during the heating and application of enamel except for necessary loading and stirring.

The enamel shall be maintained moisture and dirt free at all times prior to, and at the time of, heating and application.

In loading the kettles, the enamel shall be broken into pieces suitable for the heating equipment used.

-7

In heating the enamel, the charge shall be melted and brought up to application temperature as rapidly as possible without injury to the enamel. The temperature at which the enamel will be applied shall be in accordance with the recommendation furnished by the manufacturer.

The hot enamel shall be thoroughly stirred at intervals not exceeding 15 minutes regardless of whether the enamel is being used from kettles or is being held ready for use. Iron paddles shall be used for stirring. Wooden paddles will not be permitted.

Enamel that has been heated in excess of the maximum allowable temperature, or that has been held at application temperature for a period in excess of that specified, shall be condemned and rejected. Fluxing the enamel will not be permitted.

Excess enamel remaining in a kettle at the end of any heat shall not be included in a fresh batch in an amount greater than 10 percent of the batch. Kettles shall be emptied and cleaned frequently as required. The material removed in cleaning the kettles shall be dumped and wasted.

2.2.8 Coal-Tar Enamel Application to Exterior Steel Surfaces. The primed exterior steel surface to be enameled shall be dry and clean at the time the enamel is applied. Any damage occurring to the primer coat shall be repaired by retouching before application of the enamel. The brush strokes of enamel shall be made in the direction of flow. All brush strokes shall overlap and form a continuous coating. The daubing may be done by the double-lap or "shingling" method. The work shall be done in a workmanlike manner, and no indiscriminate smearing of the enamel will be permitted. On all welds the strokes of the first coat of enamel shall be applied along the weld.

The fibrous glass mat shall be applied simultaneously with the first coat of coal-tar enamel. Sufficient tension shall be applied to the roll of fibrous glass mat to embed it in the enamel before the enamel sets or cools. The fibrous glass mat shall not be pulled through the hot enamel to the metal surface. The thickness of the coal-tar enamel under the mat shall be 3/32 inch, and the allowable variation in thickness shall not exceed 4 mils. The mat shall be spiral wrapped smoothly with an overlap of 1/2 inch.

The second coat of hot coal-tar enamel (4 mils minimum thickness) shall be applied over the fibrous glass mat simultaneously with the bonded wrap of nonasbestos coal-tar saturated felt. The coating of whitewash shall then be applied over the nonasbestos felt.

Enameling buckets shall be filled from the heating kettles with ladles or from spigots attached to the kettles and shall not be dipped for filling. Buckets shall be kept clean and free of dirt at all times and shall not be set directly upon the ground or on enameled surfaces but shall be set upon suitable pads or blocks. Buckets shall not be allowed to accumulate excess chilled enamel but shall be kept clean.

Enamel shall not be used from enameling buckets below the minimum temperature specified by the manufacturer.

All drips and splashes of enamel on primed surfaces shall be carefully scraped off before the hand brushed coat of enamel is applied. This pertains particularly where overhead hand enameling is necessary inside of pipe or specials.

Hand enameling daubers shall be of the size best adapted for the work. Daubers shall be made of the best grade of Tampico Fiber set in solid hardwood handles. Mops, sweeps, or knot daubers shall not be used. Long hand horseshoe daubers will be acceptable for large areas and flat work.

The enameled pipe shall not be rolled or supported on its enameled surface until thoroughly cooled and hardened.

After field pressure tests have been completed, the exterior field weld areas and any exterior damaged areas shall be cleaned and primed. When the primer is dry, the surfaces shall be coated to the specified thickness. Enamel shall overlap the coating on each side of the field joint to form a continuous external coating free from defects.

2.3 Testing. Both before and after erection, 100 percent of all coated areas shall be inspected by the Contractor using an electric holiday detector. Holiday detector voltage shall be between 12,000 and 14,000 volts, unless recommended at another voltage setting by the holiday detector manufacturer. Any flaws or holidays found in the coated areas shall be repaired by the Contractor.

-8

2.4 Handling of Coated Pipe. Coated pipe shall be handled with equipment such as stout, wide belt slings and wide padded skids designed to prevent damage to the coating. Bare cables, chains, hooks, metal bars, or narrow skids shall not be permitted to come in contact with the coating.

The Contractor shall use every precaution to prevent damage to protective coating on the pipe. No metal tools or heavy objects shall be unnecessarily permitted to come in contact with the finished coating. Workers will be permitted to walk upon the coating only when necessary, and in case of such necessity the workers shall wear shoes with rubber or composition soles and heels. This shall apply to all surfaces, whether bare, primed, epoxied, or enameled.

Pipe shall be stored along the trench side, supported on wooden timbers placed under the uncoated ends to hold the pipe off the ground.

Pipe shall be hoisted from the trench side to the trench by means of a wide belt sling. Chains, cables, tongs, or other equipment likely to cause damage to the enamel coating will not be permitted, nor will dragging or skidding the pipe.

The Contractor shall allow inspection of the coating on the underside of the pipe while suspended from the sling. Any damage shall be repaired before lowering the pipe into the trench.

3.0 SPECIAL CONCRETE COATINGS AND SEALERS.
