Conidtion of Ductiie Iron Prior to Surface Preparatiou All ductile pipe and fittings shall be delivered to the application facility without asphalt. cement lining, or any other lining on the itterior surface. Because removal of old linings may Dot be possible, the intent of this specification is that the entire interior of due ductile iron pipe and fittings shall not have been lined with any substance prior to the application of the speci- fied lining mareriel and no coating shall have been applied to the fast six inches of the exterior of rho spigot ends. IL Lining Material The standard of quality is Ptotecto 401 Ceramic Epoxy. The material shall be an amine cured novalac epoxy containing at least 70% by volume of ceramic quarts pigment. Any request for substitution must be accompanied by a successful history of lining pipe and fittings for sewer service, a test report verifying the following properties, and a certirication of the test results. A. A, permeability rating of 0.00 when tested according ro Method A of ASTM E- 96 -66, procedure A with a test duration of 30 days. B. The following test must be rum on coupons from factory lined ductile iron pipe: 1 ASTM B -117 Salt Spray (scribed panel) - Results to equal 0.0 undercutting aficr two years. 2. ASTM G -95 Cathodic Disbondment 1.5 volts @ 77 °p. Results to equal no more than 0.5mm undercutting after 30 days. 3- Immersion Testing rated toting ASTM D- 714 -87. a. 20% Sulfltrie Acid —No effect after two years. b. 140 °F 25% Sodium Hydroxide --No effect after two years. c. 160°F Distilled Water —No effect after two years. d. 120 Tap Water (scribed panel) --0.0 undercutting after two years with no effect. C. An abasion resistance of no more than 3 mils (.075mm) loss after one million cycles using European Standard EN 598: 1994 section 7.8 Abrasion resistancc. M. APPLICATION A. Applicator The lining shall be applied by a competent firm with a successful history of applying lin- i ags to the interior of ductile iron pipe and fittings. B. Surface preparation Prior to abrasive blasting, the entire area to receive the protective compound shall be inspected for oil, grease, etc_ Any areas with oil, grease, or ally substance which can be removed by solvent, shall be solvent cleaned to remove those substances. Afar the surface has been matte free of grease, oil or other substances, all areas to receive the protective compounds shall be abrasive blasted using sand or grit abrasive media. The entire surface to be lined shall be struck with the blast media so that all rust, loose oxides, ate., arc removed from the surface. Only slight stains and tightly adhering oxide may be left on the =face. Any area where rust reappears before lining must be reblasted.

Lining "' After the surface preparation and within S hours of surface preparation, the interior of the pipe .shall receive 40 mils nominal dry filth thickness of Prctecto 401. N lining shall take place when the substrate or ambient temperature is is below 40 degrees Fahrenheit. The surface also roust be dry and dust free- If flange pipe or Finings are included in the project tine lining shall not be used on the face of the flange, D. Coating of Bell Sockets and Spigot Ends Due to the tolerances involved, the gasket area and spigot end up to 6 inches back from the end of the spigot end must be coated with 6 mils nominal, 10 mils maximum using PtotecrO Joint Compound. The Joint Compound shall be applied by brush to ensure cover• age. Care should be taken that the Joint Compound is smooth without excess buildup in the gasket seat or on the spigot ends. Coating of the gasket seat and spigot ends shall be done after the application of the lining. E. Number of Coats The number of coats Of lining matetiai applied shall be as recommended by the lining man- ufacturer. However, in ne case shall this ntatetiaI be applied above the dry thickness per coat rectmtmended by the lining manufacturer in printed literature. The maximum or mini - mum time between coats shall be that time recommended by the fitting material rnanuf4c- tuter. To ptrevent delatnination between which coats m , no material Shall be used for lining not R epai r tdy recoetatrie with Itself without roughening of the sttrface- F Touch -Up &Repair Ptotecto Joint Compound shall be used for touch -up or repair in accordance with manufactur- er's recommendations. TV- Inspetdlou and certlacation A. Inspection I. All ductile iron pipe and fitting linings shall be checked for thickness using a magnetic film thickness gauge. The thickness tasting shall be done using rite method outlined ill SSPC -PA -2 Film Thickness Rating. 2. The interior lining of all pipe and fittings shall be tested forpinholcs with 4 nondestruc- tive 2,500 volt test. Any defects found shall be repaired prior to shipment, 3. Bach pipejolnt and fitting shNl be marked with the date of application of the lining sys- tem along with its numerical sequence of application on that date and records main- tained by the applicator of his work. B. Certification The pipe or fitting manufacturer must supply a certificate attesting to the fact that the appli- cator met the requirements of this specification, and that the material used was as specified. Y Handling Ptoreeto 401 lined pipe and fittings must be handled only lYom the outside of the pipe and fit- tings. No forks, chains, straps. hooks, etc shall be placed inside the pipe and fittings for lift- ing, positioning, or laying. 0 is 0 c. 8 MAY -22 -2002 11:14 CENTEX CONSTRUCTION – DAL 972 233 2911 P.05i05 Procedures for sealing cut ends and repairing field damaged areas Of PROTECTO 401 lined pipe and fittings. EA �tlrsutEnde mp�ldcg � _of PROl'FCTA dof pwi 1. Remove burrs caused by field cutting of ends or handling damage and smooth out the edge of the lining if mugh. 2. Rcmove all traces of oil, grease, asphalt, dust, dirt, etc. Remove nay dariatgcd lining caused by field Cut- ting operations or handling and clean any exposed metal by sanding or scraping. Sandblasting or power too] cleaujny rougheaint is also acceptable. It is recommended that any loose lining be removed by chiseling, cutting, or scraping into well adhered lined area before patching. Be sure to overap at least I of lining in the area to be re;yaired. 4. with the arcs to b: scaled or repaired absolutely clean and suitably roughened, apply a cost of Pfotectc Joint Compound using the following procedure: a. Mixing Procedure—The repair kit fa Protecto 401 contains two small cm of Protecto Joint Compound_ Protecto Joint Compound is a two component epoxy and the contents of the small container shall be mixed with the contents of the large container. If Ins than the full contents of each can is to be mixed, the material may be mixed using the mixing ratio Printed on the IiiOcls. Afar Part B is added to Part A. the mi,tture shall be thoroughly agitated. All activated material must be used within one hour c mixing, b. Application of lilatcrial —After the nmterial has been thoroughly mixed, it can be applied to the prepared su dace by brush. Brushing is usually best due to the fact that the areas to be repaired are usually small. Practices con• ducivc to a good coating are contained in the technical data sheer for Protecto Joint Compound. S. It is important to coat the entire freshly cut exposed metal surface of the cut pipe end. To ensure proper sealing, overlap at least one inch of the lining with this repair material. DESCRIPTION: A brushable novalac epoxy designed for sealing au ends and repairs when pipes are Iined with Protecto 401 Ceramic Epoxy. LI4ITA7TONS: This material should be used on spigots and in bell sockets only after the pipe of fit. tiug is lined with Protecto 401 Ceramic Epoxy. Protecto Joint Compound can be used over Protecto 401 or on bare substrate. Note: Do not apply Protecto 401 over Protede Joint Compound. SURFACE PREPARATION: The surface prepara. lion shall be equal to She specifications for the pro. ject or as outlined in the touch -up Procedure. Do not apply Protecto Joint Compound over wet or frozen surfaces. DRY FIU M TIIICKNESS: As outlined in specifi- cations. APP nQN W6 APPLICATION: Brush, roll, or airless spray.
