This and other standards are referenced throughout this Section either by the full ANSI/AVVVVA designation or by only the AVCNA nurnbenng, such as AVV~VA C104. Along with technical and metallurgi- cal advancement in piping materials, research on lining requirements for pipe and fittings has resulted in the develop- ment of linings to meet many different service requirements. AMERICAN offers several types of linings, the most common being Portland* cement mortar lining. Pipe and fittings furnished by AMER- ICAN are offered unlined or with linings as follows: 1. Cement Lined per AWWA C104. 2. Asphaltic Lined per AVVVVA Cl10, Cl15 or C151. 3. Fusion Bonded Epoxy for 4"-16" Fastite fil:tings per AVWNA C116. **4. Polybond Lined - AMERICAN's polyethyJene lining. **5. PotybondPlusTM lined - AMERI- CAN'S Polyethylene - fusion bonded com- posite lining system. **6. Coat Tar Epoxy Lined - resin and tar combination. 7. Special Lining - for unusual service conditions. Cement Lining Cement-mortar lining for ductile iron pipe and ductile and gray iron fittings for water service is in accordance with ANSI/AWVVA C104/A21.4. Cement-lined pipe is also furnished for some sewage service and a number of other applications. In fact, most pipe fumished is cement lined, providing improved flow char- acteristics and the required protection against internal corrosion. The cement lining is satisfactory for temperatures up to 212°F. If asphaltic seal coat is furnished, the lining is only adequate for temperatures up to 150°F. For other services contact AMERICAN regarding temperature limitalJons of cement lining. The first recorded installation of cement-lined gray iron pipe was in 1922 at Charleston, S.C. This lining was developed by the Charleston Commission of Public Works in cooperation with American Cast Iron Pipe Company. Since this beginning, AMERICAN has furnished most of its pipe with cement lining. The lining is applied cen- tdfugally with the speed of rotation designed to produce a smooth waterway surface, free from voids and yet retaining enough tools- ture for proper cudng. AMERICAN cement lined pipe &nd fittings are listed by ANSI/NSF Standard 6't for potable water contact. Flow tests on cement-lined pipe under varying service conditions have established that the Hazen-Williams flow coefficient remains as expected at about 140. Handling Cement-Lined Pipe and Fittings Pipe and fittings with cement lining shouId be handled with rubber covered hooks or other type equipment to prevent damage to the cement lining. Bare fork lift arms or bare hooks should not be inserted into open ends. Characteristics of Cement Lining AWWA C104 allows for surface crazing and cracks of a specified nature and magni- rude. Occ~sionaUy cracks and looseness in linings may occur pdor to installa'don, par'dc- ulady where pipe is stored for a considerable time. Many years' experience with cement- lined pipe and fittings has vedfied that this condition is in no way detrimental to the performance and effectiveness of the lining. When a cement-lined pipe is placed in service and filled with water, t~vo reactions 11-1 begin immediately. The first is a gradual elimination of the temperature differential between pipe and lining, thus eliminating any stresses in the lining due to this condi- tion. Secondly, the lining begins to absorb water. Water is absorbed into the pores of the cement and into the capillary channels of the calcium silicate gel The water absorption causes the lining to sweil, restormg it to inti- mate contact with the pipe wall and virtually closing any cracks present in the lining. This swelling process is relatively slow, taking up to severaJ weeks for the lining to be restored to its maximum volume. This process has been demonstrated on a number of occa- sions to the satisfaction of customers, con- tractors and engineers by immersing a pipe or fitting in water for one or bA, o weeks. After a period of exposure to water, not only does the lining tighten against the pipe wall and the cracks close, but finally the sur- faces of the cracks actually re-bond. This occurs by a process called autogenous heal- ing. This phenomenon, long recognized by the cement industry, has been documented by laboratory tests to occur in cement-Iined ductile pipe. In one test, a 48" ductile iron pipe with severely cracked cement lining was held half full of water for several months. At the end of that pedod, the lining both above and below the water surface was found to be tight, with all cracks either healed com- pletely or sealed by the formation of ca~dum c~rbonate. Field inspections of lines that have been in service for many years have vedfied the laborato~, results; cement linings do tighten a. nd heal in service, and provide the corro- sion protection to the pipe and the high flow coefficients for which they were designed. Field Repair of Damaged Ceme~ Linings Cement lining will withstand normal handling; nevertheless, pipe or fittings may be found at times to have damaged linings which need to be repaired before placing in service. AWWA C104 provides that damaged lining may be repaired, and the following repair procedure is recommended: 1. Cut out the damaged lining to the metal. Square the edges. 2. Thoroughly wet the cut-out area and adjoining lining. 3. With the damaged area deaned and the adioining lining wet. spread the mortar (see recommended mix below) evenly over the area to be patched. (See Table No. 11-1 for lining thicknesses.) After the tining has become firm and adheres weft to the surface, finish it with a wet 3" or 4" p~dnt brush or similar soft bnstie brush. 4. The repaired lining should be kept moist by tying canvas or wet budap over the ends of the pipe or fitting for at least 24 hours. As an alternative the repaired lining may be seal coated with a cut back type of asphaltic seal coating. This must be sprayed or brushed on within 5 to 30 minutes after lining. To maintain NSF certification, patch must be made using a NSF certified cement for 4" pipe and lazger or the patch must be topcoated with NSF cerdfled asphaJt paint. Recommended Cement Mix Cement mix by volume: 3 Parts Portland Cement; 2 Parts Clean Sand; neces- sary water for slump of 5" to 8". The sand should be flee of clay and screened through a No. 20 Screen· Precautions 1. Mortar for lining should not be used after it has been mixed for more than one hour. 2. Too rapid a loss of moisture from fresh linings due to hot weather or high wind will prevent proper cure, resulting in the lin- ing being soft and powdery. To prevent this loss of moisture, (a) do not line hot ca_~dn~ and (b) dose the ends of the castings with wet budap. 3. Fresh linings which become frozen will not be serviceable. Avoid lining in freez- lng weather. 11-2 Standard Specification For Lining Ductile Iron Pipe For Sewer Service Condition of Ductile Iron Prior to Surface Preparation All ductile pipe and fittings shall be delivered to the application facility without asphalt, cement lining, or any other lining on the interior surface. Because removal of old linings may not be possible, the intent of this specification is that the entire interior of the ductile iron pipe and fi~ngs shall not have been lined with any substance prior to the application of the speci- fied lining material and no coating shall have been applied to the first six inches of the exterior of the spigot ends. Lining Material The standard of quality is Protecto 401 Ceramic Epoxy. The material shall be an amine cured novalac epoxy containing at least 20% by volume of ceramic quartz 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 certification of the test results. A. A permeability rating of 0.00 when tested according to Method A of ASTM E-96-66, Procedure A with a test duration of 30 days. B. The following test must be run on coupons from factory lined ductile iron pipe: 1. ASTM B-117 Salt Spray (scribed panel) - Results to equal 0.0 undercutting after two years. 2. ASTM G-95 Cathodic Disbondment 1.5 volts @ 77°F. Results to equal no more than 0.5mm undemutting after 30 days. 3. Immersion Testing rated using ASTM D-714-87. a. 20% Sulfuric 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°F 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 resistance. III. APPLICATION A. Applicator The lining shall be applied by a competent firm with a successful history of applying Iin- ings 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 any substance which can be removed by solvent, shall be solvent cleaned to remove those substances. After the surface has been made free of grease, oil or other substances, ail 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, etc., removed from the surface. Only slight stains and tightly adhering oxide may be left on the surface. Any area where rust reappears before lining must be reblastud. Procedures for sealing cut ends and repairing field damaged areas of PROTECTO 401 lined pipe and fittings. procedures for sealin~ cut ends and renairinn field damaged areas of PROTECTO 401 lined nine and fittings. 1. Remove burrs caused by field cutting of ends or handling damage and smooth out the edge of the I~nthg if rough. 2. Remove all traces of oil, grease, asphalt, dust, din, etc. 3. Remove any damaged lining caused by field cut- ting operations or handling and clean any exposed metal by sanding or scraping. Sandblasting or power tool c]eanthg roughening is also acceptable. It is recommended that any loose lining be removed by chiseling, cutting, or scraping into well adhered lined area before pamhing. Be sure to overlap at least 1" of lining in the area to be repatred. 4. With the area to be sealed or repmred absolutely clean and suitably roughened, apply a coat of Protecto Joint Compound using the following procedure: a. Miking Procedure--The repair kit for Protecto 401 contains two small cans of Prmecto 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 less than the full contents of each can is to be mixed, the material may be mixed using the mixing ratio printed on the labels. Afier Part B is added to Part A, the mixture shall be thoroughly ag/rated. All activated material must be used within one hour of mixing. b. Application of Material--After the material has been thoroughly mixed, it can be applied m the prepared surface by brush. Brushing is usually best due to the fact that the areas to be repaired are usually small. Practices con- ducive to a good coating are contained in the technical data sheet for Protecto Joint Compound. 5. It is important to coat the entire freshly cut exposed metal surface of the cut p~pe end. To ensure proper sealing, overlap at least one inch of the lining with this repair material.
