3.2 PREPARATIONA. Correct defects or conditions which may interfere with or prevent a satisfactory installation.B. Assure ends of pipe to be fitted with flanges have all protrusions ground flush.3.3 ERECTION/INSTALLATION/APPLICATIONA. Joining Method - Flanged Joints1. Install in accordance with AWWA C115.2. Extend pipe completely through screwed-on flanged and machine flange face and pipein single operation.3. Make flange faces flat and perpendicular to pipe centerline.4. When bolting flange joints, exercise extreme care to insure that there is no restraint onopposite end of pipe or fitting which would prevent uniform gasket compression orwould cause unnecessary stress, bending or torsional strains to be applied to castflanges or flanged fittings.5. Allow one flange free movement in any direction while bolts are being tightened.6. Do not assemble adjoining flexible joints until flanged joints in piping system havebeen tightened.7. Gradually tighten flange bolts uniformly to permit even gasket compression.B. Joining Methods - Push-on Mechanical (Gland-Type) Joints1. Install in accordance with AWWA C111.2. Assemble mechanical joints carefully according to manufacturer's recommendations.3. If effective sealing is not obtained, disassemble, thoroughly clean, and reassemble thejoint.4. Do not overstress bolts.5. Where piping utilizes mechanical joints with tie rods, align joint holes to permitinstallation of harness bolts.C. Joining Method - Push-On Joints1. Install in accordance with AWWA C111.2. Assemble push-on joints in accordance with manufacturer's directions.3. Bevel and lubricate spigot end of pipe to facilitate assembly without damage to gasket.Use lubricant that is non-toxic, does not support the growth of bacteria, has nodeteriorating effects on the gasket material, and imparts no taste or odor to water inpipe.4. Assure the gasket groove is thoroughly clean.5. For cold weather installation, warm gasket prior to placement in bell.6. Taper of bevel shall be approximately 30 degrees with centerline of pipe andapproximately 1/4 IN back.D. Flange Adapters 12 IN and less1. Locate and drill holes for anchor studs after pipe is in place and bolted tight.2. Drill holes not more than 1/8 IN larger than diameter of stud projection.15062 - 411/07 PIPE: DUCTILE IRON
