r2.2.4 . Brine Main Polvvinxl Chloride Pipe (Cont'd) PVC pipe shall be homogeneous throughout and free from visible cracks, holes, foreign inclusions, or other injurious defects. The pipe shall be as uniform as commercially practical in color, opacity, density and other physical properties . The pipe shall be white in color. All Brine Main pipe shall be compression ring, push on type joints conforming with applicable AWWA Specifications . No solvent, weld or threaded joints will be permitted. Pipe Fittings All underground fittings shall be restrained point conforming to ANSI Specifications A21 . 11 for 250 psi pressure (gray iron or ductile iron) unless otherwise specified or noted. In making the joint, the surface with which the rubber gasket comes in contact shall be brushed thoroughly with a wire brush just prior to assembly to remove all loose rust or foreign material, and to provide clean surfaces, which should be brushed with soapy water, just prior to slipping the gasket over the spigot end and into the bell. Brush soapy water over the gasket, prior to ' installation, to remove loose dirt, and lubricate the gasket as it is forced into its retaining space . The sequence of assembly is to be as follows : The gland, followed by the rubber gasket, is to be placed over the spigot end, which is inserted into the socket. The gasket should be pushed in position so that it is evenly seated in the socket. The gland is then moved into position against the face of the gasket. Bolts are then to be inserted and made finger tight. ' When tightening bolts, it is essential that the gland be brought toward the pipe flange evenly, maintaining approximately the same distance between the gland and the face of the flange at all points around the socket. This may be done by partially tightening the bottom bolt first, then the top bolt, next the bolt at either side, and last, the remaining bolts. This cycle is to be repeated until all bolts are within the following range of bolt torque: it e rif KTq ' ueELMYze . .. _ . eddec `._ + f Wrench 3 .4" 60' — 90 lbs. 3/4 " 10 " The above torque load may be applied with the torque measuring or indicating wrench, length of wrench recommended above. If effective sealing is not attained at the maximum torque indicated above, the joint should be disassembled and reassembled after thorough cleaning. Overstressing of bolts to compensate for poor installation shall be avoided. All underground fittings shall be restrained joint conforming to ANSI Specifications A21 . 11 . All fittings on PVC pipe shall be restrained with 1300 series retainer glands . 9
