Smearing the outsidewith chalk dust helps the location of cracks.1.10.1 If doubt persists further confirmation may be obtained by purring a littlekerosene of the inside of the pipe at the suspected spot. If a crack is presentthe kerosene seeps through and shows on the outer surface any pipe foundunsuitable after inspection before laying shall be rejected.1.11 Laying and jointing of CI pipes and fittingsThe laying of CI pipe lines shall, in general be in accordance with ofspecifications given in IS: 3114 shall also be followed as applicable.Urban Administration & Development Department Page 22
1.12 Lead Joints1.12.1 Pig Lead-Pig lead should be of uniform quality, clean and free from foreignmaterials. It shall be of uniform softness and capable of being easily caulked ordriven. It shall conform to IS: 782 for caulking lead in all respects.1.12.2 The quantity of lead and spun yarn required for different sizes of C.I. pipes areas below:TABLE 1.20Diameter Lead per jointDepth of LeadJointYarn per jointMm Kg mm Kg80 1.8 45 0.10100 2.2 45 0.18125 2.6 45 0.2150 3.4 50 0.22200 5.0 50 0.3250 6.1 50 0.35300 7.2 55 0.48350 8.4 55 0.60400 9.5 55 0.75450 14 55 0.95500 15 60 1600 19 60 1.2700 22 60 1.35750 25 60 1.45800 31.5 65 1.53900 35 65 1.881000 41 65 2.051.12.3. Lead shall be heated in a melting pot kept in easy reach of the joint to bepoured so that the molten metal will not be chilled in being carried from themelting pot to the joint and shall be brought to a proper temperature so thatwhen stirred it will show a rapid change of colour.1.12.3.1 Before pouring, all scum shall be removed. Each joint shall be made with onecontinuous pour filling of the entire joint space with solid lead. Spongy orimperfectly filled joints shall be burnt out and repoured.1.12.4 The joint runner shall fit snugly against the face of the socket and the outside ofthe pipe shall be dammed with clay to form a pouring lip to provide for filling thejoint flush with the face and to the top of the socket.1.12.5 The common form of joint is made by first caulking in spun yarn, then filling theremainder of the joint space by running in molten lead, taking care that nodross enters the joint, and then thoroughly caulking the lead. The lead need notextend into the joint further than the back of the groove formed in the socket.1.12.6 The spun yarn is used to centre the spigot in the socket, to prevent the flow ofmolten lead into the bore of the pipe, to reduce the amount of lead required tocomplete the joint to make the joint watertight, Spun yarn may become infectedwith bacteria, which may contaminate the water and, therefore, shall beeffectively disinfected before use.Urban Administration & Development Department Page 23
