Sinceiely, Giibeit Gently Secietaiy GG/phl Enclcsuae CAPCO JEN 0020558 SECTION 3 S should be taken not to reverse the gasket when placed in the bell. Each pipe joint shall be sealed with a cou pling consoling of an asbestos-cement sleeve and two rubber rings or an equivalent coupling or joint of equiv alent strength and performance. The pipe joint shall not be deflected either vertically or horizontally beyond the limits recommended by the manufac turer. j 3.3.2.1 When pipelaying is not in progress, the open ends of installed pipe shall be closed to prevent entrance of trench water into the line. 3.3.2.2 Whenever water is excluded from the interior of the pipe, enough backfill shall be placed on the pipe to prevent floatation. Any pipe that has floated shall be removed from the trench and the bedding corrected to conform to paragraph 3.2.3. No pipe shall be laid when the weather is un y suitable for proper installation as deter mined by the engineer. 3.3.3 Pipe cutting. Pipe-cutting methods that produce a smooth, square cut end without damage to the pipe and that minimize or eliminate airborne particles shall be employed. Rotating blades, hand saws, or similar materials, when properly used, are acceptable. Abrasive disks are not recommended unless special precautions are taken. 3.3.4 End preparation. Whenever it is necessary to cut a length of pipe in the field, the end shall he prepared as follows: 3.3.4.1 The pipe end of random lengths shall be machined by commer cially available field lathes designed for this purpose to ensure that the diam eter, profile, and roundness meet the pipe manufacturer's specifications. The machined surface on which the com y pression ring seals shall be smooth and cylindrical to ensure joint integrity. 3.3.4.2 The pipe end of machined overall lengths shall be beveled in ac cordance with the pipe manufacturer's specifications. 3.3.5 Length of pipe at fittings and rigid structures. When rigid joints are formed by caulked materials or by bolts with rubber ring seals, such as at fit tings, the length of 8-in. diameter and smaller pipe fitted into the bell of the fittings shall not exceed 3 ft 3 in. and the length of 10-in. diameter and larger pipe shall not exceed 6 ft 6 in. At least one flexible joint shall " be used between two adjacent rigid joints. A coupling shall be cast in the wall of rigid structures at the point of entry of pipelines to provide flexibility at the wall. To provide additional flexibility, the pipe at the point of entry shall have a laying length of not more than 6 ft 6 in. Sec. 3.4 Jointing of Pipe to Valves, Hydrants, and Fittings 3.4.1 General. Each valve, hydrant, or fitting connected to asbestos-cement pipe shall either be equipped with a hell of an inside diameter large enough to receive the pipe and caulking of at least J -in. thickness around the full circumference of the pipe, or shall have a profile that permits a seal to be made between the machined pipe and the bell of the fitting with a rubber ring. 3.4.1.1 Before valves, hydrants, or fittings are find, all lumps, blisters, and excess coating shall be removed from the bell. The inside of the bell shall then be wire-brushed and both the in side of the bell and the spigot end of the pipe shall be wiped clean and dry. All surfaces to be jointed shall be kept clean until the joints are made. 3.4.2 Push-on joints. The push-on joint is a single rubber-gasket joint.

The me 24-42 in. in diameter. chanical joint is a bolted joint of the 3.4.4.5 Lead for caulking purposes stuffing box type. In some sizes and shall meet the current requirements of classes, an adaptor is required between ASTM B29, "Standard Specifications the asbestos-cement pipe and the me for Pig Lead, in the Common Desilver chanical joint. The joints shall con ized Grade." form to the current revision of ANSI A21.ll (AWWA Clll), "Rubber- Gasket Joints for Cast-Iron and Duc Sec. 3.5 Setting of Hydrants, tile-Iron Pressure Pipe and Fittings," Valve*, and Fitting* and shall be assembled as required in Appendix A, Notes on Installation of Mechanical Joints, of that standard, 3.4.4 Poured joints. 3.4.4.1 The yarning or packing ma terial shall be as specified by the engi neer. It shall consist of molded rubber rings. Asbestos rope or treated paper rope may be used only with the ap proval of the engineer when the space 3.5.1 General. Hydrants, valves, and fittings shall be provided and in stalled as shown on the drawings or as specified in the supplementary specifi cations. They shall be inspected care fully and cleaned as required in para graph 3.4.1.1 prior to lowering into the trench. 3.5.2 Reaction or thrust backing.
