E3 Figure 1 power assembly of most 4"-24" pipes (See Figure 1 and specify pipe sizes involved). The joints may normally be disassem- bled in a similar manner, reversing the direction of the pull with the choker cable (Photo 4). It is also sometimes helpful to use rebating or wiggling deflection to aid in the disassembly of push -on joint pipes, par- ticularly when pipes have been installed for some time prior to removal. Photo 4 Large pipes are most often readily pushed or pulled together with heavy exca- vating/earth moving equipment available on - site (see page 2-14). In cases where assembly of pipes by manpower is desired, AMERICAN can provide special assembly tools and rigging which can be used for assembling most pipes of all sizes (Photo 5). These tools consist of a heavy-duty roller chain hoist, a steel pipe -end hook and snatch block, and associated wire s 4 Photo 5 2-12 rope and chain tackle (Photo 5) to attach all the rigging together to effect "double line" assembly from the top of the pipe (Photo 6). The snatch block pulley and twin line rigging approximately doubles the assembly force from the strong come - along, making possi- ble the assembly of up to 64" full-length pipe joints from the top of the pipe (Photo 7). Fittings and Short Photo 6 Pipes Push -on fitting or Photo 7 short pipe joint assembly is basically the same as that of standard length pipe, though special rigging may be necessary to hold these short items reasonably stable for assembly. See also Push -On Fittings Assembly Instructions in Section 4. Field Rounding Occasionally, field rounding of pipe ends may be necessary to accomplish assembly, particularly when large -diameter pipes are cut to be assembled into mechanical joints or couplings. Need for rounding in assembly of mechanical or stuffing -box -type joints can be predetermined by a difficulty in sliding the gland or end ring over the end of the pipe. Rounding may be accomplished in the fol- lowing manner using a mechanical jack and shaped blocks. (Note: This procedure may also be used with the assemblies involving push -on joint pipe, fittings, valves, etc.; how- ever, rounding is less frequently necessary for assembly of push -on joints.)
