c. Install the pipe using chain tongs.
Figure 15 shows the proper method of
applying chain tongs to the flange.
Thereby most of the force is exerted on
the upper flange rather than the on the
discharge housing or the non-return
valve.
Apply torque approximating the values
given in Table 5.
CAUTION The discharge section may require
modification to provide protective
clearance to the flat cable and
splice which will be mounted later
on the riser pipe just above the
pump.
