Water Piping Connections
All CDHF units, "A" and later design
sequences, use grooved-pipe
connections. (See Table 5). These are
cut-groove end NSP (Victaulic
pipe connection .
Flanged connections for 300 PSI
waterboxes use welded flanges.
Piping joined using grooved type
couplings, like all types of piping
systems, requires proper support to
carry the weight of pipes and
equipment.
The support methods used must
eliminate undue stresses on joints,
piping and other components; allow
movement where required, and
provide for any other special
requirements (i.e., drainage, etc.).
