Piping and Connection
Support all piping independently of the coils.
Provide swing joints or flexible fittings in all connections
that are adjacent heating coils in order to absorb thermal
expansion and contraction strains.
When attaching piping to the coil header, make the
connection only tight enough to prevent leaks, the
maximum recommended torque is
200ft-lbs.
Teflon tape or teflon piping compound should not be used
because of its high lubricity, teflon makes it easier to
tighten the pipe to the header joint past the point where an
effective seal is created, thus damage to the coil could
result.
“White Zinc” compound / pipe sealer on all threaded
connection is recommended, instead.
Typical Piping for Water Coil.

Chilled Water Piping – Coil
Connection
General Coil Piping Recommendation Refer to Figure 15 & 17
for typical cooling / heating and steam coil piping.
Proper installation, piping and trapping is necessary to assure
satisfactory coil operation and to prevent operational damage.
Water inlet and outlet connections protrude through the coil
section side panel. Follow standard piping practices when
piping to the coil. Note the following:
1.
2.
3.
4.
5.
NOTE : DRAINS AND VENT CONNECTIONs ARE
PROVIDED AS STANDARD ON COIL HEADERS.
IF EXTENDED DRAINS AND VENTS ARE REQUIRED,
THEY MUST BE FIELD PROVIDED.
IMPORTANT
To avoid damaging the coil connections it is essential to
grip the pipe connection whilst applying counter
pressure to tighten the joint (see Figure 16).
Use “Back-up wrench” when attaching piping to coils,
on threaded connections.
AV - Automatic or
manual air vent
MV - Magnetic valve
GV - Gate valve

Complety stress-free are
essential. The pipework of
the coils should be arranged
to facilutate easy removeal of
the coil for any required
maintenance purposes.
