b. The steam supply line to the dryer must include a 12-inch (30.48 cm) riser along with a drip trap and
check valve. This will prevent any condensate from entering the steam coil.
c. Flexible hoses or couplings
must be
used. The dryer vibrates slightly when it runs and this will cause
the steam coil connections to crack if they are hard piped to the supply and return mains.
d. Shutoff valves for each dryer
should be
installed in the supply, return, and drip trap return lines. This
will allow the dryer to be isolated from the supply and return mains if the dryer needs maintenance
work.
e. Install an inverted bucket steam trap, which will pass 2,700 lb (1224.69 kg) at 125 psi (8.61 bar) and
check valve for each unit at least 12-inches (30.48 cm) below steam coil as close to the coil as possible.
f. The supply and return lines
should be
insulated. This will save energy and provide for safety of the
operator and maintenance personnel.
g. Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly
causing coil damage.
ALL
horizontal runs of steam supply piping
should be
pitched 1/4-inch
(6.35 mm) for every 1 foot (0.30 meters) back towards the steam supply header causing any condensate
in the line to drain the header. Install a bypass trap in any low point to eliminate wet steam.
