Steam Piping Installation
1. Set and anchor dryer in position. Machine should be level to
assure proper steam circulation.
2. To prevent condensate draining from headers to dryer, piping
should have a minimum 12” above respective header. Do not
make steam connection to header with a horizontal or
downwardly facing tee or elbow.
3. Whenever possible, horizontal runs of steam lines must drain,
by gravity, to respective steam header. Water pockets, or an
improperly drained steam header will provide wet steam,
causing improper operation of dryer. If pockets or improper
drainage cannot be eliminated, install a bypass trap to drain
condensate from the low point in the steam supply header to
the return.
4. In both steam supply and steam return line, it is recommended
that each have a 3/4” union and 3/4” globe valve. This will
enable you to disconnect the steam connections and service
the dryer while your plant is in operation.
5. Before connecting trap and check valve to dryer, open globe
valve in steam supply line and allow steam to flow through
dryer to flush out any dirt and scale from dryer. This will
assure proper operation of trap when connected.
6. After flushing system, install bucket trap (with built-in
strainer) and check valve. For successful operation of dryer,
install trap 18" below coil and as near to the dryer as
possible. Inspect trap carefully for inlet and outlet markings
and install according to trap manufacturer’s instructions. If
steam is gravity returned to boiler, omit trap but install check
valve in return line near dryer.
7. Install union and globe valve in return line and make final
pipe connections to return header.
1. Trap each dryer individually. Always keep the trap clean and
in good working condition.
2. When dryer is on the end of a line of equipment, extend
header at least 4 feet beyond dryer. Install globe valve, union,
check valve and bypass trap at end of line. If gravity returned
to boiler, omit trap.
3. Insulate steam supply and return line for safety of
operator and safety while servicing dryer.
4. Keep dryer in good working condition. Repair or replace any
worn or defective parts.
