6017 Series Hot Oil Large Temperature Control Units Page 21
The following table lists 6017 TCU pipe sizes.
Connections for TO PROCESS and FROM PROCESS lines are:
• 2" NPT (50.8 mm) at 90 gpm (341 lpm)
• 2-1/2" NPT (63.5 mm) at 150 gpm (568 lpm)
• 3" NPT (76.2 mm) at 200 gpm (757 lpm)
Water connections for COOLING WATER SUPPLY and
COOLING WATER DRAIN are:
• ¾” NPT (19.1 mm) for 3.9 & 6.7 sq. ft. heat exchangers.
• 1" NPT (25.4 mm) for 13, 21, & 27 sq. ft. heat exchangers.
The customer is responsible for conversions to metric standards.
Notes: Always use a backup wrench to support 6017 unit piping
when making connections. Make sure all external piping is
supported independently of the 6017 unit.
Sterling, Inc. recommends that you have strainers installed
on the cooling water inlets and customer-supplied shut-off
valves on all piping connections. Use common black
welded pipe for permanent installations.
The 6017 is designed to operate with an open, unrestricted
drain line. Steam rapidly expands within the heat
exchanger, so any overpressure condition from
backpressure or standing columns of water against the
drain must be avoided.
If you must use a pipe joint compound, use a compound that can
withstand the high temperatures and pressures of your 6017 unit.
Always insulate all piping to prevent burn hazards and to retain
heat. Make sure insulation is properly rated for maximum
operating temperatures of your 6017 unit.
Piping Considerations for Mobile Installations
Because your 6017 unit is not fitted with casters, it should be
secured to the floor with the appropriate hardware. You can
purchase high-quality flexible metal hose from Sterling/Sterlco to
allow for thermal expansion of the process piping; state the length
you want when ordering.
