3 Maintenance
3.0 Remove the seal cooler from service.
3.1 Remove all end fittings connected to the lengths of tubing protruding from each end
of the cooler. Fitting ferrules and nuts cannot be removed from the primary lengths
of protruding tube and should be remain in place. Do not remove the fittings directly
adjacent to the tube cover. Be sure to retain all fittings and mark them appropriately.
This will minimize the likelihood of fitting leaks upon reassembly.
3.2 Remove the center bolt.
3.3 Remove each of the four snap rings located near each tube to end cover fitting.
3.4 Carefully pry each end cover from the main cooler body. A short piece of pipe
(6 or 8 inch) screwed into the shell side inlet or outlet offers an adequate amount of
leverage. Take care not to use too much force, which can result in coil stretch. The
outer and inner shells can now be removed, which will expose the coiled tubing.
3.5 Remove the sheet metal baffles located at the tube body OD and ID. Orientation is
important and should be recorded.
3.6 Clean the shell and coils taking care not to damage either.
3.7 Inspect all components for damage or corrosion and replace as needed. Secondary
sealing components such as O-rings should always be replaced.
3.8 Reassemble the unit in reverse of disassembly. Center bolt torque required is
100 to 150 ft-lbf. All fittings should be reassembled to the manufacturer’s specifications.
3.9 Leak testing is recommended after assembly. Refer to end user specifications or
procedures. Alternately, individual units can be returned to Flowserve for
refurbishment and testing.
