Thermon SafeTrace Steam Tracers - Manual (Page 7)

INSTALLATION PROCEDURES
Inspection of System . . .
1. For ease of installation and maintainability, install
SafeTrace parallel to and in close contact with the process
piping. Secure the tracer to the piping on 300 mm inter-
vals. Space multiple tracers equally around the circumfer-
ence of the pipe.
2. Thoroughly inspect SafeTrace after installation is complete
to verify all bends are free of kinks and wrinkles and that
flattening has not occurred. Refer to the bending guide-
lines on page 3 of these installation procedures.
3. To prevent stress in the tubing, provide for expansion
where required. For long straight piping runs, a 300 mm
diameter expansion loop must be provided at 18 to 30 m
intervals. Tracer loops provided specifically for expansion
should not contain unions.
4. Properly terminate and seal all open ends of SafeTrace us-
ing the FAK-7 end seal kit and FAK-8 patch kit. Refer to the
illustrations on page 5.
5. Clean all tubing before it is connected. After all tracer
connections to the supply header and trap have been
completed, test the circuit for leaks by suitable hydrostatic
tests. Repair any leaks and retest the system prior to instal-
lation of the thermal insulation.
6. Refer to Illustration J for a typical installation of SafeTrace
on straight run piping and around elbows, flanges, valves
and pumps.
