STEAM INJECTION INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Maintenance procedures
1. Strainer: Inspect the screen at least twice during the first year.
If fouled, it should be inspected more frequently and cleaned
as needed.
2. Steam trap: At least twice a year, verify that the steam trap
is functioning properly. A blocked steam trap will be cold.
An improperly operating steam trap with steam exiting the
trap will be hot and noisy, and the discharge pipe from
it will be hot for a continuous distance up to 30' (9 m). A
properly operating steam trap will have about a 2 °F (1
°C) temperature drop measured across the trap from inlet to
discharge.
3. Valve (pneumatic): Inspect annually to ensure that:
a. The valve tightly closes off steam.
b. The stem packing is not leaking steam.
c. The diaphragm in the actuator is not leaking air.
Valve (electric modulating): Inspect annually to ensure that:
a. The valve operates freely.
b. The valve tightly closes off steam.
c. The stem packing is not leaking steam.
Valve (solenoid): Inspect annually to verify proper function
with steam-tight shutoff.
4. Silencer: Inspect at least annually for cleanliness. Clean or
replace as needed.
5. Teflon seal rings: After one year of service, verify that
rings are properly functioning. They require replacement if
disturbed, since the Teflon can take a “set” and not return to
its uncompressed shape.
6. O-rings (dispersion tube adapters): Replace after two or three
years of service.
7. Separator: No maintenance required.
8. Dispersion tube: No maintenance required.
