MIL-HDBK-1130
Piping, Structural Steel Framing, and Casings. Exposed metal
j)
surfaces on piping, structural steel framing, and casings
should be primed and painted.
Settings and Insulation. The interior of settings should be
k)
cleaned, and doors should be painted. To keep the materials in
settings and insulation dry, doors and all other openings
should be sealed carefully, and pans of quicklime should be
placed inside the setting.
Pulverizers, Feeders, and Exhausters. All bearing surfaces on
1)
pulverizers, feeders, and exhausters should be coated
thoroughly with rust-preventive oil or grease. With the
exception of unfinished surfaces of castings, all exposed metal
surfaces should be primed and painted.
Coal Pipes and Burners. Coal pipes and burners should be blown
m)
out with compressed air. Bearings and other finished surfaces
of burner dampers and vanes should be thoroughly greased.
Coal and Ash-Handling Equipment. Coal and ash-handling
n)
equipment should be cleaned, including weighing devices.
Running parts should be protected with grease, and exposed
metal surfaces should be primed and painted. Conveyor belts
should not be left under tension.
Feed-Water Heaters, Deaerators, Vent Condensers, Water-Heating
2.5.1.2
Equipment, Tanks, and Receivers. Feed-water heaters, deaerators, vent
condensers, water-heating equipment, tanks, and receivers should be drained
completely; take care to remove all water from trays, tubes, and coils. Silt,
scale, and lime should be removed; wire brushing may be necessary to eliminate
all corrosion blisters in tanks and receivers. Blowdown tanks should be
drained. Clean flues of all deposits of soot and carbon; remove and store
baffles. Heaters should be left open. All steam and water lines should be
drained, and openings capped or blanked off. Tightly cap vent pipes.
Overflow and oil traps should be thoroughly cleaned and reassembled.
Manholes, handholes, and cleanout doors should be left uncovered; all covers,
studs, bolts, nuts, and other loose parts should be coated with grease and
securely fastened in place at their respective openings to protect against
loss. The threads of tapped openings and machined surfaces, such as those on
valves and flanges, should be greased. Gauge glasses and thermometers should
be protected against breakage. The interiors of steel tanks, deaerators, vent
condensers, and heaters should be coated with corrosion-resistant paint; if
tanks may later be used for drinking water, the coating should be enamel
conforming to Navy Civil Engineering Laboratory (NCEL) Publication TDS 77-09,
Coating Interiors of Steel Potable Water Tanks, or applicable American Water
Works Association (AWWA) specifications.
