Figure 12: Hydraulic Draw-Up Sections
Figure 13: Boiler Section Assembly
a. STEAM BOILERS: The assembled boiler must
be subjected to a hydrostatic test of 45 psig to 55
psig.
b. HOT WATER BOILERS: The assembled boiler
must be subjected to a hydrostatic test of not less
than 1½ times the maximum allowable working
pressure, as established by the relief valve
provided with the boiler. For example, a boiler
with a 50 psi relief valve must be subjected to a
test pressure of 75 psig to 85 psig.
WARNING
Failure to properly hydrotest all boilers at the
correct pressure may result in section assembly
failure in operation.
4. EXAMINE BOILER CAREFULLY, INSIDE AND
OUTSIDE, to insure against leaks from cocked
nipples or through concealed breakage caused in
shipping and handling. This precaution is for your
protection and will simplify handling of necessary
replacements and adjustment claims.
5. After making certain that there are no leaks, drain
boiler and remove plugs for boiler trim and other
connections.
