systems, including piping within the boiler room and external to
the boiler room, by the following methods:
(1) Perform hydrostatic test at 150 percent of design pressure
for welded and screwed steel piping systems except those for air,
oil, and gas. Hold hydrostatic tests for a period of one hour
with no pressure loss. Temperature of the testing fluid shall not
exceed 38 degrees C 100 degrees F.
(2) Test air and oil lines in accordance with the requirements of
ASME B31.1 for pneumatic tests with the exception that the test
pressure must be held for one hour. Examination for leaks by a
soap or other foaming agent test.
(3) Inspection and test of gas piping shall conform to the
requirements of ANSI Z223.1.
c.
For tests install a calibrated test pressure gage in the system to
observe loss in pressure.
3.2.2
Preliminary Operation
The Contractor under the direction of the respective manufacturer's
representative shall perform the work of placing into operation equipment
provided except as specifically noted otherwise. Make adjustments to
equipment that are necessary to ensure proper operation as instructed by
the manufacturer of the equipment.
a.
Lubricate equipment prior to operation in accordance with the
manufacturer's instructions. Lubricants shall be provided by the
Contractor. Contractor shall furnish lubrication gun with spare
cartridges of lubricant to operating personnel.
b.
Dry out motors before operation as required to develop and
maintain proper and constant insulation resistance.
c.
Check drive equipment couplings for proper alignment at both
ambient and operating temperature conditions.
3.2.3
General Startup Requirements
Prior to initial operation of any complete system, check each component as
follows:
a.
Inspect bearings for cleanliness and alignment and remove foreign
materials found. Lubricate as necessary and in accordance with
manufacturer's recommendations. Replace bearings that run roughly
or noisily.
b.
Adjust direct drives for proper alignment of flexible couplings.
Provide lubrication when a particular coupling so requires. Check
security of couplings to driver shafts. Set drive components to
ensure free rotation with no undesirable stresses present on the
coupling of attached equipment.
c.
Check motors for amperage comparison to nameplate value. Correct
conditions that produce excessive current flow and that exist due
to equipment malfunction.
