3.2.1.1
Hydrostatic and Leak Tightness Tests
a.
Test piping systems attached to the boilers and included under the
jurisdiction of ASME BPVC SEC I in accordance with the requirement
of that Code. Piping bearing ASME Code symbol stamp will be
accepted only as indicating compliance with the design and
material requirements of the code.
b.
Test piping which is a part of the steam generation or auxiliary
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 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. Examine 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 each test, 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 in operation equipment
provided by the Contractor, 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 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
the manufacturer's recommendations. Replace bearings that run
roughly or noisily.
