be fitted with sleeves. Each sleeve shall be of sufficient length to pass
through the entire thickness of the associated structural member and shall
be large enough to provide a minimum clear distance of 13 mm 1/2 inch
between the pipe and sleeve, except where otherwise indicated. Sleeves
through concrete may be 0.912 mm (20 gauge) 20 gauge metal, fiber, or other
approved material. Sleeves shall be accurately located on center with the
piping and shall be securely fastened in place. The space between the
sleeves and the pipe shall be caulked and filled with bituminous plastic
cement or mechanical caulking units designed for such use.

FIELD PAINTING AND COATING
**************************************************************************
NOTE: Where identification of piping is required by
the using service, this paragraph will be amplified
to include appropriate requirements either directly
or by reference to a separate section. Air Force
requirements are covered in AFM 88-15.
**************************************************************************
Except as otherwise specified, ferrous metal shall be cleaned, prepared,
and painted as specified in Section 09900 PAINTS AND COATINGS. Buried
steel shall be given a protective coating as specified. Exposed pipe
covering shall be painted as specified in Section 09900 PAINTS AND
COATINGS. Aluminum sheath over insulation shall not be painted.

TESTS
**************************************************************************
NOTE: Before occupancy of a facility the boilers
shall be inspected in accordance with the Code of
Boiler and Pressure Vessel Inspectors (BPVI) and the
American Society of Mechanical Engineers (ASME).
Inspectors must be certified in accordance with BPVI
standards.
**************************************************************************
The Contractor shall submit the proposed performance test procedure for
required tests, 30 days prior to the proposed test date, containing a
complete description of the proposed test, along with calibration curves or
test results furnished by an independent testing laboratory of each
instrument, meter, gauge, and thermometer to be used in the tests. The
test shall not commence until the procedure has been approved. The
Contractor's complete plan for water treatment, including proposed
chemicals to be used and nationally recognized testing codes applicable to
the system, shall be submitted prior to system startup.
3.7.1
Following erection, each HTW generator shall be tested hydrostatically and
proved tight under a gauge pressure of 1.5 times the specified working
pressure. Following the installation of all piping and boiler house
equipment, but before the application of any insulation, hydrostatic tests
shall be made and the system proved tight under gauge pressures of 1.5
times the specified working pressure. Tests shall be made under the
direction of, and subject to, the approval of the Contracting Officer. The
Contractor shall adjust all equipment and controls before the scheduled
operational test. A testing schedule shall be submitted at least 15 days
before scheduled test.
