3.1.3.3
Gratings, Pipe Railings, and Pit Covers
Apply a pre-treatment coating to gratings, pipe railings, pit covers, and
similar plant appurtenances to a dry film thickness of 0.008 to 0.013 mm
0.3 to 0.5 mil. After installation, touch up damaged surfaces with then
paint with two coats of finish paint matching type and color of adjacent
areas. Do not paint zinc-coated surfaces.
3.1.4
Boiler Cleaning
After installation, [the] [each] boiler shall be boiled out, under
supervision of the manufacturer, with soda ash or equivalent solution to
clean internal surfaces of oil, grease, mill scale, and dirt. Following
treatment, the boiler(s) shall be flushed, drained and then opened and
washed down and inspected to ensure that no traces of oil or foreign matter
are present. The boiler and associated piping shall then be drained and
refilled with treated softened water. At all times after initial cleaning,
the Contractor shall protect the boiler, tanks, and piping against internal
corrosion until testing is completed and the boiler(s) [is] [are] accepted.
Provide chemicals, labor for introducing chemicals, and professional
services for control and supervision of the treatment process.
3.1.5
Piping
Material and installation requirements including welding shall be as
specified in Section 15195N NATURAL GAS AND LIQUID PETROLEUM PIPING,
Section 15192N FUEL OIL PIPING, and Section 15183N STEAM SYSTEM AND
TERMINAL UNITS.
3.2
FIELD QUALITY CONTROL
Perform inspections and tests as specified herein to demonstrate that the
boiler(s) and auxiliary equipment, as installed, are in compliance with
contract requirements. During boiler system start-up tests,
factory-trained engineers or technicians employed by individual suppliers
of such components as the burner, flame safeguard and combustion controls,
feedwater treatment equipment, and other auxiliary equipment shall be
present, as required, to ensure the proper functioning, adjustment, and
testing of individual components and systems. No bypassing, use of
jumpers, or other disablement of control systems will be allowed unless
specified elsewhere. Labor, equipment, fuel, and test apparatus required
for testing shall be furnished by the Contractor. Rectify defects
disclosed by the tests by the Contractor within time period specified by
the Contracting Officer.
3.2.1
Inspections and Test
**************************************************************************
NOTE: These field tests shall not be mandatory for
all size boilers but shall be employed where advis
able due to largeness, type, or complexity of boiler
plant. The designer shall determine, on a case by
case basis, which tests are appropriate.
**************************************************************************
Make inspections and tests at the site under the direction of and subject
to the approval of the Contracting Officer. The Contractor shall operate
[the] [each] boiler and appurtenances prior to final testing and shall
ensure that necessary adjustments have been made. A [24-] [48-] [_____]
