EXECUTION
3.1
HEAT RECOVERY EQUIPMENT AND AUXILIARIES
**************************************************************************
NOTE: All pertinent piping and related equipment
supports are to be designed and indicated in
accordance with TM 5-809-10 for seismic design.
**************************************************************************
3.1.1
Installation
All equipment shall be installed in accordance with manufacturer's
instructions and recommendation. All pieces of equipment shall be bolted
in place on foundations unless they are skid-mounted on the prime mover
base skid. Flexible connectors shall be used to connect any piping to the
prime mover. Piping for interconnecting various components of the heat
recovery equipment shall conform to the requirements of ASME B31.1. The
Contractor shall submit calculations as specified in the Submittals
paragraph.
3.1.2
Equipment Guards and Access
Belts, pulleys, chains, gears, couplings, projecting setscrews, keys, and
other rotating parts located where personnel contact is possible shall be
fully enclosed or guarded. High temperature equipment and piping located
within personnel contact or where a potential fire hazard exists shall be
properly guarded or covered with insulation of a type specified. Items
such as catwalks, operating platforms, ladders, and guardrails shall be
provided where shown and shall be constructed in accordance with Section
05500A MISCELLANEOUS METAL.
3.2
TESTS
3.2.1
Following installation, each boiler shall be tested hydrostatically and
proved tight under a gauge pressure of 1.5 times the working pressure
specified and in accordance with applicable ASME requirements. Following
the installation of piping and heat recovery 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 working pressure
specified, but not less than the following:
a.
Low-pressure lines
275 kPa
b.
Medium-pressure lines
415 kPa
c.
High-pressure-steam lines
1035 kPa
d.
Boiler feed lines
1550 kPa
a.
Low-pressure lines
40 psi
b.
Medium-pressure lines
60 psi
