15) TECHNICAL REQUIREMENTS:

General:

The Contractor shall provide all supervision, labor, equipment, parts, and materials to cut out failed steel steam and condensate piping and replace with new steel pipe and fittings. This work is located outside of building 91 in the main steam pit and is classified as a “CONFINED SPACE”. This steam pit is constructed of cast in place concrete walls and floor with a wood framed roof with three access hatches. This pit is approximately 8 feet into the ground.

This work will be performed outside of Building 91 (Boiler House) and is located at USCG Base Elizabeth City, NC. Building 91 is the main steam plant for the Industrial buildings located at the eastern end of Base Elizabeth City.

The existing steel piping inside the pit has failed at several points due to age and condition. The Boiler plant operates at 30 PSI maximum steam pressure. The steam piping to be replaced is 8-inch steel welded pipe and fittings. The steam condensate piping is 4 inch & 6 inch, including a 1-inch condensate piping arrangement with wye strainer, steam trap, isolation valves. This 1-inch condensate piping connects to a 2-inch drip leg located on the bottom of the main steam pipe to the condensate return pipe.

Approximate Steel Pipe and fittings (150#) to be replaced.

• 10 feet- 8-inch schedule 40 steel pipe

• 1 each- 8-inch sch. 40 90 deg. ell

• 1 each – 8-inch sch. 40 45 deg ell

• 4 each- 8-inch flanges, bolts, and gasket sets

• 10 feet – 6-inch schedule 40 steel pipe

• 1 each- 6-inch flange, bolts, and gasket sets

• 2 each- 6-inch sch. 40, 90-degree ell

• Misc.- 1 inch sch. 40 steel pipe, wye strainer, isolation valves, steam trap, unions, etc.

E. The Contractor shall remove all existing pipe insulation inside the steam pit so that all pipes may be visually inspected for condition. The existing pipe insulation is covered with aluminum corrugated all service jacket. The Contractor shall provide and install new pipe insulation of equivalent rating value and type of what was removed including corrugated aluminum all service jacket on all piping inside the steam pit.

F. The Contractor shall make connection of the new steam and condensate piping to the existing main flanged valves located inside the steam pit using, new flanged connections, including new flange gaskets, flange bolts, washers, and all fasteners required to make the piping system fully functionable and leak free.
