PART 3 EXECUTION

EXAMINATION

Verify that piping has been tested before applying insulation materials.

Verify that surfaces are clean, foreign material removed, and dry.

INSTALLATION

Install materials in accordance with manufacturer's instructions.

On exposed piping, locate insulation and cover seams in least visible locations.

Insulated dual temperature pipes or cold pipes conveying fluids below ambient temperature:

Provide vapor barrier jackets, factory applied or field applied.

Insulate fittings, joints, and valves with molded insulation of like material and thickness as adjacent pipe.

Finish with glass cloth and vapor barrier adhesive.

PVC fitting covers may be used.

Continue insulation through walls, sleeves, pipe hangers, and other pipe penetrations.

Insulate entire system including fittings, valves, unions, flanges, strainers, flexible connections, [pump bodies,] and expansion joints.

For insulated pipes conveying fluids above ambient temperature:

Provide standard jackets, with or without vapor barrier, factory applied or field applied.

Insulate fittings, joints, and valves with insulation of like material and thickness as adjoining pipe.

Finish with glass cloth and adhesive.

PVC fitting covers may be used.

For hot piping conveying fluids [140] [____] degrees F ([60] [___-_] degrees C) or less, do not insulate flanges and unions at equipment, but bevel and seal ends of insulation.

For hot piping conveying fluids over [140] [____] degrees F ([60] [____] degrees C), insulate flanges and unions at equipment.

Inserts and Shields:

Application:	Piping [1-1/2] [2] [___] inches ([40] [50] [___] mm) diameter or larger.

Shields:	[Galvanized] steel between pipe hangers or pipe hanger rolls and inserts.

Insert Location:	Between support shield and piping and under the finish jacket.

Insert Configuration: Minimum 6 inches (150 mm) long, of same thickness and contour as adjoining insulation; may be factory fabricated.

Insert Material:	[ASTM C640 cork] [hydrous calcium silicate insulation] [or other heavy density insulating material suitable for the planned temperature range].

Finish insulation at supports, protrusions, and interruptions.

For pipe exposed in mechanical equipment rooms or in finished spaces [below 10 feet (3 meters) above finished floor], finish with [canvas jacket sized for finish painting] [PVC jacket and fitting covers] [ABS jacket and fitting covers] [aluminum jacket] [stainless steel jacket].

For exterior applications, provide vapor barrier jacket. Insulate fittings, joints, and valves with insulation of like material and thickness as adjoining pipe, and finish with glass mesh reinforced vapor barrier cement. Cover with [aluminum] [stainless steel] jacket with seams located on bottom side of horizontal piping.

For buried piping, provide factory fabricated assembly with inner all-purpose service jacket with self sealing lap, and asphalt impregnated open mesh glass fabric, with one mil (0.025 mm) thick aluminum foil sandwiched between three layers of bituminous compound; outer surface faced with a polyester film.

For heat traced piping, insulate fittings, joints, and valves with insulation of like material, thickness, and finish as adjoining pipe. Size large enough to enclose pipe and heat tracer. Cover with [aluminum] [stainless steel] jacket with seams located on bottom side of horizontal piping.

TOLERANCE

Substituted insulation materials shall provide thermal resistance within 10 percent at normal conditions, as materials indicated.
