PART 3 EXECUTION

EXAMINATION

Verify that equipment 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.

Do not insulate factory insulated equipment.

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

Apply insulation close to equipment by grooving, scoring, and bevelling insulation. Secure insulation to equipment with studs, pins, clips, adhesive, wires, or bands.

Fill joints, cracks, seams, and depressions with bedding compound to form smooth surface. On cold equipment, use vapour barrier cement.

Insulated dual temperature equipment or cold equipment containing fluids below ambient temperature:

Provide vapor barrier jackets, factory applied or field applied.

Finish with glass cloth and vapor barrier adhesive.

Insulate entire system.

For insulated equipment containing fluids above ambient temperature:

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

Finish with glass cloth and adhesive.

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

For hot equipment containing fluids over [140] [____] degrees F ([60] [____] degrees C), insulate flanges and unions with removable sections and jackets.

Inserts and Shields:

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

Shields: [galvanized] steel between hangers and inserts.

Insert location: between support shield and equipment 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 equipment in mechanical equipment rooms or in finished spaces, finish with [canvas jacket sized for finish painting] [PVC jacket and fitting covers] [aluminum

jacket] [stainless steel jacket].

For exterior applications, provide vapor barrier jacket or finish with glass mesh reinforced vapor barrier cement. Cover with [aluminum] [stainless steel] jacket with seams located on bottom side of horizontal equipment.

Cover [glass fiber] [cellular glass] [hydrous calcium silicate] [cellular foam] insulation with [metal mesh and finish with heavy coat of insulating cement] [aluminum jacket] [stainless steel jacket].

Do not insulate over nameplate or ASME stamps. Bevel and seal insulation around such.

Install insulation for equipment requiring access for maintenance, repair, or cleaning, in such a manner that it can be easily removed and replaced without damage.

TOLERANCE

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