Before Assembly
    For small pipe size up to 4" IPS (115 mm), it is easier and more timesaving to apply the insulation before assembling the line. Just slip Aeroflex insulation tube over the pipe. The thick and smooth inner skin is coated with talcum powder for speeding up slipping even around most bends of the pipe. Apply brush coating of Aeroseal adhesive to set until non-tacky to the touch (approx., 5-15 minutes) then press the joints together firmly (see picture 1, 2 and 3).

Fittings
    Aeroflex insulation tube is easy to cut and fabricate for tees, elbows, crosses and almost any fitting forms on preassembled lines. Use a clean and sharp knife or electric knife to cut the insulation to the desired shape, depressing the insulation as little as possible to avoid irregular cuts. The commonly used fittings require only 45° and 90° cuts. A miter box will offer more accurate cuts.
A miter box will offer more accurate cuts but careful free-hand cuts are usually faster and more convenient on job-site installation. After fabricated fitting covers are done, snap fitting cover in place over a fitting and then apply brush coating of Aeroseal adhesive to all joint services. Allow the adhesive to set until non-tacky to the touch (approx. 5-15 minutes), press the joints together firmly.

For Existing Line
    To insulate existing lines, slit Aeroflex insulation tube lengthwise on one side, or use Aeroflex precut sheet for above 3" IPS (90 mm I.D.), and snap over the pipe Then seal lengthwise-slit surface and butt joints with Aeroseal adhesive. To assure a complete seal, avoiding loss of insulation efficiency, all joint surfaces must be fully and thinly coated with adhesive. Adhesive tape should not be used on seams and joints because tape is less effective than adhesive and may allow passage of moisture and air.

For Large Pipes and Irregular Shape
    All applications cannot be accomplished by preformed tubular insulation. The flexibility of Aeroflex insulation allows irregular curves and surfaces and surfaces of duct work, large piping, tanks and vessels. Cut the insulation sheet in a measured size with a clean sharp knife. Apply Aeroseal adhesive on both surfaces to be insulated. Allow the adhesive to set until non-tacky to the touch (5-15 minutes), press the sheet tightly against the surface to be insulated. Be sure it is in the desired position before the adhesive coated surface makes an initial contact since the adhesive forms an instant bond and repositioning after contact is difficult. Then seal both sheet rims with Aeroseal adhesive.
