 5            Protective jackets should be specified for pipe insulation exposed in food handling/kitchen
 6            areas, wet areas, exterior installations or where insulation is subject to physical abuse. Jackets
 7            also need to be specified for insulations other than elastomeric and polyolefin where not factory

11   EQUIPMENT INSULATION
12   Do not insulate over equipment access manholes, fittings, nameplates or ASME stamps. Bevel and seal
13   insulation at these locations.

15   SEMI-RIGID FIBERGLASS:
16   Apply insulation to equipment shells using weld pins, bonding adhesive, banded and wired in place. Fill all
17   joints, seams and depressions with insulating cement to a smooth, even surface. Cover with reinforcing
18   fabric and 2 coats of mastic. . Use vapor barrier mastic on systems requiring a vapor barrier.

20   ELASTOMERIC/POLYOLEFIN:
21   Apply full cover coat of adhesive to surface to be insulated, insulation and edge butt joints. Place insulation
22   with edge joints firmly butted pressing to surface for full adhesion. Seal seams and joints vapor tight.
