Review the drawings or models for the pipe or equipment to be insulated. They will be identified with a double diamond, <><>. 2. The letter/number in the right hand diamond indicates the proper "Insulation Thickness Table". The number in the left hand diamond is the "thickness index" which indicates the insulation thickness in the in the "Insulation Thickness Table". The exception is when a single thickness is indicated such as found on ducts. In this case a cross is shown in the right hand diamond. 3. See the "Table of Contents" in front of the Specific at ion. 4. Note the numbered sections 2 thru 9. 5. Section 2 "Notes and Exceptions" provides data for Site areas or processes wh-ere special insulaton systems may be required. 6. Section 3 "Category" will assist Engineering, Construction and Plant Personnel in verifing that all pipe and equipment which must be insulated is included in the Specification. This Section is also helpfull for maintenance. 7. Section 4 "Material Index" is a list of approved insulation materials. Substitutes are not acceptable. 8. Section 5 "Thickness Index Tables" indicates the insulation material and thickness as shown in the double diamond. Where the insulation thickness index must be determined in the field, take the operating temperature in deg. F and add the number 460, then drop the last digit. Example; 300 deg F + 460 * 76 9. Sections 6,7 and 8 are the "Application Specifications". Review the "Table of Contents" for the correct Specification. 10. Section 9, the "Appendix" includes all sketches for fabrication details and additional supplemental Specifications.

Use a minimum of 1 gallon per 100 sf. Let coating dry before applying insulation. Do not apply sodium silicate to items that cannot be covered by" insulation on the same day. 6.1.4 Leave flanged joints un-insulated until connecting pipe and equipment has been hydrostatically tested by Du Pont, and released to the contractor for completion of insulation. 6.1.5 Steam tracer jumpers will be installed outside of the insulation at all flanged joints. 6.1.5.1 Cover steam tracer jumpers with 2" wide listing tape,(Code 992), spiral wrapped with 50Z overlap. Finish listing tape with a coat of insulation mastic, (Code 734). 6.1.6 Instrument tubing can be insulated as indicated in the previous paragraph. Where long tubing lines or severe weather conditions are anticipated, it is recommended to use the preinsulated tubing (Code DEF). 6.1.7 All fittings (flanges, valves, nozzles, drains, etc) are to be insulated (unless specifically excluded) with the same DUP 0838686 SPECIFICATION NO 8544 - VICTORIA Page 32 thickness as the adjacent piping. On screwed fittings, use insulation with same O.D. as adjacent pipe insulation. 6.1.8 At flanged joints, stop the insulation 1 bolt length plus 1" from the back of the flange. Do not bevel insulation. 6.1.9 See sketches in the Appendix for methods of installing and finishing removable insulation on hot and cold systems. 6.1.10 On piping where the insulation can get wet, install rain shields (Code 901) secured with nylon fasteners (Code 998) per Appendix B on horizontal lines where pipe hanger rods or pipe clamps penetrate top of insulation. Support all new lines outside the insulation jacket where possible with a 180 degree, 10 gage galvanized steel saddle (length to be 1.5 times the O.D. of the insulation). 6.1.11 Where protective guards or insulation is required for personnel protection follow these guide lines: 6.1.11.1 Guards are preferred instead of insulation for personnel protection where possible. 6.1.11.2 8 feet above floors, stairs, and regular working or travel platforms. 6.1.11 3 3 feet beyond the restrictions of plat forms, catwalks ', stairs, fixed ladders, or designated travel paths.

Eye and hand protection is required. This system is solvent free and therefore does not require special ventilation. 7.7.3 Procedure 7.7.3.1 This finish can be applied to polyisocyanurate foam-rigid, calcium silicate, cellular glass or mineral wool without any special preparation required. 7.7.3.2 When applying this finish to fiber glass -insulation it is recommended to lay a lightweight woven glass lagging cloth on the insulation in order to eliminate epoxy resin penetration. Precut a sufficient number of pieces of cloth and allow for a ` minimum of 1" overlap. 7.7.3.3 Fill cracks or openings in the insulation applying finish. before 7.7.3.4 For cold temperature systems, apply the epoxy resin directly over the mastic system when it has become dry. 7.7.3.5 This-system must be applied at temperatures above 32 F (0 C). For ease of application, when outdoor temperatures are below 50 F (10 C), keep epoxy in a warm area until ready for application. 7.7.3.6 The resin is a two-component mix with a pot-life of 20 to 60 minutes after mixing. Mix only the amount resin which can be readily applied. 7.7.3.7 For ease of handling, order material in containers no larger than one gallon. 7.7.4 Application 7.7.4.1 Cut the reinforcing cloth in lengths for ease of handling. Lay the sections of cloth directly on the insulation. Overlap adjoining sections of cloth by 2" min. Cloth can be pinned to the insulation. 7.7.4.2 Mix Alocit Thixotrope 28.96 with hardener (resin base coat) and apply directly to the surface of the cloth and insulation with a stiff bristled brush (cut bristles). DUP 0838709 SPECIFICATION NO 8544 VICTORIA Page 55 7.7.4.2.1 For large areas(10 square feet or greater), such as equipment heads, or where severe mechanical abuse or foot traffic is expected, use 6 x 6 or 8 x 8 reinforcing cloth with a resin base coat of 20 mils wet thickness (80 sq ft per gal.). 7.7.4.2.2 For small areas, and where only moderate abuse is expected, use 10 x 10 to 13 x 13 reinforcing cloth, with a resin b-ase coat of 10 mils wet thickness (160 sq ft per gal). 7.7.4.3 The base coat need not be dry prior to applying the brush application top coat of Alocit Aquacoat Adhesive 28.15. 7.7.4.4 The thickness of the top coat should be 10 mils wet thickness (160 sq ft./gal) for all applications. 7.7.4.5 When ordering Aquacoat Adhesive 28.15, specify desired color.
