Insulation Conduit and Underground American Gilsonite Company Salt Lake City, Utah An affiliate of Barber Oil Corp. & Standard Oil Co. of California ULATE TRIPLE-ZONE INSULATION Gilsulate is a unique solidified hydro carbon of high resin content which in granular form is poured directly around 7. Requires no mixing or special han dling 8. Can't be punctured, obviating need . to remove rocks from backfill hot underground pipes for insulation 9. Only normal pipe spacing required; and corrosion-protection. *' steam and condensate lines can run y side by side GENERAL DATA - , 1. Low cost per installed linear foot 2. Easy-to-use: pour . . . tamp . . tj/10. Pipe expands and contracts within Gilsulate structure r. ill. Makes repairs to the pipe quick, easy and economical normal pipe heat does the rest ^GRADES AND TEMPERATURE 3. Euses itself in hours into 3 zones/of GRANGES typeA............................... 220F to 300F permanent protection for'.the- pipe Type B............................... 300F to 385F against all commonly-encountered1;1. -Type C............................... 385F to 520F buried-line conditions such as acids/ TRENCH SIZE alkalies, roots, water, and corrosion 4 in. to 22 in. wider than pipe diameter, 4. Tested and proved in actual use in 6 in. minimum backfill over the Gilsulate hundreds of new construction and replacement installations 5. Can be used under all multiple-pipe and cramped space conditions (see bed. EFFICIENCY Heat loss 8-12 per cent of bare pipe Inert to ordinary acids and alkalies found in soil, excellent dielectric illus. below) 6.

J. 1646 Insulation Conduit and Underground Durant Insulated Pipe Company Palo Alto, California Durant International Corporation Williamstown, New Jersey REPRESENTATIVES IN PRINCIPAL CITIES AND CANADA DURANT Pre-Sealed INSULATED PIPE Cutaway shows DURANT construction--Insulation and support sections are ap plied next to pipe--heavy gage galvanized steel casing is slipped over load bearing and spacer sections leaving a minimum 1 in. space, which is filled with a special high melting point, non-porous asphalt. The result is a solid, compact unit, per manently waterproofed. DURANT INSULATED PIPE is pre-fabricated into complete, insulated and water proofed systems for use in underground or exposed locations. DIP is used for the conveyance of steam, hot water, refrigerants and process fluids, and for tracer type systems. DIP is fabricated in all standard sizes--Pipe and Insulation supplied as specified-- and is equally adaptable to single or multiple pipe units. SPECIAL FEATURES The DURANT patented insulated anchor eliminates contact between pipe and anchor plate--provides electrical and thermostatic insulation against heat loss and electrolytic action. Assembly and installation of DIP units consists of joining pipe--applying insulation around pipe joint--securing connector to conduit ends--filling 1 in. space between insulation and connector with DIP special asphalt. Units may be assembled before placing in trench as shown here. No slabs, drains or supports are necessary.
