Insulation SXtinndd The Ric-wiL Company PREFABRICATED INSULATED PIPING SYSTEMS Union Commerce Bldg., Cleveland, Ohio Agents in Principal Cities Ric-wiL produces complete insulated piping systems designed and engineered to specific operating requirements for transmission (with the lowest possible thermal loss) of steam, hot or refrigerated liquids or gases. Insulated Pipe Unit Single or Multiple Pipes Prefabricated units with single or any specified combination of pipes, in com- ' plete sealed 21-ft sections. Helical corru gated conduit, asphalt and phenolicrosin coated, wrapped with asphalt saturated asbestos felt. Cast-Iron Insu lated Pipe. Units Prefabricated units for underground insulated piping systems where perma nency and thoroughly tight joints are desired. Pipe and insulation are housed in heavy cast iron conduit--standard unit 18 ft 6 in. long, with accessories as required. FoUelad Pipe Units For Over head Lines Pipe and insulation protected by a double coat of machine applied high tem perature asphalt. Additional insulation and protection are given by a wrapping of asbestos felt and spiral wrapping of copper or aluminum foil. Standard THe Conduit (Sectional) Super-Tile Conduit (Sectional) Cast-Iron Conduit (Sectional) Vitrified and glazed A.S.T.M. Stand ard Tile housing--acid and weather proof. Foundation type drain supporting pipe with correctly engineered pipe sup port. For single or multiple pipe system-- sectional pipe covering or filler type insulation. Similar to Standard Tile but with double-strength walls for heavy overhead loads. Will support Btatic load of 6 tons per wheel under actual installed conditions. Heavy duty tile base drain. \ Heavy duty reinforced cast iron con duit for use in shallow underground in stallation close to or under rail traffic. Durable watertight vibration proof clamps insure tightness. ` TUe ConduitUniversal Type (Sectional) For use where installation conditions require concrete pads. Side walls are double-cell vitrified trapezoidal design. Arch may be Standard Tile, Super Tile or Cast Iron.

GENERAL DATA The improved ZCRETE system of underground insula tion is a field fabrication adaptable to any size, number or arrangement of pipes. Six inches of insulation is ordi narily used on the outside of all pipes. A minimum of four inches is economical spacing between piping. The strength and water resistance of Z-CRETE in sulation serves as a monolithic, jointless insulating filler around pipes. A curing and waterproofing membrane completes the installation. Z-CRETE installations have no joints to leak heat or collect water--they are as permanent as the earth itself. Anchors, guides and expansion devices (except loops) are the same as used in conven tional systems. The curing membrane provides external water protection and imparts a tensile strength to the conduit. -- MEMBRANE tTRVCTVAM. . -Single Pipe Conduit Two Pipe Conduit Multiple Pipe Conduit TYPICAL Z-CRETE CONDUITS Commonly used installations of Z-CRETE are shown above. The single pipe and double pipe conduit-consist of a structural concrete pad, pre-cast Z-CRETE support blocks on which the pipes rest, a pour of Z-CRETE insulating concrete and a curing and waterproofing membrane. The multiple pipe conduit at the right has a second pre-cast support for the upper group of pipes. REINSULATION OF EXISTING CONDUITS The ruinous effect;of water on steel pipe and insulation is well known. Z-CRETE insulation restricts moisture, keeps the conduit dry. Inorganic Z-CRETE con crete naturally resists deterioration. Most open boxes or voids may be filled with Z-CRETE insulation without using rollers, rods, etc. The mass of water re sistant Z-CRETE restricts the move ment of moisture, so special drainage provisions are not ordinarily required. Z-CRETE is sold and installed by licensed applicators of Zonolite Company under U. S. Patent No. 2355966--Cana dian Patent No. 439356. There is an ap plicator near you.
