Insulation Underground The Ric-wiL Company INSULATED PIPE CONDUIT SYSTEMS Union Commerce Bldg., Cleveland, Ohio Agents in Principal Cities There is a Ric-wiL insulated conduit system engineered to your specific needs--the transmission of steam, hot water, oil, hot or refrigerated process liquids--providing heat transfer with the lowest possible loss. 1. RIC-WIL INSULATED PIPE UNIT-SINGLE PIPE SYSTEM Prefabricated complete units--pipe as specified, thoroughly insulated, in helical corrugated conduit, coated and wrapped with asphalt saturated asbestos felt. 21-ft lengths for speedy installation. For underground or overhead systems. t RIC-WIL INSULATED PIPE UNIT-MULTIPLE PIPE SYSTEM Any specified combination of pipes in prefabricated conduit --insulated and protected the same as the single pipe system. Any or all of the pipe lines may be specially insulated to meet job requirements. 3. RIC-WIL INSULATED PIPE UNIT-FOR PROCESS LIQUIDS An adaptation of the multiple system used where a steam or hot water line heats fluids in other lines. Pipes are insulated from the exterior but not from each other. Sizes and specifications as required--conduit same as for other insulated pipe units. i RIC-WIL STANDARD TILE CONDUIT-TYPE F Vitrified glazed A.S.T.M. Standard Tile Housing--acid and waterproof--with foundation type base drain sup porting weight of piping through correctly engineered pipe supports. Positive locked-in-place cement seals on sides and ends. For single or multiple pipes. 5. RIC-WIL SUPER TILE CONDUIT-TYPE F Same advantages as Standard Tile but with walls approxi mately double thick for strength under heavy traffic or where overhead load is above normal. Will support con centrated static load of 6 tons per wheel under actual installation conditions. Base drain of extra-heavy tile. 6. RIC-WIL CAST IRON CONDUIT-TYPE F~ Heavy reinforced cast iron conduit for use where under ground pipe lines run close to or under railroad tracks. Durable, water-tight and vibration-proof. Positive lockedin-place cement seals on sides and ends with metal clamps for extra tightness. 7. RIC-WIL TILE CONDUIT-UNIVERSAL TYPE Where installation conditions dictate the use of a concrete pad Ric-wiL Universal Tile is recommended. Side walls are double-cell vitrified trapezoidal block design. Arch . may be Standard Tile, Super-Tile, or Cast Iron. 8. RIC-WIL TILE CONDUIT-TYPE DA For oil or process liquids where conduit must be insulated but individual lines are not insulated from one another. Insulation is a diatomaceous earth lining, moulded and keyed to inside of tile. May also be used (Type DF) with fibre insulation for steam heat, power and superheated steam. Applicable to Standard, Super-rTile and Cast Iron. Ric-wiL accessories are available in all type systenis; standard and special fittings, factory fabricated or field fabricated expansion devices, alignment guides, and anchors.

Straight run with pipes one above the other. Perspective of Complete System. DESCRIPTION OF "Z"crete SYSTEM The "Z"crete System is the modern, superior method of insulating underground pipes with "Z"crete Insulating Concrete. The operations involved are as follows: 1. A structural concrete base or pad is placed in the bottom of a properly graded trench to support the pipes. 2. The base is waterproofed on top. 3. Precast "Z"crete blocks are placed on the waterproofed base at intervals and the pipes are placed on them. 4. When the pipes are placed, they are wrapped with paper to provide a cushion for pipe expansion. 5. Reinforcing mesh is placed around the pipes, and forms are set to provide a minimum thickness of 6 inches of "Z"crete around and over the pipes. 6. "Z"crete is poured monolithically around the pipes in a continuous mass between loops or man holes. 7. When the "Z"crete has set, the forms are removed and the exposed sections of concrete are waterproofed. After this, back-filling may begin. DESCRIPTION OF "Z"crete INSULATING CONCRETE "Z"crete Insulating Concrete is formed by mixing "Z"crete Aggregate with Port land cement, "Z"crete Waterproofing Admix and water. "Z^crete Aggregate is made by exploding an unusual mica ore which forms a featherweight, all-mineral, inert, rotproof, fireproof, granular material with high insulating properties. "Z"crete Waterproofing Admix is a specially prepared liquid waterproofing medium which is added to "Z"crete during mixing. ADVANTAGES OF "Z"crete SYSTEM 1. It increases efficiency by creating a con tinuous, unbroken covering of insulation around the pipes. 2. It forms a solid covering of water-repellent insulation eliminating joints or hollow spaces which could fill with water should the water proofing leak. 3. It provides a permanent type insulation not subject to disintegration upon wetting, which is fireproof, chemically inert and rotproof. 4. It minimizes danger of damage to insulation or waterproofing due to handling. 5. It simplifies the installing and insulating of underground pipe lines.` ENGINEERING SERVICE AND SPECIFICATIONS For engineering service and specifications write to the Universal Zonolite Insulation Co., 135 S.
