Tile and cast-iron in 24 in. sections, sizes 4 to 27 in. inside diameter. A Super-Strength tile conduit which laboratory tests by A.S.T.M. 3 point method show an average crushing strength of approximately 3000 x per foot diameter per lineal foot. A light weight cast-iron conduit specially designed for bad water conditions and a heavy cast-iron conduit for extra heavy duty. Base Drain---Standard Base Drain is vitrified salt glazed tile for tile conduit and extra heavy tile or cast-iron for the cast- iron conduit, in 24 in. lengths. Special IJ-Type Base Drain to hold return line and Support Blocks for use with round tile construction also available. Pipe Supports--Standard Pipe Sup ports for tile conduit are of the externally supported type with rollers for single or multiple pipes. Load is carried entirely on side shoulders of Base Drain. Pipe Supports for cast-iron conduit are of the internal type and are cast integral with the conduit. Pedestal Pipe Supports also available. Details of Ric-wiL Alignment Guides and Anchors furnished upon request. insulation -- Dry-paC Waterproofed Asbestos Insulation, non-settling and non- corrosive--packed into the conduit be comes a solid matted mass without cracks, joints or openings--positively non-capil lary and water-repellant. Has low con ductivity and insures highest thermal efficiency--non-waterproof kind also fur nished. Lined conduit insulation is a Ric-wiL Cast Iron conduit has ample strength with minimum weight for use under roadways, railroad true**, or other places subject to ex- * trrne loads and vibration. It it installed without delays and with out added con struction or engi neering. Cutaway view at pipe support showing how Ric-wiL parts interlock. Note Loc-liP Side Joints and how pipe assembly it independent of the conduit. Cut shows Type DF System, lined conduit, with Dry-paC Waterproofed Insulation. moulded diatomaceous earth mixture. Sectional pipe covering, sponge felt, 85% magnesia, etc., can also be furnished. Accessories--Conduit fittings, with Loc-liP Side Joints for all types up to 15 in. are carried in stock--45 deg. and 90 deg. elbows, tee branches and reducers. Tee branches and reducers made to order for larger sizes. Mitred Base Drain fittings made for all conduit fittings. Shutter sleeves of galvanized iron, with asbestos rope for encircling pipes to provide a form upon which to cement or brick in ends of conduit lines.

Boston, Mass. PRODUCTS--Engineering and Contracting of Steam Line Installations. Underground Steam Conduits. USCCO PRE-CAST CONCRETE CONDUIT This unit marks a long step forward in the economics and mechanics of laying under ground steam lines. Its Outstanding Features Are: Strength resulting from flat reinforced bell; from the longitudinal joints, and from the fact its sections are 4 feet long, reducing the usual number of joints necessary. Shape which allows 12 per cent greater inside capacity than circular conduit of like diameter. This permits larger pipes in a given size conduit and more room for drainage, pipe supports and rolls. 0 StCTIO* MATCMAL Ease of Installation resulting from the fact that all top and bottom halves mate. Bottoms may be laid for any distance, the piping installed and then the tops brought up and laid. This speeds up the work and protects idle halves from damage. They can be stored away from the job. Materials are high strength cement with suitable aggregate, amply reinforced with wire mesh. ..(.-- BOTTOM SCCTON Pipe Supports arefof cast-iron and quickly installed. .They may be placed anywhere in the conduit. The weight of the pipe holds them in place. Joints may be of any standard accepted brand of jointing compound or they may .... be of standard Portland cement mortar.. 863
