Ric-wiL Interlocking Conduit--Ric-wiL Con duit is first quality, standard weight, vitrified salt glazed tile of the bell and spigot type. It is shipped on the job in full round sections and split into top and bottom halves as used. When installed bell and side joints are sealed with Portland cement. - The top half has an overhanging lip that interlocks with the bottom half, providing extra cementing surface and protecting the side joints of tile against water. Top and bottom halves are numbered in pairs so that companion pieces may be kept to gether. Sections all in 2-ft. lengths, sizes from 4 to 24 in. inside diameter. Every sixth section of conduit has an opening in the bottom half through which a pipe support of the roller type projects to carry the steam, hot water or oil pipes thus making the pipe supports independent of the conduit itself--a desirable feature for this class of work. Ric-wiL Interlocking Base ' Drain--Ric-wiL ' Base Drain is first quality vitrified salt glazed tile of such design that it is both a base for supporting ' and lining up the conduit, and drain for carrying away any water which might otherwise accumulate around the conduit. The base drain also provides two points of support for conduit, adding 35 per cent to the ground load which the conduit will carry safely as compared to the same conduit placed on flat ground or broken stone. The top of the base drain has a slot in it into which the bell of conduit fits thus making sections of conduit and base drain stagger with each other so that a strong interlocking construction results. . No concrete foundation is necessary in solid ground. Free drainage area of the base drain is large and ample for every practical condition. Three sizes are made: No. 1 for 4 and 6 in. conduits. No. 2 for 8 to 15 in. inclusive, and No. 3 for larger sizes.- We will furnish ordinary drain tile instead of base drain if desired but the base drain will save more than its extra cost in labor and makes a far better job. Ric-wiL Pipe Supports--The pipe supports are planned to carry from one to five or more pipes and are ordinarily spaced 12 ft. apart. They are strong, made of cast iron, rust proofed, and interlocked with the base drain, imposing no load on the conduit itself. Once in place, no movement of the pipes can disturb them. Ric-wiL Conduit Systems - for All Uses-- Ric-wiL Conduit is of four types to meet varying service requirements. Type SPC System for steam heating and power pipes and for superheated steam. The tile itself is not lined with insulation as in types DA and DP but the insulation is applied to pipes direct and consists of any standard make of sectional pipe covering, the kind and thickness depending upon the service to be rendered. Double drainage is provided in this type. Type F System for steam heating and power pipes. A lower priced type than the others, consisting of unlined Ric-wiL Conduit with filler packed around the pipes. Filler is the same as described in Type DF System. Type DA System for hot water, fuel oil, and con densation returns. Tile and insulation in one, the latter moulded inside the tile and keyed in. Consists of a diatomaceous earth (Sil-O-Cel) mixture, light in weight and of high insulating quality; will not deteriorate. This type insulates the pipes from surrounding ground but not from each other, mak- ing it specially adapted to house oil and steam pipes together for fuel oil transmission. Excep tionally easy to install. Type DF System for steam heating and power pipes. This is type DA with the addition of Ric-wiL-Conduit Filler to be packed around the pipes at approximately 15 lb. per cu. ft. The filler is a good non-conductor which will not corrode the pipes nor shrink. Inquiries--Inquiries should state the size of pipe or pipes to be covered and the services to be carried by them--whether steam, condensation return, hot water or fuel oil. If steam, give pressure.
