Insulation Ruberoid Calsilite Calsilite is a molded insulation that provides the physical characteristics re quired by engineers designing modern high pressure steam equipment. It is a com bination of raw materials, ingeniously con trolled, to form a chemically inert product. It is not only unique in its extremely light weight for such material, but it will stand soaking heat of 1250 degrees Fahrenheit indefinitely without changing its value to any appreciable degree. This permits its use on pipe lines and equipment operating at high temperature without the usual pro tective inner layer of less efficient insula tion. The use of single layer insulation also speeds up its application. Calsilite is highly efficient in heat saving; it has a high modulus of rupture; it resists abrasion excellently. There is little breakage of Calsilite in shipment or when handled on the job. It has low moisture absorption when subject to high humidity atmospheres. Calsilite is furnished in both pipe covering and block form. Pipe Covering is made in sections 36 in. long, canvas covered and in such thicknesses that com binations of layers can provide whatever thickness may be required to cope with the conditions. Blocks are made in standard sizes of 6 in. x 36 in. in thickness up to 4 in. All are packed in cartons suit able for easily handling on the job. Imperial Pipe Covering This is a laminated asbestos paper insulation that has been indented to use 22 laminations of asbestos paper per inch thickness. Its efficiency makes it satisfactory for most medium pressure steam work in industrial plants. Its construction makes it ideal for vibrating conditions. It is recommended for temperatures to 600 F. Being an asbestos felt laminated material it is used on vibrating pipes or where hard service is expected. Will withstand water conditions for underground piping. Excellent as an industrial, oil refinery and synthetic rubber plant insulation. Ruberoid Insulating Cements For the finishing of sheet and block insu lation and the insulating of irregular surfaces, such as valves, unions, flanges, etc., the Ruberoid line of insulating cements is complete. This group of cements not only uses as its base asbestos, but also takes advantage of such excellent natural products as magnesia, mineral wool and Vermiculite. Asbestos Cements--Factory Prepared --Grades AA, A, HF. Asbestos Cements--Mine Run-- Grades 115, 214. Magnesia Cement--85 per cent Mag nesia. High Temperature Cement--Grade H.T. Mineral Wool Cement--High Tem perature. Vermiculite Cement--Grade A-ll. Ruberoid Asbestos Insulating Papers and Millboard Asbestos Paper Made of pure asbestos, fire - resisting.
