CEDEDOE} INSULATION .HIGH TEMPERATURE HIGH TEMPERATURE INSULATION HIGH TEMPERATURE INSULATION The high temperatures existing on heating and process equipment in power fiou?es. renncrie-j, chemical plants, etc-, have made it important to provide a durable material that will withstand these hi:hvr temperatures. "FI. T." insulation can be used up to 1900* F. without disintegrating. Ft is recommend? i as an inner layer for use ia combination with other more efficient. low density Insulation to rc Ju-v the temperature to within the range of such materials.

It is- a calcium silicate compound uiing selected raw materials that, when combined and ingeniously controlled, form a product free from harmful ingre dients. It is not only unique in its extremely light weight for such material, but it will stand soak ing heat of 1250* F. indefinitely without changing iU value to any appreciable degree. This permits ' its use on pipe lines and equipment in either single layer of required thickness, or two or more layers should be specified. The use of single layer insulation also speeds up its application. CaJ.'ilite is highly efficient in heat saving; it has a high modulus of rupture; it resists abrasion excel lently. There is little breakage of Calsilite in shipment or when Handled on the job. It has lowmoisture 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 combinations of layers can provide whatever thick ness may be required to cope with the conditions. Blocks are made in standard sizes of 6 in. x 36 in. in thickness up to 3 in. Packed in cartons and crates suitable for easy handling on the job.

Low density and high efficiency combined with structural strength make it popular for all industrial and power house work. Ideal for marine insulation. A variety of thicknesses are provided to give the maximum efficiency for each temperature. Flat and curved blocks are available for boiler surfaces, breaebings. tanks, etc. 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 500 F. Being an asbestos felt laminated material, it is used on vibrating pipes or where hard service is expected. Suitable for underground piping. Excellent as an industrial, oil re finery and synthetic rubber plant insulation. ASBESTOS SPONGE FELT Sponge Felt Pipe Insulation is for temperatures up to 700T. Composed of asbestos felt paper with a maximum amount of spongy content evenly distributed. There are 37 to 42 laminations to the inch. This produces a uniformly round and rigid insulation of extreme density. Over the outside is a heavycanvas jacket. Because of its rigidity and ability to withstand damage from abuse, particularly adapted for use on vibrating lines and on pipe lines where insulation must he removed at frequent intervals. <------PRODUCT TtMPtRATURt INSULATION OUIDI 4
