UNIBESTOS*.. . the only industrial insulation made in the United States composed of unique long-fibered Amosite asbestos... is now manufactured by Pittsburgh Corning. Rugged and durable, UNIBESTOS has proved itself an ideol high temperature insulation in the marine, refining, chemical, power, and petrochemical fields. EXCLUSIVE COMPOSITION... offers unique natural advantages UNIBESTOS is a sectional pipeinsulation material made up of approximately 95% long-fibered Amosite aabestoe, combined with an inert silicate binder and diatomacecus earth. Amosite asbestos offers a host of unique natural insulation ad vantages which stem from: (11 Unusually long. fine, tough fibers. 2 - Inert chemical make-up. 13 ' High degree of resistance to moisture. V. The Amosite asbestos is processed by a special Pittsburgh Coming production technique called fiberi*ing, designed to exploit the full natural advantages of the long- fibered material. In this process, the Amosite is carefully screened, air blown, and brushed to "open up" the long, fine asbestos fibers into an interlaced fibrous mass which entraps millions of insulat ing air spaces. UNIBESTOS is produced by carefully forming this exclusive base material into sections of precise thicknesses, then applying a smooth, chetnically-inert refractory coating. The photographs on the oppo site pege graphically illustrate why UNIBESTOS is unique among insulations in its make-up and manufacture: the pages fol lowing will demonstrate that. . - for economy, efficiency, tong tervUt and re-usability L'M1BESTOS is your best buy in high temperature pipe insu lation. The photograph below- fives a vivid demonstration of the nat ural difference between longfibered Amosite asbestos and or dinary asbestos. These long, thin fibers have an amaring degree of resilience. Not only does each fiber offer a high resistance to forces that tend to bend it. but groups of fibers... properly proc essed and "opened " . . . form an interlaced fibrous mass with un usual structural strength, as well as high insulating efficiency. Amosite asbestos ia found chiefly in the north central Trans vaal. a province in the Union of South Africa, where uniform, graded Amosite is produced by modern facilities of the Cape As bestos Company for export to Pittsburgh Coming plants. - TNt picture plows ttie difference between equal weights of long-fibered amosite asbestos end on ordinary asbestos materiel. The pile of amosite on die right, "opened" to oitnost three times the volume by me PC fiberirinj process, will retain its original Huffy mass indefinitely. Ordinary asbcitat. with its short, more brittle fibers, lendi to pack dawn. J r APPLICATION pqBfnKSTi^ SINGLE-LAYER INSULATION... saves time, lowers application costs Because of iu unique combina tion of properties. UNIBESTOS offers many advantages in both thermal efficiency and reduced in stallation coats. UNIBESTOS has high insu lation value. UNIBESTOS ia composed of Amosite, a superior grade of asbestos. One pound of Amosite will bulk to two or three times the volume of common short asbestos fibers, such as white Chrysotile or blue asbestos. The PC fiberizing process pro duces a mam of dead-air cell* that result in low thermal conductiv ity. This positive thermal effi ciency eliminates "guesswork" in specifying excessive safety fac tors. reduces over-all application ' costa. UNIBESTOS needs no addi tional layers. With UNIBES TOS. butted joints form natural heat seals themselves. The long, tough fibers . . . which project from the butt end of sections by the thousands . . . lend to inter lace when two sections are butted together. This forms a heat-tight joint and eliminates the need for additional layers required with other insulation materials. Teats show that for equal thicknesses, a single layer of UNIBESTOS loses considerably less heat at the joint than the outside joint of a double thickness of other kinds of insulation.

UNI BESTOS can be cut. mitered, or grooved wirh ordinary tools. It can be neatly adapted to bends, elbows, tees, expansion joints, flanges, valves, and other irregu lar shapes. Here, too, the joints form heat seals through the inter lacing effect of the long fibers. And. since UNIBESTOS will not shrink at high temperatures, joints stay tight and efficient. This inherent heat sealing elimi nates the need for special insulat ing treatment ofjoints and seams. Shop fabrication is simple . . . just cut UNIBESTOS to size and join with sodium silicate adhesive. UNIBESTOS is easy to han dle, speeds installation. UNI BESTOS is a Arm, easy-to-handle material not subject to breakage. This lowers installation, shipping, and materials handling cost. Sin gle-layer UNIBESTOS can be installed in much less time than required for double-layer insula tion. Fewer number of insulation pieces requires less space in stor age and shipment. Fewer pieces must be handled in all operations, reducing labor time end costa ail along the line. Practically no loss through breakage. UNIBESTOS nerd not he handled delicately! It is so rugged it will not crack or shatter on impact, even when struck with a hammer. In addition to per mitting faster work, shock resist ance saves money because break age replacement costs arc practi cally nil. It does not break in transit, thus excess quantities need not be ordered to compen sate for in-transit breakage. Independent laboratory tests prove superiority of sinflt-ieyer UNIBESTOS insulation system. The chart illustrate* results arrived at by an independent test ing laboratory when testing for hest losses at insulation joints. Single-layer UNIBESTOS was tested against double-layer appli cation! of competitive materials. _ DURABILITY pcu::;sS70s RUGGED UNIBESTOS... incombustible, won't shrink, no thermal shock UNIBESTOS protects piping against costly damage from fire. UNIBESTOS is incombusti ble because it is a stable, inor ganic iron silicate, and cannot bum. Further, its high insulation value snd ability to withstand violently sudden temperature changes protect piping against ex cessive and rapid heat gain. Where non-insulated or poorly in sulated piping buckles and melts in industrial fires. UNIBESTOSinsulated piping stays in place and is ready to function when the fire is brought under control. (See arrow in photograph of actual plant ore.) No thermal shock problem Even at temperatures higher the the 1200*F service tempera ;urecommended for UNIBESTO; it will not thermal shock . . . r cracks or leaks will occur to ir. pair insulation efficiency. UNIBESTOS has exceptional stability--won't shrink. Be cause UNIBESTOS is extremely heat stable ... it does not decom pose or react chemically under high temperatures. Even more im portant. it is dimensionally stable . . . it does not shrink! With UNIBESTOS that, section joints stay doeed. and keep heat in. UNIBESTOS resists water, moisture, scids, fumes. UNI BESTOS is chemically stable: it is not affected by water, mois ture. scids, fumes, or other corro sive substances. Submerged un der water for weeks. UNTBESTOS dries to its ariginsl charac teristics: continuous exposure to chemicals and chemical fumes does not change its insulating e- pacity. UNIBESTOS for stainless steel applications. Many indus trial users of UNIBESTOS have expressed satisfaction with the insulation performance of UNI BESTOS on stainless steel appli cations. UNIBESTOS can be re-used. Because of its durability. UNI BESTOS can be re-used many times. Maintenance costs are re duced because new replacement insulation is not required when s line is repaired. As is shown in the illustration at right, even Aange. valve and coupling coverings can be easily fabricated right on the job for later removal, when nec essary. VERSATILITY^ VERSATILE UNIBESTOS... high thermal efficiency ir every application UNIBESTOS haa proved itself in use in the widest range of indus trial. commercial, and govern ment installations to be the most versatile high-temperature insu lation available. Its high thermal efficiency means plus-profits in the form of major, long-term operational economies. Its inert composition, and re sistance to moisture, acida and chemical fumes assure long life is the most contaminated industrial surroundings. Its resistance t shock and abuse, end its ease of removal and reeppliestion not only simplifies maintenance, but cuts mainte nance expenses sharply. Its compact, trim, single-layer* application offer* the ultimate in labor-saving, without samncs of insulation value. UNIBESTOS ie proven best for petroleum refineries and petrochemical plants. UNI BESTOS offers superior insula tion performance in corrosive at mospheres, end protects against pipe destruction in sudden and violent fires. Of particular impor tance is its application to heattraced lines where its ability to conform to irregular shapes elimi nate any cracking or breakage of the material. UNIBESTOS will alas bridge the unsupported void between the line and tracer with out breakage. UNIBESTOS is proven best for the utility industries. For power planu with high tempera ture steam lines, for commercial steam heat systems, for exposed critical-temperature lines of all types. UNIBESTOS excels in In sulation performance. Tough and resilient, it won't crack or ther mal shock. keeping thermal effi ciency high and reducing heat losses over longer piping runs. UNIBESTOS is proven best . i for pulp and paper mills. In the wet. corrosive atmospheres of pulp mills and paper mills. UNIBESTOS performs at peak effi ciency. Continuous exposure to chemical-laden fumes does not affect it; even after being totally submerged in water for weeks, it will quickly dry to its original characteristics. UNIBESTOS is proven best for marine use and atomicenergy applications. The sin gle-foyer concept of the UNIBES TOS insulation system makes it ideal for the demanding condi tions of cramped shipboard pip ing. particularly on atomic-pow. ered vessels. Its fibrous structure withstands the rigors of heavy vibration which could cause gran ular insulations to break and crumble. The combination of unique advantages in UNIBES TOS are proving equally effective in the atomic energy field. UNIBESTOS saves on under ground lines. Because UNI BESTOS is available in full cyl indrical shapes up to 44' insula tion O.D.. it has gained wide spread acceptance as the time saving way to insulate under ground lines. Requiring less han dling and no special banding, these full cylinders provide an ideal way to insulate a line for conduit application. Installation is simple: the insu lation is slid onto the pipe; the transverse joints are taped and insulated pipe is ready for the casing. The casing is then sealed to make a strong, efficient and economical assembly for the dis tribution of steam or fluids under ground. This system has become in creasingly popular where heat is supplied from a central heating station. In situations like these. UNIBESTOS has supplied supe rior underground insulation for everything from schools, churches and colleges to hospitals, utilities and railroads as well as for proc essing lines for industrial plants. WIDEST SELECTIVITY. . half sections or full-round sections up to 44" insulation O.D.

UNIBESTOS pipe insu lation is manufactured In thick nesses that conform to accepted industrial and manufacturer's standards known as simplified dimensional uandaris. In order to conform to these standards, the outside diameters of all UNJ- PERSONNEL*PROTECTION BESTOS sections closely approxi mate those of iron pipes. By conforming to these stand ards the installation of UNIBES TOS is further simplified and any dimensional confusion or adjust ment is eliminated. These uni form manufacturing standards are particularly useful in the fab rication of valve tnd fitting cov ers. etc., where nesting layers of UNIBESTOS sre required.
