J-M THERMOBESTOS | DESCRIPTION: A molded, high tempera ture pipe and block insulation, J-M Thermobestos is composed of hydrous calcium silicate bonded th with asbestos fibers. It is a completely inorganic 'insulating material which, because of its light weight, Similar in chemistry and composition to a \er\ low thermal conductivity, great structural strength and insolubility in water, is ideal for high tempera concrete, Thermobestos will withstand unusual , ating abuse without appreciable damage. [ ture piping and equipment. | AVAILABLE FORMS: Thermobestos is furnished in both sectional pipe insulation and block form. The pipe insulation comes in a com Extrema Lightness Thermobestos is as light as many insulating ir..:r possessing a fraction of us strength and durabi.it-. I plete selection of sizes up to 24" x 3" half-sections. Larger sizes are available in quad segments from Chemically Stable 25" to 33" P/S in 1 Vi. 2, 2Vi and 3" thicknesses. Bevelled and scored blocks are available for larger 1009r inorganic, will neither burn nor rot. diameters. Regular blocks furnished in 6", 9", 12" x 18" widths by 36" length, in a full range of Not Damaged by Water thicknesses. | USES: Especially recommended for use in Can be soaked in water without damage. After dconductivity will be as good as new. the power generation and process industries on in door and outdoor piping and equipment operating at temperatures to 1200F. Thermobestos is light enough for easy handling and fast application. Re peated wettings have no permanent effect on it Easy Application Thermobestos is purposely made in large block' half-sections to facilitate handling and reduce ber of joints. which makes it ideal for installations subjected to weather, or for insulating underground steam lines. Low Conductivity Because it will not bum or cany flame, it may also be advantageously specified for use in the presence of inflammable gases and liquids. Thermobestos offers the lowest k factor of all i tions m general use throughout the power gencr.i: and process industries. THERMOBESTOS Specification Data Cl Cl Cl a ci ci ci ci ci The h|u'es into m this uo>t are iH'lll *siues detained m accordance with acctpteo test methods. _ COMPLIANCEWI^^*^^':;4^r.^^i^^,L^COMPLIANCE WITH GOVERNMENT SPECS,/ ** 7 '*< ASTM STANDARDS Pipe Insulation: MIL-l-2781 C Grade I. class b. to SOOF Grace II. class t). to 750F Grade III. class e. type I and II. to 1050F FEDERAL HH-l-523 A Class 2. to 1200F Black Insulation: MIL-1002819 B Class 1. to SOOF Class 2. to 1000F FEDERAL HH-l-523 A Class 1. to 1200F Pipe Insulation: C345-54T. to 1200F Black Insulation: C344-54T. to 1200F An Insulation for Every Commercial and Industrial Purpose Block Insulation - ,7T : RECOMMENDED THICKNESSES) ~ lnnirtn f ttrfaca.

The Johns-Manville manufacturing process provides the material with a maximum number of voids, or minute dead-air cells, which increases the natural resistance to heat transmission and reduces the weight of this dur able insulation. Maximum mechanical strength consistent with high insulating value is an added advantage. ADVANTAGES Good Compressive Strength J-M 85 % Magnesia has the compressive strength nec essary to withstand all normal abuse to which exposed piping and equipment may be subjected. Chemically Stable 100% inorganic, will neither burn nor rot. | AVAILABLE FORMS: J-M 85% Magne sia is furnished in both sectional pipe insulation and block form. The pipe insulation comes in a complete selection of sizes up to 14" x 2" half sections. Larger sizes are available in segments and curved blocks. Blocks are available in widths of 3. 6. 9 and 12", and lengths of 18 and 36". in a full range of thicknesses. 6" wide curved blocks are available for larger diameters. | USES: Recommended for use to 600F on heated piping and equipment in schools, hotels, hospitals, public buildings, ships and industrial in stallations of all types. For temperatures above 600F. J-M 85% Magnesia is often used as an outer layer over J-M Superex. This construction--known as Superex Combination--combines the high heat resistance of Superex with the greater insulating value of 85% Magnesia. Low Maintenance For practical purposes J-M 85% Magnesia is ageless and will last as long as the masonry in a building Withstands Wetting Will withstand repeated wetung and drying without deterioration. High Insulating Value Has a thermal conductivity of .46 at 400F mean tem perature. Light Weight Easy to handle and install. JOi An Insulation for Every Commercial and Industrial Purpose J-M SUPEREX block insulation 10 | DESCRIPTION: J-M Superex block insula* lation is composed of calcined diatomaceous silica blended with other insulating materials and bonded with asbestos fiber. These light weight, large size blocks will withstand temperatures up to 1900F with negligible shrinkage. Their unique combina tion of low conductivity and high stability at ele vated temperatures provide excellent efficiency and long, maintenance-free service. Ever since its introduction, Superex has demon strated its versatility as a high temperature insula tion. Today, for example, it economically insulates 90% of this country's hot blast stoves. AVAILABLE FORMS:Furnished in flat or curved blocks in the following sizes: Flat or curved, 3" or 6" wide by 18" or 36" long. Flat only, 9" or 12" wide by 18" or 36" long.

These four refractories are especially adaptable for gun application in building new refractory linings -and repairing old ones. They adhere readily with a minimum of loss when "shot" in place. Mixed with water at the gun nozzle, they are pneumatically projected with great force, resulting in a dense, homogeneous lining. Blazecrete is equally effective for heavy patching by troweling, especially where brickwork has eroded deeply. It eliminates the laborious ramming or tamping required with "plastics," and patches need not be prefired. 56 AVAILABLE TYPES: 3X Blazecrete--For service to 3000F.

The use o! refractory mor tars reduces slag or gas penetration and cuts down heat loss caused- by open joints. There are two gen eral classifications of bonding mortars: heat setting and air setting. Heat setting mortars will develop a bond only with the application of heat. Air set ting mortars develop a strong bond without the application of heat. J-M Bonding Mortars have been scientifically formulated to insure good workability, low shrink age, and long shelf life.
