Practical steam men have long recognized the superiority of 85% magnesia. Its reliable heat harnessing efficiency has made this type of insulation the world's standard for over 60 years. To the known high efficiency of magnesium car bonate, improvements have been added to make Mundet "Custom-Molded" S5% Magnesia the ideal insulation for all heat ranges up to 550'--600 F. Consider this improved heat insulation on the basis of the only true measurement of value: its capacity to serve at highest insulating efficiency over a long period of years . . . perhaps even for the life of a plant. high temperature insulation For temperature ranges above 600'F.. Mundet will provide a special high-temperarure insulation with improved ad vantages, similar to Mundet "Custom-Molded" 85% Mag nesia. This insulation is designed for use on steam lines, boilers, fittings and other heated surfaces where higher tem peratures are met.

Mundet "Custom-Molded" 85% Magnesia pipe covering and blocks Mundet Cork Corporation process of manufacture The following descriptions and accompanying illustra tions (taken in our plant) cover a few of the more im portant steps in the manufacture of Mundet 85% mag nesia pipe covering and blocks. These manufacturing operations are an integral part of the modern Mundet concept of superior quality insula tion. efficiently produced. 1. Magnesium carbonate (magnesia) and asbestos fibres, from which most of the water has been removed in filtering, moves bv a screw conveyor into large revolv ing mixers (not shown). In the mixers a measured amount of water, which determines the final density of the insulation, is added and the machines rotated to produce a thoroughly homogeneous mixture. This mixture of magnesia and asbestos fibres is weighed mit by an overhead traveling scale into a battery of ex- Ming machines. Reciprocating metal rods, called agitating fingers (shown at top of illustration), vibrate through the mold in order to dislodge any air bubbles and to assure longitudinal alignment of the asbestos fibres. The removal of a section of pipe covering from the mold is shown in top illustration. 2. After being molded, the insulation, either in the form of pipe covering or solid blocks, is placed on racks and transferred to the drying ovens (shown at right). These ovens, fired by fuel oil, maintain a 400F temperature. The lower right-hand illustration shows the sections of pipe covering being placed on a moving conveyor after they emerge from the drying ovens. At the end of the conveyor is a machine which trims die ends of the in sulation sections so that each piece is of standard length with trued ends which insure that the pieces will fit snugly together. efore packing, each pipe covering section is slit in half longitudinally by machine. These sections are then wrapped in a standard canvas jacket and packed in cartons. 4 ] 85% magnesia heat insulation physical characteristics compressive strength .

By slightly varying the wall thickness, every size and thickness will exactly fit over or into another standard size and thickness. This permits a great many unusual assem blies in addition to those shown on the chart. Usually the variations in wall thickness are plus, but the minus cases are more than compensated for by the higher insulating value of Mundet light density type 85% magnesia. notes applying to table 1.

Both k and h vary with the temperature. The values of k should correspond to the mean temperature of the in sulating slab; and the values of h should correspond to the difference between outside (cold surface) temperature and cold ambienr, or (r,, -- t,.). The k values for 85 % magnesia insulation are given on p. 3 and may be plotted as a function of temperature. The h values are given on p. 11, Fig. 1. As a close approximation to mean temperature, the average of hot and cold ambients may be taken. The hot surface temperature is assumed in equations 1 and 2 to be the same as that of the hot ambient. The cold surface tem perature may be found by trial and error as follows: Estimate a value of cold surface temperature, t,,, say 30 degrees F above the cold ambient temperature, t,.. Deter mine t,, -- t,., then enter chart on fig. 1, p. 11, and read off corresponding h value. With this value of h substituted in equation 1 or 2, solve for q. A truer value of to --tc = q/h (equation 3) may now be determined. Now use Fig. 1 again to select a 0ew value of h; introduce into equation I or 2 and redeterine q. The process of trial and error may be repeated several times until the value of q, hence also of h and c,, -- tt., does not change very much in two successive trials. cylindrical surfaces (pipe insulation) The rate of heat flow per lineal pipe foot may be found from equation 4: Q --- 7T (t tc) 1 , 1 In do/di hd0^ 2k (equation 4) where d,, and di are outside and inside diameters of the in sulation, t the temperature of the inner surface (which is so close to the temperature of steam or hot water flowing in side the pipe that this value may be used A k the mean conductivity of the insulation, and h the rare of heat trans fer at the outside surface. Be sure chat consistent units are used and that the natural logarithm of d./d, enters into equation 4. Assume a value of outside surface temperature, say 30 de grees above chat of the cold ambient, t,., and proceed as with flat surfaces. The first approximation of Q having been obtained, calculate t0 -- t,. from equation 5' (t0 -- to) = Q/ -hdo (equations) Read h again from Fig. L (this curve holds for both flac and cylindrical surfaces), and continue with further trials until a constant or nearly constant value of Q is reached in successive trials. If more accuracy is desired, the value of k should be adjusted to that of the exact mean temperature instead of the approximate average of hot and cold ambient temperatures. two-layer cylindrical surfaces In a similar manner to the single layer, rate of heat flow is: Q= " J, 1 n d d hdc 2k, 1 n d,/dj 2k (equation 6) where d,, is the outside diameter of the insulation, d, the diameter between,the two layers, and d, the diameter of the inner layer (OD of the pipe); k, and kL> are conductivities for the outer and inner layer respectively; other quantities are as before. (For more layers simply add terms to rhe denominator like those above involving the conductivity and natural log.) The calculation is a little mote involved than that for the single layer but is basically the same. Both k,, k^ and h are functions of temperature, and more trials may have to be made than with one layer. Assume mean temperatures for each layer of insulation, then from the data available 10 85% magnesia heat insulation of k versus temperature select values for k, and k^. Assume an outside temperature and determine h as for slabs. Then solve for Q in equation 6 and (t,, --t,.) from equation 5. A new value of h may then be determined. In order to determine new values for conductivity, determine the mean temperatures as follows: Call the terms in the denominator of equation 6 Rr, Ri, and R_. respectively, each representing a thermal resistance. The temperature is divided in proportion to these thermal resistances. Hence the temperature at the outside surface is: R, :,c+'r -(t-tci R: + Ri + Rj and the temperature between the layers is: (equation 7) Rf+Ri t| =tc (t-fc) R,+Ri+R2 (equation 8) Having obtained the outside and inside temperatures for each later, the mean temperature is easily found. Solve for Q several times until, as with single layers, the value for successive trials does not change appreciably. effect of windage The values of h shown below are for still air only. The radiation component of h will decrease slightly when windage is present due to decreased surface temperature. But the convection component will increase markedly, de pending upon wind velocity and direction, pipe diameter, and other factors. Hence no simple table of windage in crease factors for heat loss should be made. In general, for moderate winds of up to 25 miles per hour, the heat loss will be between one and four times the loss without wind age. The overall influence on efficiency, however, is usually not more than a few percent. note: The graph below is for an average pipe insulation finish. With different finishes, the radiation component will vary slightly but the convection component remains unaffected. h versus temperature difference between' surface and ambient, h is in btu per sq ft per hr per degree F (Fig. 1) 0 10 20 30 40 50 60 70 80 90 100 eF 120 140 160 180 200 Mursdet Cork Corporation heat insulation contract service Complete installation services are available by trained, experienced specialists, operating from Mundet district offices in key cities throughout the United States.

The INSUL-F1L com ponents and the INSUL-F1L Product are'produced by controlled manufacturing procedures. The initial heat from high pressure hot water or steam distribution systems converts the 1NSUL-FIL to a thermo-plastic, water resistant and highly efficient insulating and corrosion resistant conduit. BULK DENSITY: Approximately 25 lbs. per cu. ft. (loose volume) or approximately 80 cu. ft. per ton. PACKAGING: OVERALL K FACTOR: STRUCTURAL STABILITY: INSUL-FIL is supplied in multi-wall water resistant paper bags containing 2 cu. ft. per bag and weighing approximately 50 lbs. per bag. K values were determined in the Laboratories of the Research and Develop ment Department of The Atlantic Refining Company. For the purpose of determining relative values, four materials were tested under identical condi tions and employing identical procedures in each case. The following results were obtained: OVERALL K VALUE Clay Soil ........................................ 3.120 100% Bitumen............ ............ .74 INSUL-FIL 451 ^Expanded Perlite.............................. .39 *Checks well with K values for this material reported in recent literature. Results of a series of field tests indicated that the structural stability of INSUL-FIL Conduit was superior to a 100% bituminous conduit tested under identical conditions. TEMPERATURE RANGE: General purpose INSUL-FIL is designed for use with pipe temperatures from 200 deg. F. to 400 deg. F. Inasmuch as refinery facilities are available for producing the bituminous component with controlled softening point, INSULFIL can be designed for a wider range of underground steam or high pressure hot water distribution systems to meet special conditions. DESCRIPTION AND INSTRUCTIONS FOR INSTALLING INSUL-FIL CONDUIT SYSTEMS \ 1. DESCRIPTION INSUL-FIL is a composition of a uniform refined heat stable bituminous material and a precoated expanded Perlite aggregate. The INSUL-FIL components and the INSUL-FIL Product are produced by controlled manufacturing procedures. The initial heat from high pressure hot water or steam distribution systems converts the INSUL-FIL to a thermo-plastic, water resistant and highly efficient insulating and corrosion resistant conduit. The process for the manufacture of INSUL-FIL was developed exclusively for INSUL-FIL CO., INC. -- a Division of MIRACLE ADHESIVES CORPORATION, in cooperation with the Research and Development Department of THE ATLANTIC REFINING COMPANY. The management of INSUL-FIL CO., INC. has a record of more than twenty-five years experience in the underground insulation field. 2. METHOD OF INSTALLATION INSUL-FIL shall be installed by pouring the material from the bag directly into the trench. All water shall be removed from the trench before the installation of INSUL-FIL. INSUL-FIL shall be applied to the clean pipe walls after the pipes have been tested and accepted. Recommended minimum thicknesses are as shown below: Nominal Pipe Size Inches 1" to 6" 8" 10"- 12" 16" Recommended INSUL-FIL Thickness 4" 5" 7" 10" The above table'of thicknesses applies to the thickness of the conduit in place. In other words, the thickness of the INSUL-FIL under, above, and on the sides of the pipe. In the case of multiple pipe installations, the prescribed thicknesses are indicated in "Detail B" which follows. Prior to installation of INSUL-FIL, all water shall be removed from the trench and the trench shall be kept free from water until the conduit has been formed. Precautions shall be taken to prevent i soil being mixed with the INSUL-FIL during installation. A suitable tool shall be used to pack the INSUL.-FIL completely around and against the pipe so as to eliminate any possibility of voids occurring under the pipes. The top of the pipe or pipes shall be covered with the specified minimum thickness indicated above. The material shall then be thoroughly tamped with tamper constructed of a 8" x 8" x Va" steel plate provided with a handle. An approximate 10" stroke shall be used when tamping. When INSUL-FIL is installed adjacent to manhole or building wall, the installer shall require that the piping contractor provide packing between the piping and sleeves passing thru the wall as shown in Detail "D" of the accompanying detail drawings. 3. FORMING THE INSUL-FIL CONDUIT The formation of the INSUL-FIL Conduit is accomplished by the introduction of heat in the pipe or pipes. Steam may be available from existing sources or may be made available by the use of Tank Car Type Portable Heaters with sufficient capacity to maintain required temperatures in the pipe during the time required to form the conduit as indicated in Chart No. 1 which follows. Pipes in the system having low operating temperatures such as hot water circulating lines operating at 180F. or condensate lines operating at 100F. shall be subjected to a source of heat, either water or steam, at 22CTF. or higher for sufficient time, as indicated on Chart No. 1, to form the Conduit. Using steam as the medium to form the Conduit, necessitates the use of valves or traps to release the condensate in order to raise the temperature to the required level indicated in Chart No. 1. In those instances where installations are made in dry soil, trench may be backfilled prior to the application of heat to form the conduit. However, provision should be made for inspection at a convenient point as a check on proper formation of the conduit after heat has been applied for the required time. Time required to form conduit as indicated in Chart No. 1, shall start from time temperature of the pipe has risen to the point indicated on the Chart, and curing shall be continuous for the time and temperature indicated. In the event standing water is present in the trench due to a high water table or-other reasons, the water shall be pumped from the trench by any approved method and pumping shall continue until conduit is formed and backfilling has been completed. If heavy snows or rain are encountered during installation of the INSUL-FIL, heat should be applied and the conduit formed prior to backfilling. 4. PROVISIONS FOR EXPANSION LOOPS OR OFFSETS In addition to the specified thickness, where pipe expansion is provided for by expansion loops or offsets, five inches of INSUL.-FIL in addition to the specified thickness shall be installed on the side of each loop or offset in the direction of expansion. Where a loop or offset is subjected to heavy surface or traffic 4 DESCRIPTION AND INSTRUCTIONS FOR INSTALLING 1NSUL-FIL CONDUIT SYSTEMS loads, an extra five inches ot' 1NSUL.-FIL shall be added to the specified thickness on top of each pipe. Expansion movement on each loop leg or offset shall be limited to a maximum of three inches. Expansion movement of pipes entering bellows or slip-type joints shall be limited to a maximum of four inches. 5. PROVISIONS FOR HEAVY SURFACE OR TRAFFIC LOADS Where the pipes pass under areas such as streets, roads or railroads supporting heavy loads, an extra three inches of 1NSUL-FIL shall be added over the top of the specified thickness, except in those instances where other reinforcing means are required to support the loads. 6. BACKFILL -- GENERAL Following the tamping of the INSUL-FIL as per Par. 2 the material shall be covered by the 1NSUL-FIL bags. A minimum of twelve inches of backfill shall be placed over the bag-covered INSUL-FIL. Manual or machine backfilling methods may be used. Selecting backfill is not necessary. If the backfill is to be consolidated by puddling, the material shall be first conditioned by application of heat as per Par. 3. 7. BACKFILL UNDER PAVED ROADS Where the INSUL-FIL conduit passes under paved roads the structure may be formed either before or after backfilling. After the structure is formed the well tamped backfill shall be brought to grade before pavement is laid. 8. PIPE CONNECTIONS Threaded connections on pipe shall not be used in an INSUL-FIL Conduit System without specific approval of the Engineering Department of the INSUL-FIL CO., INC. All connections on copper piping when used in an INSUL-FIL Conduit System shall be formed by using a high temperature solder or brazing alloy. 9. PIPE SUPPORTS Pipe supports of the types indicated in Detail "G", shall be provided and spaced not more than 10 feet apart. For spongy or corrosive soil, the type of supports indicated in Detail "H" shall be provided. Alternate pipe supports for dry, firm, non-corrosive soil such as shown in Detail "I" may be used. 10. PIPE GUIDES Pipe guides as shown in Detail "E" will permit free movement of the pipe and shall be placed close to the ends of straight runs of pipe, close to the point where pipes enter loops or offsets: guides shall be placed just outside of building or manhole walls where pipes enter an expansion joint. Guides of this type shall also be placed in the center of straight runs, midway between the anchor and expansion facility. Alternate types of guides shall be submitted to the INSUL-FIL CO., INC., for approval. 11. ANCHORS Details "E".and "F" are the type anchors recommended by the INSUL-FIL CO., INC. The appropriate type shall be spaced so that the expansion on each offset or loop leg shall not exceed three inches. In the case of expansion joints, these anchors shall be so spaced that the maximum movement of each pipe entering the joint shall not exceed four inches. Alternate types of anchors should be submitted to the 1NSUL-FIL-CO.. INC., for approval. 12. USE OF FORMS Where trenches are wider than is necessary to contain the INSUL-FIL conduit, material can be conserved by the use of forms. These forms may be made of 14 gauge metal approximately 18 inches wide by 96 inches long with a metal handle affixed at each end, for case of handling. Plywood or other suitable materials may be used in lieu of metal. The forms are placed in position in the trench so as to provide the required thickness of finished conduit. Suitable separators or clamps may be used to hold the forms the proper distance apart. Sufficient backfill may then be placed and lightly tamped behind the forms to furnish support. INSUL-FIL may then be placed inside the forms, properly tamped, as called for in instructions and the backfill firmed by any suitable means outside of the form. The forms may then be easily pulled forward by the handles into the next position and the process repeated. 13. REPAIRS TO PIPING IN INSUL-FIL CONDUIT SYSTEM Repairs to piping in an INSUL-FIL Conduit System in the event of a leak anywhere in the system are easily and readily effected. In the first place the steam will make its way thru the conduit at the exact point where the leak occurs. The usual expensive cost of excavating to find the location of the leak is eliminated. The conduit is readily removed in the vicinity of the leak. The leaky pipe is cut out --a new section welded in place. INSUL-FIL is dumped in place: the steam turned on and the line is back in service with a minimum of cost and delay. 14.
