*** n. To Subject: PITTi. -.URGH CORNING CORF RATION INTER-OFFICE CORRESPONDENCE Roy E. Fuhs From Harry E. Porter Date _June 1.6, 1971 Dear Roy: June 15, 1971, two cartons of 6 x 2 UNIBEST were delivered to Mr. Carter Lee for test application and evaluation. Those present at the test were-; Carter Lee, Humble Oil Company R. L. Anderson, Anco Insulations, Inc. A. T. Fussell, Humble Oil Company A. L. LeBlanc, Humble Oil Company W. T. Matheney, Humble Oil Company C. A. Ashford, Humble Oil Company H. . Graham, Pittsburgh Corning Corporation H. E. Porter, Pittsburgh Corning Corporation The product was very carefully examined by the insulators for hardness, resistance to de1 amination, and dimensional control. We were all pleasantly surprised when two half sections of the covering could be interchanged and reversed and still fit extremely well. In the two cartons examined there was evidence that some of the covering had been stood on an end prior to its achieving dry strength which resulted in slight deformation of one end but the deformation would, in the opinion of the Humble employees, be enough to make the application of their finish material difficult. 1 f/ I The covering was cut for a tee by Mr. A. L. LeBlanc using the normal insulators key hole saw and everyone was most impressed by the ease of cutting and lack of dust. Some mitered cuts were then made by the use of a standard - 2- hand saw with the same results except that the throat end of the miters were fragile (not any more than Calcium Silicate) and comments were that this could be an area for improvement. Sonny Anderson commented that the "ends and edges-couId stand a little stiffening." When the covering was applied to a pipe and secured by wires everyone made favorable comments regarding the imbedding of the wire as compared to UNIBESTOS. The factory must have added some plasticizer to their coating because there was more elasticity to the coating on these particular samples than any I've seen. Mr. Lee had only the following questions: is the costing waterproof? Answer * |n so far as a PVA Emulsion can be considered waterproof. Relative to UNIBESTOS can the material be removed from a carton and applied to a pipe if the carton is left out in the rain? Answer * We have not, to my knowledge, tried this but we will. When will the material be available in quantities large enough to do a job? Answer - | don't know but you will be informed shortly regarding the build up of factory inventory. Will the material be priced competitively? Answer - As competitive as UNIBESTOS is currently priced. JJf'tan we expect packaging such that temporary outside storage is - TM possible? Answer - We are currently evaluating a "shrink pack" system with FOAMGLAS and if it is successful I see no reason why it couldn't be adapted to this product. There is also consideration being given to putting the cartons in plastic bags similar to bread wrappers. Mr. Lee then suggested that we furnish their plant hygenist, Mr. Fred Venable, with a confidential chemical analysis regarding health hazards from dust, etc. I promised to secure such an analysis or whatever management would furnish and contact him. He will then set up a meeting for us immediately. This seemed to be very important to him. After a brief discussion with the mechanics, Mr. Lee then gave Mr. Anderson of Anco the go ahead to furnish UNIBEST on any job he has in this plant. We were very timely with this demonstration since they had just informed Hollinghurst Industries to pick up some sub-standard Kaylo which had been furnished on the current maintenance contract. Small cavities were quite prevalent in the material and about 90/o of it was broken. It was interesting to note also that the cartons had apparently been stenciled in the factory "Humble Maintenance Contract" indicating a very special price for this order. ' Since Humble has had some excellent -expericnees with-mineral wool In various forms (Eagle Pitcher and kb Insulation Company Block, J-M's Zerolite, etc.) it would be my recommendation to give some priority to tests which would indicate the performance to be expected from UNIBEST when subjected to hydrocarbon fires. Hr. Anderson indicated that he would like to use UNI BEST on the Arthur G. McKee project which will insulate during the fourth quarter 1971 and the first quarter 1972. The estimated value of this contract is $500,000.00 labor and materials. Under separate cover you are being sent a sample of UNIBEST which was applied to a furnace line at approximately 1J00F for ten days. The sample adhered itself to the pipe and was slightly difficult to remove. The sample appears to have a white substance on the bore and there has seen some discoloration of about l/`!" of the inner material. I would appreciate your comments when this has ceen examined. Needless to say we ere very pleased with the results of this demonstration end look forward to getting the "go ahead" for more in the form of production cepabi1ity reports.
