Meeting Wo. 10 Meeting With Refinery Personnel INSULATION IMPROVEMENT PROGRAM * MEMORANDUM OP BATON ROUPS MEETING MARCH 3, 1955 A meeting was held in the conference room of the Central Mechanical Building in the Baton Rouge Refinery to discuss insulation materials and practices from the Installa tion, materials, and maintenance point of view. It was at tended by: Mr. D. Donald - Asst. Head, Stores Dept., Baton Rouge Refinery Mr. W. W. Evans - Foreman, Masons, Baton Rouge Reffinery Mr. R. J. Oebhart - Buyer, Purch. Dept., Baton Rouge Refinery Mr. D. W. Hanagriff-Gen. Foreman, Masons, Baton Rouge Refinery Mr. F. Houghton - Special Assignment, Mech. Eng. Baton Rouge Refinery Mr. J. E. Langley - Group Head, Equipt. Inspect. Baton Rouge Refinery Mr. H. Lelendecker- Equipt. Inspect. Baton Rouge Refine ery Mr. R. B. Tucker - Div. I Engineer, Baton Rouge Refin ery Mr. P. Wamsley - Asst. Dept. Head, Equipt. Inspection, Baton Rouge Refinery Mr. J. Whitney - Fire Protection, Equipt. Ihspection, Baton Rouge Refinery Mr. W. R. Hnot - Procurement Section, Esso Engineer ing All those present representing Baton Rouge were asked to give their opinions on the subject and they volunteered the following: " ^ ' HOT PIPE INSULATION Combination Insulation -X >v*/" /2*F$ j* hi*. Uf ~ti -oCJ, ~t*--f* ' Calcium Silicates (like Kaylo, Therraobestos) They were indifferent to this ma terial, suggested a super-X and calcium silicate combination be In cluded In the new specs. They pointed out that Unibestos, 8$ Magnesia, Calcium Silicates, Super-X were priced the same in this area. They think the^e materials are equal to each other, and are not too fra gile. 000? Calslllte Haven't used this Sponge Pelt They are trying to get away from this material because of expense. It Is approx. 4l to 5falser than the calcium silicates. Flberglas Has temperature limita, have not used the blanket type. Foamglass Have used It with varying suooess. Is subject to vibration and Tire damage. (It was pointed out that at Baytown the trade unions do not like this material, and If used ask for many special concessions like showers, etc.; as a result the use of this material is being avoided.) Cellular Silicate This material Is similar In some respects to Foamglass. It is an experimental material manufactured by Pittsburgh-Coming and is not yet available for use. Baton Rouge feels that this material has great possibilities and is waiting to try it. ? Unlbestos They like this material. Have not had any difficulties with skin Jrr1 tation. , INSULATION TIES They prefer the use of 14 ga. copper clad wire, Have used galvanized wire. PIPS OUTER COVERINO Plretard This material is used In the re finery. It is expensive. Costs about 21j5/4` in place. Pireguard -- * .j.* /_ fr This Is a cheaper, but lighter, sub stitute. j'CsJUtA.AA'&i METAL COVERINO * 58 ga. Galv. Steel Prefer this to Plretard even though It costs about 5f/o ft. more. It 1 T* nnrx/ -3 . ,v j .. 7 . looks hotter. In cost it runs about 26^/0 ft. applied. The only advantage to metal over Piretard is appearance--especially since paint- ing is the order of the day. Aluminum Childers', etc. Cannot see any advantages except appearance. Do not expect much life from this material since aluminum corrodes rapidly in the Baton Rouge area (a contributing factor is the Ethyl Corporation plant nearby) Seventy (70) miles away, the Shell Refinery recently completed new units with vessels and piping covered with alumi num. It was learned that they have had some difficulties, but mainly because of galvanic action due to dissimilar metals in contact. Baton Rouge is of the firm opinion that aluminum does not-have a place in this area. STEAM TRACED LINES Sponge fult squeezed to shape is, in their opinion, the cheapest and best application. t FITTINGS They prefer prefabricated Unibestos fittings. These are purchased completely weatherproofed. They find that they are more economical in sizes 6 in. and up. The smaller sizes cost a negligible amount more. These fittings are now carried in the refinery storehouse. If, of necessity, the fittings have to be field fabricated they are built up of regular pipe insulation material, mitered, cemented, then weatherproofed with a mastic like Laykold. . They have also purchased prefabricated fittings with out weatherproofing. There is no advantage in this. They will not do this again. Flanges and Valves . Are rarely insulated, except for process or for personnel protection. They are experimenting with remov able sections of insulation for these locations. .. - 0003-A
