Braun Date: July, 5, 1988 Subject: Corporate Technical Council Meeting MEMO As a result of our Corporate Technical Council Meeting, I am taking the liberty to present an area of interest to us to the attendees I believe may have comparable interest. I've attached some of the results of our investigation, and if you have any information which might help us in our material application search, I would like to receive it. It was, for me, a worthwhile experience, and getting to know people in our other Divisions is very helpful. Henry w.

NJ ub.ils 609-499-JUWJ NON ASBESTOS GASKET USE Information exchange desired. Condenser Oivision, in accordance with invoked Military Specification and prior general practice, had used compressed asbestos sheet gaskets generally 1/32", 1/16" or 1/8" thick. Although asbestos, gasket material completely contains the asbestos fibers, the increasing awareness of customers and the general population of a possible health hazard led us to eliminate the use of asbestos gasket material on commercial applications. On these applications we generated the attached Engineering Memo #55. We have also generated a number of requests to the Navy requesting them to generate an alternate material specification to the HH-P-46E Specification which was invoked in our product specifications. We have been made aware that the Navy has issued Mfl-G-24696, and several suppliers are attempting to have products qualified. Our correspondence with them is attached for your reference. k Condenser Engineering Manager HW8/ms TX0358 ENGINEERING MEMO E-55 October 1, 1985 GASKET MATERIALS AND DRAWINGS Compressed asbestos gasket material is difficult to obtain commercially (and is becoming more so) since just about all sources (at lest in the U.S.A.jhave curtailed or discontinued its manufacture. Several excellent substitutes for the sheet asbestos gasket material have been developed and are available commercially. Some of the acceptable substitutes meeting ASTM F-1C4 are: 1. Garlock - Blue-Gard 2. Anchor Packing - Style 443A 3. Richard Klinger Inc. - Klingersil C-4400 These materials are rated for 750 degrees F and pressures to 1450 psi. They are to be used for all applications falling within this operating range for which asbestos fiber sheet has been previously used; principally for the tube sheet-shell gasket. They are. effective immediately, our standard gasket material for this service. Customer's specifications requiring asbestos gaskets are to be questioned (by project engineer), making specific efforts to substitute these materials (where possible). Drawings for gaskets made in "more than one piece" are to show location and type of splices; they (the gasket drawings) will contain cutting sketches showing the "nesting" of the various gasket pieces on the sheet gasket material. The available sizes of gasket material is to be determined at the time the gasket drawings are prepared; the sizes and quantities needed for the job are to be order via bill of material (as opposed to use of stocked material as is the present practice). Project Engineers are responsible.for the implementation of these instructions. TX0359 Engineering Supervisor MJl:bf c.c.: Drafting Department Engineering Department J. E. Bricker R. G.

BLUE-GARD gukcu are available in thicknesses of 1/32" thm 1/8". BLUE-i-ARD non-asbestos material is made by the tradition al shatter method that has proven itself since 1S96. BLUF.-GARD gaskets meet most of the properties of A STM ~ 104 for compressed asbestos material. BLUE-GARD gaskets eliminate the problem of meeting OSHA and EPA asbestos standards. BLUE-GARD gaskets are comparably priced with asbestou when you figure in the costs of compliance with current regulations. With tests indicatingGARLOCK BLUE-GARD gaskets serve reliably in mostapplications.youcan expect theexceptional level of performance for which the G ARLOC K name has always been k nown.

TX0361 GARLOCK BLUE-GARD gaskets are cut from tough gasketing material manufactured and formulated without asbestos. They're easier to handle on the production line, add a new element of product reliability, and provide designers and equipment manufacturers additional sales potential. Their fiber content is acrylic, bound by nitrile. More than two years in development BLUE-GARD material now stands alone as a proven replacement for standard compressed sheet gaskets. BLUE-GARD gaskets can be safely installed in most static sealing applications. They have wide areas of use in manufacturing and processing, off-highway transportation, compressors, small engine applications, and many ocher products. BLUE-GARD gaskets are excellent for severe service involving higher pressures and temperatures. They are especially useful where heavy flanges and high bolt loads are commonly found, such as in steam lines, engine cylinder heads, compressors, and refrigeration equipment BLUE-GARD gasket characteristics have Iwen successfully tested to fluid resistance in pH range 1-11. and temperature resistance to *.'<71T See reverse side for specification*. k Compressed Non-Asbestos Gasket Sheet KLINGERSIL C-4400 High quality NON-ASBESTOS material composed of fibres with highest chemical stabili ty and heat resistance.

April 17, 1985 00 Form 1426 MIL-C-15430J & MIL-E-15465G Sheet 2 l.B. RECOMMENDATIONS FOR CORRECTING THE DEFICIENCIES Above paragraphs of subject specifications contain asbestos material. Because of the defined health hazards associated with asbestos we are receiving letters from manufacturers of the sheet gasket and spiral wound gasket stating that shortly they will be discontinuing the use of asbestos as a gasket material. If the Navy has adopted any alternate non asbestos gasket material and has generated the associated specifications we would like to have them identified. We also believe, an amendment or revised specification should be issued to provide authority to use an alternate material for application in the identified paragraphs; i.e.: (1) MIL-A-17472 - Replaced by/4VP.46 for sheet compressed asbestos gaskets (2) MIL-G-21032E, Spiral Wound Metallic Asbestos (not listed in specification but used for steam piping joints) (3) MIL-P-2863, Packing, Condenser (4) MIL-P-17303C, Asbestos Jacketed Packing Specifications should be changed to reflect new non asbestos gasket specifications. There are currently non asbestos substitutes; however, in lieu of requests for acceptance on each contract we are involved in, we would like specification alternatives that would permit substitution without extensive administrative effort. We believe there must be comparable requests for many other types of equipment and piping applications used for Navy and 000 contracts. For your reference we have attached letters we have received. We are asking our vendors to supply alternates but we would like to use the specification that the Navy has selected. Enclosure: A. Gallagher Fluid Seals letter dtd April 11, 1985 ,B.
