TVPCAL INSTALLATIONS 3 TFE Piston Cup Packings Cbemlon TFE Cup Packings are precision machined in a wide range of sizes^For designers of new equip ment, it is recommended that the standard, cup sizes referred to in the drawing and in the accompanying table at the right be followed whenever possible, since they are the most popular sizes in use today. It is well to remember that the hole size ("C" dimen sion) is minimum only and can be ordered larger as required. If unable to use standard cup sizes shown, Crane Packing Company can manufacture to any size. DESIGN and INSTALLATION The drawing show s a typical exam ple o f a single acting and a double acting unit that includes the follow er plate and spacer. D esigning the plunger with a shoulder cut on the bottom a c c o m p lis h e s a tw o-fold purpose: (1) by c e n tering the cu p on the plunger proper allow ance for com pression of the cup bottom is made, and it is prevented from w orking lo o se under pressure and (2) undue com pres sion of the cup base by m echanical o r actuating pressure w ill force the heel of the cup to bind against the cylinder wal) 2nd greatly re d u ce packing life. D im ensions for sh oul der " E " (drawing at right) should allow for proper com pres sion of the cup bottom and prevent leakage under the inside follow er plate. W here sh ouldered piston rods are used, it is recom m ended that a T F E O -ring static seal be in sta lle d to prevent leakage along the rod. This w ill elim inate the necessity of em ploying the more expensive tapered piston rod and pis ton assem bly. W hen large diam eter cups are used (4" O.D. o r over), several equally spaced bolts or screws are recom m ended in o rd er to secure the cup installation firm ly in p la ce . A ll b o lts sh o u ld be uniform ly tightened to insure even com pression on the cup bottom. CLEARANCES It is re co m m e nde d that all installations be m ade with close clearances and with square corners to prevent cup extru sion. The sp a ce r or back follower plate should have a good fit in the cylin d er, as this plate supports the cup heel. E x cessive clea ra n ce between the sp ace r and the cylinder wall results in early cup failure because of the extrusion of the heel of the cup into the clearance gap. Clearances resulting from the bore diam eter (cup size nominal) and shown in draw ing as " B " diam eter are recom m ended for normal operating pressures up to 2000 PSI, T he in sid e fo llo w e r plate sh ould ha ve clea ra n ce as In dicated by " A " diam eter to prevent pinching of the lip against the c ylin d e r bore.

Th ey offer many advantages over other type packing ring sets in both sp a ce savings and economy. 1, Conger stroke can be obtained from shorter cylinder length. 2. Adapters or sp ecial end rings are not required. T h is not only substantially contributes to space savings, but also eliminates the cost of these non-sealing elements. 3. Pedestal design of the rings controls the fixed height of the packing set to eliminate the need for gland adjustment. Expensive space adjusting gland follower systems are not needed. The pedestal de sign also assures independent action of each seal ing lip. Com pression adjustment against adjacent rings is not required for initial or subsquent sealing. 4, A ll rings are identical. There is no need to stock as sets. ( M ini-T-Pak Rings can. be furnished in both homo geneous rubber and fabric reinforced materiais in a variety of com pounds to cover a wide range of serv ice applications. (See back pages.) W hile basically designed for hydraulic cylinders, they are also adapt able to pump rods and plungers, compressors, lubrica tors and many other reciprocating motion applications. Recommended finishes for contacting metal surfaces are 16 R M S for dynam ic and 32 R M S for static. M ini-T-Pak R ings are manufactured from syn thetic rubber compounds or by carefully folding cotton duck cloth or asbestos cloth frictioned with a synthetic rubber binder to the required size. The pre-form is then precision molded and vulcanized under heat and pressure to form the proper size. SPACE COMPARISON M fni-T'Pak Rings are far more compact than standard ". V-rings. Note that male and female adapters, which have '.< ho sealing function and add to cofit, are not required.

They are manufactured by an exclusive John Crane process in which interlaced cotton cords are impregnated with therm o-setting resins and m olded under heat and pressure to desired shape and size. The result is an interwoven construction that reinforces in all directions and eliminates the fracture and chip prone "p aths" characteristic to the layer construction of other molded and machined phenolics. This advantage, plus the Inherent structural strength of CraneIHe " M '\ permits the use of these adapters and support rings in place of expensive metai types. They actually outwear bronze and at the same time provide an excellent low-friction load carrying support surface that will not score the rod or the bore of the cylinder, Cranelite "M " Adapters and Support Rings greatly increase the life of V-ring packings by preventing deformation due to mechanical loads and also prevent extrusion of soft packing materials. They are ideally suited for use in hydraulic and pneumatic systems and can be used with the m ost fire-resistant hydraulic flu id s, including phosphate-ester types. Pressure range is up to 5000 psi,, temperatures to 200 F. S ize s are available up to 8" O .D ., engineered to your requirem ents.

Depending on the thickness of the gasket re quired, multiple layers of "GrafoiF' graphite and stainless steel are used. This composite construction provides a stronger gasket and in no way affects the excellent corrosion-resist ance and high-temperature properties of the graphite component since "GrafoiF' graphite is devoid of fillers or resins. The metal-inserted gaskets are available for pipe sizes froml/z to 20 inches, in thicknesses of 1/32 and 1/16 inches for 150, 300, 600, 900 and 1500 pound flanges. The gaskets are self centering when positioned by the flange bolts. Temperature extremes have no adverse ef fects on "GrafoiF' gaskets; dependable per form ance is assured from 1600CF in neutral or reducing atmospheres, down to -4 0 0 F. No cold flow characteristics are exhibited and there is no em brittlem ent of the "G ra fo iF ' material. Although "G ra fo il" metal-inserted gaskets will not vu lca n ize or bond to flan g e surfaces, "G rafoil" graphite particles may adhere to the flange faces. Parting the flanges, however, poses'no problem since the lam inar construc tion of the gasket facilitates a clean break away, Any rsidue is readily removed with a wire brush or metal wool.

These gaskets are O.D. dim ensioned to be seif-centering v/ben sup ported by the flange bolts. Tem perature extremes have no adverse ef fects on G R AFO iL gaskets; dependable per form ance is assured from 3000F in neutral or reducing atmospheres, down to --4009F, No cold flow characteristics are exhibited and there is no embrittlement. Although GR AFO IL gaskets do not vulcanize or bond to flange surfaces, they may adhere to the flange faces. Parting the flanges, how ever, poses no problem sin ce the lam inar con struction of the gasket facilitates a clean break-away. Any residue is readily removed with a w ire brush or metal wool. This catalog is intended as an aid in designing flanged gasketed joints and as a guide in solv ing field gasketing problems.

It has outstanding corrosion resistance at temperatures from cryogenic to molten metal and retains com pressibility at such temperatures. At high temperatures, the adhesive backing carbonizes to become part of the gasket itself-- possible leaching out of the adhesive presents no problem. "G rafoil" tape resists attack by most common organic and inorganic reagents as detailed in our Catalog Section covering corrosives handled. "G rafo il" tape is the ideal do-it-yourself gasket material fo r easy field fabrication o f gaskets on flanges, ** The new crinkle "G ra fo il'' tape permits forming gaskets down to 3 inches in diameter with little or no distortion. The plain "G ra fo il" tape is recommended for form ing gas ket diameters 18 inches and over and for specially shaped gaskets having long straight runs. The'tape is merely laid out along the flange and may be built up to whatever m ultiple of its,015-mtl thickness is desired. The adhesive backing bonds securely to the flange as well as (ayer-to-layer. No longer is it necessary to stock, transport and m anipulate an assortm ent of large pre formed gaskets to accommodate a variety of size require ments. Order "G ra fo il" tape in either of two convenient size rolls-- Vi inch wide by 25 feet long or 1 inch wide by 50 feet long--from our sales office. INSTALLATION INSTRUCTIONS F O R S IN G L E ,0 1 5-M IL T H I C K G A S K E T 1, Brush o ff any rust or foreign particles. Wipe flange surface thoroughly with rag soaked in acetone or other suitable solvent to remove grease or oil. 2, Insert fingernail between the paper backing strip and the tape and strip paper back three to six inches as illustrated. Draw reference line on flange and press squared-off end of tape against it. 3, Now, sta rt laying the tape along the face o f> the flange, peeling the paper backing as you go. To prevent the adhesive surfaces of the tape from doubling back on themselves and sticking to gether, strip av/ay only a few inches of paper at a time as shown. 4. When the starting point has been reached, lap the tape not m ore than Vie inch and cut with a sharp blade as pictured. 5. When using plain tape, it may be desirable to> ^ f roll it with a short length of smooth pipe to iron | p * out any w rinkles, (This step is rarely necessary with the crinkle tape.) FOR MULTIPLE-THICKNESS GASKET, ADD STEPS 6/7 AND 8 6, When the starting point has been reached, do not cu t the tape. Roll out the tape already laid down, using a short length of smooth pipe to iron out the wrinkles. 7. Now repeat step 3. Be sure that the top layer is posi tioned exactly above the first layer before contact is made. Once the adhesive touches the tape, It is impossible to separate the layers without tearing them. 8. Repeat steps 6 or 7, depending on the num ber of layers of tape to be laid down, and fin ish with steps 4 and 5. * U .S .

Exp ansion o f en trap ped a ir a t high tem peratures presents d an g er of gasket rupture. Gaskets `'John Crane" Chemlon Gaskets offer many practical advan tages over gaskets of other materials. Made of DuPont Teflon, they are impervious to all acids, alkalis, solvents or corrosives (with the exception of molten alkali and fluorine under ex treme conditions). Within their wide tem perature range (-120DF. to -j-500F.)f they are practically indestructible-- thereby reducing maintenance, down time and replacement cost to an absolute minimum. The excellent anti-stick characteristic of Teflon permits easy disassembly of the gasketted joint at any time without tearing or pulling. These properties, combined with durability and toughness, permit the re-use of Chemlon Gaskets time after time--a decided savings factor on applications requiring constant joint breaking for cleaning or equipment replacement. "FreeFlow" Gaskets-Construction Chemlon "FreeFlow" Gasket design eliminates: 1) flow re striction and turbulence in the line; and 2) danger of rupture at high temperatures due to air entrapped between the gasket insert and Chemlon envelope. (See diagrams at left.) Con struction also permits the gasket face to lie flat, whereas, in the "wishbone" type, compression of the insert against the inside wall of the gasket causes undesirable flaring, buckling i and wrinkling. These gaskets also provide the necessary resilience to as sure a leak-proof seal regardless of temperature change. This resilience is provided by an insert material ranging from soft rubber to asbestos, depending on type of piping and tempera ture conditions. "FreeFlow" Gaskets are available for a wide variety of pipe applications, including glass lined, porcelain, Pyrex, iron and steel; also for standard and special connections on such equip ment as reactor kettles, retorts, distillation columns, nozzles and sanitary couplings.

Sizes are available to meet every application. Solid gasket construc tion offers the simplest and most economical sealing method and is recommended whenever there is little or no temperature variation. When not confined, they may be used on low pres sure applications up to 300 psi. or, when properly confined, on operating pressures up to 30,000 psi.

It is completely non-toxic, and its service range is practically unlimited--from water and food products to destructive chemicals, solvents and acids, liquid or gas. AS A GASKET--Use Zip Joint on flanged connections, tanks or other pressure vessels, pump housings and all other similar mating faces. To make up a joint, it is only necessary to cut off and position a length just within the bolt circle (as in the case of a flanged connection) and twist the ends. Then reassemble mating faces in same manner as with other type gaskets. (When it is necessary to hold Zip Joint in place while making up the connection, this is easily accomplished with Zip Joint or other brand gasket adhesive.) AS A PACKING--Use Zip Joint for leakprooflng valves, faucets and similar gland applications. Just remove the old packing and wrap Zip Joint around the stem to the depth of the gland (as in the case of a valve). Screw down gland follower to tightness necessary to seal. Zip Joint is available in %rin. dia, x 25 or 50-ft. lengths; %2-in. dia. x 25-ft. lengths packaged in a self-dispensing container designed for tool box or maintenance bench use. It is fed from a coil through a hole in the top of the container where it is always available for pulling out and cutting off to any desired length. It is also available in %-in. sq. or Kc-in. dia. in either 5 or 25 ft, lengths. S' , G The fastest way to make a gasket-- any size, any shape O Eliminates cutting or purchasing gaskets to size and shape G Equally effective as a valve or faucet packing Simple and d e a n to in sta llsaves time and money G Has practically no liquid or gas service limitation G Withstands temperatures from --400 to +500F., pressures to 500 psiJ AH S izes Now Available With Handy Zip-Clip Cutter One cu tter is furnished with each 6-can car ton ofZipJoint.
