Wobth Kanbas Citt Los Angeles Memphis Milwaukee New Yobs Philadelphia San Francisco In Canada: Flexonics Corporation op Canada, Ltd., Brampton, Ontario FLEXON EXPANSION COMPENSATORS FOR STEAM AND HOT WATER HEATING SYSTEMS' Model L for pressures to 60 psig The Flexon Model L Expansion Com pensator consists of a two ply phosphor bronze bellows with copper tube end connections enclosed in a protective shroud of brass. It is especially designed for control of expansion in finned type convectors, baseboard, radiator or heat ing supply and return lines. Sizes from % in. through 2 in. Suit able for temperatures from --60 F to 250 F and for pressures up to 60 psig. A single unit will handle motion up to K in. Qi in. compression, K in. extension). Available with all commonly used fit tings. Model H for pressures to 175 psig The Flexon Model H Expansion Com pensator is used primarily on vertical risers for high pressure steam and hot water lines. However it may also be used on horizontal runs. The Model H con sists of a corrosion resistant Flexon Bellows enclosed in an all-welded steel housing. The unit is provided with a positive anti-torque deviee to prevent possible bellows damage during installa tion. Sizes from % in. through 3 in. Suitable for temperatures from --60 F to 750 F. Maximum test pressures 50 psi over working pressures shown in table. A single unit will handle motion up to 1% in. (1K in. compression, in. exten sion). Mild steel male NPT pipe nipples on both ends are standard. Ground joint unions or weld ends are optional. Sizes and Dimensions Overall Length, Max. OJD., Tube in. in. Size (in.)

Low Anchor Load Requirement Reduces Installation Cost. Industry Benefits from Aircraft Engineering and Research. ROUND rKrKEVKF'TLEX BT5e-1ll1o--w---s- are made of lami nated Stainless Steel, multiple ply (usually 2 ply or more) for greater strength with minimum force required to move bellows. The minimum force to move 7 Q Keflex Bellows greatly reduces the need for additional anchoring above that required to handle line pressure thrust force as the force to move Keflex 7 Q only is always less than 100 lb. Type 7Q FLAT KEFLEX FLAT GUIDES offer so many advantages it is difficult to mention them all. Briefly. The KEFLEX FLAT OUT SIDE GUIDE (shroud) is made of brass USUALLY formed square of required length--one unit end will telescope over other unit end. The flat surfaces slide dver and in one another--practically eliminating possibility of torque as result of faulty installation. This ASSISTS PROPER GUIDING. STANDARD UNITS Pressure 300 psi Temperature 800 F Compression Force Less than 100 lb SQUARE KEFLEX SQUARE END FITTINGS are made of heavy, non-porous, square, bronze stock, and threaded tapered fe male pipe size. They are attached to the KEFLEX 7 Q bellows and the outside guides by silver brazing. The result is an easy moving expansion joint that will absorb either the slightest or the great est thermal pipe expansion and with practically no load on the anchors. The hpavy bronze ends, which will not crush during normal installations, assures safe and leakproof joints. Eliminates copper pipe buckling. Ask for Bulletin KQ-l For: 150 in.
