3 Standard sleeve length couplings for cast iron, asbestos cement and steel pipe sizes. The Steel Coupling provides a means for connecting cast iron, steel, asbestos cement, plastic or other type of pipe with a coupling having a steel sleeve. The sleeve has a fusion bonded epoxy coating that provides protection from corrosive environments or line contents. Dimensions A wall thickness-- L B length--shown in listing A D D Overall coupling diameter-- L Overall coupling length Steel Couplings for Cast and 0/0 Ductile Iron Pipe Sizes Flexi-Coat Epoxy Coating and NSF 1 Buna N Gaskets thru Material Specifications SLEEVE: ASTM A-, ASTM A or carbon steel having a minimum yield of 0,000 psi. Fusion bonded epoxy coating provides an average mil protective coating and is suitable for potablewater systems according to FDA regulations. FOLLOWERS: Ductile iron ASTM A- or steel AISI C. Designed for high strength/weight ratio. Follower thickness determined by cou pling size. BOLTS & NUTS: High-strength, low-alloy steel with heavy semi-finished hexagon nuts. GASKETS: Nitrile (Buna N) NSF 1Compounded to produce superior stor age and performance characteristics while resisting water, acids, alkalies, most (aliphatic) hydrocarbon s and many other chemicals. Temperatures range - F. to 10 F. consult manufacturer for specific applications or other service temperatures. FINISH: Fusion bonded Flexi-Coat Epoxy.

Consult Smith-Blair regarding your specific coupling pressure requirements. Larger Sizes and Longer Length s Available. Consult Smith-Blair Engineering Dept. Penstock Couplings Pressure and other service conditions of penstock require that coupling design be modified to fit the requirements for each individual penstock. Smith-Blair engineers should be consulted for recommendations. Smith-Blair personnel are available for assistance in field supervision of the installation of penstock couplings or other large size couplings where required. Smith-Blair can produce couplings to fit any size pipe up to 0 inch dia. Bolting up of coupling being completed. Penstock coupled with 190 inch Smith-Blair couplings. 1
