Smith-Blair Style 913 Steel Flanged Coupling Adapter - 3-24 in

The Smith-Blair Style 913 flanged coupling adapter (FCA) is a fabricated steel plain end x flange adapter that joins plain-end pipe to flanged valves, fittings and meters, including butterfly and wafer valves, 3 to 24 in nominal. The flange is the same size as the pipe: ANSI 150 lb flat face on 3-5 in and AWWA C207 Class D (150 lb drilling) on 6 in and larger. A Flexi-Coat epoxy steel sleeve carries a Nitrile gasket and a ductile iron follower (3-12 in) or heavy steel follower (14 in and up), sealing on steel, stainless, ductile iron, cast iron, asbestos cement, PVC or HDPE pipe.

It replaces cracked pipe or spooled flanges with no field fabrication and gives a quick way to remove and reinstall a flanged fitting in line. Choose the nominal size and pipe OD, then alloy, 304 or 316 stainless hardware, then the standard adapter or, on 3-12 in, the anchor-stud build that holds the plain pipe end.

Application: joining plain-end pipe to flanged valves, meters and fittings of the same nominal size, and replacing cracked pipe or spooled flanges, 3 to 24 in.

Key Features

• Working pressure up to 150 PSI; higher-pressure designs built to order
• Flange matched to the pipe size: ANSI 150 lb flat face 3-5 in, AWWA C207 Class D 6 in and up
• Optional anchor studs on 3-12 in secure the plain pipe end
• Coupling end relieves stress, absorbs vibration and accepts up to 2° deflection
• Certified to NSF/ANSI 61 and NSF/ANSI 372; meets applicable portions of AWWA C219

Up to 150 PSI, according to size and design; higher-pressure designs are built to order. In service the allowable pressure also depends on pipe type and condition, service conditions and workmanship. The anchor-stud PSI figures below rate the studs' thrust, not the FCA.

Materials subject to change by the manufacturer.

Carbon steel, stainless steel, ductile iron, cast iron, asbestos cement, PVC and HDPE pipe. Pipe stiffeners are required on thin-wall PVC and HDPE.

Choose the size in the first option and the hardware in the second; the anchor-stud choice and part number show in the third.

The rating is the thrust the studs hold, not the FCA. Anchor-stud builds run 3-12 in; larger sizes and other OD ranges on request.

• Clean about 12 in of the pipe end, keeping the gasket bearing surface free of blemishes, and lubricate the pipe and gaskets with a soap-and-water solution that meets the water and pipe supplier's requirements.
• Slide the follower flange, gasket and adapter body onto the plain end in that order, bolt the body to the companion flange, then seat the gasket against the body and bring the follower up to it.
• Keep the end gap between the pipe and the companion flange at least 1/2 in and no more than 3 in on 7-9 in bodies or 5 in on 10-15 in bodies; deflection is limited to 2° with 3 in of pipe engagement.
• Torque the follower bolts in two passes to the values in the instructions with a calibrated torque wrench, and recheck after the line is pressurized.
• Anchor-stud builds: insert the pipe at least 1 in past the anchor-stud boss, drill through the pipe wall using a 1/2 in or 1 in NPT nipple in the boss as a guide, and set each stud with pipe thread compound, not tape; the pipe cannot be moved afterward.
• Anchor the pipe: the FCA seals around it but does not restrain it, and Smith-Blair requires anchor studs or other proper anchoring to restrain pipe movement and prevent pull-out.
