Malleable Iron Threaded Fittings: ANSI B16.3, Class 150, standard pattern, for threaded joints. Threads shall conform to ANSI B1.20.1. Steel Fittings: ASTM A 234, seamless or welded, for welded joints. Wrought-Copper Fittings: ANSI B16.22, streamlined pattern. Cast-Iron Threaded Flanges: ANSI B16.1, Class 125; raised ground face, bolt holes spot faced. Threads shall conform to ANSI B1.20.1. Steel Flanges and Flanged Fittings: ANSI B16.5, including bolts, nuts, and gaskets of the following material group, end connection and facing: Material Group: 1.1. End Connections: Butt Welding. Facings: Raised face. JOINING MATERIALS Brazing Filler Metals: AWS A5.8, Classification BAg1 (silver). Gaskets for Flanged Joints: Gasket material be full-faced for cast-iron flanges and raised-face for steel flanges. Select materials to suit the service of the piping system in which installed and which conform to their respective ANSI Standard (A21.11, B16.20, or B16.21). Provide materials that will not be detrimentally affected by the chemical and thermal conditions of the fluid being carried. PIPING SPECIALTIES Y-Pattern Strainers: 125 psig working pressure; cast-iron body conforming to ASTM A 126, Class B; flanged ends for 2-1/2 inch and larger, threaded connections for 2 inch and smaller, bolted cover, perforated stainless steel screen, and plugged blow-down drain. Flexible Connectors: minimum 150 psig working pressure, maximum 250 deg F operating temperature; stainless steel bellows with woven flexible bronze wire reinforcing protective jacket. Connectors shall have flanged or threaded end connections to match equipment connected; and shall be capable of 3/4 inch misalignment.
