This Standard covers design, material, manufacturing,testing, marking, and inspection requirements for factory-made pipeline bends of carbon steel materials having controlled chemistry and mechanical properties,produced by the induction bending process, with or without tangents. This Standard covers induction bends for transportation and distribution piping applications (e.g., ASME B31.4, B31.8, and B31.11). Process and power piping have

This Standard covers pressure–temperature ratings,materials, dimensions, tolerances, marking, and testing for operating line blanks in sizes NPS 1 ∕ 2 through NPS 24 for installation between ASME B16.5 flanges in the 150, 300, 600, 900, 1500, and 2500 pressure classes.

(a) This Standard covers manually operated thermo-plastic valves in nominal valve sizes 1 ∕2 through 12.These valves are intended for use below ground in ther-moplastic fuel gas distribution mains and service lines.The maximum operating pressure (MOP) at which such distribution piping systems may be operated is in accordance with Transportation of Natural and Other Gas

This Standard covers pressure–temperature ratings,materials, dimensions, tolerances, testing, and making of flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections. Coverage is limited to the following: (a) welding neck flanges Classes 300, 400, 600, 900,1500, and 2500 (b) slip-on and threaded Class 300

This Standard applies to new construction and covers pressure-temperature ratings, dimensions, tolerances,materials, nondestructive examination requirements,testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and wafer or flangeless valves of steel, nickel-base alloys, and other alloys shown in Table 1. Wafer or flangeless valves, bolted or through-bolt types, that are installed between

This Standard for cast iron threaded drainage fittings covers (a) sizes and method of designating openings in reduc-ing fittings (b) marking (c) material (d) dimensions and tolerances (e) threading (f) ribs (g) coatings (h) face bevel
