ASME Standards

This Standard establishes specifications for wrought copper and wrought copper alloy, solder-joint, seamless fittings, designed for use with seamless copper tube conforming to ASTM B88 (water and general plumbing systems), B280 (air conditioning and refrigeration ser- vice), and B819 (medical gas systems), as well as fittings intended to be assembled with soldering materials con-forming to

This Standard covers the following: (a) pressure–temperature ratings (b) size (c) marking (d) materials (e) dimensions and tolerances (f) threading (g) pattern taper

This Standard establishes requirements for castcopper alloy, wrought copper, and wrought copper alloy press-connect pressure fittings for use with hard-drawn seam-lesscopper water tubeconforming to ASTM B88 for piping systems conveying water. The press-connect system (tube, fitting, and joint) conforming to this Standard is for use at a maximum pressure of 1 380 kPa (200 psi)

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 applica-tions (e.g., ASME B31.4 and ASME B31.8). Process and power piping

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.

This Standard covers pressure–temperature ratings,materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60. Included are flanges with rating class designations 75,150, 300, 400, 600, and 900 with requirements given in both SI (Metric) and U.S. Customary units, with diame-ter of bolts and flange bolt holes expressed in inch

This Standard applies to new valve construction and covers quarter turn manually operated metallic valves in sizes NPS 4 1 ⁄ 4 and tubing sizes 1 1 ⁄ 4 O.D. These valves are intended for indoor installation as gas shutoff valves when installed in aboveground fuel gas piping down-stream of the gas meter outlet and

This Standard covers minimum requirements for Classes 150 and 300 cast ductile iron pipe flanges and flanged fittings. The requirements covered are as follows: (a) pressure–temperature ratings (b) sizes and method of designating openings of reducing fittings (c) marking (d) material (e) dimensions and tolerances (f) bolts, nuts, and gaskets (g) tests
