ASME/ANSI B16 - Standards of Pipes and Fittings

ASME/ANSI B16 - Standards of Pipes and Fittings

The ASME B16 Standards covers pipes and fittings in cast iron , cast bronze, wrought copper and steel

ASME/ANSI B16.1 - 1998 - Cast Iron Pipe Flanges and Flanged Fittings
This Standard for Classes 25, 125, and 250 Cast Iron Pipe Flanges and Flanged Fittings covers], and liquefied petroleum (LP) gases (distributed as a vapor, with or without the admixture of air) or mixtures thereof.

ASME/ANSI B16.42 - 1998 - Ductile Iron Pipe Flanges and Flanged Fittings, Classes 150 and 300
The Standard covers minimum requirements for Class 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
• (c) marking
• (d) materials
• (e) dimensions and tolerances
• (f) blots, nuts, and gaskets
• (g) tests

ASME/ANSIB16.44 - 1995 - Manually Operated Metallic Gas Valves for Use in House Piping Systems
This Standard applies to new valve construction and covers quarter turn manually operated metallic valves in sizes NPS 1/2-2 which are intended for indoor installation as gas shutoff valves when installed in indoor gas piping between a gas meter outlet & the inlet connection to a gas appliance.

ASME/ANSI B16.45 - 1998 - Cast Iron Fittings for Solvent Drainage Systems
The Standard for cast iron drainage fittings used on self-aerating, one-pipe Solvent drainage systems, covers the following:
• (a) description
• (b) sizes and methods for designating openings for reducing fittings
• (c) marking
• (d) material
• (e) pitch
• (f) design
• (g) dimensions and tolerances
• (h) tests

ASME/ANSI B16.47 - 1996 - Large Diameter Steel Flanges: NPS 26 through NPS 60
This Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60 and in ratings Classes 75, 150,0300, 400, 600, and 900. Flanges may be cast, forged, or plate (for blind flanges only) materials. Requirements and recommendations regarding bolting and gaskets are also included.

ASME/ANSI B16.48 - 1997 - Steel Line Blanks
The 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.

ASME/ANSI B16.49 - 2000 - Factory-Made Wrought Steel Buttwelding Induction Bends for Transportation and Distribution Systems
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 differing requirements and materials that may not be appropriate for the restrictions and examinations described herein, and therefore are not included in this Standard.
