Metallic Manually Operated Gas Distribution Valves

Published by: 2017-01-01 / 2017-01-01 / 15 pages
The purpose is to provide a Standard Practice for metallic valves used in fuel gas piping systems which are manually operated both above and below ground.

This Standard Practice covers Metallic Gas Distribution Valves designed for operation at any pressure from 0 psig to a maximum of 285 psig, at operating temperatures ranging from -20°F to 150°F, and from sizes 1/2 to 12 NPS.

Corrosion Resistant Gate, Globe, Angle and Check Valves with Flanged and Butt Weld Ends (Classes 150, 300 & 600)

Published by: Manufacturers Standardization Society / 2013 / 18 pages
1. SCOPE

1.1 This Standard Practice covers Classes 150, 300
and 600 corrosion resistant alloy gate, globe, angle
and check valves with flanged and butt weld ends
which are constructed of pressure containing parts,
including materials that conform to ASME B16.34.

1.2 This Standard Practice covers additional
construction requirements for corrosion resistant
valves not covered by ASME B16.34. Such valves
are made from corrosion resistant alloys whose
properties are uniquely suited to the service into
which they are placed. Chemical process and
cryogenic fluid service constitute two such
applications.

Quality Standard for Steel Castings and Forgings for Valves, Flanges and Fittings and Other Piping Components-Magnetic Particle Exam Method

Manufacturers Standardization Society / 01-Dec-2012 / 9 pages

This Standard Practice provides methods and acceptance standards for the "non-destructive" magnetic particle examination of ferritic steel valves, flanges, fittings, and other piping components by use of dry magnetic powder or wet magnetic particles. It is applicable to the examination of repairs and the initial examination of castings and forgings.

Connecting Joints Between Tapping Machines and Tapping Valves

Manufacturers Standardization Society / 01-May-2012 / 15 pages

This Standard Practice covers the
dimensions which define the interface between
drilling/tapping machine adapters and tapping
valves; including clearances for the pilot drill
and cutter. This 'interface' or 'connecting
joint between tapping machines and tapping
valves' will be abbreviated as 'joint' in this
Standard Practice. The positioning recess and
mating raised face of the connecting flanges or
end connections, between machine adapters
and tapping valves, serve to ensure proper
alignment of the machine adapter onto the
tapping valve, without affecting the strength of
the joint. Only flanged, mechanical joint,
push-on, asbestos-cement, and radial
compression connections are included within
this Standard Practice.

Plastic Industrial Ball Valves

Manufacturers Standardization Society / 01-May-2012 / 10 pages

This Standard Practice establishes
requirements for plastic industrial ball valves
in nominal pipe sizes (NPS) 1/2 through 4,
designed for general industrial systems for the
distribution of pressurized liquids that are
chemically compatible with the piping
material. It reflects the industry practice for
the design, manufacture, and application of
these valves.
