ASME B16.11 Plugs and Bushings

2023-12-29 16:39:18 Hits:161 American Standards / Product Standards

ASME B16.11 plugs and bushings are integral components in high-pressure piping systems, designed to seal or close off openings in pipes, valves, or fittings. These threaded fittings, available in various materials and configurations, play a crucial role in controlling fluid flow and maintaining the integrity of the piping system.Our ASME B16.11 plugs and bushings are dimensioned according to B16.11 standard, including pressure-temperature ratings, dimensions, marking, tolerances and material requirements.

GENERAL NOTE:Dimensions are in millimeters.
NOTES:
(1)Cautionary Note Regarding Hex Bushings:Hex head bushings of one-size reduction should not be used in services where they might be subject
to harmful loads and forces other than internal pressures.
(2)Manufacturer’s applied tolerance shall ensure dimension will fit U.S.Customary tooling.
