Flanged joint
ISO 10628-2 (groups 24-25, fittings and piping) / PIP PIC001 / ASME B16.5
Drawn as
Two short parallel bars across the pipe, close together.
Meaning
Bolted flange connection, usually shown only where it matters: equipment nozzles, spool breaks, spec breaks and maintenance breaks. Becomes flanged-joint.
Variants
- A single bar is a flange face at an equipment nozzle
- Look-alike: union has a shorter third bar in the middle
- Look-alike: a flange pair with a figure-8 drawn beside it on a short stem is a spectacle blind (spectacle-blind-offset), not a plain joint
