ORIFICE FLANGES & METERRUNS

Orifice flanges are manufactured as standard according to ASME B16.36, which means NPT flange tappings complete with plugs and jackscrews. In the case of an orifice assembly this can be completed with orifice plate, studbolts, nuts and gaskets. The flanges can be optionally executed with other possible process connections, such as SW, BW, plain-end or flanged welding nipples. This can be completed with valves, condensate pots and differential pressure transmitters.

Orifice Meterruns are fabricated in accordance with ISO 5167 requirements and several construction codes such as ASME B31.3 or Stoomwezen Rules for Pressure Vessels. Apart from flange tappings, the orifice flanges in can also be executed with corner, radius or pipe tappings. The flanges can be optionally supplied with dowel pins to ensure correct positioning of pipework up- and downstream of the orifice plate. Both orifice flanges and meterruns can be supplied in any required material complete with material certificates 3.1B or 3.2.
