Orifice Flange

Orifice Flange
Product Detailed
Orifice flanges are intended for use instead of standard pipe flanges when an orifice plate or flow nozzle must be installed.

General Description

Orifice flanges are intended for use instead of

standard pipe flanges when an orifice plate or

flow nozzle must be installed.  Pairs of pressure

tappings  are  machined  into  the  orifice  flange,

making separate orifice carriers or tappings in

the pipe wall unnecessary.

Thermocouple Instruments Ltd's orifice range of

orifice  flanges  covers  all  standard  sizes  and

ranges,   and   all   common   flange   materials.

Flanges  are  available  in  socket  weld  or  weld

neck form, and are typically supplied with two

½"  NPT  tappings  in  each  flange.     Jacking

screws to ensure ease of removal of the primary

flow element are provided.

Orifice  plates  and  flow  nozzles  can  also  be

supplied.   See individual Product Data Sheets

for more information.

Orifice flanges may also be supplied complete

with bolting and gasket kits.
