Orifice plate – segmental orifice plate

are used to flow-measure from aggressive and non-aggressive gases, vapors and liquids.
Construction: orifice plate for direct installation between flanges or measur flanges.
Designs than the quarter-circle nozzle or segmental orifice plate are available.
Marking on the handle-plate: Tag.No, nominal size, bore, material, + on the non-beveled side.

Orifice plate – segmental orifice plate
Nominal pressure: PN 10 to PN 400
Nominal size: DN 50 to DN 1600
Seals: according to DIN 19206 part 1, smooth
DIN 19206 part 2 and part 3
according to API and ANSI standards,
smooth and ring joint (RTJ)
Materials: Stainless steel normal, 1.4571

Other materials according to specification, or by application.
Material such as certificates of materials according to EN 10204 will be delivered.
The calculation of the orifice is corresponding to standard EN ISO 5167-1 and Directive 97/23/EC.

 

Standard orifice plate with single bore (single tappings)

This type is executed as carrier-ring with fixed orifice plate and bore according to DIN 19205. The orifice plate is not replaceable.
It can be delivered as an orifice according to DIN 1952, venturi nozzle, as quarter-circle nozzle or as a segmental orifice.
The orifice plate etc. can be welded or screwed into the carrier-ring or manufactured as a single piece. When using normal steel, the bore will be plated with stainless steel (1.4571).
The installation in the pipeline is between flanges. The length is standard 25, 40 or 65 mm.
The identification is done on the carrier-ring: Tag.No, nominal size, bore, material, + on the inlet side.
