Micro’s Orifice
Plates have been in use since 1968. Micro offers a
complete range of orifice plates for a variety of
flow conditions for mounting between flanges, for
carrier Rings and with RJ Plate Holders for mounting
between RJ Flanges, for Carriers Rings and with RJ
Plate Holders for mounting between RJ flangs.
Weld in Orifices
Plates welded directly in branch pipes are also
undertaken for high temperature and pressure service
where flange mounting is not desired. Micro Orifice
Plates are designed and machined to perfection and
maintained accuracy and finish requirement of
International Standards e.g. AGA REPORT 3, ASME
MFC-3M, ASME 19.5, ISO 5167/BS1042, R.W. MILLER and
L>K> SPINK etc.
Micro Orifice
Plates are manufactured from quality materials e.g.
AISI 316, 316L, 304L, 321, Monel, Hastelloy C,
Duplex, Super Duplex, PTFE, etc.
Micro offers
following types of orifice:
| |

|
Concentric Square Edge Orifice
Plate: These plates are most
commonly used devices for flow
measurement for clean liquids,
gasses and low velocity vapour
(steam) flows. These plates have a
sharp, Square edged hole bored in a
flat thin plate with or without
bevel at the outlet depending on
size & usage. These plates are also
used for Restricting flows and
Dropping pressure. |

Conical Entrance &
Quadrant Edge Orifice Plate:These
plates are used for low Reynolds
number (generally below 10,000) and
give more constant / predictable
discharge coefficient. At. Lower
Reynolds numbers, the discharge
coefficient of square by as much as
30%. These are more usable for
viscous service. |
|
| |
| |
Segmental & Eccentric Orifice Plates
:
These plates are most useful where
there are substantial entrained
water / air and also of there are
suspension in the fluids. Of the
Orifice Plates The Orifice hole is
placed at the bottom and top for
liquids. |
