Orifice Plates
Orifice plates are used with an orifice fitting or orifice flange unions to measure the flow of gas. The differential drop between the high pressure side and low pressure side of the fitting along with pipe diameter and orifice size will determine the flow of gas going through the fitting. The differential pressure drop is measured with a flow recorder that you can purchase from us and is under the Recorder section on our website. The orifice fitting parts are direct replacement parts for Daniel Senior Orifice fittings. New Style 14.3 and Old Style AGA3 Orifice seal rings are also available in Nitrile and HNBR, other materials are available upon request, please call for quote.
OGME carries in stock 316SS universal orifice plates that are in the BETA ratio from .15 thru .75, other materials available upon request. We can also provide paddle type orifice plates in a variety of different materials and can ship two days after order is placed. Please see Orifice Plate Document for more information.

ORIFICE PLATES
Our first priority when manufacturing orifice plates is exactness; all of our products are manufactured using state of the art measuring equipment and processed in temperature controlled facilities. We strive to ensure that our customers receive only top of the line precise merchandise. Whether it be the Brown and Sharp Coordination Machine, which is used to check bore diameters at 68 degrees, the Sunnen Dial Bore Gauge, which is used to check diameter to one ten thousandth of an inch, or the Mazak Optronics CNC Laser Cutter, which is used to cut orifice plates to one ten thousandth of an inch, we guarantee our customers receive high quality products.
Each of these plates is carefully manufactured to meet or exceed standards set by I.S.A., A.P.I., A.G.A., A.N.S.I., and A.S.M.E. recommendations. All precision bored orifice plates are available with prompt delivery service and obtainable in both universal and paddle type configurations with concentric bores. Standard material and thickness for orifice plates is 1/8” thick 316SS, but we can offer these plates in a variety of different thicknesses and materials including 304SS, Monel, and Hasteloy, just to name a few, others are available upon request. Please call one of our qualified sales associates to attain your orifice plate quotation today, or if you have any questions we would be glad to assist you.
