One of North America’s leading integrated designing, manufacturing and testing facilities for orifice plates.
We design and manufacture a variety of custom orifice plates from bore & bevel to bore & counterbore, segmental, eccentric and quadrant (quarter round).
Our bore & bevel orifice plates are machined at 45º angle to the desired edge thickness and typically beveled to 1/50 of the line I.D. or 1/8 of the orifice bore. In the bore & counterbore orifice plates we use a special method to limit the plate edge thickness.
Our segmental and eccentric bore orifice plates have offset bores to operate in conditions with gas or liquid steam entrained with solids. Quadrant bores are designed for fluids of high viscosity, such as heavy crudes, syrups and slurries.
