ORIFICE PLATES & FLANGES

ORIFICE PLATES & FLANGES

Orifice Plates are the most commonly used differential pressure measurement device and are applicable for measurements in gases, clean liquids, and low velocity steam.

Orifice plates allow for relatively easy installation and replacement if necessitated by changes in process parameters or life cycle deterioration.

Armstrong supplies components for a typical orifice meter installation including flange unions, gaskets, orifice plate, and appropriate pressure tap sets.

Armstrong manufactures the orifice plates under strict control with high quality in observation with ASME and ISO 9001 certification standards. The orifice plates also meet AGA, ISA, ANSI, and API applicable codes.

Nondestructive testing and special service options available.
