ORIFICE PLATES

Peterson Instruments' Orifice plates are made in house.  We use only 316 sst and machine them to meet AGA-3 MR 01-75 specifications.  Each plate has its heat number, bore, OD and material spec engraved and not hot stamped or acid etched to ensure this information on the outer edge is clear and legible for the lifetime of the plate.

At our Calgary warehouse we stock thousands of plates in all of the cat 500 bores for run sizes 2", 3", 4", 6" and some 8” plates.  We stock cat 520 plates in all bores for runs 2”, 3” and 4”.

Other sizes available on request.
