GROUNDING RINGS FROM EXOTIC
ALLOYS IMPROVE MAG METER ACCURACY
Collins all-metal grounding rings fit between flanges, helping to eliminate
unwanted noise and extraneous signals carried in fluids through lines pipes.
The rings are available with a variety of materials (including EXOTIC
ALLOYS) - 316 SS, Hastelloy* B&C, Monel*, Alloy 20, Titanium, Zirconium,
even Tantalum-in both 150# and 300# ANSI ratings.
Collins grounding rings are "paddle type" and are available in a standard
thickness of 1/8". Tantalum rings are also available in 1/16" thickness as a
cost-saving measure. They are also available in other styles and can be
specially fabricated according to the customer's own specifications.
These rings are frequently used in lined pipe where a grounding device is
required. For example, grounding rings are very effective when utilized
before and after a magnetic flow meter, fitting between flanges to
ground-out unwanted signals in the fluid that can cause inaccuracies in the
flow meter's readings.
Many of the exotic alloy grounding rings are maintained in stock in a
variety of materials up to 6". Other sizes are available up to 36" in 2-3
weeks after receipt of order.
