Collins manufactures a line of isolating grounding flanges that are equipped with a metal insert whose tip contacts the flowing medium and allows the user to ground out unwanted signals.

Custom Machining at Collins Instrument Company They are usually used with lined pipe where a grounding device is required as, for instance with magnetic flow meters. Typically installed in the pipeline before and after each flow meter, the flanges allow the user to ground-out unwanted signals that may be contained in the fluid and cause inaccuracies in the flow meter's readings.

The flanges are available in either Polypropylene or PVDF (Kynar*), and sizes range from 1/4" to 36" and in-stock sizes up to 6". They are also available in both 150# and 300# ANSI ratings.

Each isolating flange is equipped with a metal insert whose tip contacts the flowing medium. Our 1" thick flanges are equipped with a Monel* insert; the wetted portion of this insert in tipped in Tantalum. Other flange inserts can be custom-tipped with exotic metals such as Hastelloy* B & C, Titanium, Zirconium, Monel and Platinum.

Collins maintains Kynar isolating flanges in 150# ANSI type with Tantalum inserts in stock up to 6". Other sizes are available up to 36" in 2-3 weeks after receipt of order.
