EDI CEO, Jim Diamond will be guest speaker

Jim Dimond, President of Electrochemical Devices, Inc., will address the Western New York corrosion committee on Thursday December 13th at 10 AM. The meeting will be held at:

Leisure’s Restaurant
6001 Big Tree Road
Lakeville, NY 14480

Title: Coupon Technology – An Overview

Jim will address the reason for using, where to use, and where to not use Cathodic Protection Coupons. He will discuss installation procedures as well as proper interpretation of data collected from Cathodic Protection Coupons. He will explain advantages of the Concentric Coupon with emphasis on the elimination of an IR component even where there are local current sources. He will explain interrupting CP current with a magnetic switch.

Prior to becoming President of EDI, Jim was president of Dimondale Co. Inc. which designs and manufactures cathodic protection products. Previously, he oversaw reference electrode manufacturing for Harco, Inc. He has over 40 years’ experience in cathodic protection including product design, manufacturing, and field engineering.

Electrochemical Devices, Inc. (EDI) was founded in 1986 and specializes in the design and manufacture of a variety of products for monitoring and controlling corrosion, including cathodic protection coupons. They provide the concentric coupon and a magnetically operated switch to connect the coupon and structure.

TN 1 How to measure tube sheet potentials

The potential across a tubesheet under cathodic  protection can show large variations from one location to another. Different waterboxes of the same apparent design can produce different potential distributions. Areas with excessively electronegative potentials can cause hydrogen damage to titanium or ferritic stainless steel tubes. Other areas may have potentials insufficiently negative to adequately protect the copper alloy tubesheet. These potential gradients cannot be detected by a reference electrode mounted on the side wall of the waterbox.

EDI’s Model TE Tubesheet Mounted Reference Electrode is designed to mount any place on the face of a tubesheet. They are shipped with a double tube plug which is inserted into the end of a condenser tube and tightened. Tube plugs are available for common tube sizes between 5/8 inch and 1-1/4 inch. The electrode’s lead wire terminates in a waterproof connector which plugs into a mating connector on the Model TW wire which has been affixed to the tube sheet face.  This attachment system allows the electrode to be easily removed during scheduled outages.  For additional information, visit EDI website.
