Corrosion Monitoring Function

The 03-220-20 coupon provides a stainless steel test specimen for exposure in a corrosion coupon rack or other appropriate monitoring arrangement. Comparing the recorded initial mass with the mass after exposure and cleaning can support corrosion-rate evaluation when an approved testing procedure is followed.

316/316L Stainless Steel Construction

The coupon is manufactured from 316/316L stainless steel, making it suitable for corrosion monitoring programs that specifically require this alloy. Results reflect the exposure conditions and testing method and should not be interpreted as a universal prediction of equipment service life.

Dimensions and Identification

The listed coupon dimensions are 2.5 inches long, 0.5 inch wide and 1/16 inch thick. A 1/4-inch mounting hole is centered 5/16 inch from one end. The supplier identifies a glass bead blasted finish, alloy identification and individual coupon numbering.

Typical Applications

• Industrial water treatment corrosion monitoring
• Cooling water corrosion coupon racks
• Process water system evaluation
• Stainless steel material loss monitoring
• Scheduled corrosion monitoring programs

Handling and Installation

Record the coupon identification and starting weight before installation. Handle the test surface carefully to avoid contamination. Install in a compatible coupon holder and follow the monitoring program requirements for exposure time, flow conditions, cleaning and final weighing.

Ordering Information

Order using Pulsafeeder 03-220-20. Confirm that the monitoring program requires 316/316L stainless steel rather than mild steel, copper or another coupon material.
