Cosasco corrosion and erosion monitoring coupons are specially made for corrosion and erosion studies and are manufactured to the most demanding standards. Generally, corrosion coupons should be of an alloy the same as, or similar in chemical composition to the pipeline or vessel that is being monitored.
The Cosasco Ladder Strip Coupon Holder can suspend six strip corrosion coupons (3 pair) from a single access fitting point. The Coupon Holder has a left-hand threaded nut which attaches it to the bottom of the Cosasco Solid Plug Assembly and also serves as a primary packing retainer.
Cosasco corrosion coupons are manufactured from certified materials in a wide range of metals and alloys. The surfaces of the coupons are free from scratches, tool marks, pits and other imperfections that would create measurement errors. The coupons are stamped with a unique serial number with a low stress stamp. Each coupon is packaged in an envelope treated with VCI (Vapor Corrosion Inhibitor) which prevents corrosive attack during shipment and storage.
Multiple Disc Coupon Monitoring is available for pipes with diameters of 6″ or more. This pipeline corrosion protection method offers the following advantages: inherent orientation parallel to flow, greater surface area at a specific level, greater quantity and variety of coupon materials, easier monitoring in stratified or multi-phase flow, and corrosion coupons location in recess area of access fitting for monitoring in gas pockets or stagnant areas.
The coupon holder assembly is designed for maximum strength/insertion length and to reflect the process conditions the polymer sheath will be exposed to under normal production conditions over time.
Cosasco corrosion coupon strip holders for the 2″ system are used to suspend either 3″ or 6″ corrosion coupons in the area to be monitored. Attached to the bottom of the solid plug by means of a left-handed thread, the coupon holder also serves as a primary packing retainer.
Model 6210 Coupon Holder Assemblies provide a retractable means of coupon monitoring in processes at pressures up to 1500 PSI/10.3 MPa and temperatures up to 500º F/260º C. Insertion of the coupon holder can be adjusted to permit coupon positioning at precisely the desired point within the process.
