The EMT-CIPA Corrosion Coupon is designed to measure the corrosion rates within pipes or containers by monitoring the annual degradation of the coupon. This method allows you to determine the corrosion rate of your pipeline system accurately. By using these coupons, you gain crucial insights into the expected lifespan of your materials. Corrosion coupons serve as practical tools that quantitatively assess the corrosion rates in active systems. Typically, the materials used for the corrosion coupons are identical to those used in the pipeline itself.

Our company, EMT, provides three different types of corrosion coupons:

Name	Strip Coupon	Multihole Strip Coupon	Disc Coupon
Applications	Commonly used for most evaluations.	Use with low-pressure access equipment or through narrow ports that a standard 3/4 inch wide coupon cannot pass.	These circular coupons work in multiple disc monitoring applications.
Size	3”*3/4”*1/16” (76.2mm*19.0mm*3.2mm)	3”*1/2”*1/16” (76.2mm*12.7mm*3.2) With mounting holes	Φ1.25”(31.8mm)Thickness 1/16”(3.2mm)

Corrosion Coupon Holder Options

We offer four distinct types of corrosion coupon holders to meet various application needs:

Disc Coupon Holder: Typically used to position the coupon against the inner wall of the pipe.
Multiple Disc Coupon Holder: Similar to the disc holder but designed to hold several coupons at once for broader data collection.
Strip Coupon Holder: Allows for the placement of strip-shaped coupons within the pipeline.
Ladder Strip Coupon Holder: Ideal for installing coupons at upper, middle, and lower positions within the pipe, with equal spacing between each to assess corrosion uniformly across different levels.

Functionality of Coupons in Corrosion Monitoring

Corrosion coupons are essential tools for directly measuring the rate of corrosion by evaluating material loss over time. They effectively mimic the materials used in pipelines or structures, providing critical data relevant to those materials. These coupons are invaluable for assessing the corrosive properties of specific environments and operational conditions. They also test the effectiveness of corrosion inhibitors and protective coatings. By gathering long-term data, corrosion coupons aid in the development of maintenance schedules and prevention strategies, ultimately helping to preserve the integrity and extend the lifespan of infrastructure across various sectors.

Selection Model of EMT-CIPA Corrosion Coupon

Corrosion Coupon Body

The EMT-CIPA Welding Connection Corrosion Coupon features a welded connection, available in various sizes to suit different applications. The base of these coupons ensures a secure and stable weld, minimizing movement and supporting heavier loads to maintain structural integrity.

When preparing to weld these bases, certain safety precautions are critical. Always wear a welding helmet, gloves, and fire-resistant clothing to protect against sparks and UV exposure. Ensure the area is well-ventilated to prevent the inhalation of dangerous fumes and gases. Additionally, wear safety goggles to protect your eyes from debris and intense light. Keep a fire extinguisher close at hand, clear the area of flammable materials, and verify that all equipment is properly grounded and cables are undamaged. Maintaining a tidy and organized workspace is also crucial to avoid accidents.

In addition to welding connection coupons, we offer various sizes of flange connection coupons. These are compatible with a wide range of pipe sizes and materials, offering versatile and strong connections that can handle significant pressure and stress. If you have specific material requirements for the coupon body or holder, please contact us. We are committed to providing the optimal solution to meet your needs.

Other Coupon Types

In addition to the standard EMT-CIPA type, our company also offers the EMT-CIPA type coupon and the EMT-RCC type retractable corrosion coupon. The EMT-RCC is designed to withstand temperatures ranging from -20 degrees Celsius to 120 degrees Celsius, demonstrating its capability to resist high temperatures. It can also handle pressures up to 2000 PSI, making it exceptionally robust for challenging environments.
