Corrosion Coupon Kits

Top Corrosion Coupon Suppliers

We manufacture monitoring corrosion coupons in any configuration, and from any materials, whether provided by us or by the customer. Evaluation of welds can be made by utilizing corrosion monitoring coupons with weld beads applied, or evaluation of scale by use of strip scale coupons. All coupons are certified in writing to show serial numbers, weights (furnished in grams to four decimal points), dimensions, material, and surface finishes. As a leading corrosion coupon manufacturer, SMARTCORR^® coupons are individually packaged in moisture-resistant, vapor phase-inhibited envelopes with a corrosion-free shelf life of one year.

We are top corrosion coupon suppliers, offering you an integrated system for measuring the corrosion found inside your pipeline. To learn more about what makes us the industry’s leading corrosion coupon manufacturers, get in touch with us today.

Types of Corrosion Coupons & When to Use Them

The most common types of corrosion coupons include:

• Strip coupons: These consist of thin metal strips that are inserted into the pipeline. They are the most economical option but are limited in terms of the information they provide. They’re best used in general corrosion monitoring situations and to calculate general weight loss in the pipeline.
• Disc coupons: This type of coupon sits flush with the wall of the pipe, rather than being inserted directly into the process flow. This means they do not interfere with the flow of materials. They’re typically used in situations involving multi-phase flow and when corrosion needs to be monitored across the diameter of the pipe.
• Ladder coupons: Designed with multiple points of corrosion measurement, these coupons are used in situations where technicians need to take more than one reading to determine the extent of corrosion, such as pipelines with large diameters.
• Scale coupons: These include a series of holes of various sizes drilled into them. The purpose of these holes is to collect scale to help technicians determine the level of buildup that may be occurring throughout the pipeline.

Frequently Asked Questions

How do corrosion coupons work in a pipeline system?

Most often, coupons are inserted at strategic points throughout the pipeline, where they make direct contact with the process flow. After 90 days, they are removed and measured to determine the amount of corrosion they experienced. This provides technicians with valuable information they can use to make decisions about maintaining or replacing sections of the pipeline to prevent failure.

What alloys are best for specific industrial environments?

In general, corrosion coupons should be made from the same material as the pipeline. This is because otherwise they won’t provide an accurate reading of the corrosion rate of the infrastructure. If you have questions about which materials you need for your corrosion coupons, the experts at SMARTCORR® can help.

How long should corrosion coupons remain in service?

It’s recommended that coupons be left in the pipeline for 90 days to get the most accurate assessment of corrosive conditions inside the pipe.

Can coupons be reused after lab analysis?

No. Corrosion coupons are not intended to be used more than once. Attempting to reuse a coupon will result in inaccurate measurements and negate their entire purpose.

What is the expected shelf life of a sealed coupon?

In most cases, sealed corrosion coupons can be kept in storage for up to one year before they begin to lose their efficacy.
