Specialists at Rosneft’s Volgograd Scientific Institute have developed and patented a device for holding coupons*, which are samples used to study corrosion in metal pipelines and production facilities. The unique design of the new coupon holder enhances safety and improves the quality of corrosion testing.

Corrosion testing involves conducting studies under various operating conditions, including high temperatures and pressures. Such testing is necessary for the purpose of forecasting the remaining service life of equipment and planning maintenance, with a view to minimising the risk of failure.

The use of coupons to diagnose and monitor the condition of technological installations is a well-established practice. The new coupon holder has been designed to facilitate the speedy and convenient replacement of samples, thanks to its quick-release tip.

The positioning of samples is also key to improving the quality of corrosion tests – coupons can now be fixed in a precisely specified position. The special unit for draining liquid and gas ensures the device operates safely – the coupon is removed without the operator needing to take any additional action. The combination of these solutions ensures that the development is superior to its counterparts.

Organising high-quality monitoring of equipment condition and forecasting its service life enables the Company to ensure smooth production operations, safe working conditions, while minimising its environmental impact.

* Coupons are small metal plates that are exposed to the internal environment during the operation of pipelines or process installations. This exposure allows us to determine the rate and type of metal corrosion.
