ArcelorMittal Europe – Flat Products
Coiled tubes can be up to 18 kilometres in length
Although the rejection rate for ArcelorMittal’s oil and gas grades is at such a low level it is a reference for the market, the mill at Fos-sur-Mer decided to install an automatic surface inspection system (ASIS) on the pickling line. The new system complements a surface inspection device on the hot rolling mill which has been continuously scanning coiled tubing products for several years.
“The new ASIS covers 100 percent of the surface area and notes contrast variations on the steel’s surface,” says Pierre Fize, global account manager for the coiled tubing market at ArcelorMittal International. “If a variation is detected, the defect is recorded and compared against a database.”
The cameras scan the whole surface and detect thousands of variations per coil. Accurate defect detection is achieved by training the system, and our certified quality operators, to accurately detect detrimental defects for every application, while running in full-production mode.
Kevin Elliott, product engineering manager for Quality Tubing
“Surface defects in the steels we use to make our coiled tubing are a cause for rejection, so the new surface inspection system will potentially save Quality Tubing hundreds of tonnes of steel annually,” says Kevin Elliott, product engineering manager for long-term ArcelorMittal customer Quality Tubing. “This is a pro-active approach from ArcelorMittal to improve the quality of an already high-quality product.”
It’s important to note that the ASIS doesn’t just benefit producers of coiled tubing Pierre Fize explains: “The ASIS we have deployed is used to scan all coils destined for exposed applications in the automotive, oil and gas, and other critical industrial markets. It will enhance the reliability of ArcelorMittal’s grades for the energy sector even further and contribute to the improved operational safety of oil and gas wells.”
ArcelorMittal Europe – Flat Products has recently revamped its service offer notes Henri Olivier, an account manager for ArcelorMittal International in Houston: “Timely deliveries are critical for coiled tubing producers as they often require a high volume of material over a short period of time. To address this, we have redefined our inventory strategy in France. This enables us to fulfil orders quickly. We have also established a dedicated team to track orders.”
