The Dopeless® technology line at Tenaris’s facility in Argentina is the first in the company’s industrial system to integrate with a groundbreaking technology, a scrubber abatement system, to absorb the volatile organic compounds (VOC) emitted by its production processes.
The process works as follows: two fume extraction units located over the painting and drying/curing lines capture emissions and transport them to the treatment system inlet. Inside, water-soluble VOCs are retained by abatement mechanisms, a process involving the exchange of mass between a gas and a liquid. The organic compounds retained in the aqueous phase are then oxidized by injecting ozone generated in-situ, transforming them into CO2 and H2O. The system has a treatment capacity of 42,800 m3/h.
With Dopeless® technology - a special coating that is applied automatically at Tenaris mills around the world – connections are supplied RunReady™ and there is no need for the application of running or storage compounds, simplifying handling and yard operations. The integration of the scrubber abatement system generates far lower VOC emissions during the manufacturing process, and builds on the environmental benefits Dopeless® technology offers by eliminating the need to apply dope, saving 10-20 liters of water normally used in cleaning each connection before being lowered into the well.

“This initiative is another step in the company’s commitment to foster a safer and cleaner workplace,” says Carolina Bengochea, Tenaris environment senior director. “Additionally, we are creating a portfolio of products and services with minimal environmental impact, both in their application and their production.”
As part of its strategy towards the energy transition, Tenaris has announced a medium-term plan to reduce its CO2 emissions intensity per ton of steel by 30% compared to its level in 2018 by 2030, considering scope 1, 2 and 3 emissions. Learn more about Tenaris’s environmental plan here.
