New liner technology offers up to 50 percent cost savings

May 2, 2011

The joint development of a lining solution by Evonik Industries (Essen, Germany) and Swagelining Limited (Glasgow, UK) is still in its infancy—but its potential is huge. Instead of the corrosion resistant alloy pipes currently used for many offshore oil production flowlines, the two companies are now developing a completely different concept: a combination of established liner technology from Swagelining and the custom-tailored VESTAMID® polyamide 12 from Evonik. This technology, based on the well proven concept of PE lining, which has been used successfully for many years to protect water-injection lines worldwide, is now being developed for hydrocarbon service to 100 degrees c.

Compared to corrosion resistant alloy pipes currently used for hydrocarbon transportation, carbon steel pipes offer significant cost-benefits and are far more readily available but are also far more susceptible to corrosion from aggressive products. Carbon steel pipes with liners constructed of VESTAMID®, on the other hand, are protected against internal corrosion and also offer an enormous weight and price advantage.

In the current project phase of development, VESTAMID® is being integrated with Swagelining’s proven liner installation technology to provide a close fitting fully protected pipeline system. Operators of subsea pipelines are invited to contact us for further information on this project.

With VESTAMID®, Evonik is the worldwide leading producer of polyamide 12 for flexible pipes for subsea oil production.
