Arctic Directory: Duoline GRE lined tubing a proven alternative

Duoline Technologies said April 24 that its glass-reinforced-epoxy or GRE lined tubing has proven to be an alternative to corrosion resistant alloys. Since 1964, more than 80 million feet of Duoline GRE lined tubing has been successfully installed worldwide, the company said.

However, with more customers moving into deepwater drilling, which is a very harsh and corrosive environment, the industry requires different kinds of product-based solutions, Duoline said.

For GRE to succeed in deepwater, the use of unmodified premium connections was key and testing had not been done. GRE has subsequently been tested and qualifies as a cost-effective alternative to CRA tubing. On a project scope the cost savings is significant, thus GRE is now used in many deepwater projects for a variety of operators. For more information visit www.duoline.com.
