About Borusan Mannesmann
Borusan Mannesmann has over 60 years of experience providing high added value products to a range of industries including energy and water transportation, construction, and engineering. The company produces both large and small pipe diameter solutions to meet customer requirements.
Thanks to the high quality of its pipes, Borusan Mannesmann is the only Turkish manufacturer of spiral pipes authorised to supply the North American oil and gas pipeline market.
ArcelorMittal and Borusan Mannesmann work closely to realise high-spec pipeline project
The global oil and gas industry places some of the most stringent requirements on steel to ensure the long-term safety and security of energy networks. Nowhere are these requirements higher than in the United States. That’s why Borusan Mannesmann, a leading supplier to the industry, turned to ArcelorMittal Europe – Flat Products when they required steel for a new pipeline project in Texas. The 1.75 billion USD project will transport up to 56 million cubic metres (1.98 billion cubic feet) of natural gas daily from the Texas oilfields to the Atlantic coast.
Strict limits and parameters met
The project called for a high-quality steel grade commonly used in the oil and gas industry, API 5L X70 PSL 2. However, the end customer requested specific changes to the steel’s chemistry to improve weldability onsite. Strict limits were also placed on the mechanical and chemical properties of the steel, and new test requirements were specified to ensure these parameters were met.
“It was one of the most stringent steel specifications we have ever received for our large diameter pipes,” says Zafer Atabey, general manager of Borusan Mannesmann. “Thanks to its expertise and strong knowhow in steel, ArcelorMittal has been always a reliable partner in our oil and gas projects, so we naturally turned to them.”
Following the steel, every step of the way
Due to the high technical specifications for the steel, the Borusan Mannesmann team were allowed to follow the production of the steel at ArcelorMittal Bremen, Germany. “ArcelorMittal’s technical team played a significant role in ensuring the quality of the steel, and they did that with great transparency and effort,” says Zafer Atabey. “Our feedback was received very positively and triggered technical cooperation and synergies between Borusan Mannesmann and ArcelorMittal. This ensured that the production and delivery of the steel concluded on time, and with required level of quality.”
Once the steel was produced, it was shipped to the Borusan Mannesmann plant at Gemlik in Turkey. There, the 15.24 mm thick steel was formed into 42’’ spirally welded pipes in one of the world’s most advanced production lines for this type of oil and gas pipe. The pipes were then coated internally and externally to the project’s high standards before being delivered to the port of Corpus Christi in the United States.
Strong and trustworthy partnership
Despite the imposition of tariffs on steel by the United States government, the contract with Borusan went ahead due to the pipeline’s strategic importance. “There is a distinct lack of local suppliers who could meet the timeline given the quality constraints and the quantity of pipes required,” says Zafer Atabey. “The project owner decided to move forward with Borusan Mannesmann, whatever the conditions.”
For Zafer Atabey, the success of this project is likely to result in further cooperation between ArcelorMittal and Borusan Mannesmann: “Working with a strong and trustworthy supplier such as ArcelorMittal is crucial because of their excellence in terms of timing and quality. ArcelorMittal met our expectations perfectly throughout the project and we will continue that success by cooperating on upcoming projects.”
