Russia’s leading pipe maker United Metallurgical Company has shipped over 3 thousand tonnes of pipes with a three-layer anti-corrosion coating for the construction of a pipeline under the West Qurna-2 project in Iraq. The pipes were manufactured at the Vyksa plant of OMK in Nizhny Novgorod Region from flat rolled products of its own production in a short time and in compliance with strict quality criteria.
Specialists of the engineering and technological center of the enterprise have developed a special chemical composition of steel and a technology for thermomechanical rolling of sheets of strength group X60MS (operation in acidic environments) according to API Spec 5L. As a result, rolled products of a homogeneous structure with a high level of toughness, cold resistance and strength characteristics in combination with resistance to hydrogen and sulfide stress corrosion cracking were obtained. To fulfill the requirements of the order for corrosion resistance in the welded joint, the modes of submerged arc welding were developed and mastered. These measures are of particular importance since the West Qurna-2 field is located in a swampy area and the oil has high hydrogen sulfide content.
In addition, for this order, specialists from the Vyksa plant of OMK in a short time developed and mastered a new technology for the production of polypropylene coating for pipes according to the requirements of the project. All manufactured pipes have an increased service life and are designed for use in hot climates and acidic environments. Additionally, to protect against atmospheric corrosion, all pipe ends were coated with an environmentally friendly preservative.
The West Qurna-2 field, located in southern Iraq, is one of the largest in the world. Initial recoverable oil reserves are about 14 billion barrels. In 2009, a consortium of PJSC LUKOIL and the Norwegian company Statoil won the tender for the right to develop the West Qurna-2 field. In 2014, commercial oil production began at the field. In 2019, PJSC LUKOIL started drilling new production wells at the West Qurna-2 field as part of the second stage of development.
