Newly developed by the company

X60MO hot rolled coil pipeline steel for submarine pipelines

It has been successfully applied to a key project construction in the South China Sea

The first development and application of the product

Make remarkable achievements

mark

The company ranks among the first echelon of domestic submarine hot-rolled pipelines

peculiarity

The key order for X60MO pipeline steel for submarine pipelines is a product with a thickness of more than 14mm. The product has very strict requirements for strength indicators and low temperature toughness, and new CTOD performance requirements (CTOD performance is the first development and verification of the company's hot rolled products, and the development is extremely difficult). High-grade submarine pipeline steel has strict requirements for controlled rolling and cooling process, which is a test of process design and equipment support ability.
demand
According to the strict product technical requirements of customers, the science and technology quality center and the joint production plant have made a full design analysis, clarified the difficulties of the production process, and formulated strict guarantee measures. Using the high clean steel smelting technology, a lot of effective work has been done in the precise control of the composition, the control of the internal quality of the billet, the control of the edge defect of the billet, the control of the temperature uniformity of the whole coil, and so on, to achieve the stable control of quality.

Facing the actual situation of tight delivery time and heavy tasks, the production and marketing research team formulated practical plans, followed up the production inspection, grasped the existing problems in production in time, and formulated follow-up production guarantee measures to achieve stable control of various performance indicators and timely delivery. Technicians track the use of the user's products throughout the process, and after all use, the user has a high evaluation of the quality of the product.
