GNEE Low-Temperature Pressure Vessel Steel Applied in Key Overseas Projects​

Recently, the last sheet of 14mm-thick ASTM A537 Class 2 steel plate was successfully warehoused, marking the successful completion of the production task for this batch of low-temperature pressure vessel steel destined for a petrochemical storage tank project in Nigeria.​

The Nigerian petrochemical project is designed to use quenched and tempered high-strength steel (ASTM A537 Class 2) for the construction of propane storage tanks. This project requires a large quantity of steel and imposes extremely high demands on plate shape control and performance stability.

The GNEE team conducted multiple communications with the customer to provide feedback on technical requirements, and ultimately successfully entered the list of qualified steel suppliers for the project, with a total procurement volume of 3,156 tons.​

During the actual production process, the customer engaged DNV (Det Norske Veritas) and LRQA (Lloyd's Register Quality Assurance) as third-party entities to supervise the entire production and inspection process. GNEE made every effort to meet all supervision requirements from the customer and the third parties, and the final products obtained the customer's release approval on schedule. For the steel plates of 6-8mm specifications under the entire contract, both the comprehensive qualification rate of plate shape and the first-pass qualification rate of performance fully met the customer's requirements. More notably, the steel plates had sufficient strength margin: the impact energy of the quenched and tempered steel reached over 200J at -52℃, and the impact energy remained above 100J at -52℃ even in the simulated post-welding state. All performance indicators far exceeded expectations, providing a solid material guarantee for the safe implementation of the project.​

The customer stated that GNEE has demonstrated professional technical capabilities in the production control of low-temperature pressure vessel steel with extreme specifications, and the product performance has far surpassed the technical requirements, laying a solid foundation for the safe completion of the project. The customer expressed willingness to further deepen cooperation with GNEE in the future and look forward to achieving win-win results in more high-end steel application fields.​

The successful development of this type of steel plate not only fulfills the supply task for the Nigerian petrochemical pressure storage tank project but also, more importantly, accumulates valuable experience for material application in similar subsequent projects. This further enhances the market competitiveness of the enterprise's products and injects strong impetus into the sustainable development of the enterprise.​
