With the rapid exhaustion of existing fields, the Oil & Gas industry faces new industrial challenges to meet the requirements of more demanding environments, e.g. ultra-deep offshore, arctic well-below-zero conditions, or more aggressive gas. This results in the need for products withstanding higher pressure, very high (or very low) temperatures, and fierce corrosion, which Aubert & Duval is able to provide.
Oil & Gas
A long history
Due to its dedicated forging and heat-treatment equipment for extra-long steel parts, Aubert & Duval has been a leading supplier in the market of specialty joints for TLP, Spar and FPSO. Some of our products have been operational under extremely severe conditions for 20 years. We have contributed to projects such as Girasol, Brutus, Bonga, Matterhorn, Constitution and many more.
Focusing on quality
Aubert & Duval follows the most stringent requirements in terms of grade composition, microstructural material integrity, dimensional tolerances and quality control. All of our products comply with ASTM and NACE standards.
Aubert & Duval’s offering
To meet specific requests for critical parts in the Oil & Gas industries, Aubert & Duval has built an extensive product offering. It provides the optimum combination of expected functionalities including corrosion and low temperature resistance, shock and fatigue resistance, durability and performance.
Aubert & Duval facilities have a range of high-tech equipment dedicated to the manufacture of finished forged parts, up to 20 m (66 ft) long:
- Steel Melting: 60 MT Electric Arc Furnace able to provide parts up to 30 MT for massive forgings and 12 MT for tubes
- Forging: 4,500 MT open die forging press
- Heat Treatment: 14 horizontal or vertical furnaces up to 21m, quenching, cold or warm straightening
- Machining: turning, milling, drilling, sawing, etc.
These machines are typically optimized for long specialty riser joints.
