For fluid transport requirements, we offer a broad portfolio of seamless pipe designed to meet the requirements of both the American National Standards Institute (ANSI) and American Society of Mechanical Engineers (AMSE). Our tube grades are certified, fully compliant and ready to go.
World-class quality, control and materials development
What sets us apart is our status as a fully integrated manufacturer, meaning we control of the entire manufacturing process from melt to final product. This ensures full traceability and exceptionally high-quality consistency from batch to batch. As a result, our materials not only meet the required standards but also maximize service life and ensures minimal downtime.
Wide range of in-stock options
Our stock program includes a wide range of seamless tube and pipe materials designed to resist severe operating conditions. The in-house ANSI/ASME seamless pipe program includes austenitic stainless steels, duplex and super-duplex stainless steels, as well as high-alloy austenitic stainless steel.
Innovative breakthroughs
Leveraging our metallurgical expertise and R&D, we continually achieve breakthroughs in stainless steel materials for the benefit of our customers. Every year, we add more specialized, high performance products to the program. We look forward to partnering with you to accelerate your business success with our materials know-how and world-class stainless steel pipes.
High priority on sustainability
At Alleima, sustainability is a top priority. We adhere to the UN Sustainability Goals (SDGs) and have set ambitious targets aligned with the Science Based Targets initiative (SBTi) to achieve zero emissions by 2050. In our manufacturing, we use 80% recycled material and utilize more than 96% fossil-free electricity across our sites.
