Whether you’re refurbishing an older nitric acid plant or fabricating the process equipment to be used in one, selecting the right stainless steel tubing can be critical. High-quality tube with low impurities and optimized corrosion resistance will not only reduce downtime and extend your plant lifetime, but will allow for better welding and bending during manufacturing. Explore our special range of high-performance tube for nitric acid plants – and put our materials knowledge to work!
Risk reducing tube for nitric acid services
Having supplied material for hundreds of urea and nitric acid plants over the past 60 years, we’ve learned a lot about optimizing cooler condensers and more.
Many producers tell us they want higher alloyed grades than traditional 304L to combat higher temperatures, corrosion or oxidation issues. At the same time, they don’t want to invest heavily in expensive reactive metals. And engineering companies need materials that allow for faster and easier fabrication. Regardless of your specific engineering needs, Alleima superior quality and material knowledge will offer you a competitive advantage – find out how!
