Leveraging Tenaris's expertise in metal-to-metal connections for extreme weather conditions, the design of THera™ Seal introduces an innovation that enables seamless integration between the vessel and the sealing system, eliminating the need for additional elastomeric seals, O-rings, or gaskets to maintain pressure integrity. This sealing solution provides robustness and versatility, guaranteeing exceptional gas sealability for high-pressure hydrogen applications.

"This new sealing system offers many benefits, including a simplified assembly process, extended lifespan, compatibility with hydrogen, and suitability for fast decompression rates. The development process of THera™ Seal spanned over two years and involved collaboration between multiple teams across Tenaris, including rigorous laboratory tests and on-field stress tests," explained Maurizio Bellingardi, senior product manager of hydrogen technology industrial applications.
