MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202441102573 A) filed by Gudlyf Mobility Pvt Ltd on December 24, 2024, for Metal End Connector For High-Pressure Gas Storage Vessels And Its Thermal Treatment Process.
Inventors include Ajeet Babu Kumar Parasumanna; and Kumar P S.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a manufacturing method for forming a leak-proof polymer–metal liner assembly for gas storage applications. A precision-forged metal end boss having circumferential grooves and undercuts is positioned within a mould and integrated with a polymer liner using a rotational moulding process. Thermoplastic powder is melted and allowed to flow into the anchoring features of the boss, and upon cooling, differential thermal contraction generates compressive stresses that create a self-locking, gas-tight joint. The process eliminates welding, adhesives, and mechanical fasteners while ensuring structural integrity and leakage resistance. The resulting liner–boss assembly demonstrates reliable performance under hydraulic and helium leak testing and is suitable for low-pressure gas storage applications including hydrogen, CNG, fire suppression, and industrial gas containers.
