Flanges
Stellanox Steel is a trusted manufacturer and global supplier of high-performance Industrial Flanges crafted from premium materials including Stainless Steel, Alloy Steel, Carbon Steel, Nickel Alloys, Inconel, Monel, Hastelloy, Titanium, and Copper Alloys. Our flanges are designed for leak-proof, high-pressure, and high-temperature piping systems in sectors such as oil & gas, petrochemical, chemical processing, marine, aerospace, energy, and water treatment.
Available in standard and customized designs, our flanges conform to ASME, ANSI, DIN, EN, BS, and ISO standards.
What are Flanges?
Flanges are mechanical components used to connect pipes, valves, pumps, and other equipment to form a piping system. They provide easy access for cleaning, inspection, or modification and are critical for sealing and supporting fluid flow under high pressure or corrosive environments.
Depending on the system’s operating conditions, flanges are selected by material grade, pressure class, face type, and connection type.
