They specialize in providing strong, high-quality solutions for isolating and maintaining pipelines. These flanges boast a clever dual-disc design—one solid and the other with a hole—connected by a bridge, which makes it easy to manage flow or isolate sections in critical piping systems. Crafted from premium Inconel alloys, they deliver outstanding resistance to corrosion, oxidation, and high temperatures. Quan Flanges and Plates caters to various industries, including oil and gas, petrochemical, chemical processing, marine, and power generation, offering reliable and precisely engineered spectacle flange solutions.
Inconel Spectacle Flanges are primarily made up of nickel (50–55%), chromium (17–21%), iron (the balance), along with niobium (4.75–5.5%), molybdenum (2.8–3.3%), titanium (0.65–1.15%), and aluminum (0.2–0.8%). This unique composition guarantees exceptional resistance to corrosion, oxidation, and high-temperature environments. On the mechanical side, they showcase a tensile strength of 1,240–1,380 MPa, yield strength of 1,030–1,100 MPa, and an elongation of 12–20%. Their toughness, fatigue resistance, and thermal stability make them ideal for extreme service conditions and critical applications.
