Flanges
Flanges are essential piping components designed to create strong, secure, and leak-tight connections between pipes, valves, pumps, pressure vessels, and other equipment in industrial piping systems. By using bolted connections with appropriate gaskets, flanges allow quick assembly, easy maintenance, and convenient system modifications without cutting or welding pipelines. Manufactured from high-quality materials such as carbon steel, stainless steel, alloy steel, and non-ferrous metals, flanges provide excellent mechanical strength, pressure resistance, and long service life. They are widely used in oil and gas, petrochemical, chemical processing, water treatment, power generation, marine engineering, HVAC, food and beverage production, pharmaceutical manufacturing, and general industrial applications.
Customers may also search for these products using the following names: pipe flanges, steel flanges, stainless steel flanges, carbon steel flanges, industrial flanges, welding neck flanges, slip-on flanges, blind flanges, socket weld flanges, threaded flanges, lap joint flanges, plate flanges, raised face flanges, RF flanges, RTJ flanges, PN flanges, ANSI flanges, ASME flanges, DIN flanges, EN 1092-1 flanges, pipe flange fittings, flanged pipe connections, and pipeline flanges.
Flanges are available in a wide range of sizes, pressure classes, facing types, materials, and international standards to meet the requirements of low-, medium-, and high-pressure piping systems. Their precision machining ensures accurate alignment, reliable sealing, and long-term performance, making them an essential component of modern industrial piping installations.
You can order these products from POLBERIS, where you will find a comprehensive selection of premium-quality flanges, industrial fittings, valves, pipes, and piping components at competitive prices.
