Overview of Integral Flanges
Integral flanges, also known as long weld neck flanges, are a type of flange that is directly forged or machined as part of the pipe or fitting. This design eliminates the need for a separate weld, providing a stronger and more reliable connection. Integral flanges are widely used in high-pressure and high-temperature applications, where safety and performance are critical. At [abtersteel], we specialize in producing integral flanges that meet the highest industry standards, ensuring that your piping systems operate efficiently and safely.
Our integral flanges are available in a wide range of sizes, from 1/2″ to 80″ (DN10 to DN5000), and pressure ratings from 0.25 MPa to 250 MPa (150 Lb to 2500 Lb). This versatility makes them suitable for a variety of applications, from small-scale water conservancy projects to large-scale offshore oil platforms. We also offer a range of materials, including carbon steel, stainless steel, and alloy steel, to ensure compatibility with different media and environmental conditions.
