Also known as nozzle flanges or "long neck" flanges, our long weld neck flanges are meticulously designed to cater to the unique needs of pressure vessel and tank fabrication. Crafted as one-piece constructions, these flanges replace standard weld neck and pipe weld combinations, distinguishing themselves with the absence of a required weld connection.
Characterized by a straight thru bore with a square-cut end, the long weld neck flanges typically match the exact nominal pipe size, providing versatility for customization as needed. The base of the neck connecting to the flange is slightly radiused, minimizing the abrupt perpendicular connection and reinforcing the concept of a robust one-piece construction.
Long weld neck flanges are specialized pipe connectors with an extended neck, reducing stress and ensuring uniform fluid flow. Ideal for high-pressure applications in industries like petrochemicals, their design allows for easy welding and enhances structural integrity in critical piping connections.
A Long Weld Neck Flange is a type of flange that features an extended neck, allowing for a larger weld area and increased strength in the connection between the flange and the pipe.
Long Weld Neck Flanges are widely used in various industries, including oil and gas, chemical processing, power generation, and industrial manufacturing, where high-pressure and high-temperature conditions are common.
Long Weld Neck Flanges offer several advantages, such as increased strength, reduced stress concentrations, and improved fatigue resistance, making them suitable for critical applications with high-pressure and high-temperature requirements.
