Long Weld Neck Flange
A Long weld neck flange is a kind of flange connection that is connected to the long diameter of the pipe. It consists of a flange cover, flange ring, bolts, gaskets, etc. Long weld neck flanges are widely used in chemical, petroleum, natural gas, pharmaceutical, food, and other industries due to their characteristics of high pressure, high temperature, and good corrosion performance. Especially in the chemical and petroleum industries, long neck flanges are widely used in the manufacture of pressure vessels, heat exchangers, reactors, and other equipment.

Long Weld Neck Flange Models
Long Weld Neck Flange Appearance
The most prominent feature of a long weld neck flange is its elongated neck or extension, which extends from the main body of the flange. This neck is significantly longer than that of a standard weld neck flange, providing additional reinforcement and space for insulation or thermal protection.
The neck of a flange long welding neck typically exhibits a gradual taper from the base to the tip. This tapered design helps to distribute stress evenly along the length of the neck, reducing the risk of stress concentrations and enhancing the overall strength of the flange-neck junction.
Long neck flanges feature a raised face around the bore hole. The raised face provides a flat mating surface for gaskets, ensuring a secure and leak-proof seal when the flange is attached to another flange using bolts or component.

Long Weld Neck Flange Manufacturers
Advanced Science And Technology
All of our long weld neck flanges are forged. Forged long weld neck flanges offer several advantages over other types of flanges due to their superior strength, reliability, and durability. Being forged from a single piece of metal under high pressure and temperature, these flanges exhibit excellent mechanical properties and resistance to deformation, making them ideal for high-pressure and high-temperature piping systems.
Additionally, the forging process allows for precise control over the flange’s dimensions and surface finish, resulting in tight tolerances and smooth sealing surfaces, which are crucial for leak-proof connections in critical applications. Overall, the combination of strength, reliability, and precision make forged long weld neck flanges a preferred choice for demanding industrial environments where safety and performance are paramount;
