A long weld neck flange is a specialized flange used in piping systems to join pipes, valves, or equipment together. It is distinguishable by its elongated neck or hub, which serves to provide additional reinforcement and space for welding. The long weld neck flange (LWN) is similar to a standard welding neck flange but with a considerably longer neck. This particular type of flange is commonly employed as a nozzle for barrels or columns. In addition to the regular long weld neck flange, there are also long weld neck heavy barrels (HB) and equal LWN barrels (E), which possess a distinct shape and thicker wall construction.

Types Of Materials Used to Manufacture Long Weld Neck Flanges

Flanges are made up of various materials, but they depend on the environment and stress to which they are subjected.

• Carbon steel
• Alloy Steel
• Stainless steel
• Titanium
• Duplex & Super Duplex Steel
• Nickel alloy

Features of Long Weld Neck Flanges

• Flange Face: The flange face is the flat or raised surface on the front of the flange that comes into contact with the mating flange or equipment. It provides a sealing surface.
• Neck or Hub: The neck or hub of a long weld neck flange is the elongated section connecting the flange face to the pipe. It extends the distance between the pipe and the flange face, allowing for easy alignment and access for welding.
• Tapered Neck: The neck of a long weld neck flange is tapered, meaning it has a gradually decreasing thickness along its length. This design helps reduce stress concentration and provides additional strength to withstand high-pressure and high-temperature applications.
• Welding End: The end of the long weld neck flange is beveled to facilitate proper welding between the flange and the pipe. It allows for a full penetration weld, ensuring a strong and leak-free connection.

Benefits of Long Weld Neck Flanges

• Strength and Durability: The extended neck provides added structural support, making Long Weld Neck Flanges suitable for high-pressure and high-temperature applications.
• Weldability: The long neck allows for easier access during welding, ensuring proper penetration and a strong joint between the flange and the pipe.
• Alignment: The extended neck helps with alignment between pipes and equipment, simplifying the installation process.
• Flow Characteristics: The smooth transition from the pipe to the flange face minimizes turbulence and pressure drop, improving the flow characteristics within the piping system.

Application of Long Weld-Neck-Flanges

Long weld neck flanges are widely used in various industries and applications where reliable and robust connections are required. Some of the key applications of long weld neck flanges include:

• High-Pressure Systems
• High-Temperature Environments
• Petrochemical Industry
• Oil and Gas Sector
• Process Piping
• Shipbuilding and Marine Industry
• Power Generation and so on
