Long Neck Flanges are designed for enhanced performance in high-pressure systems, ensuring strengthened connections between pipes and equipment. Their extended neck provides an additional layer of reinforcement, which significantly improves joint strength and reliability in fluctuating pressure and temperature scenarios. With reduced welding stress due to the distance of the weld from the flange face, these flanges minimize heat-affected zones, reducing the risk of weld distortion. Moreover, the smooth transition from the pipe to the flange neck helps improve fluid dynamics by lowering turbulence and pressure drops, thus enhancing overall system efficiency. Their versatility allows them to be used in various industrial applications, easily accommodating different pipe sizes and pressure ratings. Long Neck Flanges are manufactured in compliance with esteemed standards, enabling them to handle diverse materials including stainless steel, carbon steel, duplex steel, and specialized alloys, making them suitable for various operational environments.

Advantages of Long Neck Joint Flange

  • Enhanced Strength: The longer neck provides additional reinforcement to the pipe joint, improving its strength and resistance to pressure and temperature fluctuations.
  • Reduced Welding Stress: The extended length of the neck reduces the proximity of the weld to the flange face, minimizing heat-affected zones and weld distortion during welding.
  • Improved Flow Characteristics: The smooth transition between the pipe and the flange neck reduces flow turbulence and pressure drop, improving overall system efficiency.
  • Versatility: Long neck weld flanges can accommodate a wide range of pipe sizes and pressure ratings, making them suitable for various industrial applications.
