What is the purpose of a weld neck flange?
A weld neck flange is designed to provide a strong, leak proof connection between pipes, especially in high pressure and high temperature systems. Its long tapered hub allows for a smooth transition of stress from the flange to the pipe, reducing turbulence and minimizing the risk of fatigue or failure. These flanges are welded directly to the pipe, ensuring structural integrity and durability, making them ideal for critical piping applications.
What is the difference between weld neck and slip on flanges?
The main difference lies in their design and installation. Weld neck flanges have a long tapered hub and are butt welded to the pipe, providing superior strength and resistance to pressure and stress. Slip on flanges, on the other hand, are slipped over the pipe and then fillet welded, making them easier to install but less suitable for high pressure applications. Weld neck flanges offer better performance under extreme conditions.
What are common applications for weld neck flanges?
Weld neck flanges are commonly used in oil and gas, petrochemical, power plants, shipbuilding, and other industries where high pressure, high temperature, or corrosive conditions exist. They are ideal for pipelines carrying steam, water, oil, chemicals, and other critical fluids.
