Straight Long Weld Neck Flanges have an extended neck that is welded directly to the pipe, offering smooth fluid flow and minimal turbulence. They are ideal for high-pressure applications, especially in industries like power generation and petrochemicals, where structural integrity and leak-free performance are critical. The long neck also helps to reduce stress concentration at the base of the flange.
Heavy Barrel Long Weld Neck Flanges feature a thicker neck section compared to standard types, allowing them to withstand higher mechanical loads and internal pressures. These flanges are suited for demanding applications such as steam lines and reactor vessels, where strength and durability are paramount. The robust design ensures consistent performance in high-stress environments.
What is the function of a Long Weld Flange?
A Long Weld Flange is used in high-pressure piping systems to provide a strong and leak-proof connection, ensuring structural stability in demanding applications.
Where are Long Weld Flanges commonly used?
They are widely used in oil & gas, petrochemical, power plants, and marine industries due to their ability to withstand high temperatures and pressures.
What materials are used for Long Weld Flanges?
These flanges are manufactured using stainless steel, alloy steel, and carbon steel to provide superior strength, corrosion resistance, and longevity in industrial environments.
