What is Long Weld Neck Flanges?
Long weld neck flanges, or extended weld neck flanges, are specialized components used in pipeline systems to connect pipes, valves, and equipment. They have an extended neck or hub that extends beyond the main body of the flange. This lengthened neck has various advantages over regular weld neck flanges, making it ideal for certain applications.
Another noteworthy attribute of long weld neck flanges is their capacity to withstand larger bending moments. The longer neck provides increased resistance to bending forces, making it appropriate for applications involving large lateral forces or moments occurring on the flange. Furthermore, the extended neck provides a smoother transition from the flange to the pipe, lowering turbulence and pressure drop in the piping system.
Piping Projects India is a leading Long Weld Neck Flanges Manufacturer in India. This gives a wide range of alternatives, ensuring that customers have access to high-quality Long Weld Neck Flanges that may be tailored to their individual application needs. Long Weld Neck Flanges are available in a wide range of sizes and configurable choices, some of which are shown here.
