Stainless Steel Long Weld Neck Flanges Manufacture, Suppliers & Exporters in India - Suresh Steel Centre

Suresh Steel Centre is the leading Stainless Steel Long Weld Neck Flanges Manufacturer, Supplier, and Stockist in India. An integral self-reinforcing flange connection, long weld neck flanges are usually used for the ASME pressure vessel applications. The Long Weld Neck (LWN) Flange was designed to be utilised as a bolt up connection to the vessel in place of a Weld Neck Flange and piece of pipe. The neck's tension was reduced and shifted to the base, where it linked to the vessel, by this design.

The most popular self-reinforced nozzle design is the Long Weld Neck Flange. The thicker neck of the heavy barrel type nozzles is appropriate for applications that demand higher pressure and temperature. For pipes diameters 1/2 to 24 and 26 to 60, the flange end and sealing face are constructed in accordance with ASME B16.5 and B16.47, respectively. Overall, the neck length increases with increasing nominal size and pressure.
