RED EARTH Steels Pvt. Ltd. manufacturer & exporter of Weld Neck Flanges availbale in various forms and size, standards like ASME B16.5 flanges, ASME B16.47 Flanges.We also offer custom-made Weld Neck flanges that have been widely appreciated by our clients.
A Weld Neck Flange is drilled with the wall thickness of the Flange having equal dimensions to the matching pipe. The lighter the pipe is the larger the bore is in the Weld Neck Flange. And conversely the heavier the pipe is the smaller the bore is in the Weld Neck Flange. Weld Neck Flanges are usually used in high pressure systems and are suitable for cold or hot temperatures.
