Weld Neck Flanges


Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

We are a fast growing organization, engaged in manufacturing, supply and export of welding neck flanges, industrial weld neck flanges and forged flanges. Our weld neck flanges are drilled with the wall thickness of flange having the same dimensions of pipe. Flanges for heavier pipes have smaller bore, while flanges of lighter pipes have larger bore. These weld neck flanges, industrial weld neck flanges, forged flanges are normally used for high-pressure, cold or hot temperature.
