What are Carbon Steel Weld Neck Flanges?

Carbon Steel Weld Neck Flanges are flanges designed with a long tapered hub that gradually transfers stress from the flange to the pipe, reducing turbulence and improving flow characteristics. These flanges are butt welded directly to the pipe, providing excellent strength, superior pressure handling capability, and enhanced reliability.

Carbon Steel Weld Neck Flanges are widely used in critical applications involving high pressure, high temperature, cyclic loading, and severe operating environments.

At Maruti International, we manufacture premium-quality Raised Face Weld Neck Flanges, Flat Face Weld Neck Flanges, Ring Type Joint Weld Neck Flanges, Long Weld Neck Flanges, and customized carbon steel flanges in accordance with international standards.
