Weld Neck Flanges

Sunrise Industry is one of the largest manufacturers, suppliers, and exporters of Weld Neck Flanges in India. These flanges are ideal for applications involving high pressure, elevated or sub-zero temperatures, and critical conditions. Weld Neck Flanges feature a long tapered hub, which provides added reinforcement and reduces the risk of flange deformation under heavy load, making them suitable for severe service environments.

Our Weld Neck Flanges are available in a wide variety of materials, including Stainless Steel, Carbon Steel, Alloy Steel, Duplex & Super Duplex, Monel, Hastelloy, Alloy 20, and High Nickel Alloys. We also manufacture flanges that comply with ANSI B16.5, ANSI B16.47, and MSS SP-44 standards, serving diverse industries such as oil & gas, petrochemical, power generation, and marine.

We proudly export our high-performance Weld Neck Flanges to countries like Qatar, Saudi Arabia, Bahrain, UAE, Indonesia, United States, Singapore, Malaysia, Turkey, Russia, Ukraine, South Africa, and Australia. With a strong logistics network and strict quality control, Sunrise Industry ensures timely and reliable delivery to our global clients.
