Stainless steel flanges are widely used for secure and leak-proof pipe connections in industrial piping systems. Manufactured with precision machining and a smooth polished stainless steel finish, these flanges are designed for welding directly to pipes, ensuring high strength, accurate alignment, and long-term reliability under pressure and temperature variations.

The non-threaded welded connection provides excellent structural integrity, making these flanges suitable for high-pressure, high-temperature, and critical service applications where strength, cleanliness, and durability are essential.

Product Overview

Our stainless steel flanges are available in multiple designs to suit various piping layouts and industrial requirements. The smooth bore and accurately drilled bolt holes ensure easy installation, proper sealing, and reliable performance.

Manufactured from premium stainless steel grades, these flanges offer excellent corrosion resistance, mechanical strength, and extended service life in demanding environments.
