WHAT ARE FLANGES?
Flanges are flat, circular components that possess uniform apertures at their centres. They are designed to establish connections, provide support, or seal the joints of pipes, valves, or other equipment within a piping system. These flanges are available in various shapes, such as raised face, flat face, and ring-type joint flanges. Typically, they are secured together using bolts and matching flanges to create a robust and waterproof connection.
The significance of flanges lies in their pivotal role in facilitating the assembly, disassembly, and maintenance of piping systems, all while ensuring their structural integrity and preventing any leakage under pressure or at connections. These indispensable components are commonly employed in industries such as oil and gas, chemical processing, and construction, where they serve as vital elements for transporting and containing fluids.

What Is flange?
Flanges exhibit diverse characteristics, with their distinct properties determined by the grade of stainless steel utilized. The manufacturing process of these flanges can either be forged or cast. Esteemed suppliers of stainless steel flanges furnish these components to reinforce or connect beams and columns in Piping Projects. Installing stainless steel pipe flanges is customized to the specific flange type, guaranteeing a precise and secure fit for seamless integration with the piping network.
The flanges manufacturer produces many flanges, each designed with unique properties and functionalities. Two plain stainless steel flanges can be securely fastened using bolts, with a gasket between them. Stainless steel pipe flanges are employed in pipelines that transport water and fuel. The gasket in the stainless pipe flanges seals any irregularities on the face, preventing any leakage of the service fluid from the flange joint. This sealing mechanism ensures a dependable and leak-free connection between the flanges, preserving the integrity of the piping system.

WHY CHOOSE Piping Projects India FLANGES?
Piping Projects India is a leading Flanges Supplier in Chennai, acknowledged for its provision of Flanges made from superior quality raw materials that satisfy the diverse requirements of our clientele. Purchasing Flanges from Piping Projects India offers numerous benefits, which include :
ARE CLASS 1500 AND 900 SS FLANGE ARE SAME?
The Class 1500 flange is specifically engineered to endure a greater pressure rating in comparison to the Class 900 flanges. Typically, Class 1500 flanges are designated for a pressure of 1500 pounds per square inch (psi), which is approximately equivalent to 103.4 bar. On the contrary, Class 900 flanges possess a lower pressure rating when compared to the Class 1500. They are generally rated for a pressure of 900 pounds per square inch (psi), which is approximately equivalent to 62.1 bar.
Difference between Steel Forged Flanges and Plate Flanges
Stainless Steel Forged Flanges are indispensable in establishing a secure and long-lasting connection between two machinery parts. Moreover, they can enhance the strength and stability of the overall structure by serving as extensions. In contrast, Stainless Steel Plate Flanges enable the reliable connection of one pipe to another through bolts, with a gasket placed in between to guarantee a dependable seal. These flanges find extensive application in fuel and water pipelines, where the absence of leaks is of utmost importance for fluid smooth and efficient transportation.
