Top notch supplier of ASTM A182 Flange in more than 25 countries, Refer Price list of SS Pipe Flange

Stainless steel flanges manufacturer in India

A flange is a device that is employed to connect pipes, pumps, valves, and other equipment in the piping industry. Stainless Steel Flanges possess a protruded lip or rim that helps in providing strength and stability to different piping grade. The flanges provide an easy attachment detail and can be welded or bolted in place. The SS Flange has good corrosion resistance properties and work well in cryogenic as well as high pressure and temperature applications. A Stainless Steel Pipe Flange is employed to connect piping grades efficiently. These flanges are easy to access, allowing room for the inspection, modification, and repair. The Forged Stainless Steel Flanges are produced at extreme pressures giving them higher tensile and fatigue strength. These flanges have excellent surface porosity and possess a finer grain structure. Stainless Steel Forged Flanges are very reliable due to their uniform structure and composition. These flanges have enhanced wear resistance allowing them to withstand extreme conditions. We are the Stainless Steel Flanges manufacturer in India who produce quality-assured products utilizing the best raw materials and latest technology.

The ASTM A182 Flanges are forged and rolled alloy stainless steel grades that are very durable. These flanges are designed in threaded or welded configurations. ASTM SA182 Flange is a pressurized vessel grade that has different face types allowing them to securely seal the grade in place. The PN16 Stainless Steel Flanges are moderate pressure class flanges that showcase good working pressure. These flanges are quality-assured and can be customized to suit different requirements. A DN80 Stainless Steel Flange denotes the diameter nominal for the size of the pipe grade. These flanges have an inside diameter of 58.42mm with an outer diameter of 88.9m, and a wall thickness of 15.24mm. Our company is a SS Flange manufacturer who have good connections with logistical supply chains, thereby delivering products to your doorstep within a short period.
