Large Diameter Flanges

Large Diameter Flanges

We are leading Stainless Steel Large Black and Bore Pipe Flange Manufacturer in India

Flanges are piping components that are designed in different sizes and shapes. Large Diameter Flanges are metal ring flanges that are manufactured to connect valves, pumps, and other piping equipment. Designed with sizes between 26 inches to 60 inches, they can be designed with different material specifications. The Large Diameter Stainless Steel Flanges are produced with at least 11% of chromium, giving the flanges enhanced corrosion resistance properties in difficult environments. Similarly, Large Diameter Carbon Steel Flanges are high-strength components that are available in different carbon grades. These flanges are susceptible to corrosion if they are not properly cared for. The Large Pipe Flange provides support to different piping equipment it is attached to during the vigorous movement of fluids and gases across stress-induced setups.

A Large Steel Flange comes in different diameters and sizes and can be used to transmit different types of media in the system. They have a simple installation process allowing them to securely fit in different applications due to their large sealing surface areas. They are generally seen in engineering units, food industries, oil and gas processing equipment, construction, power plants, etc. The Large Diameter Steel Flanges are resistant to abrasion and wear in the system when they are produced, making use of the best material. The manufacturing of these flanges usually takes place in tank-like equipment and a large-scale furnace is utilized in strengthening the module. The flange is generally bolted in place as a gasket is placed between the piping component and the flange to securely seal it in the system. A Large Split Flange can be easily installed on existing piping modules as it is made up of two interlocking pieces that securely join the module in place via the bolting process. The quality assured products can be delivered to your home within a short period.
