DIN 2527 Flange

DIN 2527 Flange

We are Manufacturer of DIN 2527 PN6/ PN10 Blind Flange in India

DIN 2527 is a German standard that covers flanges from DIN 10 to DIN 1000 nominal sizes. The DIN 2527 Flange covers modules of a wide spectrum of sizes and pressure classes that are designed to work in different environments. The DIN 2527 PN6 Flange is a low-pressure rating of this flange. These flanges are designed to work in pressure ratings ranging from 6 bar. The DIN 2527 PN10 Flange has a slightly higher pressure rating of 10 bar. The material utilized in producing these flanges is thereby thickermaking the module stronger. A DIN 2527 PN16 Flange is designed to work in temperatures of 120 degrees C and possesses a pressure rating of 16 bar. This pressure rating is very common in the industry. The DIN 2527 PN16 Material can be custom designed in different shapes and sizes to meet different project requirements. The quality assured products are manufactured with the best raw materials and latest technology and are available across all our outlets.

Check Sizes and Dimensions of DIN 2527 PN16 Flanges

A DIN 2527 Blind Flange is designed without any face type or a boring center. These flanges are used to curtail the flow of fluids and gases in the system. The versatile flanges are bolted in place, allowing room for inspection and cleaning across harsh environments. The robust EN 1092-1 DIN 2527 BLRF Flange is designed with a raised surface area that is slightly above the bolting circle where the gasket is placed, creating a very strong sealing. The common flange type can be used in low as well as high pressure applications in the system.

EN 1092-1 DIN 2527 BLRF Flange available in 1 Bar to 400 Bar pressure rating
