DIN 2634 Flange Dimensions

A flange is a device that helps in connecting valves, pipes, tubes, and other equipment to create an efficient piping system. The Din 2634 Flange is a type of welding neck flange that can be produced with different chemical constituents. These flanges possess good strength and have excellent corrosion resistance properties across different applications. A Din 2634 Pn25 Flange has a working pressure of 25 bar and can be used at maximum temperature up to 140 degrees C. They can be produced in forged, plate, threaded, and screwed specifications. These flanges can be availed possessing a raised, flat, and ring-type face. The DIN 2634 PN25 Weld Neck flanges are designed with a long tapered hub that allows it to transfer tension from the pipeline. These flanges are butt-welded in place and can be seen in high pressure and temperature conditions. The flanges are recommended in applications where repeated bending is taking place.

The DIN 2634 Flange Dimensions vary between standard sizes of 15 NB to 1200 NB. The dimensions of these flanges are dependent on the applications where they are used across different systems. The forging, heat treatment, and machining can also influence the dimensions of the flange. The DIN 2634 PN25 Flange Standards are produced by following all the norms set by various international and national unions. These flanges have schedules that meet the similar schedule of a piping grade.
