Detailed Information

DIN 2633 Welding Neck Flanges is circumferentially welded into the system. The flange is welded at its neck, which means that the integrity of the butt welded area could be easily examined by conducting a radiography test.  Since the bores of both pipe as well as the flange match, there is a reduction in turbulence and erosion inside the pipeline . Hence, the din 2633 weld neck flanges is therefore favoured in quite a few critical applications .

The weld neck of the flange allows for welding of the flange with pipes. This provides stronger connection at joints. Each flange type has a different advantage and each of them can come in different pressure capacities. The flanges range in size from DIN 10 through DIN 5000. The din 2633 pn16 flanges are some of the low pressure capable flanges where there are high pressure flanges are also available. The flange pressure rating varies from PN6 through PN64. The sizes can range from ½ inches to 48 inches in imperial scales and the pressure classes of the flanges norma din 2633 can range from class 150 through class 2500. The strength, physical properties, mechanical properties, dimensions and types of flanges along with the ease of welding all depend on the din 2633 flange material that is used to make the flanges. There are stainless steel, carbon steel, duplex steel and alloy steel flanges. There are high tensile strength, high pressure and high temperature demanding applications. The din 2633 flanges dimension has to be selected along with the flange material to suit the different needs of different applications. These flanges are used in oil and gas, offshore oil drilling, marine, sea water, food processing, power generation, heat exchanger and other types of industrial applications.
