Specialized DIN Flange Standard Manufacturer, DIN Flange Dimensions in MM, DIN Flange Pressure Ratings

Marcel Piping Projects Supply PVT LTD is well-known manufacturers of DIN Flanges in India. Although DIN standard flanges now have been superseded by EN 1092-1, it is still commonly used in project practice. DIN series flanges cover an extensive range of pressure ratings from 1 bar(PN 1) to 400 bar(PN 400): 1 bar, 2.5 bar, 6 bar, 10 bar, 16 bar, 25 bar, 40 bar, 64 bar, 100 bar, 160 bar, 250 bar, 320 bar, 400 bar. According to SI unit system, 1 bar = 100 kPa = 0.1 MPa = 14.5 psi. Usually, DIN standard flanges are categorized as:
