The DIN 2527 Flanges with the specifications of this standard could be used at a working pressure of up to 16 bars and a maximum temperature of 120°C. It should be considered that the material's or the din 2527 pn6 flange's yield point will decrease at higher temperatures between 120°C and 300°C.
The standard is identified as DIN 2527 in the din 2527 flange dimensions pdf. The materials indicated in the standard, in addition to the din 2527 pn40 flange specifications, are both carbon steel and stainless steel. The blind flanges specified in DIN 2527 are made from these materials. Either forged or cast steel grades are used to make the flange din 2527 pn16.
The size chart for the ASME B16.5 standard flange, which ranges in size from 12 inch (15 NB) to 48 inch (1200 NB) or DN10DN5000, is also included in the din 2527 pn10 flange dimensions. The surface treatment of the flange din 2527 pn10 is significant. The flange din 2527 pn16 is often surface-treated by either treating the flange with zinc using various techniques. For instance, using either cold or hot dip galvanization, a thick layer of zinc can be applied to the blind
The din 2527 pn16 blind flange surface can be electroplated to add a thin zinc covering. The din 2527 pn10 flange may also be coated with Oil Black Paint, Anti-rust Paint, or Yellow Transparent. The din 2527 pn10 flange's work service life is extended and its corrosion resistance is improved by coating or surface treating it.
Most manufacturers or producers of DIN 2527 Pipe Flanges are able to provide Test Certificates, EN 10204/3.1B, 100% Radiography Test Report, Raw Materials Certificate, Third Party Inspection Report, etc.
