Summary	This standard specifies the steel pipe flanges (PN series) of the basic technical requirements, including the nominal size, nominal pressure, the material, the pressure temperature rating, flange type and size, sealing surfaces, tolerances and markings. This standard applies to nominal PN2. 5-PN160 steel pipe flanges and flanged lid, flange PN nominal pressure rating used that includes the following nine grades: PN2. 5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, PN160, nominal size and pipe diameter this standard applies to the pipe diameter, including a, B two series, A series of international standard series (commonly known as BSP), B series follows the series for the domestic (commonly known as the metric pipe), its nominal size DN and pipe diameter specified in Table 1. 0. 3, using B series steel flanges, should the value of nominal size DN mark after "B" to show the difference, but with the Series A pipe flange, do not have the value of nominal size DN mark after "A", see Chapter 13 of this standard, Chapter 14, this standard also applies to use as a connecting flange types of valves, pumps, chemical machinery, piping accessories and equipment Parts, this standard does not include special fluid conditions from material selection principles.
