“PN” stands for the French term Pression Nominal which means pressure nominal. The PN number is indicated by the term PN followed by a designation number. For example, PN 10, PN 50, etc. The value that follows the term PN indicates the approximate pressure rating in bars.

PN 10: This rating is common for water and air supply lines, as well as for medium-pressure applications like steam lines and compressed air systems. 3. PN 16: This category is often used for higher-pressure applications such as industrial process lines, water supply systems, and HVAC (heating, ventilation, and air conditioning) systems. 4.

PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric flange dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements.

Piping Class Ratings based on the ASME B16.5 - Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard - class and the corresponding ISO 7005 PN (Pression Nominal *) ratings: * "Pression Nominal" is the French equivalent of Pressure Nominal.

1、管道规格DN50就是 公称直径 50mm， PN10 就是 公称压力 10MPa。 2、公称直径 (nominal diameter)，又称平均外径 (mean outside diameter)。 指标准化以后的标准直径，以DN表示，单位mm。 例如内径1200mm的容器的公称直径标记为DN1200。

Key Differences Between PN 10 flange and PN16 Flanges: PN10: Designed for a maximum pressure of 10 bars (approximately 145 psi). Suitable for lower pressure applications like water lines, compressed air systems, and low-pressure heating systems. PN16: Can handle higher pressures up to 16 bars (approximately 232 psi).

2024年8月15日 · 压力容器的“ PN10”表示什么？ PN10代表的是公称压力等级，它不是实际的压力值。 在压力单位的表示中，"PN10"中的"PN"表示公称压力，而"10"通常指的是公称压力等级所对应的压力值的一

What is a PN flange? PN stands for “Pressure Nominale”. The numerical value written after PN specifies the flange’s Max. applicable pressure in bar, at a reference temperature of 20 °C. For e.g., the cold working pressure of PN10 flanges roughly …

The standards developed by DIN lays down both general or detailed specifications for products such as flanges, in addition to procedures and services. PN is often accompanied by the term DIN, which is an acronym for Pressure Nominale. Manufacturer of DIN Standard Flanges, Check DIN PN10 Flanges Standards and Weight
