A PN25 DN150 flat flange refers to a specific type of flange used in piping systems. Let's break down its meaning:

  1. PN25: PN stands for "Pressure Nominal" and is a designation that indicates the pressure rating of the flange. In this case, PN25 means that the flange is designed to handle a maximum pressure of 25 bar or 362.6 psi.

  2. DN150: DN stands for "Diameter Nominal" and represents the nominal size or the inner diameter of the flange. In this case, DN150 indicates that the flange has a nominal size or inner diameter of 150 millimeters.

  3. Flat flange: A flat flange, also known as a blind flange, does not have an opening or a bore in the center. It is used to terminate or close off the end of a piping system when a future connection is not required. Flat flanges are typically used at the end of pipelines, pressure vessels, or equipment where a seal is required to block off a closed system.

The PN25 DN150 flat flange is designed to handle high-pressure applications up to 25 bar and has an inner diameter of 150 millimeters. It is used to close off the end of a piping system, providing a solid seal to prevent leaks or to block off the flow of fluids or gases. These flanges are commonly used in industries such as oil and gas, petrochemical, power generation, and water treatment.
