20# steel flange PN10 DN80 refers to a specific type of flange used in piping systems. The following is an explanation of related terms:
- 20# Steel Flange**: This indicates the material and pressure rating of the flange. “20#” usually means that the flange is made of carbon steel and has a pressure rating of 20 kg/cm² (approximately 2.0 MPa or 290 psi) at room temperature.
- PN10: This is the nominal pressure value, indicating that the flange is designed to withstand a maximum pressure of 10 bar (approximately 145 psi). PN (nominal pressure value) is a European standard used to classify the pressure ratings of flanges and fittings.
- DN80: This refers to the nominal diameter of the flange, which is 80 millimeters. DN (nominal diameter) is a standard unit of measurement used to describe the size of pipes and fittings.
