Correct flange selection is vital for maintaining leak-free and safe operation under varying pressures and temperatures. The PN (Pressure Nominal) rating indicates the maximum allowable working pressure at 20 °C. Matching the right flange to the system’s design pressure prevents gasket failure and joint fatigue.
Standardized dimensions simplify maintenance and equipment integration. Using PN-rated flanges allows engineers to connect pumps, valves, and process lines from different manufacturers without compatibility issues. This consistency also supports global compliance with EN 1092-1 and ISO flange standards commonly used across the industry.
In hygienic and industrial environments, precise flange alignment reduces turbulence, energy loss, and wear on seals. Selecting appropriate bolt sizes and torque values ensures even compression and long-term durability. Stainless steel and coated flanges are often preferred in food processing for corrosion resistance and easy cleaning.
Accurate reference to PN flange dimensions helps engineers design robust and efficient systems. This table serves as a practical guide for selecting compatible components, ensuring secure connections, and maintaining reliability in fluid handling installations of all types.
