Nominal Pipe Size (NPS) je severoamerický soubor standardů používaných k označení průměru a tloušťky potrubí. Velikost potrubí je specifikována dvěma nedimenzionálními čísly: jmenovitá velikost potrubí (NPS) pro vnitřní průměr na základě palců a plán (Schéma nebo Sch.) Pro tloušťku stěny.
Získejte více informací o velikosti potrubí a tolerancích.
