Tubi Polietilene PFA 20 - PE 80 Tabella perdite di carico

Tabella di calcolo di perdite di carico su Tubi Polietilene PFA 20 - PE 80

Il termine PFA 16 sostituisce il termine PN 16

Entrambi indicano PFA = pressione di esercizio ammissibile: ca sua volta vuole indicare "Pressione idrostatica massima che un componente è in grado di sostenere durante l'esercizio".
