Asse delle X = spessore minimo delle pareti (mm)Asse delle Y = pressione di lavoro (bar) sul cls

PL = Pressione di lavoroDN = Diametro nominale

Esempio di lettura: Se PL = 70 bar DN = 125 mm

Tracciare una linea orizzontale (linea A) a quota 70 sull'asse delle Y fino ad incrociare la retta

DN 125.Dal punto di incrocio tracciare una linea verticale (linea B) fino ad incrociare l'asse delle X che

determina lo spessore minimo delle tubazioni = 2.9 (mm)

X-axis = walls minimum thicknessY-axis = operating pressures

PL = Operating PressuresDN = Major Diameter

Reading example: if PL = 70 bar DN = 125 mm

Mark an horizontal line (line A) at height 70 on Y-axis, up to cross the right line DN 125. From

crossing point, mark a vertical line (line B) up to cross the X-axis, which determines the pipingminimum thickness = 2.9 [mm].
