Info Tecnica
Cosa sono DN, NPS e Schedule?
DN
Diametro Nominale
DN e la designazione metrica delle dimensioni tubo secondo ISO 6708.
NPS
Nominal Pipe Size
NPS e la designazione imperiale in Nord America.
SCH
Pipe Schedule
Il numero di schedule determina lo spessore. Da SCH 5 a SCH 160.
Note Importanti
- 1.STD = SCH 40 (fino a DN 250). Maggiore: 9.53 mm fisso.
- 2.XS = SCH 80 (fino a DN 200). Maggiore: 12.70 mm fisso.
- 3.XXS: tubo standard piu pesante. Non definito da DN 350.
- 4.OD e costante per tutti gli schedule.
Calcolo
Formula Peso Tubo
W = (OD - WT) x WT x 0.02466
W = Peso (kg/m), OD = Diam. Est. (mm), WT = Sp. Parete (mm)
Esempio:
DN100, SCH 40: OD = 114.3 mm, WT = 6.02 mm
W = (114.3 - 6.02) x 6.02 x 0.02466 = 16.07 kg/m
