Info Tecnica
Que son DN, NPS y Schedule?
DN
Diametro Nominal
DN es la designacion metrica de tamano de tubo segun ISO 6708.
NPS
Nominal Pipe Size
NPS es la designacion imperial en Norteamerica.
SCH
Pipe Schedule
El numero de schedule determina el espesor. De SCH 5 a SCH 160.
Notas Importantes
- 1.STD = SCH 40 (hasta DN 250). Mayor: 9.53 mm fijo.
- 2.XS = SCH 80 (hasta DN 200). Mayor: 12.70 mm fijo.
- 3.XXS: tubo estandar mas pesado. No definido desde DN 350.
- 4.OD es constante para todos los schedules.
Calculo
Formula Peso Tubo
W = (OD - WT) x WT x 0.02466
W = Peso (kg/m), OD = Diam. Ext. (mm), WT = Esp. Pared (mm)
Ejemplo:
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
