Misure Dei Tubi E Delle Condotte
In ingegneria le tubazioni di dividono in:
- tubi (tubing),
- condotte (piping o pipe)
Questa suddivisione nasce nel mondo anglosassone, i tubi sono piccoli, generalmente massimo 25mm di diametro, mente le condotte sono piu' grandi.
Tubi (tubing)
I tubi nel mondo anglosassone si dividono a seconda del diametro esterno e sono espresse in pollici, la seguente tabella spiega quale sia il diametro effettivo:
| Denominazione | Diametro esterno in mm | Area di passaggio in mm2 |
|---|---|---|
| 1/16" | 1.588 | 1.98 |
| 1/8" | 3.175 | 7.91 |
| 1/4" | 6.350 | 31.65 |
| 3/8" | 9.525 | 71.22 |
| 1/2" | 12.700 | 126.61 |
| 5/8" | 15.875 | 197.83 |
| 3/4" | 19.050 | 284.88 |
| 7/8" | 22.225 | 387.75 |
| 1" | 25.400 | 506.45 |
Tubing BWG
A voler complicare una semplice denominazione esiste anche la specifica BWG (caldamente sconsigliata), che classifica le tubazioni secondo il Birmingham Wire Gauge:

Condotte misure in pollici (pipe)
Le condotte nel mondo anglosassone sono normalizzate attraverso una misura nominale e una schedula. Questi valori non sono molto espressivi delle misure effettive, ecco perche' ho redatto la seguente tabella:
