PIASTRE TUBIERE
Diametro: fino a 2.500 mm
Spessore: fino a 1.000 mm
Peso: fino a 25 ton
Negli scambiatori di calore vengono utilizzate le Piastre Tubiere che possono essere fisse e flottanti.
Le piastre tubiere devono sopportare i carichi derivanti dalle pressioni esercitate dai due fluidi e dalle differenze di temperatura degli stessi.
