Produktbeschreibung
ASTM A192/ASME SA192 Kohlenstoffstahl -Seamelnrohr für Kessel aufgetragen
ASTM A192 deckt für den Hochdruck-Service die minimale Dicke, einen nahtlosen Kohlenstoffstahlkessel und Überhitzerrohre ab.
Die Schlauchgrößen und Dicken, die normalerweise dieser Spezifikation geliefert werden, betragen 1/2 Zoll bis zu 12,7 bis 177,8 mm) Außendurchmesser und 0,085 bis 1,000 Zoll (2,2 bis 25,4 mm), einschließlich der Mindestwanddicke. Schläuche mit anderen Abmessungen können bereitgestellt werden, vorausgesetzt, solche Röhrchen entsprechen allen anderen Anforderungen dieser Spezifikation.
