Feuerverzinkung Schicht dick, gleichm\u00e4\u00dfige Beschichtung, starke Haftung, lange Lebensdauer. Galvanische Kosten ist niedrig, die Oberfl\u00e4che ist nicht glatt, Korrosionsbest\u00e4ndigkeit als feuerverzinkte Rohr ist schlecht.<br>Feuerverzinktes Stahlrohr: Feuerverzinktes Stahlrohr, Stahlrohrsubstrat und geschmolzene Beschichtungsl\u00f6sung bilden durch physikalische und chemische Reaktion eine dichte Zink-Eisen-Legierungsschicht mit korrosionsbest\u00e4ndiger Struktur. Die Legierungsschicht ist mit der reinen Zinkschicht und dem Stahlrohrsubstrat verbunden. Daher ist die Korrosionsbest\u00e4ndigkeit sehr hoch.<br>Verzinkte Stahlrohre: Die Zinkschicht des kaltverzinkten Stahlrohrs ist eine elektrische Beschichtung, und die Zinkschicht ist vom Stahlrohrsubstrat getrennt. Die Zinkschicht ist sehr d\u00fcnn, und die Zinkschicht ist einfach auf dem Stahlrohrsubstrat befestigt, das leicht abfallen kann. Infolgedessen ist die Korrosionsbest\u00e4ndigkeit gering. In neuen H\u00e4usern ist die Verwendung von kaltverzinkten Stahlrohren f\u00fcr die Wasserversorgung verboten.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"400\" height=\"286\" src=\"https:\/\/www.wldsteel.com\/wp-content\/uploads\/2022\/11\/OIP-C-3.jpg\" alt=\"\" class=\"wp-image-4097\" srcset=\"https:\/\/www.wldsteel.com\/wp-content\/uploads\/2022\/11\/OIP-C-3.jpg 400w, https:\/\/www.wldsteel.com\/wp-content\/uploads\/2022\/11\/OIP-C-3-300x215.jpg 300w, https:\/\/www.wldsteel.com\/wp-content\/uploads\/2022\/11\/OIP-C-3-260x185.jpg 260w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>Galvanized pipe, also known as galvanized steel pipe, is divided into hot dip galvanized and electric galvanized.
