Galvanized steel pipes are steel pipes that have been galvanized. This coating protects steel from corrosion, and it is often used in outdoor construction, such as fences and handrails, or some indoor plumbing. It can also be called galvanized iron pipe.
The process of galvanization was first discussed by scientists in the 1770s, nearly 60 years before it was finally introduced in the 1830s. French engineer Stanislaus Tranquille Modeste Sorel took out the first patent for the process in 1937, and began manufacturing it soon after. By the 1850s, Europe was producing galvanized steel out of manufacturing plants located around the continent. The United States followed shortly thereafter, opening its first plant in the 1870s.
After carrying out feasible tests on WXDIO passivation process,the results show that it′s reasonable and feasible to apply the WXDI passivation fluid and planned passivation process to the production of galvanized steel pipes. In this way, we can obtain good corrosion resisting property and synthetic property to create good techmological and economical effects.
