Galvanized tubes and fittings are components used in various applications, especially in construction, plumbing, and industrial settings. They are made from steel pipes and fittings that have been coated with a layer of zinc to protect them from corrosion and rust. The process of galvanization involves immersing the steel in a molten zinc bath or applying a zinc coating through electroplating.
Galvanized tubes and fittings are commonly used in outdoor or exposed environments where regular steel would be prone to rusting. The zinc coating acts as a sacrificial layer, corroding first before the underlying steel is affected, thereby extending the life of the components.
Sizes of Galvanized Tubes and Fittings:
Galvanized tubes and fittings come in a variety of sizes to suit different applications. The most common sizes of galvanized tubes are typically measured by their outer diameter (OD) and are expressed in inches or millimetres. Common sizes for galvanized tubes include:
1/2 inch (12.7 mm)
3/4 inch (19.05 mm)
1 inch (25.4 mm)
1-1/4 inch (31.75 mm)
1-1/2 inch (38.1 mm)
2 inches (50.8 mm)
And other larger diameters as needed for specific applications.
List of Materials Used:
The primary material used for galvanized tubes and fittings is steel. Different grades of steel may be utilized, such as mild steel or carbon steel. The steel is then coated with zinc using either of the following methods:
Hot-Dip Galvanizing: The steel is cleaned, dipped into a bath of molten zinc, and then cooled. This process results in a thick and durable zinc coating.
Electro-Galvanizing: This method involves applying a layer of zinc through an electroplating process. The coating is generally thinner than hot-dip galvanizing but still provides effective protection against corrosion.
Other materials that may be used in galvanized fittings include gaskets or seals made from materials like rubber or Teflon, which help ensure a watertight and secure connection.
It’s important to note that the availability of specific sizes and materials may vary depending on the manufacturer and regional standards. Therefore, it’s best to consult with suppliers or manufacturers to get precise information on the sizes and materials available for galvanized tubes and fittings.”
