Galvanized Steel pipe is a type of steel pipe that has undergone hot-dip galvanizing treatment. Hot dip galvanizing is the process of immersing steel pipes in molten zinc to form a zinc layer on their surface. This treatment can effectively prevent oxidation and corrosion of steel pipes, and extend their service life.
Galvanized steel pipes have the following characteristics:
1. Good anti-corrosion performance: The galvanized layer can effectively prevent steel pipes from oxidation and corrosion, enabling them to be used for a long time in humid and acidic environments.
2. Strong durability: Galvanized steel pipes have high durability and can withstand certain pressures and weights, making them suitable for various industrial and construction applications.
3. Smooth surface: The surface of galvanized steel pipes is smooth, not easy to accumulate dust and dirt, and easy to clean and maintain.
4. Easy installation: There are various connection methods for galvanized steel pipes, which can be installed and disassembled through welding, threaded connection, and other methods.
Galvanized steel pipes are widely used in industries such as construction, shipbuilding, chemical, power, and petroleum. In the field of architecture, it is commonly used in the construction of pipeline systems such as water pipes, heating pipes, and drainage pipes. In the industrial field, pipeline systems are commonly used to transport liquids, gases, and solid powders. In the field of petroleum, pipeline systems are commonly used to transport oil and natural gas.

In short, galvanized steel pipes have good anti-corrosion performance, durability, and easy installation, making them a commonly used pipeline material.

Galvanized round tubing is a kind of steel pipe with a circular cross-section. It is more durable than Carbon Steel tubes but more cost-effective than stainless tubes. Besides, round tubing has one continuous surface with no edges, which makes it more resistant to flexing and torsional twisting under weight and pressure. It is commonly used for transporting fluid, such as oil, water, gas, etc.
