What are the uses of galvanized steel pipes?

1. Anti-corrosion: The zinc layer of galvanized steel pipes can effectively prevent the steel pipes from contacting the external environment and prevent the occurrence of oxidative corrosion. Therefore, galvanized steel pipes are often used in construction projects, pipeline projects, bridge construction and other occasions that require long-term resistance to external environmental erosion.

2. Water supply and fluid transportation: Due to the good corrosion resistance of galvanized steel pipes, they are widely used in the fields of water supply and fluid transportation. Galvanized steel pipes can be used in urban water supply pipelines, industrial water pipelines, and transportation of oil, natural gas, chemical liquids and other fields.

3. Structural support: The strength and durability of galvanized steel pipes make them an ideal material for building structural support. It is often used in columns, beams, frames and other parts of buildings to provide stable structural support.

4. Furniture manufacturing: Galvanized steel pipes are also widely used in the furniture manufacturing industry. Because of its smooth and durable surface, it is an ideal choice for making furniture frames and support structures.

The operating temperature range of steel depends on its material and treatment method. For general hot-dip galvanized steel pipes, the operating temperature is generally between -40℃ and 200℃. In extremely cold environments below -40℃, the toughness of galvanized steel pipes will decrease and brittle fracture may occur. In high temperature environments, the zinc layer may melt or sinter, affecting the performance of the steel pipe.

However, for some special occasions, galvanized steel pipes of special materials can also be selected to meet higher or lower operating temperature requirements. For example, alloy steel or stainless steel galvanized steel pipes can be used at higher temperatures, while low-temperature steel galvanized steel pipes are suitable for use in extremely cold environments.
