In the steel industry, galvanized steel pipes are a steel pipe treated with galvanized treatment, also known as thermal galvanized steel pipe. The so -called galvanized galvanized refers to the surface of the steel pipe on the surface of the steel tube to protect the steel pipe from being influenced by oxidation and corrosion. Galvanized steel pipes are usually controlled by seamless steel pipes or welded steel. During the production process, the surface of the steel pipe is chemically reacts with the fusion zinc liquid to form a sturdy zinc layer.
What are the uses of galvanized steel pipes?
1. Anti -corrosion: The zinc layer of galvanized steel pipe can effectively prevent contact between steel pipes with the external environment and prevent oxidation and corrosion. Therefore, galvanized steel pipes are often used for construction engineering, pipeline engineering, and bridge construction.
2. Water supply and transportation fluid: Since the galvanized steel pipe has good corrosion resistance, it is widely used in the field of water supply and transportation. Galvanized steel pipes can be used in urban water supply pipelines, industrial water pipelines, and transportation of oil, natural gas, chemical liquid.
3. Structural support: The strength and durability of galvanized steel pipes make it an ideal material for building structural support. It is often used in the pillars, beams, frames and other parts of the building, which can provide stable structural support.
4. Furniture manufacturing: Galvanized steel pipes are also widely used in the furniture manufacturing industry. Due to its smooth and durable surface, it makes it an ideal choice for making furniture skeleton and support structure.
The use temperature range of galvanized steel pipes
The temperature range of the use of steel depends on its material and treatment. For ordinary hot-dip galvanized steel pipes, the use temperature is generally between -40 ° C and 200 ° C. In extremely cold environments below -40 ° C, the toughness of galvanized steel pipes will be reduced, and crispy breaks may occur. In high temperature environments, the zinc layer may melt or sinter, affecting the performance of the steel pipe.
However, for some special needs, you can also choose a galvanized steel pipe with special materials to meet higher or lower use 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.
To sum up, galvanized steel pipes are steel pipes that enhance their corrosion resistance by plating a zinc layer on the surface of the steel pipe. It has various purposes such as corrosion, water supply and transportation, structural support, and furniture manufacturing. However, the use temperature of galvanized steel pipes needs to be determined according to the specific material and treatment method. Generally speaking, between -40 ° C and 200 ° C. If you use it in a special environment, you need to choose a galvanized steel pipe with a special material to meet the requirements.
