Introduction and application of hot-dip galvanized channel steel
Hot-dip galvanized channel steel, also known as hot-dip zinc channel steel and hot-dip galvanized channel steel, is an effective way to prevent metal corrosion. It is to immerse the channel steel after rust removal into the melting zinc liquid about ~℃, so that the surface of the channel steel is attached to the zinc layer, so as to play the purpose of anti-corrosion.
1. Application of hot-dip galvanized channel steel
The application of hot-dip galvanized channel steel is also expanded with the development of industry and agriculture. Therefore, the hot-dip galvanized products produced by Tianjin Sizheng Iron and Steel are used in buildings (such as glass curtain walls, power towers, communication grids, water and gas transmission, wire bushings, scaffolding, houses, etc.), Bridges, and transportation; Industry (such as chemical equipment, petroleum processing, ocean exploration, metal structures, power transmission, shipbuilding, etc.); Agriculture (such as sprinkler irrigation, heating houses), etc., has been widely used in recent years. Because hot-dip galvanized products have beautiful appearance, good corrosion resistance and other characteristics, its application is more and more extensive.
2. Welded connection
If the pipe ends of galvanized steel pipes are not in a straight line and the pipes have a bew, it is recommended to cut off a small section of the pipe ends before processing.
After the joint of galvanized steel pipe, the joint of two pipes is not strict, resulting in uneven welding thickness; As well as the steel pipe due to its own reasons or transportation bump, resulting in the pipe mouth oval, it is recommended to cut off a small section of the pipe head before processing.
After the pipe orifice of the galvanized steel pipe is connected, sand holes appear at the pipe orifice.
Due to technical reasons during welding.
3. What is the material of hot-dip galvanized channel steel?
Domestic commonly used channel steel material is:
Hot dip galvanizing is a process of reprocessing in order to strengthen the corrosion resistance and oxidation resistance of raw materials. The material also depends on what the channel steel itself is made of. The general channel steel is mostly galvanized.
