What are the main functions of Q235 galvanized welded pipe?
The main functions of Q235 galvanized welded pipe are structural support, fluid transportation, and corrosion protection. It features high strength, good weldability, and corrosion resistance.
How does the galvanized layer protect the steel pipe?
The galvanized layer primarily protects the steel pipe through sacrificial anode protection. This means the zinc layer corrodes instead of the steel, while also blocking corrosive substances.
What is the commonly used galvanized layer thickness for Q235 galvanized welded pipe?
The commonly used galvanized layer thickness for Q235 welded pipe is: 35-650μm for hot-dip galvanized pipe and 5-15μm for cold-dip galvanized pipe. The specific thickness depends on the process and application.
What is the difference between hot-dip galvanizing and electro-galvanizing?
Hot-dip galvanizing involves immersing the steel in molten zinc to form a thick, durable, but rough-surfaced coating. Electro-galvanizing, on the other hand, uses an electrochemical process to form a thin, smooth, and more aesthetically pleasing zinc layer on the steel surface.
What are the main application areas of Q235 galvanized welded pipe?
Q235 galvanized welded pipes are mainly used in the construction industry, as well as in infrastructure such as utility poles and fences. They are also used in water supply and irrigation systems, agriculture, and general manufacturing industries such as machinery frames and components.
