Q235 Hot-Dipped Galvanized Steel Pipe
What is hot-dip galvanized pipe?
Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The steel pipe matrix undergoes complex physical and chemical reactions with the molten plating bath to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance.
Q235 galvanized steel pipe is indeed a widely used ordinary carbon structural steel. This steel is divided into different types according to quality grade, Q235A, Q235B, Q235C and Q235D. These different grades are mainly divided based on the chemical composition, mechanical properties and process properties of the steel.

Steel galvanized piping
1. Uniformity of the galvanized layer: The steel pipe sample shall not turn red (copper color) when immersed in copper sulfate solution for 5 consecutive times.
2. Surface quality: The surface of galvanized steel pipes should have a complete galvanized layer. There should be no uncoated black spots and bubbles. Small rough surfaces and local zinc tumors are allowed.
3. Galvanized layer weight: According to the requirements of the purchaser, galvanized steel pipes can be measured for zinc layer weight. The average value should not be less than 500g/square meter, and any sample should not be less than 480g/square meter.
