Galvanized steel pipes can be called galvanized pipes. There are four main differences between galvanized seamless steel pipes and galvanized steel pipes.

1. Different Uses
Galvanized seamless steel pipes are mainly used for general structures and mechanical structures. Ordinary galvanized steel pipes are welded pipes. They are generally used for the transportation of medium and low-pressure fluid materials such as water, gas, air, oil, and heating hot water or steam. They are strictly prohibited. on structural parts.
2. Different Materials
Galvanized seamless steel pipes are made of seamless steel pipes that are galvanized. It is generally made of high-quality carbon structural steel such as 10#, 20#, 30#, 35#, 45#, or low-alloy structural steel such as 16Mn, 5MnV, or composite steel such as 40Cr, 30CrMnSi, 45Mn2, etc., after hot rolling or cold rolling It's done. Ordinary galvanized steel pipes are generally rolled into pipes from steel plates and then welded into shape. It mostly uses ordinary carbon steel of Q195, Q215, and Q235.
3. Different Physical Properties
The tensile strength of galvanized seamless steel pipe is 410Mpa, and that of ordinary galvanized steel pipe is 195-235Mpa. The pressure-bearing capacity and mechanical properties of seamless steel pipes are stronger than ordinary galvanized steel pipes. Galvanized steel pipes use welded pipes. Because the welding seam of the welded pipe is its weak link, the steel pipe may explode in a relatively harsh environment.
4. Different Galvanizing Amounts
In comparison, the galvanizing amount of galvanized seamless steel pipe is less than that of galvanized steel pipe, only about 10-50g.
The steel grades mentioned above are all Chinese standards (GB/T)
