Galvanized steel pipes can be called galvanized pipes. The main differences between galvanized seamless steel pipes and galvanized steel pipes are:

1. Different uses

Galvanized seamless steel pipes are mainly used for general structures and mechanical structures. Ordinary galvanized steel pipes are welded pipes, which are generally used for transporting medium and low-pressure fluid materials such as water, gas, air, oil, heating hot water, or steam. for structural parts.

2. Different materials

Galvanized seamless steel pipe is made of seamless steel pipe by galvanizing, generally using high-quality carbon steel such as 10, 20, 30, 35, 45, or low-alloy structural steel such as 16Mn, 5MnV, or 40Cr, 30CrMnSi, 45Mn2 Made of hot-rolled or cold-rolled steel. Ordinary galvanized steel pipes are generally rolled into steel pipes and then welded to form, mostly ordinary carbon steel of Q195, Q215, and Q235.

3. Different physical properties

The tensile strength of galvanized seamless steel pipe is 410Mpa, and ordinary galvanized steel pipe is 195235Mpa. The pressure-bearing capacity and mechanical properties of seamless steel pipe are stronger than ordinary galvanized steel pipe; The seam is its weak link, and it may burst open in a relatively harsh environment.

4. The amount of galvanizing is different

In comparison, the galvanized amount of galvanized seamless steel pipe is less than that of galvanized steel pipe, about 10-50g/m2.
