1) Can seamless steel pipe be galvanized?
Seamless pipe (smls) refers to a steel pipe that is perforated from a whole round steel and has no welds on the surface. It is widely used. Ordinary galvanized pipes are generally made of welded pipes. Can seamless steel pipes be galvanized? The answer is To be sure, galvanizing treatment is to coat the surface of the steel pipe with a layer of zinc, so that the steel pipe is protected by the zinc layer, so that it is not easy to rust, and the seamless steel pipe also belongs to the steel pipe.It is also possible to use galvanized steel, and the performance of galvanized seamless steel pipe is better than that of ordinary steel pipe.
2) What is the difference between galvanized seamless steel pipe and galvanized pipe?
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, and ordinary galvanized steel pipes are welded pipes. It is generally used for the transportation of medium and low pressure fluid materials such as water, gas, air, oil, hot water for heating or steam, and is strictly prohibited for structural parts.
2. Different materials
Galvanized seamless steel pipe is made of galvanized seamless steel pipe, generally high-quality carbon steel such as 10, 20, 30, 35, 45, or low-alloy structural steel such as 16Mn, 5MnV, or 40Cr, 30CrMnSi, 45Mn2, etc. Made of hot-rolled or cold-rolled steel. Ordinary galvanized steel pipes are generally rolled into pipes with steel plates, 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 that of ordinary galvanized steel pipe is 195-235Mpa. The pressure bearing capacity and mechanical properties of seamless steel pipe are stronger than those of ordinary galvanized steel pipe; galvanized steel pipe adopts welded pipe and welded pipe. The welding 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.
