Characteristics of galvanized seamless pipe
Light weight, easy to handle
Because the galvanized seamless pipe itself is relatively light, the daily transportation and construction are very simple, which can save a lot of time and cost.
Good corrosion resistance
The corrosion resistance of seamless steel pipes is very good. They are resistant to acid, alkali, salt and atmospheric environment. Moreover, it is resistant to high temperature and impact, and does not need regular maintenance.
Good physical and chemical properties
Galvanized seamless pipe has very good physical and chemical properties, its tensile strength is more than 8 times stronger than ordinary steel, and its elastic modulus is also better than ordinary steel. Moreover, it also has good mechanical capabilities and is very easy for daily processing. Long term use will not deform, anti-static ability is good.

Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.
