Galvanized steel
Hot-dip galvanized steel pipe is pickled, first remove iron oxide
on the surface of the steel pipe, after pickling, wash with
ammonium chloride or zinc chloride or mixed aqueous solution tank
of ammonium chloride and zinc chloride, and then send it to the
hot-dip plating tank. Hot-dip galvanizing has the advantages of
thick galvanized layer, uniform coating, strong adhesion and long
service life. A complex physical and chemical reaction occurs
between the steel matrix and the molten electrolyte solution to
form a corrosion-resistant zinc alloy layer with a dense structure.
Pure zinc layer, alloy layer and steel matrix are fused together.
Therefore, it has strong corrosion resistance
Galvanized pipe may be cut, machined, or welded in the usual manner
for ordinary steel, but should be adequately ventilated to avoid
inhalation of fumes when heated. The sawed ends of our pre-cut
lengths are not galvanized and should be treated with a cold
galvanizing compound to maintain protection once your project is
complete. Any drilled or welded areas should also be treated
Application of galvanized steel pipe
After galvanizing, these metal pipes can be used for many different
purposes such as: water pipes, gas pipes, chemical pipes, sanitary
pipes, HVAC pipes and industrial pipes. They are often used in
building construction and the development of water systems because
they are very durable and last longer than other types of pipes
such as PVC (polyvinyl chloride) or copper pipes
A common application for galvanized steel pipe is water and gas
systems in building structures. Because of their corrosion
resistance, steel pipes are ideal for plumbing and HVAC (heating,
ventilation and air conditioning) applications where durability is
required. They also make excellent chemical pipes because they
withstand high levels of corrosion and rust better than other types
of pipes
The benefits of using galvanized steel pipe
There are many benefits to using galvanized steel pipe, such as
excellent corrosion resistance, low cost compared to other
materials such as PVC (polyvinyl chloride) or copper, high
durability and strength, and efficient heat transfer properties.
Since they do not easily corrode or rust, these metal pipes can be
used in both indoor and outdoor applications. They're also
lightweight, easy to install, flexible enough to get around corners
with ease, yet strong enough to withstand shocks from earthquakes
or extreme weather conditions
