Cars Zn(0) Hot Dip Galvanized Steel Tube Bridges Ships

Grade:NGHDG-10
 
Product:Excellent corrosion resistance Zn(0) Hot DIP Galvanized Steel Pipe
 
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the country can be used temporarily.In the 1960s and 1970s, developed countries began to develop new types of pipes and banned galvanized pipes successively.China's Ministry of Construction and other four ministries and commissions also issued a clear ban on galvanized pipes as water supply since 2000, the cold water pipes in new residential areas have rarely used galvanized pipes, some residential hot water pipes use galvanized pipes.Galvanized steel tubes are widely used in fire, power and highway applications.
 
Application
 
The use is very wide, from the general engineering structure to cars,Bridges, ships, boilers and pressure vessels and other manufacturing, have been used in large quantities.

 
Advantages
 
a. Because the pipes are galvanized, it is protected from rust and corrosion. Steel rusts after interacting with water or moisture in the air over            time.  By adding a coating of zinc to the pipes, galvanized steel round pipe corrodes much slower, extending the life of the pipes
b. Lower cost than stainless steel
c. Lowest long-term cost
d. Reliable performance
e. Excellent resistance to mechanical damage
