What are the functions of galvanized steel pipes?

Galvanized steel pipe, as one of the metal pipes used in construction, is widely used in water supply, drainage, gas, steam and other transportation pipelines due to its advantages of corrosion resistance, rust resistance, and durability.
In the construction of industrial and mining enterprises, galvanized steel pipes are used for liquid transportation: water supply and drainage (including industrial and civilian cooling water). Hot dip plastic steel pipe is a cost-effective product upgraded from traditional steel-plastic composite pipes. Hot dip plastic steel pipes are coated with polymer materials through chemical methods on the basis of surface treatment of ordinary steel pipes. The basic process is as follows:

  1. First, melt the plastic powder through high-temperature heating and evenly spray it onto the heated steel.
  2. Then control the temperature of the extruder head at around 210-230 ° C.
  3. After a certain period of curing, a coating is formed.
  4. The coating thickness is generally 0.5-1.0mm
