  What are the technical requirements for galvanized pipes?

  In order to increase the service life of smls pipes or welded pipes, steel pipe manufacturers often choose galvanized pipes. There are two types of galvanized pipes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick galvanizing layer and has the advantages of uniform coating, strong adhesion, and long service life.
