Difference between malleable cast iron pipe fittings and galvanized pipe fittings
Malleable cast iron pipe fittings are made of malleable steel. It should be noted that although Ma steel is malleable cast iron with toughness, it cannot be used for forging. Ma steel pipe fittings and malleable cast iron pipe fittings are named by pipe material, while galvanized pipe fittings are named by pipe surface treatment.
Malleable steel pipe fittings are made of iron, so it is easy to rust when exposed to air. In particular, our Ma Steel pipe fittings are mainly used for fire fighting and water supply engineering. The pipe fittings are more likely to rust when exposed to humid environment for a long time. Therefore, the surface of Ma steel pipe fittings needs to be antirust treated. The surface antirust treatment of Masteel pipe fittings is generally divided into hot galvanizing and cold galvanizing. Hot dip galvanizing refers to the galvanizing treatment method of immersing the pipe fittings in the high temperature molten zinc solution of 700-800 degrees, so as to cover the surface of the pipe fittings with a layer of zinc. The principle of cold galvanizing, also known as electro galvanizing, is to transfer and attach the zinc hung on the anode to the surface of the pipe hung on the cathode, thus forming a thin and uniform zinc layer.
Ma steel pipe fittings can also be called threaded pipe fittings (threaded pipe fittings), but it should be noted that although most of the galvanized pipe fittings refer to Ma steel pipe fittings, because some welded pipe fittings or other iron pipe fittings also do galvanized treatment on the surface, in a strict sense, galvanized pipe fittings are not equal to Ma steel pipe fitting.
