Anticorrosion performance of galvanized mild steel pipe

Mild steel pipe

Mild steel pipes and is one of the low carbon steel pipes with low carbon content and the lesser hardness.

Galvanized mild steel pipe is cheap and anticorrosive performance is relatively better related stainless steel pipes. 

Galvanized pipe in the design and production of an important form of full use of the standard design, galvanized mild steel pipe is generally pipe joints, mainly for low domestic water pipes, low cost, good corrosion resistance, connections are made using British Elbow, tee, short sections to achieve, and generally do not have the means to connect welding, welding will destroy the zinc coating, welding slag prone plus, porosity phenomenon and the impact of anti-corrosion effect.

Galvanized mild steel pipe is to use the principle of electrochemical corrosion, cathodic protection and consumed mainly in the steel and zinc anode contact, carbon steel a cathode, zinc as the anode, thus ensuring that the steel from corrosion. Generally used for process instrumentation or process water piping is threaded connections for multi-temperature low-pressure pipeline medium without danger. Galvanized mild steel pipe are generally after surface treatment on its surface coated with a layer of protective film, with hot dip and cold-plated to prevent corrosion.

Galvanized mild steel pipe because of high potential than iron, zinc corrosion first, so it protected the iron pipe, and if not threaded connection, you can also use welding methods, welding room ventilation must be good, because zinc oxide is toxic to humans with acid electrode J422 can be welded.
