Properties of Galvanized Steel Pipe Welds Galvanizing has been used to protect iron and steel from rusting for over a hundred years in places as diverse as the wire rope used for the suspension cables on the Brooklyn Bridge to gutters on houses. Galvanizing is simply coating of zinc over steel. Like paint, galvanizing protects steel from rusting by forming a barrier between the steel and the environment, but galvanizing goes one giant step further than paint — it also provides electrochemical protection of the steel. Since zinc is electrochemically more reactive than steel, it oxidizes to protect the steel […]

galvanized steel pipe full knowledge Galvanized pipe, also known as galvanized steel pipe, hot dip galvanized and electrogalvanized two, hot galvanized galvanized layer thickness, with uniform coating, strong adhesion, long life and other advantages. Zinc electroplating has a low cost, the surface is not very smooth, and its own corrosion resistance is much poorer than hot dip galvanized pipe. The galvanized steel pipes are widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automotive industry, roads, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery manufacturing industry.
