 What is galvanized steel channel?Galvanized steel channel is divided into cold galvanized steel pipe, hot galvanized steel pipe, galvanized steel pipe has been disabled, the latter has been advocated by the state for the time being able to use.In the sixty or seventy's, the developed countries began to develop new type of pipe, and it have been banned in succession.China Ministry of construction and other four ministries also issued a civilization indeed from 000 to two years from the use of galvanized pipe as a water supply pipe, the New District of cold water pipe has been rarely used galvanized pipe, and some areas of the hot water pipe is used in galvanized pipe.  Galvanized steel channelis widely used in fire protection, electric power and highway.

   Galvanized steel channel is widely used in construction, machinery, coal, chemical industry, railway vehicle, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery etc. manufacturing industry.

   The surface of galvanized steel channel welded steel pipe or layer.Galvanized steel pipe can increase the corrosion resistance, prolong the service life.The uses of galvanized pipe is very wide,in addition to water, gas, oil and other general low pressure fluid pipelines,especially for offshore oil field of oil well pipe and oil pipe, chemical, coking equipment of oil heater, condensation cooler, coal run oil exchanger tube, and trestle pile, the mine tunnel support frame tube. 

   We often say that the galvanized pipe, gas, heating with that pipe is galvanized pipe, galvanized pipe as a water pipe, after using it for several years, the inner tube produced a lot of rust, outflow of the yellow water pollution is not only sanitary ware, and it is mixed with smooth inner wall of the breeding of bacteria, corrosion caused by the heavy metal content in the water is too high, it is seriously harm to human health.

   Derusting method:Firstly, the surface of the steel surface is removed by using the solvent to clean the surface of the steel,
Then use the tools of rust (Gang Sishua), rust removal loose or inclined, scale, welding slag etc.,
We can use the pickling method.
