The introduction of Galvanized steel pipe

Galvanized steel pipe is divided into cold galvanized pipe and hot galvanized pipe, the former has been forbidden, the latter is also the national advocate for temporary use. In sixty or seventy, the developed countries began the development of new pipe material, and have to forbid the galvanized pipe. Chinese Ministry of construction and other four ministries are clarified from 2000 year to forbid the galvanized pipe, the new residential water pipes has been rarely used galvanized pipe, some areas of the hot water pipe is the use of galvanized pipe.

Hot galvanized steel tube is widely used in construction, machinery, mining, chemical, railway vehicles, automotive industry, road, bridge, container, sports facilities, agricultural machinery, oil machinery, prospecting machinery manufacturing industry.

Galvanized steel hot surface has dip galvanized or layer of the welded steel pipe. Galvanized steel pipe can increase the capability of corrosion resistance, to extend the service life. Galvanized steel pipe is widely used, except for water, gas, oil and other generally low pressure fluid pipeline, is used in petroleum industry especially the marine oil field oil well pipe, oil pipe, chemical coking equipment oil heater, cooler, coal run oil exchanger tubes, and the Zhanqiao canal, mine tunnel support rack pipe etc.

Often said that the galvanized pipe, galvanized pipe uses now gas, heating with the kind of iron pipe and galvanized pipe, galvanized pipe as the pipe, after

a few years of using, tube produces produces a lot of rust, outflow of water not only pollute the ware, and mixed with smooth inner wall breeding bacteria, corrosion caused by high content of heavy metals, serious harm to human health.
