In order to improve the corrosion resistance of steel pipe, the ordinary steel pipe was galvanized.Galvanized steel pipe is divided into hot dip galvanized and electric dip galvanized, hot dip galvanized layer thick, electric dip galvanized cost is low, the surface is not very smooth.Oxygen blowing welding pipe: used for oxygen blowing steel pipe, generally with small diameter welded steel pipe, specifications by 3/8-2 inches eight kinds.Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some of the effective aluminizing treatment.
Most old houses were made of galvanized pipe, gas, heating, now with the kind of iron pipe and galvanized pipe, galvanized pipe as water pipes, use a few years later, the tube to produce large amounts of rust scale, outflow of including not only pollute the clean is provided, and mixed with smooth wall not breed bacteria, heavy metal corrosion caused by the water content is too high, cause serious damage to human body health.60 70 time, developed country begins to develop new-style pipe material on the international, prohibit galvanizing pipe in succession.The Ministry of Construction of China and other four ministries and commissions also issued a document from 2000 to ban galvanized pipe, currently the new cold water pipe has rarely used galvanized pipe, some of the hot water pipe is galvanized pipe.
