Merchants provide corrosion resistant galvanized elbows

Galvanized elbow is one of the elbow is the surface of the elbow is plated with a layer of zinc, improve the corrosion resistance of the elbow. Galvanizing elbow is divided into two kinds of hot galvanized and electric galvanized, hot galvanized galvanized layer thick, electric galvanized cost is low, the surface is not very smooth. Galvanized bend pipe is divided into cold plating pipe and hot plating pipe, the former has been banned, and the latter is advocated by the country for the time being.

Galvanized elbow use gas, heating, using the iron pipe connection now is galvanized elbow, galvanized Angle as pipe fittings, using a few years later, the tube 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. Sixty and seventy time, developed country begins to develop new type pipe material on the international, ban in succession galvanized pipe and galvanized elbow. The Ministry of Construction of China and other four ministries and commissions also issued a clear ban on galvanized elbows since 2000. At present, the cold water pipes of new communities have rarely used galvanized elbows to connect pipe fittings, and some communities of hot water pipes use galvanized elbows to connect.
