Galvanized pipe

Galvanized pipe is a pipe made by reacting molten metal with an iron matrix to produce an alloy layer. Galvanized pipe fittings are divided into cold-plated pipe fittings and hot-plated pipe fittings. It has good tensile properties, hardness, toughness, low temperature resistance, corrosion resistance and other mechanical properties.

According to the connection method, it can be divided into socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings. Mostly made of the same material as the tube. There are elbows (elbows), flanges, tees, crosses (cross heads) and reducers (big and small).

The elbow is used for the place where the pipeturns; the flange is used to connect the pipe and the pipe to each other and connected to the pipe end; the tee is used for the place where the three pipes are gathered; Reducers are used where two pipes of different diameters are connected.

Galvanized pipe is mainly used in water supply. Its material is mainly steel pipe plus galvanized anti-corrosion protection layer. However, few people use this kind of pipe now and it is easy to age. It seems that there are famous regulations in China not to use this kind of pipe In 1999, steel was replaced by plastic. At present, most of them are aluminum-plastic pipes and steel-lined plastic pipes. As for the material of the pipe and the pipe, the groove is only a connection method, and it is generally used to connect the pipe with a diameter of 100 or more.
