Approach And Use Of Galvanized Elbow
The galvanized elbow has a modest volume of galvanizing, only ten-50g/m2, and its corrosion resistance is considerably worse than that of scorching-dip galvanized pipe. Regular galvanized elbow manufacturers are allowed to use cold galvanized pipes for water and fuel pipes.
Cold galvanized elbow: The galvanized layer of the cold galvanized elbow is an electroplated layer, and the zinc layer and the elbow base are layered independently. The zinc layer is thin, and the zinc layer is merely connected to the steel pipe base and is simple to fall off. As a result, its corrosion resistance is poor. In new houses, it is forbidden to use cold galvanized elbows as the water supply pipe connection elements.
Sizzling-dip galvanized elbow: A sizzling-dip galvanized elbow is a combination of a molten metal and an iron matrix to create an alloy layer, thereby combining the substrate and the plating. Hot-dip galvanizing is to initial pickle the elbow, in purchase to take away the iron oxide on the surface of the elbow, soon after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous answer of ammonium chloride and zinc chloride, and then Feed into the sizzling dip plating tank. Scorching-dip galvanizing has the advantages of uniform plating, robust adhesion and prolonged support life.
Menangkan Video Game dengan Kiat Hebat Ini The use of galvanized elbows: the use of galvanized elbows. The iron pipe connection for fuel and heating is now a galvanized elbow. The galvanized elbow is employed as a water pipe connection. Right after a number of years of use, a large amount of rust is created inside the pipe. The yellow water that flows out not only pollutes the sanitary ware, but also is mixed with the bacteria that develop on the uneven inner wall. The rust triggers the hefty metal content in the water to be as well large, which critically endangers the wellness of the human body.
In the 1960s and 1970s, created nations in the globe started to build new kinds of pipes, and successively banned galvanized pipes and galvanized elbows. The Ministry of Development and other four ministries also issued a document clarifying that galvanized elbows will be banned from 2000. At present, cold water pipes in newly created communities have rarely used galvanized elbows to connect pipe fittings. In some districts, scorching water pipes use galvanized bends. Head connection.
