Galvanized Steel Pipe DX51D
Galvanized Steel Pipe
Galvanized steel pipe makes the molten metal and iron substrate reaction and produces an alloy layer so that the substrate and the coating of both.
Hot-dip galvanising is when the steel pipe is first pickled, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tanks, and then sent to hot-dip galvanising tanks.
After the zinc coating of the steel pipe, the surface layer becomes crystalline and detailed, and resistance to rust corrosion becomes stronger, which can effectively protect the pipe body.
After acid passivation, the surface layer is formed in different colours such as white, green and coloured, which looks very beautiful and can also have a decorative effect.
The galvanised layer has very good ductility and can be cold-drawn and bent without damaging the galvanised layer, which is resistant to rusting and corrosion and is also aesthetically pleasing.
Fire fighting facilities: Hot-dipped galvanized square steel pipe has anti-rust. Anti-corrosion advantages, so it is widely used in fire hoses.
Nowadays, the fire supply pipes are basically all galvanized steel pipes. Whether it is a large number of fire pipes or the fire pipes in the basement, they are basically all galvanised pipes, and then a layer of paint is applied to the outer layer of the galvanised pipes, and that is the red fire pipes that you can see, which are in fact processed from the galvanized square steel pipe and galvanized round steel pipe only.
Structural Tubes
Commonly used in steel structure welding projects, nowadays outside many scaffolding plants, the previous scaffolding all use welded steel pipe, but the welded steel pipe is very easy to rust, in order to avoid rust must also be coated with a layer of paint deal with this problem, nowadays, many new steel structure projects are all immediate application of galvanised pipe, so that can save time and can be used for a longer period of time. Welding projects in general use thinner galvanized rectangular steel pipe, usually of the lower international grade, and the regulations for galvanized steel square pipes are not so high.
With the rapid development of science and technology in our country, hot dipped galvanized round steel pipe is cited in the field is also more and more extensive, and can be said to be all over the national economy of the various production lines and sectors, such as machine manufacturing, transportation, automotive industry, industry, agricultural machinery, petroleum machinery and so on a series of manufacturing industry. Like some electro-galvanised zinc can be applied to aerospace atomic energy and other fields, in China's economic development, plays a vital significance. As galvanised steel pipe has a beautiful appearance and good corrosion resistance, it has been widely used.
