DC51 AISI ASTM 653M EN10327 Galvanized Steel Pipe

Galvanized pipe

DC51 Galvanized pipe means a steel pipe coated with a layer of zinc on the surface. Galvanizing is an economical and effective rust prevention method that is often used, and about half of the world’s zinc production is used in this process.

 

Galvanized steel pipe is to prevent the surface of the steel pipe from corrosion and prolong its service life. A layer of metal zinc is coated on the surface of the steel pipe. This galvanized steel pipe is called galvanized pipe.

 

DC51 Galvanized pipe has the following general characteristics:

 

(1) Surface state: Due to the different treatment methods in the coating and plating process, the surface state of galvanized pipes is also different, such as ordinary spangle, fine spangle, flat spangle, non-spangle and phosphating surface. German standards also specify surface grades.

 

(2) The galvanized pipe shall have a good appearance and shall not have defects harmful to the use of the product, such as no plating, holes, cracks and scum, excess plating thickness, scratches, chromic acid dirt, white rust, etc.

Application:

Galvanized steel pipes are widely used in construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.

Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated zinc layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and as oil heaters and condensators in chemical coking equipment. Pipes for coolers, coal distillate wash oil exchangers, pipes for trestle pipe piles, and support frames for mine tunnels, etc.

 

(1) It has high strength and strong deformation ability, and has good adhesion and welding performance.

 

(2) It has the characteristics of good overall rigidity, good seismic performance, good thermal insulation performance, long service life, large space, short construction period, and low investment. This series of steel has high strength and is generally used in house construction.

 

(3) It has strong corrosion resistance, has strong corrosion resistance, and has a smooth surface and exquisite appearance. It can generally be used for surface building materials or structural parts, and can be used for roofs, walls, waterproof boards, trenches, underground Pipes, snorkels, upholstery, fencing, steel frames, etc.

 

 

Classification by production and processing methods

(1)Hot-dip galvanized steel pipe. Dip the thin steel pipe into the molten zinc tank to make the thin steel pipe with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the coiled steel pipe is continuously immersed in a galvanizing tank with molten zinc to make a galvanized steel pipe;

(2)Alloyed galvanized steel pipe. This kind of steel panel is also made by hot dip method, but it is heated to about 500℃ immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized pipe has good paint adhesion and weldability;

(3)Electro-galvanized steel pipe. The galvanized steel panel manufactured by electroplating has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized panels;

(4)Single-sided galvanized steel and double-sided galvanized steel. Single-sided galvanized steel pipe, that is, a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized pipe. In order to overcome the shortcomings of one side without galvanizing, there is another kind of galvanized pipe coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized pipe;

(5)alloy, composite galvanized steel. It is an alloy made of zinc and other metals such as aluminum, lead, zinc, or even a composite piped steel pipe. This kind of steel pipe not only has excellent antirust performance, but also has good coating performance;
