Galvanized Pipe treatment process is very important in the drying process
Drying Hot-dip Galvanized Pipe before production:
For Galvanized Pipe processing, galvanized sheet manufacturers need to enter a lot of process, whether before or during processing, or after processing, there are many plans that many people may know to process, so here to share the Galvanized Pipe drying prior to.
1, the first hot Galvanized Pipe in the dip should be hot air before drying, hot air through the dry outdoor flow, in order to eliminate the surface plating agent plating water.
2, hot air drying pits must control 100 ℃ ~ 150 ° between the workpiece, baking dry pit, usually 2 to 5 minutes, for the complex structure of the members should be based on the degree of baking to determine the workpiece surface drying time.
3, dry activity cover must also start without barriers, hot galvanized sheet should be fully dry, hanging dry pit should be immediately, in order to avoid the workpiece in the air for a long time to place the plating agent back tide.
It is very important to process the Galvanized Pipe during the drying process and may affect the production quality of the Galvanized Pipe and the Galvanized Pipe price.
What is the characteristic of Galvanized Pipe?
(1) Galvanized Pipe, pure zinc layer has a dense thick cover on the surface of steel, it can avoid any corrosion solution contact with steel matrix, to protect the corrosion of steel matrix. In the general atmosphere, in the thin layer of dense zinc oxide layer to form a zinc layer, it is difficult to dissolve in water, so the role of steel matrix protection. If the other components of zinc oxide and the atmosphere to form insoluble zinc salt, and then anti-corrosion effect is more desirable.
(2) Galvanized Pipe, with iron and zinc alloy layer, dense, at sea salt mist atmosphere and industrial resistance to atmospheric corrosion characteristics;
(3) due to a strong combination of Galvanized Pipe, zinc - iron miscibility, wear resistance;
(4) Since the Galvanized Pipe has good ductility, it is firmly adhered to the alloy layer and the steel on the substrate, so that the hot stamping can be cold stamping, rolling, stretching, bending and other molding without damaging the coating;
(5) Galvanized Pipe, hot galvanized, equivalent to the annealing treatment, can effectively improve the mechanical properties of steel matrix to eliminate the steel forming and welding stress, is conducive to the rotation of steel structure.
(6) Hot-dip galvanized surface bright and beautiful in Galvanized Pipe.
(7) Galvanized Pipe, pure zinc layer is hot and galvanized galvanized layer of the plasticity of the rich, pure zinc, basically close to the ductility of nature, so it is flexible.
Galvanized Pipe is generally hot galvanized, for example, the use of wire slot cold galvanized, the color has some differences
Cold galvanized thin-walled galvanized on the outside, hot-plated inside and outside plating.
Galvanized welded pipe welded steel pipe galvanized (zinc pot zinc will melt, and then remove the steel for a period of time immersed in zinc liquid cooling and drying). Inside and outside the wall steel pipe and a layer of zinc attached. Generally used for low pressure fluid Galvanized Pipe (ie, water, liquid gas). delivery.
Standard classification of Galvanized Pipes
In order to improve the corrosion resistance of steel, the general steel (clarinet) galvanized.
Galvanized Pipe is divided into hot galvanized, electrical steel zinc two, the thickness of hot dip galvanized layer, galvanized low cost.
Oxygen tube: used for steel making oxygen pipe, usually used to weld steel pipe diameter from 3/8 inch to 2 inch eight specifications. 08,10,15,20 or q195-q235 steel. Due to corrosion, some infiltration treatment.
