Seamless steel pipe product details
Seamless steel pipe is a kind of hollow section, there is no seam around the circular, square, rectangular steel. Seamless steel tube is ingot or billet made by solid capillary hole, then hot, cold or cold made. Seamless steel pipe with a hollow section, as pipe conveying fluid, compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, bike frame and construction using steel scaffolding.
Seamless steel pipe
1: under the construction of the pipeline up more, when building a building, boiler and hot water extraction of groundwater etc..
2 machining, bearing sleeve, processing machinery parts, etc..
3 electrical: gas transmission, water power generation fluid pipeline.
4 wind power plants anti-static tube, etc..
Zinc plating method for seamless steel pipe
There are two types of hot dip galvanizing and zinc plating. Hot dip galvanizing is wet, dry, lead and zinc, oxidation reduction, etc..
The main difference between different hot dip galvanizing methods is to use the method to activate the surface of the tube to improve the quality of zinc coating after pickling. The main methods of production are dry process and oxidation reduction method.
Zinc plating on the surface of zinc coating is very smooth and dense, uniform structure; has good mechanical properties and corrosion resistance; zinc consumption of specific heat galvanized 60% ~ 75%. Zinc plating technology has a certain degree of complexity, but on the one side coating, the inner and outer surface of the different thickness of the coating, as well as thin wall galvanized steel are required to use this method.
