Application and precautions of galvanized steel pipe, hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicle, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, etc. manufacturing industry.
Galvanized steel pipe is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the 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 pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.
These different types of galvanized steel pipes are produced in some steel processing factories. Let's talk about the requirements for using galvanized steel pipes so that there will be no problems when using them. Let's talk about it in detail below. Also have a certain understanding of the price of galvanized steel pipe.
First of all, the galvanized steel pipe manufacturer did not add any protective agent to the surface of this product when producing this product, so this strip steel does not have any protective layer when using it, so consumers must remember to use A protective film must be added to the surface of this product before, so that no matter what environment the galvanized steel pipe is used in, there is no need to worry about any corrosion caused by external substances.
Secondly, when we choose this product in the market, we must pay attention to it. When choosing, we must choose to choose a surface that looks smooth without any pits and small pits, because only products with a smooth surface are It can be proved that the material density of this galvanized steel pipe is relatively small without any voids during production, so that the hardness of the product can be sufficiently guaranteed.
