With the development of the construction, engineering, and manufacturing industries, galvanized steel pipes have been widely used as an important building material. It has the advantages of corrosion resistance, wear resistance, beauty, and practicality, and plays an important role in protecting steel pipes from corrosion and extending their service life. So, when choosing galvanized steel pipes, which specifications should we adopt?
First of all, we need to understand what galvanized steel pipes are. Galvanized steel pipes are made by immersing steel pipes in molten zinc liquid for galvanizing. The galvanized layer can effectively prevent the corrosion of steel pipes and improve the durability of steel pipes. In China, common galvanized steel pipe specifications include GB/T 3091-2015 “Welded Steel Pipes”, GB/T 13793-2016 “Long Welded Steel Pipes”, etc.
For the selection of specifications for galvanized steel pipes, we can consider the following aspects:
1. Use environment: Different use environments have different requirements for galvanized steel pipes. If it is an outdoor environment, exposed to the atmosphere, oxidation, and corrosion issues need to be considered; if it is an indoor environment, there may be more mechanical friction and wear. Therefore, we need to select the corresponding specifications according to the specific use environment to ensure that the performance of the galvanized steel pipe can meet the needs.
2. Galvanized layer thickness: The thickness of the galvanized layer is directly related to the durability of the galvanized steel pipe. The thickness of the galvanized layer varies according to different specifications. For example, the GB/T 3091-2015 specification requires the galvanized layer thickness of welded steel pipes to be above 65μm, while the GB/T 13793-2016 specification requires the galvanized layer thickness of long welded steel pipes to be above 70μm. Therefore, when selecting specifications, it is necessary to determine the thickness standard of the galvanized layer according to specific needs.
3. Specifications and sizes of steel pipes: Different specifications apply to steel pipes of different specifications and sizes. According to the specific project requirements, we need to select steel pipes that meet the specifications to ensure the quality and safety of the construction. When selecting specifications, pay attention to the provisions of the specifications on the size range and related requirements of steel pipes.
4. Supplier reputation and quality certification: When choosing galvanized steel pipes, we should also consider the supplier’s reputation and product quality certification. High-quality suppliers are usually able to provide galvanized steel pipes that meet national standards and specifications and can provide corresponding quality certification documents, such as factory certificates, quality inspection reports, etc. By choosing reputable suppliers, we can improve the quality assurance of galvanized steel pipes.
In summary, the specification for selecting galvanized steel pipes needs to be considered comprehensively based on factors such as the use environment, the thickness of the galvanized layer, the specifications and dimensions of the steel pipes, and the reputation of the supplier. Only by choosing the right specifications can we ensure that the selected galvanized steel pipes meet the requirements and have good anti-corrosion performance and durability. In practical applications, we can consult professional steel suppliers or consult relevant industry experts to obtain more accurate advice and guidance.
