Basic knowledge of gi conduit
As we all know, our steel pipe is galvanized in order to improve the corrosion resistance of steel pipes, thereby strengthening the service life and quality assurance of steel pipes. Our galvanizing methods are divided into hot-dip galvanizing and cold-galvanizing, but now our country temporarily supports hot-dip galvanizing and does not allow cold galvanizing. Today, I will introduce you to all kinds of small knowledge about hot-dip galvanized steel pipes.
The price of gi conduit is closely related to the specification of galvanized steel pipe. Different companies, different process technology quality, of course, the price is not the same, we will introduce the industry average. The price of normal hot-dip galvanized steel pipe is about four to six thousand per ton, and the price is at least 4,000, but the highest is only six or seven thousand. We can choose hot-dip galvanized steel pipes of different price according to demand.
How to distinguish galvanised steel conduit can start from its specifications, light from the nominal diameter classification has 16, 25, 32, 40, 50mm and other lengths, the larger the nominal diameter, the greater the quality, the general quality and the larger the price of the caliber The higher the galvanized steel pipe is divided into ordinary steel pipe and thick steel pipe, the thickened steel pipe is heavier than ordinary steel pipe, but the weight coefficient after galvanizing is thicker steel pipe is smaller, in addition, the hot-dip galvanized steel pipe plating The weight of the zinc layer is also required. According to your own needs, the quality of the galvanized layer can be measured. Generally, we stipulate that the average value of the galvanized layer should be no less than 0.5kg per square meter. For example, 5,000 yuan per ton of steel pipe, if the nominal diameter is 16mm, then the weight of rice is about 1.68, the price of one meter is 6-7 yuan. When the nominal diameter is 150mm, the weight of the rice is 18-19, and the price per meter is more than 90 yuan.
About the price of gi conduit and the specifications We introduced these today, I believe that everyone has a certain understanding of these small knowledge.
