Galvanized pipe, also known as galvanized steel pipe, is a commonly used steel in construction sites, currently divided into hot-dip galvanized and cold-galvanized two, galvanized steel pipe brands are numerous, according to different selection institutions and standards, brand rankings will be different, how to choose high-quality manufacturers when purchasing galvanized pipes?
First of all, when purchasing galvanized pipes, it is necessary to consider the specifications and sizes of galvanized pipes, and the quality of testing. The mechanical properties of steel are an important indicator to ensure the final performance of steel, the technical parameters of galvanized pipe include tensile strength, yield point, elongation after breaking, section shrinkage, hardness index, etc., Tianjin CLP Iron and Steel as a galvanized pipe industry strength manufacturer to give you detailed guidance, do the following points, whether in the choice of galvanized pipe or galvanized pipe manufacturers can be selected.
1. Set the specifications and dimensions.
The size of the product is the most important consideration in the process of purchasing galvanized pipes, and if you buy the wrong one, the loss will be very large. We can judge whether it is suitable through the product specification table, especially when purchasing special specifications products, we should determine with the manufacturer to ensure that we can get the required products. The specifications and dimensions of the product should be written on the contract, so that everyone can check it and reduce unnecessary trouble.
2. Do a good job of comparison.
When choosing galvanized pipes, don't believe that cheap is not good, and don't choose cheap products without looking at product quality. Too high is not conducive to cost savings, and too low is not enough to buy reliable quality products. When purchasing, you should compare prices among similar products, and then compare the quality of products. Combining many factors such as quality and transportation costs, choose a manufacturer with high quality, low price and easy transportation for procurement. In fact, this process is relatively difficult to grasp, because professional personnel need to have enough understanding of the quality and quality of galvanized pipes, so as to make a good choice.
3. Do a good job in testing quality.
1) The appearance of the galvanized pipe should be smooth, without zinc tumors and burrs, and it should be silvery-white.
2) The galvanized pipe will not be hydrogen embrittlement, no temperature hazard, and can ensure that the mechanical properties of the material remain unchanged.
3) Good corrosion resistance, neutral salt spray test for 240 hours, no obvious impact on performance, can replace part of the hot-dip galvanizing process.
4. The comprehensive strength of the manufacturer.
Generally speaking, large-scale manufacturers have strong comprehensive strength, high production efficiency and stable product quality. Therefore, when you buy, you can understand which manufacturer the hot-dip galvanized steel pipe is produced by accordingly, so that we can also have a better bottom when using. However, if you choose a stronger manufacturer, you may have an increase in products, and we should also take these factors into account when making a choice.
5. The credibility and reputation of the manufacturer.
Finally, we should also have an understanding of the credibility and reputation of the manufacturer, in addition to the quality of the test, the reputation of its products can also represent the quality of the product to a certain extent. If a company has a good reputation, then it can at least be judged that the factory's production is good, the product quality is stable, and it has been recognized by many consumers.
