How to distinguish fakes from galvanized square pipes? Let's talk about it. When we use galvanized square pipes, we often encounter some problems. The pipeline that caused the problem was inferior product. They not only affect the installation but also cause great harm during use. In order for people to better buy and use galvanized square pipes, today's version will show you some ways to distinguish fake and inferior galvanized square pipes.
First, we need to look at the surface.
In addition, if there is a scar on the surface, it means that the raw materials used are not good, and the content of impurities is relatively high, resulting in the generation of scars.
What should I pay attention to when installing anti-corrosion on galvanized square pipe?
Whether the finished product is stacked or full, avoid unnecessary collisions. We should do our best when the crane is loaded. The fewer landings and landings, the fewer external collisions. When the epoxy coal tar coated glass cloth anti-corrosion pipe pays special attention to anti-corrosion coating, the galvanized square pipe is better loaded, and the emphasis is on the anti-corrosion coating. When zinc square pipes need to be installed, the internal wall corrosion protection (such as IPN8710 drinking water corrosion protection) is inevitably damaged. It is best to provide customers with interior and exterior coatings that have been adjusted in the past. I believe they must brush off the damaged surface before monitoring and accepting.
This phenomenon can only be found by careful observation.
Secondly, the surface marks of high-quality products are distributed fairly evenly without cracks. If cracks are found, it means that the quality of the raw materials used is too poor to withstand heat during the production process, which will eventually lead to cracks. The surface of high-quality aluminum veneer should be shinier and the color more uniform, red or pig iron color, that is, inferior products.
The above are precautions when buying galvanized square pipes. Did everyone learn?
