What are the precautions when choosing steel pipes
1. When choosing a steel pipe, be sure to check whether the surface of the steel pipe is smooth, and whether the color and gloss are uniform. Then feel whether the inner and outer walls are smooth and flat, and see if there are dents, bubbles or cracks. If there are such defects, it is best not to buy.
2. In addition, when choosing a steel pipe, check whether the relevant product description on the package is labeled. For example, the trademark, brand and production date, as well as the product name and specification, model, etc., to see if there is a clear mark. If you are not sure, it is best not to buy.
3. When choosing steel pipes, it is best to choose brand steel pipes to ensure the quality of the steel pipes. When using, it is necessary to determine which type of steel pipe to use. You can buy steel pipes of the same specification to use, so that the installation performance will be better. Because the raw materials of different brands are different, there may be some disadvantages when welding. Leakage may also occur after long-term use.
