Some people think that the reason why ppr tubes of different brands cannot be welded together directly is that there are subtle differences between the ppr tubes produced by different manufacturers. In fact, this is not the case. For example, a house that has been renovated for many years needs to be redecorated. Even if you buy the same brand of pipes, one of them has been used for several years, the other has been subjected to water pressure, and the other has not been subjected to water pressure. The difference is bigger. In such a situation, it is obvious that they cannot be connected.
In fact, the temperature control of different welders is not so precise, and the temperature difference will be relatively large; on the other hand, when welding water pipes, everyone has different operating techniques and operating strengths; the impact of these differences is far greater than that of different brands of ppr pipes. In other words, the reliability of ppr pipe welding has a lot to do with the plumber's technology. Of course, when different brands of ppr pipes are welded and connected, there are certain requirements for the diameter and wall thickness of pipe fittings and pipes, that is, pipe fittings and pipes with the same diameter and wall thickness. If the diameter is inconsistent, it needs to be directly welded by reducing the diameter, but the pipe cannot be welded.
Being able to use the same brand of ppr pipes for home hydro installation is the best option. If the same pipe or pipe fitting cannot be purchased for various reasons, it should also be noted that the purchased product must be a qualified product, and the quality level must not be lower than the original pipe. Finally, whether it is a newly renovated new house or a water channel transformed from an old house, a pressure test must be carried out after the installation is completed.
