In fact, it is a plastic tube. The interface is usually glued together. UPVC pipe has poor frost resistance and heat resistance, so it is difficult to be used as a hot water pipe. Because its strength cannot meet the pressure requirements of water pipes, cold water pipes are rarely used. In most cases, PVC pipes are suitable for electrical conduits and sewage pipes. In addition, in recent years, the scientific and technological circles have discovered that chemical additives that can make PVC softer have a great impact on human kidneys, liver, and testicles, which can lead to cancer, kidney damage, and damage to the human body’s functional reconstruction system. Therefore, it is recommended not to buy.
