Problems that should be paid attention to in the installation and construction of PEX pipes: PEX pipes have lower hardness and poorer rigidity than metal pipes, and should be properly protected during handling, construction and post-pipe installation procedures to avoid improper construction and mechanical damage. In particular, the position of the pipeline should be marked after dark laying, so as to avoid damage to the pipeline during the second decoration; PEX pipe is brittle at low temperature (below 5 °C), so be careful during construction in winter, and use a sharp knife to cut slowly when cutting the pipe. . The installed pipes should not be pressed or knocked, and if necessary, cover the parts that are easily affected by external forces; PEX pipes are easily degraded by long-term ultraviolet radiation, and must be wrapped with a dark protective layer or a dark protective layer when installed outdoors or in direct sunlight. Apply anti-ultraviolet paint.
