Hygienic and non-toxic: This product is a green building material and can be used in pure drinking water pipeline systems. Heat resistance: Under the specified long-term continuous working pressure, the temperature of the water transported by the pipeline can reach 70°C, and the instantaneous temperature can reach 95°C. Corrosion resistance and non-scaling: It can avoid the troubles of pipe fouling and clogging and yellow spot rust in the basin and bathtub, and it is not limited to the precipitation of water quality and the impurity water that is flushed out. Thermal insulation and energy saving: the thermal conductivity is one-two percent of the metal pipe, which is very effective for heat preservation and energy saving of hot water pipes. Light weight and high specific strength: the specific gravity is one-eighth of the metal tube, with good toughness and impact resistance. Beautiful appearance: The inner and outer walls of the product are smooth, the flow resistance is small, the flow is large, and the colors are soft and diverse. There are many types of white, green, yellow, blue, black, gray, etc., and the appearance is beautiful. Convenient and reliable installation: It adopts hot-melt connection, no wire is needed, and a joint connection can be completed in a few seconds. The connection with the metal pipe and the water heater adopts high-quality copper inserts, which is safe and reliable.
