PE feed pipe

The invention relates to the field of PE water pipes, and discloses a PE feed water. The PE feed pipe comprises a PE feed pipe body and water pipe connecting pieces, wherein the water pipe connectingpieces are arranged at the two ends of the PE feed pipe body. An arranged nano antibacterial layer can effectively prevent external bacteria from intruding into the inside of the pipeline, an arrangedfilter layer can effectively filter a liquid in the pipeline, and an arranged thermal insulation layer can insulate the pipeline when the pipeline is at the low temperature, so that the PE feed pipeis better in antimicrobial performance, filtering performance and thermal insulation performance; PE feed pipe reinforcing ribs are arranged, and when the water pipe bears a large internal and external pressure, the reinforcing ribs can enable the pressure resistance effect of the PE feed pipe to be better; when each water pipe is connected, through arranged fusion welding caulking grooves arranged on the inner walls of ins
