PE water supply pipe

The inner wall of the PE water supply pipe is smooth and does not change with the use of time, the friction resistance is small, energy saving, the pressure loss is about 30% smaller than the steel pipe, and the diameter smaller than the steel pipe can be selected. Sanitary performance is good, no additives, no possibility of pollution of drinking water, ISO standard graded polyethylene material is grade 0 (the lowest grade), no mildew material, compared with some other commonly used plastic materials, polyethylene has a much higher resistance to mold, long-term use does not accumulate dirt. PE water supply pipe is suitable for temperature not exceeding 40 ℃, nominal pressure below 1.6MPa, general purpose pressure water delivery and drinking water transportation, mainly municipal buried water supply, building water supply and drainage, farmland irrigation, waterscape engineering, etc. PE water supply pipe comprehensive performance application field of excellent temperature resistance, low temperature embrittlement temperature is very low, can be used in the range of -40 ℃ to 60 ℃, winter installation and construction will not occur pipe embrittlement.

Executive standard

GB/T 13663.2-2018 polyethylene (PE) piping systems for water supply-Part 2: Pipes

Connection mode

1. Electrofusion connection: This method is to first fuse the pipe, and then switch on the power supply to melt the heating wire. After cooling, the two pipes are fused together.

2. Hot melt butt joint: put the PE pipe into the electric heating equipment, and after the heating time is reached, immediately remove the PE pipe and connect it quickly.
