1. PPR tube
✔️ Advantages: clean appearance, soft color, completely suitable for the beautiful needs of modern families, so now most of them are using PPR tubes; At the same time, heat resistance, pressure resistance, non-toxic, light weight, easy construction, the inner wall is smooth, low flow resistance, low noise, no scaling.
❌ Disadvantages: the brand is more careful to choose, choose PPR pipe need to pay attention to the quality of the brand, good pipe raw materials are pure PPR pipe, but inferior pipe only uses part of PPR raw materials, there is a big difference in performance;
⭕️ choose double layer instead of single layer PPR, single layer is a single layer PPR pipe, and double layer is an outer layer PPR pipe + an inner layer of antibacterial pipe ❗ but the double layer PPR pipe has limited high temperature, the general temperature range is controlled in 0-80 degrees, it is recommended to choose double layer PPR for cold and hot water pipes in daily life, and it is recommended to use a single layer for hot water pipes exceeding 80 degrees, because the double layer may fall off!
2, pure copper pipe
✔️ Advantages: bacteria-free, corrosion resistance, high thermal effect, fire resistance, pressure resistance, good environmental performance, can be used repeatedly;
❌ Disadvantages: heat conduction is fast, need to cover the plastic box to prevent heat dissipation blowing agent, the price is more expensive, easy to form green, difficult to install.
3, aluminum-plastic pipe
✔️ Advantages: no scaling, corrosion resistance, pressure resistance, temperature resistance, impermeability, light weight, easy installation, flexible, suitable for use in home decoration. The selection of aluminum-plastic pipe mainly depends on whether the outer wall is smooth, whether the trademark and specifications are clear; There is no delamination between the aluminum layer and the plastic layer, and a good aluminum-plastic pipe has no delamination.
❌ Disadvantages: when used as a hot water pipe, long-term thermal expansion and contraction will cause dislocation of the pipe wall, leading to leakage, and the insulation is poor.
4, steel plastic pipe
✔️ is a kind of composite pipe with plastic inside and steel outside. The hard shell is not easy to break when redecorating, and the plastic in the inner layer can avoid rust and meet the needs of environmental protection.
❌ but its construction requirements are high, easy to connect is not tight, there is a hidden danger of water leakage.
5, galvanized pipe, it is not recommended to use galvanized pipe, generally after a few years of use, the pipe will produce a lot of dirt, the yellow water will not only pollute the sanitary ware, but also include some bacteria bred in the inner wall of the not smooth, and rust will also cause the heavy metal content in the water is too high, seriously affecting people's health.
6, stainless steel pipe, mainly expensive, difficult construction, is now rarely used.
7, UPVC pipe, a plastic pipe, the interface is usually glued, its freeze resistance and heat resistance are not good, so it is difficult to use as a hot water pipe. And its strength is not enough, and it is rarely used as a cold water pipe.
