the household water pipes

1. PPR tube
As a new type of water pipe material, PPR pipe has unique advantages, such as non-toxic, light weight, pressure resistance and corrosion resistance. The interface of the PPR pipe is connected by hot-melt technology, and the pipes are completely fused together, so once the installation pressure test passes, there will never be water leakage.
2. Aluminum-plastic tube
The compression resistance and corrosion resistance of aluminum-plastic pipes are better than PPR, but the cost of aluminum-plastic pipes is relatively high, and the supporting pipe fittings are copper pipe fittings or pressing parts, the price is much higher than that of PPR pipe fittings, and PPR takes a long time for water pipes Scale will be generated inside, which will multiply a large number of bacteria and affect human health.
3. PVC pipe
PVC pipe is actually a kind of plastic pipe, and the joints are generally glued. PVC pipes have poor frost resistance and heat resistance, so it is difficult to use them as hot water pipes, because their strength is not suitable for the pressure of water pipes. requirements, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire and sewage pipes.
