Is the water pipe in the house made of PPR pipe or stainless steel pipe? What brand is better?
To the building materials City, you will find, water pipes are dazzling, PP-R pipe, PVC-U pipe, lining plastic pipe, stainless steel pipe, copper pipe and so on.The water pipe should be stable, watertight, and free from burstingWhat we call safety and durability is the occurrence of accidents that endanger life and family safety in the service life of the water pipe, which can not be used for a long time.
As far as I know, or PPR, stainless steel has been eliminated, and the stainless steel is easy to rust, like home of our own is Su You PPR
This requires water pipes to withstand corrosion, high temperature, frost resistance, and has good mechanical properties. By comparison, the plastic pipe can not withstand high temperatures, easy to occur in the temperature under the condition of large deformation caused leakage, and the compressive capacity is small, easy to brittle fracture, which is not applicable to its long-term heating, should not be used in the cold north, not suitable for high-rise buildings.Composite pipe sets the advantages of metal and plastic in one, but it is because of the expansion coefficient of plastic and metal is different, long-term use will lead to delamination of the pipe, causing harm.We all know of brass, copper in chemical and active sort order is very low, stable performance, strong corrosion resistance. Copper is a kind of metal with a certain strength and excellent plasticity and toughness. It has excellent low temperature performance. Therefore, copper water pipe can resist heat and fire, not aging, and has a certain frost heaving resistance. From the copper pipe on the installation of Peking Union Medical College Hospital in 20s after eighty years of vicissitudes of life, still a good performance on copper pipes can be durable, with long-term safety and reliability of buildings with the same life. In addition, the copper tube is durable and has little thermal expansion rate, and is especially suitable for being embedded in the cement wall without worrying about the cracking of the wall. But copper pipes are more expensive.
