After the house is renovated, PB pipes have been used for heating in the past, but now PPR pipes are used more often, as long as they are connected and remodeled where needed.
PB, PE-RT, PPR can be used as hot and cold water pipes, PB, PE-RT can be used as floor heating pipes, and PB can also be used as hot air piece connection. PB has the best performance, followed by PE-RT, and PPR material is slightly worse. This is also reflected in the price. PB, which is more expensive, is called plastic gold.
PPR pipe is a commonly used material for decoration at present. The advantage is that it is environmentally friendly and cheap, and the imported price is slightly more expensive. The disadvantage is that the construction needs to be professional, and the hot-melt technology requires higher. If the hot-melt connection is not done well, water leakage often occurs in the later construction process. Phenomenon.
When repairing and remodeling, it is best not to heat pipes of different materials together. Because the materials and melting points are different, over time, it is easy to age and the connection is not tight, and the most likely to leak. In fact, metal parts can be used for transition. In order to save trouble, the master workers directly melted together. Below is a kind of internal threaded elbow, similar to this situation, one end is PB inner wire, the other is PPR outer wire, the side with metal in the inner wire is connected to the PB tube, the side without metal is connected to the PPR tube, and the PPR tube It is a PPR pipe, which is thermally welded to the PPR pipe, so that no water leaks.
If buried in the dark, all copper pipes can be changed to PB pipes, or they can be cut to replace the inner and outer wires of the plastic-clad copper. If it is an exposed pipe connection, don't move it first and wait for the water to leak before replacing it, because there is a certain probability of water leaking. If there is no problem, there should be no problem within one to two years.
