Home decoration people often overlook the choice of water supply pipe and pipe diameter, only to find that there are many problems after the stay, such as pipe leaking to destroy the decoration, water pressure is not enough, the water heater can not start and so on.
Pilesa water pipe
Specialist experts pointed out that water pipes must meet the needs of health, and all health indicators of water pipes must meet national standards before they can be used. However, the degree of cleanliness of water does not depend entirely on the pollution of the water quality of the pipeline, but also whether the pipeline used can resist the penetration of oxygen in the outside air into the pipe wall. Long-term oxygen penetration can make bacteria, scale, and moss grow in the pipeline and pollute the water. Therefore, consumers in the purchase of household plastic pipe, it is best to ask the business product quality inspection report, do not figure cheap to buy without factory name, the site of the pipe.
Aluminum plastic composite pipe
The loss of aluminum-plastic composite pipe is small, the coil is easy to transport, can be cut arbitrarily, easy to install, and convenient to construct. However, the accessories are pure copper and they are expensive. Aluminum plastic pipe is made of high-density polyethylene sandwiched with aluminum. The melting point of polyethylene is 140°C, so its long-term high-temperature performance is good. Its supporting use of ferrule nut type and steel sleeve pliers pressure pipe fittings is highly reliable.
PP-R tube
The PP-R pipe is regarded as a green and reliable pipe by the building's water supply and drainage community. Compared with the aluminum-plastic composite pipe, the cost is lower, and the pipe fitting is installed outside the pipe so that the flow rate is not reduced. However, the PP-R tube should not be suspended for a long distance, and a fixing bracket should be set every 50 cm or it is easy to hang down and bend.
PE tube
The PE pipe has a single structure and its overall performance is inferior to that of aluminum-plastic pipes. It is mainly used for floor heating pipes, and floor heating facilities are generally completed by construction companies. Generally, PE pipes are not used for home decoration.
PVC-U tube
The connection of PVC-U pipe is glued. When it is hot, it is easy to fall off and open. It is only suitable for underground pipelines or buried pipelines. If it is used for large-caliber high-pressure water-exposed pipes, special brackets must be designed, especially at the corners, and the impact of water flow will greatly damage the turning points. It is not recommended to use PVC-U pipes for water pipes in home improvement.
Copper tube
Copper pipes have superior hygienic properties, but they are expensive. Brass connections are welded, pipe fittings. The pipeline is easily damaged by subsequent construction or secondary decoration.
