PEX pipes are plastic materials used in water supply piping systems. Compared with PP-R pipe, PVC pipe and galvanized steel pipe, this kind of pipe has many advantages. Compared with rigid pipes, PEX is flexible and easy to install, with high heat resistance and long-term durability. PEX diameters range from 32 to 315. The most common sizes of water supply pipes are 6 points, 8 points and 1 inch.
Advantages of PEX tubes
PEX is made of soft and elastic materials. Compared with PVC pipes, PEX is more resistant to cracking caused by freezing. The flexibility also makes PEX easy to install. PEX pipes can be bent to bend around structural frames and other obstacles, thereby reducing the need for holes and slots to accommodate pipes. Bending in the pipeline also eliminates the need for many elbow transition fittings, thereby saving costs and installation time.
PEX saves energy by reducing heat transfer losses. In contrast, metal pipes are particularly prone to heat loss. PEX will not corrode, another advantage compared to metal pipes, especially galvanized steel pipes, galvanized steel pipes will continue to corrode over time. For amateur installers, perhaps the biggest advantage of PEX is that it does not require solder connections. PEX also requires fewer connections and accessories overall, which helps reduce costs and reduce leakage issues. Generally, PEX is installed faster than any other water supply pipeline.
PEX plumbing applications
The PEX pipeline system was developed around 1960 and was accepted by major pipeline constructions in countries around the world.
The standard method of installing a PEX tube is to connect it with a barbed fitting and a special metal crimp ring fixed with a crimping tool. After crimping the ring into place, the installer uses inspection tools to check to confirm the diameter specification of the crimp ring.
Application of PEX pipeline
Generally, PEX pipes can be used for:
Water supply pipeline or portable distribution system
Radiant floor heating applications
Heat transfer applications, such as floor cooling, melting snow and ice
Water distribution for hot water applications (including radiators)
Residential fire / sprinkler system
On the basis of choosing the material of the pipeline, it is the consumer that is most suitable for the current situation.
