Recommended guidelines for PEX pipelines


PEX pipeline, or cross-linked polyethylene pipe, represents innovation and progress in piping systems. Through the use of crosslinked polyethylene material, and through the chemical crosslinking process, PEX pipe has made a great breakthrough in performance and application. Compared to traditional metal pipes, PEX pipes are not only lighter and softer, but also easier to install and maintain, providing users with a better experience.

What is a PEX tube

PEX pipe, full name of crosslinked Polyethylene pipe, is an innovative pipe system made of crosslinked polyethylene material. Through a process of chemical crosslinking, strong and long-lasting connections are formed between polyethylene molecules, giving PEX pipes superior performance. This type of pipe is lighter and softer than traditional metal pipes, making it easier to install and maintain.

Why choose PEX Pipeline

PEX pipe has many advantages in winter, whether it is PEX-A, -b or -c type pipe, more frost resistance than rigid pipe. The chemical structure of crosslinked polyethylene (PEX) gives it the flexibility to withstand increased pressure and perform better in the cold winter months. When water freezes in the pipe, PEX is able to expand to adapt to the change and return to its original size after thawing.

Low temperatures do not affect the strength of PEX pipes, except at extreme temperatures. However, antifreeze pipes are not absolutely immune, so it is essential to insulate pipes exposed to freezing temperatures during installation.

Even working in the South, the advantages of the PEX pipeline are not useless. Although the region may not have long or cold winters, it still experiences sudden temperature drops that can cause pipes to freeze.

PEX pipes deliver benefits all year round. In addition to frost resistance.

PEX pipes are an attractive piping option for several reasons for repiping or new construction.

The economics of PEX pipes make them an attractive piping option. Piping costs may be a consideration when installing piping systems from meters to fixtures. Compared with copper pipe, PEX pipe is more economical and the price is more stable. In addition, its flexibility means that the pipe can be bent, thus reducing the amount spent on elbows.

The durability of PEX pipes is also an advantage. PEX pipes are resistant to corrosion and are not affected by electrolysis, which can cause small pinholes in copper pipes to leak. Some brands of PEX pipes, such as IFANPLUS, offer advanced chlorine resistance and UV resistance for up to 6 months to reduce the risk of premature failure.

The efficiency of the PEX pipeline is another advantage. The use of PEX piping with a quickly installed piping system reduces labor costs. The Push-to-connect system, which works with the PEX pipeline, also helps address labor shortages because the learning curve is shorter and new employees can get started faster.

The safety of the PEX pipeline is an important consideration. Because PEX pipes use mechanical fittings rather than welding, there is no need to worry about fire hazards or injury risks during installation. In addition, PEX pipes are resistant to leaching, pitting and mineral accumulation. In addition, unlike copper pipes, PEX pipes do not leave copper traces in the water when they break, making the water cleaner and healthier.

Why are PEX pipeline bad?

Here are some of their downsides:

Tolerance issues – Chlorine does not work well with PEX and may damage pipes and shorten their service life. In areas where water is highly chlorinated, PEX pipes may not be a wise choice.

Photosensitivity – PEX breaks down after prolonged exposure to light and is therefore not suitable for outdoor use.

Heat Sensitive – PEX piping is not suitable for high temperature environments. They are prone to failure when used on water heaters or in conditions with recessed lighting.

Permeability – Unlike copper and galvanized steel pipes, PEX pipes are more prone to damage due to their permeability. Rodents, for example, can easily bite through them.

Chemical issues – Several PEX materials are known to potentially release toxic chemicals and contaminants that impair the taste and smell of water.


In the ever-growing pipeline sector, PEX pipes are the preferred choice for their excellent frost resistance, economy, durability, efficiency and safety. PEX pipes show strong performance and adaptability in cold winter and year-round climates. Its economical and easy to install characteristics make PEX pipe the first choice for modern pipeline engineering, providing users with a more reliable, economical and sustainable liquid transfer solution. Choosing PEX pipeline means choosing advanced, flexible and reliable pipeline technology that provides superior pipeline solutions for all types of construction and engineering.
