About PEX-EVOH PIPE

 

PEX-EVOH is a type of cross-linked polyethylene (PEX) pipe that is used for potable water applications. It is made by extrusion process and has an EVOH barrier layer to prevent oxygen from permeating the pipe and leaching into the water. PEX-EVOH pipe is more expensive than regular PEX pipe but it has a longer lifespan and is more resistant to degradation.

1.Application of PEX, PEX-EVOH PIPE

Polyethylene (PEX) is a semi-crystalline thermoplastic with good chemical resistance and flexibility. PEX has been used in the past for a variety of applications including: food and beverage packaging, medical tubing, and hot and cold water plumbing. PEX is now being used as a pipe material for potable water, radiant heating, snow melting, and cooling applications in residential and commercial construction. PEX pipe is manufactured by extrusion in sizes from 3/8" to 2" nominal diameter. Pipe lengths are typically 50' or 100'.

 

2.Features of PEX, PEX-EVOH PIPE

PEX-EVOH pipe is a high-performance, cross-linked polyethylene pipe that offers superior resistance to stress cracking and chemicals. It is also resistant to UV light, making it an ideal choice for outdoor applications. PEX-EVOH pipe is available in a variety of sizes and lengths to meet your needs.

 

- PEX pipe has a smooth inner surface that is less likely to harbor bacteria or accumulate mineral deposits.
- PEX is available in coils or straight lengths, and it can be bent to negotiate turns without the need for elbows or couplings.
- PEX pipe is flexible and can expand and contract slightly with changes in temperature, making it less likely to burst in freezing conditions.
- PEX pipe can withstand high temperatures (up to 200°F/93°C) and pressures (up to 80 psi), making it suitable for hot water applications.
- PEX pipe is resistant to many chemicals that would damage other types of piping materials.

3.Advantages of PEX, PEX-EVOH PIPE

PEX-EVOH pipe has become the most popular type of composite pipe in recent years. PEX-EVOH pipe is made of PEX material and an EVOH barrier layer. The main advantages of PEX-EVOH pipes are:

1. Excellent oxygen barrier performance, which can effectively block the diffusion of oxygen and other gases, and prevent the deterioration of food quality;

2. Good heat resistance, which can be used in hot water applications;

3. Good chemical resistance, which makes it suitable for use in aggressive environments;

4. Good flexibility, which makes it easy to install;

5. Lightweight and easy to transport;

6. Recyclable.

 

4.Technical Specifications

▪ Produced diameters 16*2.0; 20*2,0.

▪ Working pressure 6 bar at a temperature of 80 ° C.

▪ The maximum transient temperature is up to 95° C.

5.How to choose PEX-EVOH PIPE?

 

There are many factors that need to be considered when choosing the right type of PEX Pipe for your project. The first thing you need to decide is what kind of project you are working on. Are you looking for a pipe that will be used for potable water applications or for non-potable water applications?

The next thing you need to consider is the diameter of the pipe that you need. PEX pipes are available in a variety of diameters, so it is important to choose the right size for your project.

Another thing to consider is the length of the pipe that you need. PEX pipes are available in both long lengths and short lengths, so it is important to choose the right size for your project.

Finally, you need to decide if you want a PEX-EVOH pipe or a regular PEX pipe. PEX-EVOH pipes have an oxygen barrier that prevents oxygen from entering the piping system, which can cause corrosion.
