Global Piping System Supplier & Complete Solutions VALTEC



PPR pipe is made of polypropylene resin as the main raw material, and is an ideal water supply pipeline. It has the advantages of corrosion resistance, non-toxic, high stability and long service life. PPR pipe can be used in a temperature range of -40°C to 120°C, and the maximum working pressure is 1.6MPa.

PEX-AL-PEX pipe is a composite pipe made of three layers: an inner layer of cross-linked polyethylene (PEX), an intermediate layer of aluminum (for structural support), and an outer layer of cross-linked polyethylene (PEX). This type of pipe has good flexibility and durability, making it ideal for hot and cold water plumbing applications.

PERT-EVOH pipe is made of polyethylene terephthalate (PET) resin and ethylene vinyl alcohol copolymer (EVOH) resin. It is a new type of environmental friendly plastic.

Known for high quality products and competitive prices, we are one of the leading PIPE PRODUCT Pumps Manufacturers and Suppliers. Please feel free to buy PIPE PRODUCT sold in our factory.


Difference Between PPR pipes and PEX pipes

If you're planning on doing some plumbing work in your home, you'll likely be faced with a choice of two different types of plastic piping: PP-R and PEX. So, what's the difference between the two, and which one is better suited for your project?

In general, PP-R is stronger and more durable than PEX, making it the better choice for projects that require a high degree of durability or strength (such as carrying hot water). However, PEX is less expensive and easier to install than PP-R, making it a good choice for smaller projects or those on a budget.

PEX is a cross-linked polyethylene pipe that is flexible and easy to install. It is often used for cold water applications such as plumbing and radiant heating systems. PP-R is a polypropylene pipe that is also flexible, but it is more resistant to heat and chemicals than PEX. It is often used for hot water applications such as solar hot water systems.

PEX/EVOH PIPE is a cross-linked polyethylene (PEX) product with evoh outlayer.Cross-linked polyethylene (PEX)/evoh tubing provides excellent chemical and corrosion resistance, making it ideally suited for harsh water conditions or aggressive installation environment.



1. Broad temperature scope, long usage life up to 50 years.2. Hardness and elasticity, higher inner pressure strength.3. Higher chemical corrosion resistance and environmental stress cracking i.e. more kinds of chemical liquid can be conveyed.4. With low surface tension, it can effectively prevent scale.5. In conformity with potable water hygienic standard, the pipe contains non-toxic components, not being rotten and breeding bacteria.6. Having smoothness both inner and outer walls, the pipe have featured its smallest flow resistance and low noise.7. Good bending property, easy to adjust while installation.8. Light weight, convenient for installation and transportation.  










Pros and cons of PPR PIPE

PPR (Polypropylene Random Copolymer) pipe is a relatively new type of pipe that has many advantages over traditional materials like PVC, copper, and aluminum. PPR is made from polypropylene, which is a thermoplastic that can be melted and reformed. It is also resistant to most chemicals and does not corrode.

PPR pipe is available in a variety of sizes and can be used for both cold and hot water applications. It is often used in residential and commercial plumbing applications. PPR pipe is also finding its way into other uses such as radiant heating systems.

There are several advantages to using PPR pipe:

-It is strong and durable

-It has a smooth inner surface that reduces friction

-It can withstand high temperatures

-It is easy to install

-It doesn't corrode or leach chemicals into the water

-It is flexible, so it can be used in tight spaces

-It comes in a variety of colors

However, there are some disadvantages to using PPR pipe. One downside is that it is not as flexible as PVC, making it more difficult to work with in tight spaces. Additionally, because PPR pipe is made from polypropylene plastic, it may not be compatible with all types of fittings and connections.




Pros and cons of PEX-AL-PEX PIPE


PEX-AL-PEX pipe is a type of composite pipe that consists of three layers: an inner layer of PEX, an outer layer of PEX, and an aluminum core. This type of pipe is used in both residential and commercial applications.


1. PEX-AL-PEX pipe is more resistant to freezing than copper or PVC pipes.

2. It is also more resistant to corrosion than copper or PVC pipes.

3. PEX-AL-PEX pipe is flexible, so it can be bent around corners without the need for fittings.

4. This type of pipe is easy to install because it does not require soldering or glue.

5. PEX-AL-PEX pipe has a long lifespan and is backed by a 25-year warranty in most cases.

6. It can withstand temperatures up to 200 degrees Fahrenheit (93 degrees Celsius).

7. PEX-AL-Pex pipe is available in coils, so there are no joints or fittings required, which reduces the chance of leaks.



-Difficult to Install: PEX-AL-PEXPipe is more difficult to install than traditional copper or PVC pipe because it requires special fittings and tools.

-'Memory Effect': The memory effect of the aluminum core can make it difficult to reposition the pipe once it has been installed.




Pros and cons of  PERT-EVOH PIPE


PERT-EVOH PIPE is a type of pipe that is made from polyethylene terephthalate (PET) and ethylene vinyl alcohol (EVOH). This pipe is used in a variety of applications, including food and beverage packaging, medical devices, and telecommunications.


PERT-EVOH PIPE has several advantages over other types of pipe. It is lightweight and has a high strength-to-weight ratio. Additionally, it is resistant to chemical attack and has a low coefficient of friction.


There are some disadvantages to using PERT-EVOH PIPE as well. It is more expensive than other types of pipe, and it is not as flexible as some other materials. Additionally, PERT-EVOH PIPE can be difficult to work with because it is brittle.
