Polypropylene pipe reinforced with aluminum for heating and DHW. Characteristics, disadvantages

Selecting the appropriate plumbing system is essential if you want to heat your house and guarantee that you have a consistent supply of hot water. Polypropylene pipe reinforced with aluminum is one option that has become more and more popular in recent times. This kind of piping offers a number of advantages and is especially made for use in domestic hot water (DHW) applications and heating systems. The features of polypropylene-aluminum pipes will be discussed in this article, along with any potential drawbacks you should be aware of.

Polypropylene-aluminum pipes are made up of several layers, each of which has a distinct function. Polypropylene is a strong, heat-resistant plastic used to make the inner layer. The pipe is then strengthened and stabilized by an aluminum layer placed over this inner layer. Ultimately, an outer polypropylene layer provides an additional degree of defense and guarantees that the pipe is impervious to corrosion and other types of harm.

The superior heat conductivity of polypropylene-aluminum pipes is one of their main benefits. Your home will be efficiently heated thanks to the aluminum layer’s assistance in distributing heat throughout the pipe. This lessens energy use, which lowers heating costs and has a smaller environmental impact in addition to keeping your living areas cozy and warm.

Apart from their ability to conduct heat, polypropylene-aluminum pipes also possess great flexibility and ease of installation. Polypropylene-aluminum pipes are lightweight and simple to move into place, in contrast to conventional metal pipes, which can be cumbersome and challenging to work with. Because of this, they’re perfect for installing new heating systems in confined spaces or retrofitting old ones.

Polypropylene-aluminum pipes have numerous benefits, but you should be aware of their possible drawbacks as well. One frequent worry is the possibility of oxygen seeping in, which over time can cause corrosion and other types of harm. Even in systems where water is continuously circulating, tiny amounts of oxygen can still enter the pipe despite the aluminum layer’s protective shield.

The comparatively high cost of polypropylene-aluminum pipes in comparison to alternative piping materials is another possible drawback. Even though these pipes’ durability and long-term energy savings can help to offset this initial cost, it’s still something to take into account when designing your heating system.

Characteristics Disadvantages
Durable and corrosion-resistant Relatively expensive
Good thermal conductivity May not be suitable for high-temperature applications
Flexible and easy to install May degrade when exposed to UV light
Aluminum reinforcement prevents expansion May not be suitable for outdoor use without additional insulation

Why is reinforcing aluminum

The design region held the answer to these issues. Reinforcing inserts are used in the polypropylene array within the pipe. Two types of materials were chosen: metal and fiberglass, which have different mechanical properties.

Polypropylene reinforcement proved to be a wise decision as the mechanical properties of the pipelines improved dramatically: the coefficient of linear thermal expansion dropped by 75% and its residual value is on par with the same indicator for metal equivalents.

Additionally, the strength indicators are now higher. Reinforced pipes can withstand hot water pressure up to 20 atmospheres, more than doubling their capacity. This led to an outcome that permits the extensive application of aluminum-reinforced polypropylene pipes in water and heating water supply systems.

Aluminum polypropylene foil is deserving of special consideration. Firstly, why was aluminum selected? This metal is distinguished by its consistent ability to shield product surfaces from it with an oxide film. When it comes to oxidizing agents and chemically active substances, aluminum patina (AL2O3) is extremely resistant.

It can only be destroyed by mercury salts. As a result, it offers dependable chemical protection for pipes that are hardening. Simultaneously, the products possess sufficient mechanical strength to tolerate high internal pressure from the transported fluid, which has a thickness ranging from 0.1 to 0.5 millimeters.

Certain metals, like platinum, silver, and gold, have all of the same characteristics. However, for obvious reasons, we will not take their use seriously when producing pipes.

Properties and characteristics of polypropylene reinforced by aluminum

Fiberglar-reinforced pipelines offer several noteworthy features. The walls of these products are permeable to air molecules, one of the most potent natural oxidizers, which is one of their few drawbacks. This causes the metal components of pipelines to corrode more quickly:

  1. In heating systems, this is the inner surface of the boilers, heated heating towers and metal heating radiators, as well as metal locking reinforcement.
  2. Filters, meters of metal – plastic and everything that is subject to oxidation suffer in water supply systems.

Here, aluminum’s strong protective qualities and high metallic density are employed. Aluminum-reinforced polypropylene offers the best oxygen protection and can last up to 50 years in water supply systems.

Polypropylene; PPR marking Compared to other, conventional products, it can withstand higher temperatures and system pressure better, making it a more resilient material for hot water pipelines.

It appears that the pipes’ inner surface is a stable surface, which

  • does not corrode;
  • is not subjected to bacteriological infection;
  • does not besiege lime deposits characteristic of water pipelines;
  • practically not subject to physical wear.

As a result, PPR pipes can be operated for an extended period of time without the system’s physical parameters changing.

Because they are flexible and long-lasting, polypropylene pipes reinforced with aluminum are a common option for home hot water and heating systems. These pipes are appropriate for hot water distribution as well as heating because of the strength and resistance to high temperatures that polypropylene and aluminum combine to provide. There are certain disadvantages to take into account, though, in spite of their benefits. Their comparatively high cost in comparison to other types of piping materials is one of their main drawbacks. Furthermore, the pipes may be more vulnerable to damage from outside impacts due to the aluminum layer. Despite these disadvantages, the general performance and dependability of polypropylene pipes reinforced with aluminum make them a popular option for many hot water and heating systems.

Disadvantages of PPR pipelines reinforced with aluminum

In this instance, we are working with a fairly ideal substance that is dependable and long-lasting. He does, however, have some serious flaws.

Among them is the requirement to remove the reinforcing layer and clean up the ending ends. This is an uncomfortable procedure that, if done incorrectly, could compromise the system’s integrity.

The material’s instability to the effects of radiation and severe loss is another potential drawback. Long-term sun exposure makes it brittle and prone to breaking.

The composition is added up to 2% of the total mass in order to improve the resistance to the UOF. However, it is more dependable to just avoid using PP pipes for pipelines in open spaces.

Selecting the correct pipes is essential for heating and hot water supply in your home. Aluminum-reinforced polypropylene pipes are a common choice for these kinds of systems. They have a number of benefits, such as corrosion resistance, durability, and flexibility. Many homeowners find these pipes to be a convenient option since they are lightweight and simple to install.

Nevertheless, polypropylene pipes reinforced with aluminum have certain drawbacks, just like any other product. Their comparatively high cost in comparison to other types of pipes is one of their main drawbacks. Furthermore, even though they are corrosion-resistant, they might not be appropriate for all kinds of water, especially if it is extremely acidic or alkaline. Furthermore, if the pipes are not handled carefully during installation, the aluminum layer may increase their susceptibility to damage.

Despite these disadvantages, many homes still choose polypropylene pipes reinforced with aluminum for their heating and domestic hot water systems. Because of their resilience to corrosion, strength, and flexibility, they are ideal for these kinds of uses. To find out if they are the best option for your unique needs, you must carefully consider the benefits and drawbacks and speak with an expert.
