Which plastic pipe is better: PPR, polyethylene or metal -plastic?

The longevity and efficiency of your home’s insulation and heating system greatly depend on the type of pipe you choose. It’s crucial to comprehend the distinctions between the many options—such as PPR, polyethylene, and metal-plastic—in order to make an informed choice.

PPR (Polypropylene Random Copolymer) pipes are renowned for their resilience to corrosion, high temperatures, and wear and tear. Their suitability for heating applications and their resistance to both hot and cold water systems make them popular choices. PPR pipes are also lightweight, which reduces installation costs and facilitates installation.

Because they are flexible and simple to install, polyethylene pipes, also known as PEX (Cross-linked Polyethylene), have become more and more popular in recent years. PEX pipes are appropriate for plumbing and heating systems because they are corrosion-resistant and able to tolerate high temperatures. Because of their flexibility, fewer connections are needed, which lowers the possibility of leaks and makes installation easier.

Plastic’s resistance to corrosion and metal’s strength are combined in metal-plastic pipes. These pipes, which are usually made of layers of plastic covering an aluminum core, are very durable and have good heat conductivity. Metal-plastic pipes are a dependable and long-lasting option for both residential and commercial buildings, and they can be used for plumbing and heating purposes.

Think about things like your particular heating needs, your budget, and the installation requirements when deciding between PPR, polyethylene, and metal-plastic pipes. You can choose the best option for the insulation and heating system in your house by speaking with an expert, which will guarantee years of optimal performance.

Choosing the right type of plastic pipe for your home"s heating and insulation system is crucial for efficiency and durability. When comparing PPR, polyethylene, and metal-plastic pipes, several factors come into play. PPR (Polypropylene Random Copolymer) pipes are known for their high temperature resistance and durability, making them suitable for both hot and cold water applications. Polyethylene pipes are flexible, resistant to corrosion, and easy to install, making them a cost-effective option for underground heating systems. On the other hand, metal-plastic pipes combine the strength of metal with the flexibility of plastic, offering a balance of durability and ease of installation. Ultimately, the best choice depends on factors like budget, intended use, and installation requirements, so it"s essential to consider each option carefully before making a decision.

Polypropylene pipes, PPR or PPRS

Reins or ironers are the colloquial terms for brigades that train in the precise installation of these hoses. The substance is regarded as consumer goods, meaning it is intended for widespread human use. According to the PPR PPR Crash Test, it explodes at 40–50 bars. Metal-plastic, in contrast, is already at 40 bars. Thus, the derogatory term "shirpotreb" demonstrates why the public adores the PPR water source. Good and affordable pipe.

How much it will last?

All materials function identically under normal circumstances, with a 50-year guarantee, in cold water at a pressure of 2.5 to 4 barra. However, polypropylene is also used for heating and under warm floors, where it can reach temperatures of up to 45 degrees and, if in a radiator, 70 to 90 degrees. The higher the temperature, the shorter the polypropylene’s shelf life. Polypropylene pipes in radiators have a lifespan of 15 to 20 years, and even less under high, continuous pressure.

Features of installation

Unpleasant moments include the use of spikes during connection, the formation of numerous polypropylene manufacturers at the cut site, and the occasional malfunction of nozzles and adapters, which results in extra noise during operation. Despite plumbing jokes, some people find solace in the sound of running water.

Cons of PPR:

1. It is believed that polypropylene is morally outdated, and professional construction companies do not work with polypropylene.
2. Large linear expansion.
   For non -reinforced pipes, the linear expansion coefficient is 0.15 mm/ms, for reinforced – 0.03 mm/ms. And this means that when operating in the heating system, the PPR will stretch and sag 5 times more than metal -plastic. Accordingly, give a load from a different angle to the connecting parts and begin to flow. This does not fall under the warranty and is considered a violation of technical operating conditions. The secret of the master may be that they will use short segments or supports under the pipeline, which compensates the linear expansion.
3. A bunch of joints. And this is almost the main minus of the PPR pipes. After all, most joints are hidden. And only this is why, answering the question of which plastic pipe is better, PPR I would like to place in the very last place.

In summary, excellent for casual tap exploring in a city apartment.

Pipe from stitched polyethylene

Thermoplastic hoses like these have to meet the technical requirements of GOST 32415-2013, "Paps of thermoplasts and connecting parts to them for water supply and heating systems," while being produced in the CIS.

It is chemically stable, easily maintains 95 degrees, and can even pass gas through it without leaking. In the nation, you can safely use the remaining piece to insulate the cable; do not conduct electric current. The flawless smoothness of polyethylene material prevents dirt and salt buildup over time.

Between metal-plastic and polypropylene, but closer to PPR pipes, there is a linear expansion. Operationally, plastic is identical to metal; however, because it lacks an aluminum reinforced layer, it is less expensive. incredibly easy to install.

Reviews claim that this is a very pleasant cool pipe that bends, is lightweight, and can be warmed with a hairdryer.

How much will last

We are certain that longer. For over 50 years, sewn polyethylene reliably maintains 90 degrees. PEX pipe varieties possess "genetic memory," meaning that upon curvature, they return to their original position without requiring further adjustments.

Features of installation

Every customer wants to ensure that there are no leaks in the system following installation. However, the pipes do not automatically flow. Only in cases of faulty installation, malfunctioning technology, or mechanical failure. The ability to think quickly and use a technique that enjoys what it does determines the quality of the assembly. Doing "well, letting it go so far, taking money and vanishing from the view is just fraud," after all.

Pros who are truly talented are proud of their creations and request photos of the final product for their own portfolio. This is the master’s reputation and authority, after all.

The use of specific connecting couplings is required to ensure proper segment fitting. When assignment fittings are combined with hoses on pressing technology, the so-called "genetic memory" will function as intended. Obtain a dependable, insoluble connection of segments.

Cons of stitched polyethylene

The ultraviolet exposure is the first drawback. Sunlight, whether direct or indirect, ruins stitched polyethylene and all of its benefits, which is why it isn’t used for street installation. The second is the lack of hoses larger than 25 mm in diameter because producing chemicals is so expensive.

In conclusion, heating systems in homes and apartments are best served by pipe made of stitched polyethylene. Unquestionably among the best plastic pipes available.

Metal -plastic pipes

Products made of metal polymer combine the best qualities of metal and plastic. The hose’s three layers are constructed with stitched polyethylene on the inside, aluminum reinforcing mesh in the middle, and polyvinyl chloride on the outside, which provides UV protection.

After using metal-plastic products for installation and operation, the plumbing teams have a genuine fondness for them. The masters never had to blush during their eighteen years of continuous use of this material in press technology.

There are plumbers’ tanks where a professional can learn about metal and plastics by closing their eyes and listening to the distinctive ringing sound made by the twisted pipe bay.

Although the product is heavy, its stability eliminates the risk of mechanical damage.

Maintains a temperature of 95 degrees and a pressure of 16 bar. The diameter used by the housing and public services is 16–40 mm.

Anti-static, lovely, silently moving water, and readily fixable without specialized tools

How much will last

Samples made of plastic and metal have a 50-year shelf life. If there are trustworthy press films, you must follow the installation to ensure that everything is in order. Joint leaks are these pipes’ weakest point.

Features of installation

The pipe holds a variety of manipulations made with it perfectly, including vintage, twists, snakes, coups, and U-turns. You can figure out how to make the necessary decoction and fix any object, no matter how complex. Even if it is not possible to extract the corroded iron pipe, you can insert yourself into the slightly bigger diameter, old rusted pipe thanks to the metal-plastic combination.

Minuses

The high cost resulting from the intricate manufacturing process and the strength loss during abrupt temperature changes are the drawbacks that we identify.

In summary, this system is ideal for providing water and heating in urban apartments and other establishments where the temperature remains consistent. Not appropriate for cottages or cottages occupied temporarily.

It appears that we have determined the superior plastic pipe. Let’s talk about something else now.

Which brand to choose?

By visiting the wholesale plumbing base’s website, we were able to identify roughly 100 sanitary equipment manufacturers, 29 of which were joint ventures and based in Russia. Trade brands from Belgium, Spain, Italy, Poland, Germany, and Turkey are well-represented. Henco, Rehau, and Valtec were the three most well-known brands among consumers based on reviews. However, the installation teams of construction firms that work with large facilities frequently use 80- and 100-diameter pipes for the main heating system and basement wiring, respectively.

We suggest that you focus on the fact that a competent pipe developer can tell the difference between poor and good connecting coupling quality.

For your home’s heating and insulation requirements, selecting the appropriate type of pipework is essential to guarantee longevity and effectiveness. PPR, polyethylene, and metal-plastic pipes are three types of plastic pipes that should be compared; each has pros and cons of its own.

PPR pipes are a good fit for hot water systems because of their high temperature resistance. Additionally, they have smooth inner walls and are resistant to corrosion, which lowers the possibility of scaling and blockages. PPR pipes, however, can be pricey in comparison to other choices.

Because polyethylene pipes are lightweight and flexible, they are simple to install, particularly in places with bends and curves or small spaces. Their longevity may be increased by their resistance to chemical reactions and corrosion. PPR pipes, on the other hand, might be more appropriate for high-temperature applications than polyethylene pipes.

Plastic flexibility and metal strength are combined in metal-plastic pipes. They are frequently utilized in heating systems where high temperatures and pressures are typical. Long-term dependability is ensured by the robustness and resistance to scaling and corrosion of metal-plastic pipes. They might cost more than only plastic alternatives, though.

In conclusion, a number of factors, including your budget, the required temperature, installation limitations, and the desired lifespan, will determine the ideal choice of piping for your heating and insulation needs. Polyethylene pipes are flexible and simple to install, but PPR pipes are best for high-temperature applications. Pipes made of metal and plastic offer a robust solution for harsh environments. In the end, seeking advice from a qualified plumber or contractor can assist you in making the best choice possible given your unique needs.
