Aqua-Plus PP-R pipes in white

Aqua-Plus PP-R pipes - The perfect alternative to metal pipes

Suitable for drinking water ✓ For hot and cold water ✓ Easy processing ✓

Our Aqua-Plus plastic pipes made of white PP-R are available in diameters from 20mm to 40mm with a standard length of 2000mm at favourable graduated prices. The pipes made of polypropylene random copolymer are an excellent alternative to conventional pipe systems made of copper or steel, because these are significantly lighter, absolutely corrosion-resistant and are also characterised by a very low temperature loss. This makes the pipes perfect for installing hot water pipes for drinking water supply or in heating and air conditioning technology.

The two-metre long plastic pipes can be cut to size with simple tools and the welding of the plastic pipes with the various fittings only requires a simple pipe welding device for plastic pipes, which is often also referred to as a socket welding device. With the Aqua-Plus pipe performance system, time-consuming pipe connections using inert gas welding or very expensive pipe clamps are a thing of the past.

Properties of the white plastic pipes made of PP-R

Plastic pipes for water supply are becoming increasingly popular and represent an inexpensive, durable alternative to line pipes made of aluminium composite pipes, copper or steel. The Aqua-Plus pipe system made of PP-R, is characterised by a whole range of positive features, where conventional metal pipes lose out. In order to be able to use them for drinking water supply, the Aqua-Plus pipes have a whole series of national and international approvals and fulfil all norms and standards that are required to be able to use the pipes as transport pipes for water supply or as heating pipes.

In addition to the price savings for the pipes themselves, the shorter installation time is another important factor that contributes to cost reduction. The very long service life of more than 50 years is another argument for the sustainable construction of sanitary and air-conditioning installations. Polypropylene random copolymer - PP-R for short - is an absolutely corrosion-resistant plastic whose surface is so smooth that there is no build-up on the inside of the pipe that could reduce the flow of the pipe over the years or cause contamination of the drinking water. Even in regions with very high water hardness, limescale deposits inside the pipe are not to be feared. The low surface roughness value of 0.006mm also contributes to the fact that the flow resistance of the pipe is considerably reduced. The lower noise emission when liquids flow through is also due to the significantly smoother surface, which can only be surpassed by very expensive ceramic pipes.

In contrast to pipes made of metal, plastic pipes are electrically insulating. In addition, the thermal conductivity of polypropylene, with a value of 0.24 W/mK, is many times lower than that of pipes made of aluminium, copper or steel, so that the heat loss is considerably reduced, especially in hot water pipes. In times of rising energy prices, this is an extremely important aspect, and not only for the installation of energy-efficient heating systems. For the same reason, Aqua-Plus PP-R pipes are also used in air conditioning technology or for geothermal systems.

Our PP-R pipes, which we stock in the most common diameters, are also characterised by a very high chemical resistance. Many branches of industry make use of this advantage by using the pipes as low-maintenance, durable transport pipes for chemical liquids. Thanks to the production from food-safe polypropylene, the pipes are also used in the food processing industry, for example for conveying oils, liquid food additives or fine granulates such as sugar or flour. Here, too, the low friction loss is noticeable, which means that the transport pipe can be operated at a lower pressure, resulting in indirect energy savings.

Advantages of Aqua-Plus pipes made of PP-R

Processing of Aqua-Plus PP-R pipes in white

Thermoplastics, which also include the Aqua-Plus PP-R pipes, can be processed with simple tools. The pipes can be cut to size with commercially available saws for woodworking and the drilling of the pipes, for example for the targeted irrigation of green areas, can also be carried out with a simple HSS drill. In order to create water- and air-tight connections with the PP-R pipe system, the pipes should always be cut at a right angle. Thinner pipes can be shortened very well with a pipe cutter. For larger diameters, a cross-cut saw is the ideal choice. However, when sawing plastic pipes, care should be taken to use a fine-toothed saw blade and a low speed so that the sawdust does not melt into the cut edge. When cutting the plastic pipes to size, it is also important to ensure that they are inserted into the fitting. This means that the insertion depth must be added to the desired pipe length and the pipe cut to a correspondingly longer length. Depending on the pipe diameter, the insertion depth varies from 14mm for a pipe with an outer diameter of 20mm to 20mm for a pipe with an outer diameter of 40mm.

Before welding of the pipe joints can begin, the cut edge should be deburred and freed from dust and possible impurities. Particularly in the case of machining techniques such as sawing, it is advisable to use a round deburrer to ensure a smooth, even cut edge before the pipe and fitting are inserted or fitted into the socket welder for heating. The two elements to be joined by welding must be heated simultaneously for a certain time to achieve a perfect welded joint. The heating time varies depending on the outer diameter and ranges from four to six seconds. These values vary, however, depending on the welding equipment used and the prevailing ambient temperatures. After heating, the pipes must be inserted immediately into the connecting sleeve, reducer or similar. Make sure that the pipe is inserted straight, with a maximum deviation of 3 degrees and is not twisted when inserted. Otherwise, leaks in the welded joint cannot be ruled out. Once the two components have been joined, the welded joint should rest to allow it to cool. For pipes up to 25 mm in diameter, the cooling time is at least two minutes; for diameters up to 50 mm, the welded joint should rest for at least four minutes to achieve a perfect fusion.

Once all components have been successfully connected, the final installation on the wall and ceiling can take place. For this purpose, we also offer the appropriate mounting material for each diameter, including pipe clips, dowels and dowel screws. Depending on the service temperature of the pipe, installation with fixed points and sliding points must be taken into account so that the plastic pipe can expand sufficiently due to the heat effect. In our data sheets for installation, you will find helpful, illustrated instructions for installation including information on the maximum recommended distances between the individual fixings. How large the distances may be depends on the water temperature and the pipe diameter. The thicker the pipe, the greater the recommended spacing. As the temperature increases, the spacing decreases. This is far less complicated than it sounds and so we have created an installation data sheet for each pipe diameter from which all the necessary data can be taken without being confused by the dimensions of other diameters.

In addition to the white PP-R pipes, in the category for the Aqua-Plus pipe system we also carry the matching fittings, for example fittings, elbows, reducers and T-pieces in the corresponding diameters. In addition, we also offer suitable assembly material for the pipes, as well as wall connections and various valves and stopcocks, so that the necessary system components can be ordered for all areas of application.

WARNING: Please note that the processing may vary depending on the pipe diameter and the continuous operating temperature. Detailed information on the heating time, the insertion depth of the plastic pipe in the respective fitting and the cooling time can be found in the installation data sheet for the corresponding pipe diameter in the Downloads tab. There you will also find a detailed table on the pressure resistance and linear expansion of the plastic pipes.
