PP/PPR systems are a key element of modern sanitary and heating installations. At Onninen we offer a wide range of products in this category. Our portfolio includes high-quality components from renowned manufacturers. Among them we can find brands such as Wavin, Georg Fischer or Aquatherm. Each of them guarantees reliability and durability of the installation.

We often come across questions about the differences between individual PP/PPR systems. It is worth paying attention to several key aspects. The material from which the pipes and fittings are made is of great importance. It affects the thermal and chemical resistance of the entire system. The thickness of the pipe walls and the method of connecting the elements are also important.

Variety of solutions in PP/PPR systems

Our offer includes various products from the "Other PP/PPR systems" category. Customers can choose from a wide range of pipes and fittings with different diameters and parameters. Available are, among others, grey PPRC pipes with glass fibre in diameters of 20-110 mm. We also offer grey homogeneous PPRC pipes in the range of 20-90 mm. For more demanding applications, we recommend WT PPR pipes in diameters of 20-125 mm.

Our experience shows that the selection of appropriate fastening elements is crucial. That is why the range could not be complete without fixed points for fastening pipes. They ensure the stability and durability of the entire installation. Their correct installation minimizes the risk of failure and extends the life of the system.

PP/PPR system selection criteria - what to pay attention to?

Selecting the appropriate PP/PPR system requires taking many factors into account. In everyday practice, we encounter various installation challenges. Parameters such as temperature and operating pressure are of key importance. The chemical resistance of the material is equally important. It affects the durability of the installation in contact with various media.

Many customers ask us about the differences between PP and PPR systems. Both materials have their advantages and are used in different situations. Polypropylene (PP) is characterized by high chemical resistance. Random polypropylene (PPR), on the other hand, has better properties at high temperatures. The choice depends on the specifics of the installation.

Onninen recommends paying special attention to the method of connecting the elements. Welded systems ensure high tightness and durability of the connections. They are ideal for installations of utility water and central heating. In turn, pressed systems allow for quick and easy assembly. They are particularly useful in hard-to-reach places.

Practical applications of PP/PPR systems in various industries

PP/PPR systems are widely used in many branches of industry and construction. In our daily practice, we observe a growing interest in these solutions. They work perfectly in cold and hot water installations. They are also irreplaceable in heating and air conditioning systems.

We recently used the PP/PPR system for a large office complex project. The client required a solution that would withstand high temperatures. At the same time, they wanted it to be easy to install and maintain. They chose PPRC pipes with glass fiber. They provided excellent thermal and mechanical stability for the installation.

In the case of office reorganization, we most often encounter the need for flexibility. PP/PPR systems are perfect for such situations. The ease of modifying and expanding the installation is their great advantage. This allows for quick adaptation of the network to the changing needs of users.

The food industry places special demands on installations. Chemical resistance and material hygiene are key here. PP/PPR systems meet these criteria, ensuring product safety. Their smooth internal surfaces prevent sediment and bacterial growth.

At Onninen we focus on comprehensive solutions for our customers. We offer not only products, but also professional advice. Our experts will help you choose the optimal PP/PPR system. We will take into account the specifics of a given project and individual needs. We invite you to contact us and take advantage of our many years of experience in the installation industry.
