Rehau products from a German manufacturer have earned the well-deserved trust of a Russian customer. In addition to the window profile, the plant produces Rehau pipes for water supply. They make products from cross-linked polyethylene, which greatly simplifies the process of installing a water supply system.
The main types of pipes and specifications
The following types of Rehau products are presented on the market:
- Rautitan his. The tubes are designed for cold water and hot water systems with a maximum working temperature of +70 degrees and a pressure of 10 bar.
- Rautitan stabil. Products can be used for installation of water supply and heating systems. Thanks to the stabilizing aluminum layer, the tendency of the pipes to linear expansion is reduced significantly. Moreover, from such a layer they become more rigid. They can withstand short-term exposure to high temperatures up to +95 degrees. The diameter range of the Rautitan stabil system is 16–40 mm.
- Rautitan flex. Another type of universal pipes for water supply and heating systems. The inertia time to high temperatures is slightly lower than that of the Rechau Rautitan stabil water supply. The cross-sectional range is 16-63 mm. It withstands the temperature of water or coolant up to +90 degrees.
- Rautitan pink. Tubes that are used only for heating. They withstand the temperature of the coolant +110 degrees for a short time. Cross section from 16 to 63 mm. The color is lilac.
- Rautherm S. This product is the central element of any Rechau water or heating system. The range of sections is from 10 to 25 mm. It withstands temperatures of +110 degrees for a short time.
In their qualities and durability, German pipes are not inferior to copper.
Mounting Features
The main nuance of installing pipes from a German manufacturer is the lack of the need to use welding or additional fasteners. The device system is performed using the technique of cold pressing with a sleeve. This installation method is as safe as possible for humans. In addition, the press provides reliability and tightness of the system. In general, the process of assembling a water supply system from Rehau tubes is designed in such a way that, if improperly installed, the master will immediately see all the flaws. If the system is assembled correctly, its appearance will be ideal.
The installation of the Reachau water supply system takes place in several stages:
- Take a piece of pipe and put on a sleeve. Its chamfer must be pre-installed in the direction of the mounted joint.
- In turn, the lumen of the second tube is expanded using a special expander.
- The prepared section with an expanded hole is put on the fitting of the previous part of the system and the sleeve is crimped using a sleeve.
Even a layman can handle the installation of a Rekhau water supply system.
Advantages and disadvantages of Rehau pipes
The main important advantages of German plumbing products are:
- Easy installation, requiring no special additional fittings.
- The ability to stack tubes with a tension sleeve in the screed. In this case, the risk of leaks with time in the system is excluded.
- Plasticity of products. Rehau pipes are flexible, easily bent at any angle without risk of damage to the integrity of the material. In turn, tubes from HDPE, PPR, PVC cannot be bent. Turns of systems are carried out only with the help of fittings. And this is an additional cost for the installation of water supply.
- Good sound insulation. Due to the use of high molecular weight polyethylene, the movement of water in the pipes is practically not noticeable.
- Lack of tendency to corrosion and plaque formation inside the system.
- Long service life (average 50 years).
- The ability to install the system at temperatures up to -10.
- Product quality due to production in Germany.The Rehau brand confidently holds a leading position in the modern market.
At the Rehau water supply there are also disadvantages. These include:
- The cost of production is an order of magnitude higher than that of conventional PVC or PPR pipes. If you need to buy tees, adapters, then the amount of costs increases even more.
- Lack of elasticity. Water pipe products are difficult to align in an ideal straight line for this reason. Or you have to use special clamps.
- The high cost of a special hydraulic tool for mounting the system. Depending on the diameter of the tubes, it will cost an average of 400 to 2000 cu However, craftsmen recommend just renting such an instrument, then the cost of installing a water supply system will not seem so sky-high.
Rehau water pipes are a good option for those who care about the quality of construction of each square centimeter of a private house. With German products, reliability is guaranteed.
