Rehau products from the German manufacturer have won the well-deserved trust of the Russian buyer. In addition to the window profile, the plant produces Rehau pipes for water supply. They produce products from cross-linked polyethylene, which greatly simplifies the process of installing a water supply system.
Main types of pipes and technical characteristics
- Rautitan his. The tubes are designed for cold water and hot water systems at a maximum operating temperature of +70 degrees and a pressure of 10 bar.
- Rautitan stabil. The products can be used for the installation of water supply and heating systems. Thanks to the stabilizing aluminum layer, the tendency of pipes to linear expansion is significantly reduced. In addition, from such a layer, they become more rigid. They can withstand short-term exposure to high temperatures up to +95 degrees. The range of diameters of the Rautitan stabil system is 16-40 mm.
- Rautitan flex. Another type of universal pipes for water supply and heating systems. The inertness time to high temperatures is slightly lower than that of the Rehau Rautitan stabil. The range of sections is 16-63 mm. Withstands water or heat carrier temperature up to +90 degrees.
- Rautitan pink. Tubes that are used only for heating. The temperature of the coolant is maintained for a short time at +110 degrees. Section from 16 to 63 mm. The color is lilac.
- Rautherm S. This product is the centerpiece of any Rehau plumbing or heating system. Cross-section range from 10 to 25 mm. Withstands temperatures of +110 degrees for a short time.
In terms of their qualities and durability, German pipes are not inferior to copper ones.
Installation features
The main nuance of installing pipes from a German manufacturer is that there is no need to use welding or additional fasteners. The design of the system is carried out using the technique of cold pressing with a sleeve. This installation method is as safe as possible for humans. In addition, the press ensures the 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 perfect.
The Reachau water supply system takes place in several stages:
- Take a piece of pipe and put a sleeve on it. Its chamfer must be pre-installed towards the joint to be mounted.
- In turn, the lumen of the second tube is expanded using a special expander.
- The prepared cut with an expanded hole is put on the fitting of the previous part of the system and the sleeve is squeezed using a sleeve.
Even a non-professional can handle the Rehau water supply system.
Advantages and disadvantages of Rehau pipes
- Ease of installation that does not require special additional fittings.
- Possibility to stack tubes with a turnbuckle in a tie. At the same time, the risk of leaks over time is excluded from the system.
- Product plasticity. Rehau pipes are pliable, easily bend at any angle without the risk of damaging the integrity of the material. In turn, tubes made of HDPE, PPR, PVC cannot be bent. Turning of the systems is carried out only with fittings. And this is an additional cost for the installation of a water supply system.
- Good insulation. Due to the use of high molecular weight polyethylene, the movement of water in the pipes is practically imperceptible.
- No tendency to corrosion and plaque formation inside the system.
- Long service life (50 years on average).
- The ability to install the system at temperatures up to -10.
- The quality of the products due to the production in Germany. The Rehau brand confidently holds a leading position in the modern market.
There are also disadvantages to the Rehau plumbing. These include:
- The cost of production is an order of magnitude higher than that of the usual PVC or PPR pipes. If you need to purchase tees, adapters, then the amount of costs increases even more.
- Lack of elasticity. Plumbing products are difficult to align in a perfect straight line for this very reason. Or you have to use special clamps.
- High cost of a special hydraulic tool for installing the system. Depending on the diameter of the tubes, it will cost on average from 400 to 2000 cu. However, craftsmen recommend simply renting such a tool, then the cost of installing a water supply system will not seem so transcendental.
Rehau water pipes are a good option for those who care about the quality of construction of every square centimeter of a private house. With German products, reliability is guaranteed.
