Rehau pipes: product range and installation recommendations

Rehau products are represented in many modern building retail outlets. Products offered by the company are suitable for engineering systems in a private house or apartment. The range of products represented a huge range. Consider our installation recommendations. They will be useful and professional craftsmen and home craftsmen.

Metal Rehau pipes can be used to organize the following engineering systems:

• water pipes;
• heat supply;
• sewers;
• warm floors;
• conditioning.

Metal pipes of the manufacturer under consideration have the characteristics most suitable for plumbing systems. Besides the fact that pipes are provided with a hygienic certificate, consumers can choose from two main ways of organizing communications.

The company's programs are as follows:

• Implementation of the integrated Raubasic Press system.It requires the use of a pipe of the type PE-Xb.
• Implementation of a comprehensive system for which the use of PE-Xa equipment is required. This kit requires the mandatory presence of a movable sleeve.

Rehau polyethylene pipes feature simple stitching technology. For the assembly of parts, there is a design that represents a set of fixed sleeves. Thanks to technology, robust and reliable piping systems are obtained.

Rehau polyethylene pipes are inferior in popularity to polypropylene pipes, which are cheaper in price. The process of connecting such products is complicated by the fact that it is necessary to use complex equipment. With the wrong approach to choosing a welding device, the connection of pipes can be unreliable.Products of the German company initially exclude the creation of low-quality compounds.

Despite the relative high cost, Rehau pipes have the following advantages:

• High quality characteristics, which means reliability of heating systems.
• Simple installation, which means convenience.
• The ability to create ornate connections through the use of convenient fittings. Additional elements allow you to connect pipes in a short time.

The types of products offered by Rehau are varied.

The best-selling product is Rehau Rautitan Pink heating systems.

• temperature limit of the pipe application - +95 degrees;
• short term, possible use - +110;
• permissible pressure of the system 10;
• diameters of manufactured products - 16–63 mm;
• manufacturer's warranty for trouble-free use of products - 50 years;
• The distinctive characteristic of the pipe is lilac.

Another popular product is Pautitan Stabil. This differs from the previous version in possible diameters - from 16 to 40 mm. The maximum allowable limit is +100 degrees. The strength of the product adds an inner layer of PEX. Test parameters show that this layer is preserved in the presence of damage on the surface shell. Maintained operating pressure in the system up to 10 bar.

The Flex model range is focused not only on the creation of a heating system, but also on the creation of floor heating systems. These are solid pipes of cross-linked polyethylene, with a wall thickness of about 3–8 mm. The pipe is highly durable and flexible. Typical products are covered with an external protective resistant layer. This layer protects pipes from premature abrasions, scratches, and general wear. The protective layer includes ethylene vinyl alcohol. A distinctive feature of products - silver color.

Products from this model range are often chosen for plumbing. Rautitan Flex has characteristics suitable for building drinking water systems. Also products are suitable for hot and cold supply of technical quality.Possible system pressure is 10 bar. Possible constant operating temperature - 70 degrees. In an accident, the pipes do not deteriorate with a brief exposure to boiling water.

Rautitan Flex is sometimes allowed for use in heating systems. The operating pressure of the supply line is 8 bar, and the allowable operating environment is 110 degrees. The diameters of the pipes are very diverse. Products are sold in 6-meter rolls, and also in the form of blocks of 50–100 m.

In the trade of products are 10 meters, as well as in blocks from 50 to 600 meters. Permissible operating pressure of the system is up to 18 bar. When the temperature environment of 20 degrees, the exploited period may be about 50 years. Famous series of the type Rautherm, denoted by S have improved characteristics, ideal for installing underfloor heating.The mounted system should be used continuously with a coolant temperature of about 70 degrees and a possible pressure of 6 bar.

Raupiano Plus - ideal options for sewer systems. Products are particularly suitable for solving problems associated with the installation of silent systems. Polypropylene pipes of this series include noise suppressing mineral additives. Clamps and brackets differ in the same noise-absorbing characteristics.

Rehau corrugation is designed to protect the system from condensation. Usually laid in a single screed. The main purpose of the corrugations - insulation from heating, condensation. Compensation expansion when heated. This product is also used as a cover that excludes damage to the main pipe in emergency situations. The distinctive feature of the product is black.

The German company Rehau is a well-known company in the design and manufacture of high-quality parts for water supply and heating systems. To connect products to each other, system parts such as Rehau fittings and associated assembly parts are needed.

In particular, these are:

• sliding sleeves;
• connecting couplings;
• adapter;
• connecting reinforcing parts;
• fasteners - locking bypass devices.

Rexau fittings and kits are made from innovative polymer bases. In the manufacture of fasteners, the company uses a cross-linked polyethylene of the type RE-X. This type of material is a high-temperature compound with additions in the form of ecological catalysts.

The proposed elements of the connection pipes of the German manufacturer is not deformed, they are not affected by aggressive media, they take the desired shape. This allows the use of products in different operating conditions. Parts are suitable for both heating and water supply systems.

The most popular type of connecting elements are adapters.

These products have differences in types:

• threaded adapter inside and outside;
• RX union nut adapter;
• MX union nut adapter.

Adapter RX, MX - the combined type of connectors. The armature is characterized by a distinctive design. Material production products - bronze. At the same time, the MX adapter is also a brass alloy.

Rautitan PX sliding sleeves are needed for products with threaded connections of similar size. Products are durable, resistant, chemically resistant. Usually needed as a supplement for fastening the sliding mounting sleeves of appropriate sizes.

Rautitan tees are made from innovative polyethylene. Products are needed to connect additional branches to the main branch. Types of tees can be different.

Usually selected in conjunction with the method of installation:

• equal pass;
• with reduced butt;
• with reduced side part;
• with reduced end and side;
• with a larger side.

MX series brass tees are available in the following types:

• with internal thread on the side;
• with internal thread for wall mounting;
• with an increased part of the passage.

Corner bends are suitable for changing the direction of water flow. The company offers users a wide range of products made from various materials. Monolithic squares PX or MX series are produced in versions with angles of 45 and 90 degrees. Threaded connection on the squares is inside and outside. Products are used for fixing water supply and heating systems in concrete walls, in plasterboard verticals.

If you need to connect two straight pipes in the usual way, then it is worth considering connecting couplings PX. The combined base used in these products has an increased thickness. Constructive details of the execution of products are different - equal and transitional.

Of the other parts and repair kits worth noting such details as:

• nipples, brackets, thread-clamps connecting elements;
• dowels, mounting devices, brackets, busbar blocks;
• the fixing chute, a cuff, the taking away details.

It is more convenient to study the full range of this products through the company's catalogs. Fittings and other accessories presented in all names in the catalog are divided according to standard frame sizes T16 to 63 mm, which simplifies the search for products suitable for your system.

Mounting tools may require:

• the dilator (expander), which includes replacement parts with different sections;
• press clamp, in a set with replaceable parts, suitable for different sizes;
• pipe cutter with which it is possible to cut any plastic pipes (scissors);
• measuring tools, which will suit the usual roulette;
• marking marker.

Rehau offers all the necessary tools in one set. The desired products can also be purchased separately.

If we consider each type of tool in more detail, then it is worthwhile to dwell on the newest expanders that help facilitate the assembly process. Expansion parts on sale under the name Quick Change. The distinctive feature of the products is a grooved surface with grooves in the longitudinal direction. Corrugation is necessary so that due to the expansion of the pipe there is no overvoltage of the material.

Products specifically add color stripes. So, if the stripes are green, then the product is suitable for Rutitan Stabil products. If a part has a blue color strip, it means that it can be used for Rautitan Flex, His, Pink products.

If you plan to connect pipelines with PEX fittings, a hand press and suitable connectors are useful.

Kit contains:

• hand press;
• ratchet detail;
• parts with a pin for insertion into products of size 16, 20, 25 mm;
• universal products such as stops for corners and caps;
• interchangeable products for crimping prefabricated construction.

Any tool requires careful handling. The tool must not be thrown, when mounting with an effort to put pressure on the connecting parts. Ensure that fittings are clamped with ease. It is not recommended to touch the moving parts of the products with your hands, there may be a risk of pinching. Inaccuracy in working with the tool leads to the inoperability of products or injury.

The manufacturer gives on his tools when used correctly 18 months from the date of sale, and the full service life of the tools is 5 years.If the installation of pipes and there is little experience, in the works will help detailed assembly instructions that the manufacturer invests in their products. The average cost of the necessary tools in the kit is about 2500 rubles. Installation of pipes should not be carried out without the intended scheme. Drawing is desirable to prepare in advance.

Cutting pipes made according to the drawings. The process of cutting the pipe of the right size is not difficult if you use a pipe cutter in the works.

Each section of the pipeline must be assembled with the appropriate fittings. It is advisable to prepare all pipe sections according to the drawings, and then check the assembly according to the scheme. Before fastening products with radiators, they must be placed on the floor in the correct order.

This work should not be missed if the installation is done in a city apartment. Replacing will require disabling the heating system throughout the house. If you have a special tool for the job, the fittings can be quickly fixed with one turn of the tool. Pipes with fittings are more convenient to assemble with sliding nuts. Nuts need to screw up until it stops, and only then check the overall tightness.Only after complete conviction in the correctness of the assembly can the first test run be done.

The process of assembling Rehau pipes is universal, successfully used both when connecting radiators and when assembling a heated floor. Wiring pipes in a floor heating system is a bit complicated process, since more time will be spent on properly laying pipes over a certain structure. It should be noted that the sleeves used when joining the pipes should be fixed in the following order.

Select a part with a size that fully matches the size of the pipe. The ends of the handle of the tool used should be placed at a right angle. The used attachment must be kept clearly on the expander and fastened on the pin to the stop reinforcement.

The sleeve is put on the pipe connected by a fitting. The size of the liner must be appropriate. The pipe is put on the opposite end of the nozzle with the expander. If you bring the handles of the expander together, the product will expand. The extension end must be connected to the fitting that is to be mounted at this point. A sleeve that was previously installed is attached to the fitting. Press the clip to move the sleeve until it stops.All reliable connection prepared.

It is worth noting that in the parts to be joined all the parts must be arranged in a strictly horizontal order. If misalignments are made, the connection of parts will be unreliable. Installation of pipes is impossible without compliance with safety standards, so crimping is an important detail of the process, which is described in more detail in the next section of our article.

Rehau pipes and fittings allow you to construct lines for any configuration and purpose.

In particular, of the advantages of products noted:

• convenience;
• durability;
• design;
• quality;
• reliability.

It is easy to distinguish original pipes and fakes by certain features:

• visually;
• at cost.

Another positive point is that, unlike galvanizing, the products in question do not need to be welded. In addition, galvanizing can not be hidden in the wall. In comparison with stainless steel, the pipes of the German manufacturer will be cheaper. Inexpensive polypropylene often can not be used under hot water. Stitched polyethylene used in products stronger, better keeps its shape. It is very easy to press fittings with a special tool.Such reviews can be read on most resources.

As it is shown, pressure testing, carried out after the installation of heating systems, hot or cold water supply, heated floors, pipes withstand a pressure that is 2-3 times higher than the working one. For work, experts advise the use of electric crimpers, which are supplied with a mechanical pressure limiter. Handheld equipment must be monitored, taking into account volumes as pumped up. The amount of pressure will show the gauge arrows.

If the assembled system holds the pressure, the arrow will stay in place. If there is a leak, then it must be found and repaired. The pressure test will have to be repeated. Compressed air testing is a more convenient procedure than hydrotesting. During the test, it is important to understand that the selected pump: manual or electric, should be used depending on the volume of the system under test.

Usually manual options are cheaper in cost, undemanding to operational conditions. However, it will take longer to pump up pressure in the system, and it is simply unrealistic to pressurize the system in an individual cottage.Choose the right tool, use only suitable pipes and connectors. Consider the requirements of safety standards.
