Installation Pipes can be installed under or above the floor. The installation is very easy and quick. However, one has to pay attention to the following simple points when installing polypropylene pipes: Pipes have to discharge the radial and axial extensions; compensations may be done using fixed points, supporting bracket sleeve (allowing pipe to slide).

Welding technique The quality of an installation depends on the tightness, stability and lifetime of its connections. Fusion welding technique is safe because parts made of polypropylene create a homogenous connection, within this process. When the welded joint cools down, it can be fully loaded. The resulting joints are very reliable and they are as strong as the pipe itself. The pipe may even break before the socket welded joint under tension.
Welding takes only a few seconds. After cutting the pipe perpendicularly to its axis, both the pipes and the fittings (these must be clean, if not please clean it with a cloth or alcohol-water solution) are heated with the welding machine (generally up to 260 0C+/-10 0C) and they are joinedwithouttwisting.
Oxygen impermeability Oxygen penetration reduces the operating life by corroding the radiator and the heater device. Oxygen diffusion from the atmospheric air is one of the most common ways of oxygen penetrating into the system. Plastic pipes do not prevent this penetration. The aluminum layer increases the life of the radiator and the heater device by preventing.
Thermal extension in PPR Pipes The PPR pipes have an extension coefficient that is 11 times more than metal pipes. So, this characteristic should be taken into consideration during installation.

PE-RT-AL-PE-RT multilayered pipes
Application areas: Drinking water systems Underfloor heating systems
Description:
Drinking water systems Combining the benefits of metal and plastic material, but avoiding the drawbacks of both, PERT/AL/PE-RT multilayer pipes are an ideal choice for drinking water systems. This pipe is made up of a longitude welded aluminium layer that is surrounded on the inside and outside by layers of polyethylene of raised temperature resistance. The aluminium provides excellent resistance to pressure and temperature. The inner and outer PE-RT layers inhibit scaling and corrosion whilst the addition of aluminium gives the pipe a strength which makes it an excellent alternative to copper.
Underfloor Heating Systems In underfloor heating systems, the barrier layer usually consists of EVOH. Widely used for many years, EVOH has demonstrated a good combination of processability and barrier properties, which prevent oxygen from permeating through the pipe. A drawback of EVOH is the negative impact moisture has on the barrier characteristics. However, the industry continues to look for alternative solutions, and in the meantime uses a protective outside layer of DOWLEX™ PE-RT resins to keep the EVOH barrier functional (five layer structure pipe).
Advantages: Greater thermal well-being. Greater energy saving. Elevated heating surface at low temperature. Uniform distribution of room temperature. Respect of room humidity and hygienic conditions. No alteration of plaster, wooden floors and door and window frames. No limit in architectural design. Highly reliable and flexible for design and installation purposes.

Pex-Al-Pex pipes Ăœnver PEX-AL-PEX pipe is a five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating into pipe. It compensates and reduces snap-back forces and heat expansion with changes of temperature. pex-al-pex multilayer pipe Ăœnver PEX multilayer composite pipe consists of an overlapped or butt welded aluminum core with an inner and outer layer or high temperature-resistant polyethylene. All layers are permanently bonded together by intermediate adhesive layers. The aluminum thickness for Ăœnver PEX pipe has been selected to meet compressive and flexural strength requirements.
Application: 1. Underfloor heating; 2. Heating system of caliduct and wall, the equipment for snow melting in cold regions; 3. Heat and cold pipes for life, solar energy water heater, irrigation engineer in agriculture; 4. Pipes for coal gas and natural gas, air-condition and blower; 5. Pipes for electric wire and cable; 6. Pipes for oil and industrial liquids transportation.
Advantages: 1. Healthful, not poisonous. The pipe has the same strength as the metal pipe. Easy to bend, reluctant to retain former shape; 2. Easy to cut and install. It can be connected with special fittings instead of screw fittings .Small diameter pipes can be rolled and packaged in desired length and easily bent in order that many directional parts such as elbows or angles are no longer necessary. Much labor cost can be saved; 3. Smooth inner surface of the pipe reduces resistance to the fluids. The ability to transport water is 30% more efficient; 4. Good resistance of acerbity, corrosion and super properties of high temperature, high pressure. The media temperature rangs from -70-110. Heat conduction coefficient is only 0.45W/m-k; 5. Light weight,only 1/10 of galvanized pipes and lower transportation fees and lower cost ; 6. Lifespan of the pipe is more than fifty years (Based on normal use).
PEX-AL-PEX Pipe Application Cold and hot water distribution. The smooth inner of Ünver PEX-AL-PEX pipe prevents deposit accumulation and corrosion, leading up to 30% more flowing than metal pipe. Ünver pipe is easy to bend and install directly to girder or inside wall and cement concrete, while can be found with a simple metal detector. The combination of plastic and metal makes Ünver PEX-AL-PEX tubing a permanently reliable system for its use in all common hot and cold water installation. Solar system, air-conditioning and refrigeration system. Underfloor heating PEX systems. Stable form in bends and over a distance. Ünver PEX-AL-PEX pipe can be directly installed up to 200 meters without any fittings. It works well in a wide range of temperature from -40°C to 90°C. Medical, foodstuff and chemical industries PEX pipe systems. Ünver pipe's inside and outside layers are made of special PE with strong chemical, corrosion and contamination resistance; The aluminum core makes pex-al-pex pipes system the PEX-AL-PEX pipe 100% gas/oxygen-tight. Therefore, as medical and oxygen supply pipe, Ünver PEX-AL-PEX pipe is hygienic and leak-proof, which ensures the purity and safety of its carrying media; As supply pipe for food industry, it can eliminate contamination during manufacture; furthermore the static-free PE layers can also withstand all kinds of acid and alkali solution (in density) below 60°C, which enables the PEX-AL-PEX tubing to be used in the chemical industry with no extra protection.
