HDPE base resins are manufactured in a low-pressure process, resulting in a chain structure with small side branches and a material density range of 0,930-0,960 g/cm3. HDPE materials qualify as PE80 and PE100 in accordance with ISO 4427.

HDPE materials are widely used in both pressure and non pressure applications such as water supply, drains, outfalls, and sewers in pipe sizes up to 1000 mm diameter. The increased stiffness of HDPE is used to advantage in such applications as electrical and communications conduits,
drainage, sewer and storm water.

ADVANTAGES:

•  Lightweight. The density of PE materials is only 0,93-0,96 g/cm3. The weight of PE pipe is much less than that of concrete, cast iron, or steel pipe. The PE piping system is easy to handle and install, and reduced manpower and equipment requirements may result in installation savings.
• Flexibility. In some instances, the pipe's flexibility may remarkably eliminate the usage of fittings and greatly reduce installation costs. HDPE pipe can be bent to a minimum radius between 20 to 40 times the diameter of pipe, which mainly depends on the SDR of the certain pipe.
• Chemical and corrosion resistance. VASEN HDPE fittings and pipe have an excellent corrosion resistance against the majority of chemical substances in systems of potable water, irrigation, sanitary and drains. The PEAD is anti-corrosive and it is not oxidized long time.
• Odorless and insipid.
• Electrical insulating. The PEAD is an electrical conductive and it is not damaged, oxidized or corroded due to the electrolytic action.
• Thermal insulating.
• Low friction coefficient.
• Abrasion resistance. The high resistance to abrasion, flexibility, light weight, and robustness of HDPE VASEN fittings and pipes, has led to their wide usage in applications such as transportation of slurries and mine tailings.
• Ease of installation and union. Electrofusion and butt fusion.
• Recyclable.
• Long expectancy life. When the temperature is 20°C, the expectancy life is 50 years.

Our PERT-ALT-PERT multilayer pipes and accessories are manufactured according to ISO AENOR 21003 and UNE-EN-12165 standards and manufactured in CW617N brass.

The multilayer pipe is composed of 5 layers that make up an inner and outer layer of PERT, a central layer of aluminum, joined together by two layers of adhesive. The aluminum layer is welded to lap to give a complete oxygen barrier.
PERT-AL-PERT pipe undergoes less expansion due to increased temperatures thanks to its aluminum core.

Press-fitting technology and multilayer pipe were seen as the way to proceed. Offering more than 50% speed in installation time and 30% less accessories required when compared to other conventional systems. 
With the increasing demand for high quality multilayer pipe and pressure fittings, VASEN introduces the press-fitting system. A full range of multilayer pipe and pressure fittings. This system is available in high quality brass: CW617N.

It can be used in installations with:

- MULTILAYER PRESS FITTINGS.

- MULTILAYER COMPRESSION FITTINGS.

ADVANTAGES:

• High pressure and temperature resistance.
• Resistance to stress cracking and fracturing, as well as
impact shock.
• Effective response to water hammer that may occur.
• Light weight, which makes it easy to install and transport.
• Easy bending without loss of rigidity.
• Can be used with all types of water.
• Smooth interior surface, thus avoiding scale build-up.
• Resistant to corrosion.
• Very low thermal expansion; much lower than in plastic pipes.

PP-R is short for polypropylene random copolymer, also named as polypropylene type 3.

ADVANTAGES:

• Light weight. The density of the pipes is only 0.89-0.91 g/cm3, which is only 1/9 of steel pipe and 1/10 of copper pipe. It makes handling and installation more convenient.
• Good heat and pressure resistance. The Vicat softening point reaches 131.3°C. Its short-term operating temperature can up to 95°C. And under thetemperature of 80°C, it still can bear some pressure for a long term. That's the best choice for cold and hot water supply pipeline in buildings.
• Long service life. Under proper temperature (70°C) and pressure (10 kg/cm2), its service life can reach 50 years.
• Good corrosion resistance. Vasen PP-R pipes have excellent corrosion resistance to most inorganic ion and common chemical substances in buildings.It is anti-corrosion and does not rust in long termuse.
• Reliable and convenient connection. PP-R material has excellent melting welding performance. The pipes and fittings are made from the same material, joined together by melting welding. Compared to single pipe, the tensile vending and impact strength in joint are much higher, which prevents the danger of leakage, and this kind of connection method also makes the site installation reliable and convenient.
• Nonpoisonous and harmless. PP-R belongs to polyolefin, which is a kind of thermoplastics, whose molecule is only composed of carbon and hydrogen.
• Good thermal and sound insulation property. The thermal conductivity coefficient of PP-R is 0.23 w/m °C, which is only 1/200 of steel pipe (43-52 w/m °C). No need to use insulating materials when used in hot water systems, which saves insulation materials and energy. And it has lower noise when delivery in pipeline system.
• Better water passing capacity. The smooth inner surface of PP-R pipes and fittings have lower friction, which ensure fast running of the water.
• Environment-friendly building material. During production, installation and application, no pollution will be caused to the environment. Meanwhile, the materials are recyclable, which can minimize resource wasting.

The PP-R accessories are used for potable water pipe networks, industrial networks for food products, chemicals and the electrical industry, for purified water and mineral water, air conditioning equipment, heating systems, rainwater harvesting systems, installations of swimming pools, networks for agriculture and horticulture and for solar energy installations.
