PE100 Pipe

PE100 pipes are made from virgin high-density polyethylene. Polyethylene is a polymer made up of ethylene monomers that, depending on the polymerization process used, are arranged in longer or shorter, more or less cross-linked chains. This length and cross-linking are what give the material its various properties. When cooled, polymer chains can organize into crystalline structures (crystallization) or maintain a disordered “tangled” structure (amorphous structure). Depending on the degree of each structure, polyethylenes with different densities are obtained. PE100 is a high-density polyethylene, ranging from 0.940 to 0.965 g/cm3, with a crystallinity degree of 60–80%. It is also known as low-pressure because it is produced in reactors that operate at much lower pressure than those for low-density polyethylene (30 to 40 atm). The REPOLEN system uses high-density PE-100 polyethylene with a bimodal molecular weight distribution.

PE100 pipes stand out for their light weight, flexibility, and remarkable thermal, chemical, and electrical resistance. PE 100 grade is one of the newest and highest-quality types of polyethylene. PE100 pipes can withstand extreme pressures with a thinner wall. They are also resistant to ultraviolet rays. PE100 offers excellent processability, simplifying the manufacturing process. Moreover, its high flexibility allows cold bending, enabling coiled supply, saving space, and improving transportation. All this contributes to a significant reduction in production costs, making PE100 pipes more durable, higher in quality, and ultimately more cost-effective.

PE100 provides great flexibility to the pipes, making them easy to handle and transport, with a high level of adaptability to the specific needs of each project and facilitating installation, also thanks to their lightness. This flexibility ensures that, in case of freezing, the pipe returns to its original shape after thawing instead of breaking. However, this rarely occurs, as the material is an excellent thermal insulator and can withstand extreme temperatures, preventing freezing in cold climates. Furthermore, PE100 pipes have a long service life due to their high resistance to crack propagation, providing a high level of safety. The most important property to consider for the lifespan of pressurized pipes is their resistance to hydrostatic pressures. High-density polyethylene has a high resistance to this type of pressure.

They also offer excellent resistance to electrochemical corrosion caused by seawater, urban and industrial discharges, etc. Due to their characteristics, PE pipes do not support the growth of any known microorganism, bacteria, or fungus. The mirror-like finish inside the pipe also helps, as it prevents the formation of scale, which could otherwise become a suitable environment for the appearance of unwanted organisms. By preventing scale formation, maintenance costs are significantly reduced. Additionally, this interior finish has a very low roughness coefficient, resulting in minimal pressure loss. PE100 pipes are also resistant to abrasion, high-energy radiation, and ultraviolet radiation.

This material absorbs vibrations and ground movements, such as those caused by seismic activity or the passage of heavy vehicles. It is also an excellent electrical insulator and has a very low noise transmission level. It does not require cathodic protection or protection against galvanic currents. The REPOLEN system features multiple joining methods that create a leak-proof piping system. They are highly resistant to both acids and alkalis, as well as chemicals, making them highly suitable for agricultural, livestock, and industrial use. They have a low wave velocity, essential for irrigation systems. High-density pipes are typically used as the main conduits in irrigation systems. From these conduits, secondary pipes extend, usually made from lower-density materials, which pass through crop fields and better adapt to the terrain’s orography.

Pipes made from virgin polyethylene instead of recycled material are of higher quality, as they provide a health safety guarantee that recycled materials cannot offer. Thanks to being non-toxic, odorless, and tasteless, PE100 pipes can be used to transport potable water for human consumption. Due to our environmental commitment, we use eco-friendly, 100% recyclable materials.

In summary, Reboca’s PE100 pipes can be used for potable water installations, irrigation systems, sanitation systems, reclaimed rainwater, cabling, and even gas due to their high impermeability to gases.
