The advantages of using water supply pipes made of polyethylene PE 100 and PE 80

  • corrosion stable which enables low maintenance costs and long-term use
  • the flexibility that enables coiling the pipes in rolls, less joints, simpler and faster pipe laying, significantly reduces sensitivity to ground movements and subsidence. It also provides an advantage when renewing worn out pipelines.
  • light pipe weight makes the use simpler and lowers the costs of transportation
  • excellent chemical resistance – to acids, lye and solvents
  • great resistance to bruising caused by abrasive parts in water
  • simple connection with welding or mechanical fittings that provide a long term tightness of pipe systems at low costs

Pipes made of PE 100 have additional advantages

  • substantially enlarged, long-lasting hydrostatic firmness that opens new possibilities and justifies the production of pressure pipes in greater size
  • less sensitive to higher temperatures
  • higher temperatures will slow down the deterioration of firmness
  • less sensitive to low temperatures – pipes are useful even at temperatures of 0°C or lower for they are less susceptible to brittle fractures
  • greater resistance to fast as well as slow spreading cracks

Choosing appropriate pipes

Pipes should be chosen depending on where they will be used. In standard water supply network for main supply of water, pipes with a diameter over 110mm are used. For house installations with lower pressure, pipes of smaller sizes are used. The branching of the distribution system should also be taken into account. Where there are more branches and consequently more changes of flow-direction, an appropriately flexible material should be used (for example PE 80). Main water supply that connects the location where the water is prepared with the distribution network is usually done with pipes made of PE 100.

Modern and safe water supply system

Pipes welded together and made of polyethylene represent a long-lasting tight pipe rod. Together with connecting elements long-lasting pipe systems are made that achieve the highest possible security of operation. The flexibility of PE pipes allows for rational laying techniques, lowers costs, in the event of terrain subsidence or movement, no cracks or breaks appear as they do with rigid pipes made of traditional materials.
