• Increased resistance to tension
• Low resistance to flow
• Chemical and biological inertness
• Material neutral to the environment - polyethylene is 100% recyclable and reusable

For traditional (open tranch) installation:

• In open trenches without bedding and filling according to EN 1610, EN 1046, EN 12327, EN 12007-2 (does not apply to soil filled in around the pipe)

For alternative installation methods:

• Laying into the soil with a plough or a milling cuter according to EN 1610, EN 1046, EN 12327, EN 12007-2 (does not apply to soil filled around the pipe)
• Horizontal directional drilling according to EN 12889, EN 14457

           
Horizontal directional drilling is used for the construction of new or the reconstruction of old pipelines. The old
pipelines can remain fully functional during the reconstruction. Only short term interruptions of work may occur in order to
perform new connections. Use of this method is suitable for areas where trench works must be avoided due to, for instance:
water bodies, roads and railroads, squares, buildings, etc.

• Drawing into the old pipe (relining) according to EN 12889, EN 14457

           
Relining method is used for reconstruction of old pipelines. An ULTRASTRESS pipe with a slightly smaller diameter is drawn into the
old pipe. This method is used in several cases of reconstruction. Only the beginning of the pipeline span that has to be reconstructed
and junctions of the pipe are excavated during the works.

• Burst lining according to EN 12889, EN 14457

           
Burst lining is used if the old pipeline is heavily deformed or its diameter does not conform with the new requirements. A hydraulic burst
head is used as the guide, which builds the way for the new pipe. The specific nature of the method permits the drawing in of a
pipe of the same diameter or larger than the existing one. Advantages of the method:

1. Reconstruction of easily bursting pipes made of materials like ceramic, concrete, cast iron, polymer, steel, etc. is possible.
2. The flow rate parameters of the new pipe are higher or equal to the throughput capacity of the reconstructed pipe (drawing
   in of a pipe with larger diameter is possible).
3. Compact equipment permits operation in restricted conditions.

EVOPIPES PIPE CLASSIFICATION ACCORDING TO PAS* 1075

* PAS = Publicly Available Specification serves as an addition to the existing system of normative acts and directives and refers to polyethylene pipes that are intended for installation using alternative construction methods.

Type 1 – monolith wall pipe made of PE100 – RC material.

Type 2 – 2 layer pipe made of PE100 – RC material, 10% VISIO layer, 90% base layer.

Type 3 – monolith wall pipe made of PE100 – RC material with polypropylene (PP) protective layer, the green lines identify additional protective layer.
