Conventional (traditional) construction:

• 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)

Alternative installation techniques:

• Laying into the soil with a plough or a milling cutter 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. The 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.

• Conforms to PAS1075 type 1*
• Dimensions of the pipe conform to EN 12201
• Made of high-density polyethylene (HDPE), type PE100-RC
• Following ISO/TR 10358 and ISO/TR 7620, the pipes and fittings possess chemical resistance between pH 2 (acid) and pH 12 (alkaline)

Pipe welding operations:

Buttfusion jointing should be carried out according to ISO 12176-1 standard requirements. Electrofusion jointing should be carried out according to ISO 12176-2 standard requirements.

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.
