ULTRASTRESS VISIO GAS

HDPE (type PE100-RC) gas pipes with VISIO layer

ULTRASTRESS VISIO GAS


ULTRASTRESS VISIO GAS pressure pipes for gas systems are made from PE100-RC material featuring yellow VISIO layer (10% of wall thickness).

PE100-RC material pipes are resistant to long term expansion of cracks, scratching and point type loads. Point type loads are especially common during assembly of the pipelines using trenchless installation methods (for instance, as a result of friction against the stones that are present in the soil). In case of a point type load, tension and plastic deformations are produced in the material, which may cause cracks in the internal surface of the pipe.

VISIO layer helps to identify the pipe damage that has occurred during installation.

  • Advantages
    • Environmental stress crack resistance during continuos exploitation
    • Optimized resistance to local deformation
    • Raised resistance to mechanical damages
    • Increased resistance to tension
    • Low resistance to flow
    • Chemical and biological inertness
    • Material neutral to the environment - polyethylene is 100% recyclable and reusable
  • Recommended application
    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. 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.

    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.

    * Permissible, if assessment of the condition of the internal pipe coating has been performed in order to avoid external damage to the guided pipe in the amountt of 15% of the pipe wall

  • Technical information
    • Corresponds to PAS1075 type 2*
    • Dimensions of the pipe conform to EN 1555
    • Both layers of high density polyethylene (HDPE), type PE100-RC
    • VISIO layer (10% of wall thickness) allows to visually check if the pipes are free of cuts and abrasions (the maximum depth admitted is equal to 10% of the wall thickness)
    • The black rim of the seam serves as a visual indicator of good quality welding (the black base layer of the pipe is welded) according to the provisions of ISO 12176-1 standard

               

    • Following ISO/TR 10358 and ISO/TR 7620 the pipes and fittings possess chemical resistance between pH 2 (acid) and pH 12 (alkaline)

     

    EVOPIPES PIPE CLASSIFICATION ACCORDING TO THE REQUIREMENTS OF 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.
