PE Spiropipe

PE Spiropipe

Spiral pipes are two-layer corrugated pipes made of high-density polyethylene and consist of an inner smooth wall and external corrugated spiral wall. The tube is produced by winding the profiled outer layer (reinforcement) of high-density polyethylene with corrugated profile on a smooth inner layer that is extruded and welded in continuity. The outer layer consists of smaller ribs high-intensity hose coated with polyethylene, and the inner layer consists of high-density polyethylene. Presence of profiled hose in the outer layer significantly improves the strength of the pipe itself. For this reason, PEŠTAN PE Spiropipe can be produced in different classes of stiffness.

Advantages of the PE Spiropipe: Durability, Saving time, Maintenance, Hydraulics, Waterproof, Lengths and Usage.

  • Production program Peštan PE SPIROPIPE spiral pipes for large sewer systems or non-critical transport of water includes pipes produced from the highest quality polyethylene PE 100 with profiled reinforcement in the ribs, in diameters of Ø300 up to Ø1200, and in the coming period will begin with the production of pipes in diameters to Ø3000.

    Also, these pipes are produced in standard length of 6m. They can also be produced in other lengths, according to project specification.

    Peštan PE SPIROPIPE spiral pipes are produced in more variants of strength/resistance to the external load (depending on the step of the profiled outer layer for reinforcement as well as depending on diameter):

    SN 2 KN/m²

    SN 4 KN/m²

    SN 8 KN/m²

    SN 12.5 KN/m²

    SN 16 KN/m²

  • Application and installation

    Inner diameter and hydraulic characteristics of Peštan PE SPIROPIPE spiral pipes remain the same over the time, regardless of the type of profile, thanks to the strong reduced roughness and low adhesion of the inner pipe walls. The nominal diameter corresponds to the effective inner diameter of the pipe, with tolerances allowed according to reference standards.

    Connection of the PE SPIROPIPE
    Peštan PE SPIROPIPE spiral pipes connect in two ways.

    The smaller diameters are connected over the socket into which the EPDM rubber is mounted.
    This type of connection is most widespread due to its own simplicity and speed of performance. At the female’s end of pipe, the rubber was inserted during the production and it is homogeneously coupled with a muff. The male and female parts of the connection are performed in accordance with the parameters by the EN standard 13476.

    The rubber is made in accordance with EN 681-1.

    The larger diameters are connected either with the rubber band

    or electrofusion welding.

    Peštan PE SPIROPIPE SPIRAL pipes are manufactured with an extended socket in which it is possible to insert two rows of electrodes for electrofusion welding, which ensures additional safety and allows to increase the system’s resistance to internal pressure (up to 3 bar).

    Types of profiles
    Peštan currently offers three basic pipe profile products to its customers:

    1. Peštan Spiro PR
    2. Peštan Spiro CPR
    3. Peštan Spiro OP
