PE-RT Thermo-stable pipes for electrical power systems

Peštan PEHD pipes are high-quality pipes made of premium-grade polyethylene – PE-RT or PE-100.
The inner surface of the pipe is smooth, reducing the contact area between the cable and the pipe, thereby lowering the friction coefficient and enabling long-distance blowing of optical cables.

– Pipes are manufactured in accordance with DIN and EN standards
– Solid (compact) PE pipe construction
– Available as single-layer or multi-layer pipes with smooth ends

  • Peštan PEHD pipes are manufactured in all diameters ranging from Ø32 mm to Ø630 mm, available in lengths of 6 m, 12 m, 13.5 m, and 16 m (straight bars), or in coils of 50 m, 100 m, and 200 m (up to 300 m depending on the diameter).

    They can be produced as:
    Single-layer pipes (black, optionally with colored stripes)

    Double-layer pipes (with a colored outer layer)

    TYPE 1 – Single-layer pipes

    Pipes can be produced in a single layer, in black color, or optionally in black with co-extruded colored stripes.

    TYPE 2 – Double-layer pipes Double-layer pipes with a dimensionally integrated colored outer layer.

  • Peštan PEHD pipes for cable protection and installation are made of PE-RT or PE 100 polyethylene.

    The ring stiffness of the pipes is very high and, depending on the diameter and pipe type, can exceed 50 kN/m2, allowing installation in areas with increased soil load — in accordance with static calculations. (Expected service life: over 50 years at 70°C.)

    These pipes are characterized by long-term thermal stability and durability.(Expected service life: over 50 years at 70°C.)

    PEHD protective and installation pipes are UV-stabilized.
    They are electrical insulators and do not contribute to flame propagation (normal flammability, class B2 according to DIN 4102-1).

    The safety factor of PEHD pipes is 1.25, and the minimum bending radius is 20d. PEHD pipes have high abrasion resistance. The linear expansion coefficient for polyethylene is 1,8×10-4K-1 (0,18 mm/m °K).

    Installation of Polyethylene Pipes

    Peštan PE-RT pipes can be connected in several ways, depending on the application and pipe diameter:

    – Butt welding
    – Electrofusion welding
    – Compression fittings (up to diameter 125 mm)
    – Connection sleeves and flanges

    Butt welding and electrofusion welding are performed in accordance with DVS 2207-1 standard.
