PE gas

Peštan HDPE pipes for transportation of gas under  high-pressure are made from high quality polyethylene PE-80 and PE-100. Pipes made of polyethylene are physiological and toxicological completely safe and extremely chemically resistant. Complete range of Peštan HDPE pipes for gas has been produced according to the EN 1555. Peštan produces pipes for gas in black color with yellow longitudinal lines, and deliver them in coils of 100m and 200m, as well as in bars of 6m, 12m, 13.5m and 16m.

    PE 100 Gas

  • Production range of  Peštan HDPE pipes for transportation of gas under pressure includes  pipes produced  from the highest quality polyethylene PE-80 and PE-100 in diameters from Ø16 to Ø630.

    Also, the pipes are  available in four variants (depending on the pressure to which they are intended, and the material they are made):

    PE-80

    SDR17 – PN1

    SDR 11 – PN4

    PE-100

    SDR17 – PN6

    SDR 17.6 – PN6

    SDR 11 – PN10

    PE gas 10

    Peštan is able to offer a complete range of welded fittings manufactured in all diameters and all working pressures.

    Also, other operating pressures are available upon request.

     

  • Resistance to elevated temperature:

    At  increased exploitation temperatures (eg. Industrial use) it is necessary to correct the value using the PN -a reduction coefficient from the table:

    Connecting polyethylene pipes

    There are several ways to connect polyethylene pipes for transport of gas. The pipes can be connected in the following ways:

    1. Frontal  welding
    2. Electrofusion welding
    3. Compression fitting (diameters up to Ø125)
    4. Connecting sleeves and flanges

    Electrofusion and frontal  welding are performed according to the guidelines of DVS 2207-1

    Installation, jointing and testing of polyethylene pipeline is done according to applicable European standards and guidelines:

    EN 805

    EN 1610

    DVS 2207-1

    DVGW W 400-2 (A)

    Safety factor of HDPE gas pipes is 1.60

    Coefficient of linear expansion of polyethylene is 1,3×10-4C-1 (0.13 mm/m° C)
