THE GEORGE FISCHER RANGE OF PRODUCTS:

  • keyboard_arrow_downPlastic Pipe Sizes:

     

    Plastic pipe dimensions are, by convention, specified by the outside diameter, usually denoted by e. This may be supplemented by stating the nominal inside diameter or DN. Sometimes the pipe wall thickness is specified by the SDR or Standard Dimension Ratio.

     

    SDR = d divided by e.

    Where d = the outside diameter (mm)

    Where e = the pipe wall thickness (mm)

  • keyboard_arrow_downWhat Pipe Size?

     

    The pipe size can be calculated as follows:

    di = 18.8 √Q1 ÷  v

    Where:

    di = Inside pipe diameter (mm)

    Q1 = Flowrate in m3/h

    v = Flow velocity, usually 0.5 to 1.0 m/s for suction lines

    OR

    1.0 to 3.0 m/s for discharge lines.

  • keyboard_arrow_downPressure loss in straight pipe:

     

    A rough calculation of pressure loss in straight length plastic pipe can be done using,

    Δ Pr = λ × (L ÷ di) × (ρ ÷ 2.102) × v2

     

    Where:

    Δ Pr = Pressure loss (bar)

    λ = Pipe friction factor

    L = Length of straight pipe (m)

    di = Inside pipe diameter

    ρ = Liquid density (kg/m3)

    v = Flow velocity (m/s)

     

    For smooth bore plastic pipe: λ = 0.02
