Secondary/Double Containment Systems

Industry has assessed that clean-up expenditures may far exceed the costs to install protective measures. When penalties and fines are added to the costs of cleaning up spills and leaks, it becomes obvious that industry has a legal and financial responsibility for protecting our environment. GEORGE FISCHER’S Secondary/Double Containment System provides the necessary environmental protection at a fraction of potential clean-up costs. Double containment piping systems are ideal for ensuring safety when transporting corrosive, toxic, or otherwise hazardous media.

When a leak from the primary pipeline occurs in a double containment system, the fluid is safely contained by the secondary pipe. End-users typically implement a leak detection system to alert operators when a leak has occurred.

These systems can be used in multiple applications, primarily for handling chemical and effluent water transfers.

APPLICATIONS:

Chemical process industry; life science; microelectronics; measurement & control; water treatment; ship building.

Fuseal Squared® Double Containment Corrosive Waste

Federal, state and local regulations have been created to protect our environment from industrial pollution. Protection of the soil and the groundwater table are of primary concern. The Fuseal Squared® system, with a modular design, is a...

  • 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

  • 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_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)
