Can PE pipe be buried beneath the Earth?Can PE pipe be buried beneath the Earth?Rather, it is felt that a comprehensive presentation of these design and installation principles may assist the engineer or designer in utilizing PE pipe in a range of applications that require that it be buried beneath the earth. 265-303dd 265 1/16/09 9:58:31 AM Chapter 7 Underground Installation of PE Piping 266Chapter 7 - Underground Installation of PE Piping Can PE pipe be laid in heterogeneous ground?Can PE pipe be laid in heterogeneous ground?PE pipes having a protective outer sheath (multi-layer) may be laid in heterogeneous ground without sand bedding thus allowing a wide range of excavated materials to be re-used.Bedding requirements for PE pipe Pipe Bedding and Backfill

The thickness of this layer depends on the pipe diameter:* For pipe with a diameter of 300 to 1350 mm (12 to 54 in). the thickness of the bedding is 100 mm (4 in). For pipe diameters larger than 1350 nun (54 in). the thickness of the bedding is 150 mm (6 in). Pipe is laid directly on the bedding.

What is flexibility in PE pipes?What is flexibility in PE pipes?Flexible pipes can deflect up to their allowable deflection limit without damage. Most PE pipes can withstand large amounts of deflection without damage but for practical purposes PE pipes are limited to 7.5% deflection or less depending on the DR and application. For PE pipes, flexibility is directly proportional to the Dimension Ratio (DR).Chapter 7 - Underground Installation of PE Piping608 Storm Sewer

For polyethylene and polypropylene pipe, conform to ASTM D2321 pe pipe bedding in estonia or shape the bed under the pipe. (4) If rock, hardpan, or fragmented material exists, excavate the trench below the pipe to a depth equal to 1/2 inch per foot of proposed embankment above the top of the pipe, but not less than 6 inches.

For excavations in rock, 150 mm bedding depth may be required. Where fittings or mechanical joints are used, the bedding material may need to be excavated to prevent point loading.PE Below Ground Installation - Vinidex Pty Ltd

It is flexible, comes in coils and is used for most "pull-in" type systems. Where pipe is installed in trenches, it is harder to lay flat in the trench than PVC pipe. Since it comes in coils, PE pipe takes fewer fittings to lay.

DESIGN AND SELECTION OF PLASTIC PRESSURE PIPE

The reduction in working pressure of a PVC pipe below its pressure class increases as the flow velocity increases. At 7.5 fps the working pressure of the PVC pipe is less than that of the PE pipe.

Large diameter (450 mm and above) PE pipes require the overlay materials to be carried to a cover of 300mm above the top of the PE pipes. Detector tapes, or marker strips, should be laid on top of the overlay once a layer of 150mm soil has been compacted. Vibrating plate compactors must not be used until there is a 300mm layer of overlay soil over the crown of the PE pipe.
