  2. HDPE pipe - Wikipedia

    en.wikipedia.org/wiki/HDPE_pipe

    HDPE pipe is a type of flexible plastic pipe used to transfer fluids and gases. It is often employed for replacing aging concrete or steel main pipelines . Constructed from the thermoplastic HDPE (high-density polyethylene ), it has low permeability and robust molecular bonding, making it suitable for high-pressure pipelines .

  3. High-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/High-density_polyethylene

    HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

  4. Plastic pipework - Wikipedia

    en.wikipedia.org/wiki/Plastic_pipework

    Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.

    Pipe Wall Thickness: Each thickness to be fused in production (XXVI–2310(c)). (6) Fitting Manufacturer: A change in fitting manufacturer. (7) Pipe Diameter: Each diameter to be fused in production (XXVI–2310(c)). (8) Cool-down Time: A decrease in the cool time at pressure from that qualified. (9) Fusion Voltage: A change in fusion voltage. (10)

  6. JM Eagle - Wikipedia

    en.wikipedia.org/wiki/JM_Eagle

    JM Eagle is an American corporation and a manufacturer of plastic pipe. [1] At its 22 plants in North America, the company manufactures polyvinyl chloride (PVC) and high-density polyethylene pipe for a variety of industries including utility, plumbing, electrical, natural gas, irrigation, potable water, drainage, and sewage.

  7. Cross-linked polyethylene - Wikipedia

    en.wikipedia.org/wiki/Cross-linked_polyethylene

    A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.

  8. Geomembrane - Wikipedia

    en.wikipedia.org/wiki/Geomembrane

    The US market is currently divided between HDPE, LLDPE, fPP, PVC, CSPE-R, EPDM-R and others (such as EIA-R and BGMs), and can be summarized as follows: [citation needed] (Note that Mm 2 refers to millions of square meters.) high-density polyethylene (HDPE) ~ 35% or 105 Mm 2; linear low-density polyethylene (LLDPE) ~ 25% or 75 Mm 2

  9. Polyethylene - Wikipedia

    en.wikipedia.org/wiki/Polyethylene

    The high molecular weight makes it a very tough material, but results in less efficient packing of the chains into the crystal structure as evidenced by densities of less than high-density polyethylene (for example, 0.930–0.935 g/cm 3). UHMWPE can be made through any catalyst technology, although Ziegler catalysts are most common.
