Transportation: Transportation of chemicals: HDPE pipes can be used to carry all kinds of effluents, chemicals, waste water, sewage, spent-wash etc. HDPE being a chemically inert material can be used to carry chemicals both of acidic or alkali nature. The operational pH range varies from pH 1 to pH 14.
Transportation of solids: HDPE pipes are used for various applications including slurry transportation, sand stowing, dredging etc. Advantages of high wear resistance, corrosion resistance and low pressure loss have been demonstrated in the use of HDPE pipes.
Under-water pipe lines: HDPE pipes can be used as under-water pipe lines since they are lighter than water. This property together with its natural flexibility to accommodate itself to the available contours makes it the most suitable material for these applications.
Gas pipes: HDPE pipes are also used for gas supply. These pipes are made in yellow color, the universal color code for fuel gas lines.
^ TOP Earthquake Resistant Distribution Networks: PE pipe for fluid distribution networks, especially for critical applications like gas pipelines, has a particular advantage in earthquake susceptible areas, since the flexibility and strainability of the pipe enable it to withstand severe ground movements. This is substantiated by the Kobe earthquake studies. In this context the fusion-welded joints have proved to be of special value, as they can withstand high axial and bending loads, which otherwise cause failure of steel and ductile iron pipes.
Agricultural Applications- Borewell Delivery Lines: Since HDPE pipes are available in longer lengths, the insertion of the pump/jet is comparatively simple. The retrieval of pumps for repair is also easy.
Oil Transportation: The first HDPE pipe used for crude oil transportation was laid in 1996. Engineers from Shell, Oman have reported that a PE 100, 150mm HDPE Pipe of 27 mm wall thickness has withstood pressure of 25 kg/cm2.
Vacuum/Suction Pipelines: HDPE pipes offer the capability of resisting the collapsing forces, if a vacuum condition exists in the pipeline. Hence they may be subjected to internal pressure or vacuum and can be used in applications like Vacuum or Suction Pipelines.
Gravity Mains: For buried gravity flow lines such as sewers and OHSR (overhead surface reservoir) feeder water lines, the required wall thickness should be established in line with external stress conditions caused by earth pressure and traffic. HDPE pipes are so dimensioned that the long-term deformation does not exceed 6% after 50 years.
Pumping Mains: Any water supply distribution system consists of a network of interconnected pipes, service reservoirs and pumps, to deliver water from the source to the consumer. Water demand is highly variable by day and by season. Supply in contrast is normally constant. As a consequence, the distribution system must include storage facility and also be capable of flexible operation. Water pressures within the system are generally maintained between maximum 70m head and minimum 20m head values. This is to ensure that demand is met and that leakage due to high pressure does not happen.
