As is known to all when it comes to geothermal applications, there is virtually no alternative to HDPE pipes owing to their outstanding resistance to corrosion, flexibility and long service life which set them apart from other materials . Recently, we’ve received installation pictures of high pressure( 3.5MPA) Steel Mesh Polyethylene (PE) Composite Pipe and Electro fusion fittings as below shared by one of our customers in Dumaguete, the Philippines.
The Philippines is one of the top producers of geothermal power in the world due to the country’s location in a volcanic zone, with a total installed capacity of approximately 1.9 gigawatts (GW) of geothermal power. Thanks to this, the demand for HDPE pipes has become increasingly higher these days.
They are the most common pipe material used in ground source heat exchangers .In thermal power plants, the efficient transfer of hot and cold water within cooling towers is crucial for optimal operation. A key requirement for these facilities is reliable access to water resources to fulfill their steam generation and cooling needs. However, mere availability of water sources is insufficient; maintaining the integrity of fluid quality within the piping system is equally vital.
Corrosion poses a significant threat to plant operations, while routine challenges such as pressure fluctuations, vacuum reduction, pipeline leaks, structural cracks, and maintenance requirements are common occurrences.
Polyethylene (PE) 100 pipes have emerged as an optimal solution for addressing these operational challenges, offering superior performance characteristics compared to conventional piping materials. These high-grade polyethylene pipes demonstrate exceptional suitability for fire suppression systems, cooling circuits, and potable water distribution within thermal power facilities. Their application in cooling systems presents additional benefits, particularly in preventing microbial accumulation along the interior pipe surfaces.
Here is an illustration of How geothermal power plant works step by step?
1. Hot water is pumped from deep underground through a well under high pressure.
2. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam.
3. The steam spins a turbine, which is connected to a generator that produces electricity.
During the installation of the Steel Mesh Polyethylene (PE) Composite Pipe and its connection with the Electro fusion fittings, due guidance and instruction was also provided by Puhui engineer team by virtual meeting to ensure it’s properly operated based on weather conditions of the job site. Our professional and patient technical services have been well received by customers, laying a solid foundation for long-term cooperation in the future.
