Introduction
Geothermal pipes transfer heat from the ground into a building to provide space heating and preheat domestic hot water. Geothermal heat exchange is a clean energy method for heating and cooling commercial and residential buildings. This technology has been proven effective and widely applied for decades.
In simplest terms, HDPE pipes are buried underground, enabling energy transfer between the fluid inside the pipes and the earth. The fluid in the pipes is warmed in winter and cooled in summer. The entire system consists of buried HDPE pipes, a heat pump, and an air distribution system.

Feature
Benefits of (High Density Polyethylene) Perforated Permeable Pipe
· The pore size is small, and the pipe surface porosity exceeds 85%, delivering excellent drainage performance. It enables omnidirectional water permeability with superior water seepage capacity.
· High compressive and tensile strength, and an extended service life.
· Excellent corrosion resistance and microbial erosion resistance.
· Lightweight, with fewer joints and convenient installation.
· Made from PE raw material, it features high flexibility, good soil compatibility, and is non-toxic and safe.
· Antioxidants and carbon black are added during the production process, resulting in enhanced UV resistance and anti-aging performance.
· High ring stiffness. Verified by professional testing institutions, its ring stiffness meets industry high standards, and the pipe is easy to connect. It is typically available as black PE pipe or gray PVC pipe.
· Laser-marked on the pipe surface for long-term traceability.
· Can be quickly cut to the required length and joined via heat fusion or mechanical fittings, reducing labor costs and shortening installation periods.

Application
Agricultural Drainage
Perforated HDPE pipes are widely applied in agricultural drainage to control waterlogging and enhance soil drainage capacity. Installed in farmlands, orchards and other agricultural areas, these pipes effectively prevent crop damage and promote healthy plant growth.
Subsurface Drainage
Perforated HDPE pipes also serve in subsurface drainage systems, removing excess water to prevent flooding. They are suitable for installation in residential, commercial and industrial zones, protecting buildings, roads and other infrastructure from water-induced damage.
Landfills
In landfill projects, perforated HDPE pipes are used to collect and transport leachate for subsequent treatment. The perforations allow leachate to enter the pipes, avoiding contamination of surrounding soil and groundwater.
Mining and Oil Extraction
Perforated HDPE pipes are utilized in mining and oil extraction operations for conveying water and other fluids. They are applicable to both above-ground and underground scenarios and can be customized to meet specific project requirements.
