Advantages of 75mm HDPE Air Duct
Enhanced durability and longevity: 75mm hdpe air duct are synonymous with strength and resilience. Their unique design combined with the robust material significantly extends the lifespan of the pipeline. This reduces the need for frequent replacements and the overall cost of ownership.
Superior corrosion resistance: Corrosion can compromise the integrity of a piping system, leading to leaks and environmental damage. Hdpe pipes are inherently resistant to rust and other forms of corrosion, ensuring a secure and long-lasting piping solution.
Excellent chemical resistance: These pipes withstand exposure to a wide range of chemicals, making them ideal for industrial applications where harsh substances are common. The chemical resistance of hdpe conserves the quality of the conveyed materials and the surrounding environment.
High flexibility and impact strength: 75mm hdpe air duct can withstand ground movements and pressure fluctuations without sustaining damage. This feature is particularly beneficial in earthquake-prone areas or where ground conditions are unstable.
Easy installation and maintenance: The lightweight nature of 75mm hdpe air duct simplifies handling and installation processes. Moreover, their joint integrity and low maintenance nature contribute to long-term savings.

Made from high-density polyethylene (HDPE) raw material, HDPE, as a food grade material, has excellent low-temperature resistance (operating temperature is -100℃~70℃), and can be used with confidence in low temperature environments in the north. Good chemical stability, resistant to most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation, and longer service life.
The inner wall is treated with anti-static and demagnetizing treatment, with less wind resistance and no residual dust retention. 99.94%silver ions Antibacterial and mold resistant rate, achieving a cleaning free system, ensuring that the pipeline system throughout the entire decoration space will not have secondary pollution problems. The anti-aging treatment of the whole pipeline has a longer service life.
Application of 75mm HDPE Air Duct
Residential ventilation:
Ldeal for single-family homes, villas, and apartments, allowing for quick, discreet installation in concrete structures or compact ceiling spaces.
Specific room ventilation:
Used for kitchens, bathrooms, home offices, and living areas to maintain optimal air quality.
Heat recovery systems:
Plays a crucial role in mechanical ventilation with heat recovery (mvhr) systems, offering high performance and ease of installation.
Commercial hvac systems:
Suitable for office buildings, schools, hospitals, and shopping malls, particularly where fresh air intake and stale air exhaust are needed with minimal visual impact.
Production Process of 75mm HDPE Air Duct
Raw material preparation and drying: The first step in the hdpe pipe production process is selecting the high-quality raw materials. The material must meet stringent quality standards to ensure the resulting pipes have the desired properties, such as high tensile strength, chemical resistance, and longevity.
Plastic & extrusion: The extrusion process is the heart of hdpe pipe production. Raw materials enter the extruder from the hopper, and are transported, compressed, melted and homogenized, and then transforming it into a continuous hdpe pipe profile.
Cooling and sizing: After extrusion, the newly formed hdpe pipe passes through a cooling chamber. This chamber utilizes a cooling medium, such as water or air, let the high-temperature hdpe pipe is rapidly cooled, solidifying its shape.
B: Once the hdpe pipes are cooled and sized, they undergo marking and printing procedures. Information such as manufacturer’s name, pipe size, and relevant standards are imprinted on the pipe surface using automated printing machines.
Pipe cutting: Under the control of the meter wheel, the fixed-length cutting of the pipe is completed by the planetary cutting machine.
Quality control and testing: Ensuring the highest quality standards is paramount in hdpe pipe production. Comprehensive quality control measures are implemented at various stages of the manufacturing process.
Coiling and packaging: The packaging is designed to safeguard the pipes from external elements and ensure their safe delivery to the end-users.
