Key Features of HUALIN 3 Inch Hdpe Pipe
3 inch HDPE pipes are lightweight, high-strength, and corrosion-resistant, and can withstand the erosion of a variety of chemicals. At the same time, the HDPE material gives it excellent flexibility and impact resistance, and can be used stably in a wide temperature range, and is not easily damaged by external pressure or environmental changes. In addition, 3-inch HDPE pipes can be connected by hot melting or electric melting, and the interface is firm and well sealed, which effectively prevents liquid leakage and improves the safety and reliability of the entire pipeline system.

3 inch HDPE Pipe Considerations
During the connection process, the temperature of the heating plate should be kept at 210±10℃ for hot-melt connection, the voltage should be kept stable at 200–220V, and the interface alignment deviation should be ≤10% and there should be no oil residue. Before the electric fusion connection, the impurities in the socket should be removed, the power-on voltage should be 35–40V, and the time should be 30–40 minutes15. In terms of the installation environment, electric fusion connection is preferred in narrow spaces. In the high temperature environment in summer, serpentine laying is recommended to release thermal stress. In the installation of sewer pipes, the slope should be reasonable and a water return bend should be set to avoid water accumulation and odor.

HUALIN 3 Inch Hdpe Pipe Applications Explored


HUALIN 2 Inch Hdpe Pipe are widely used in various industries and play an important role in multiple scenarios. Some common applications include:
1.Municipal water supply system: In the water supply network of cities or towns, 3-inch HDPE pipe can be used to distribute and transmit drinking water. It has good hygienic properties, corrosion resistance and long service life, and is suitable for underground laying.
2.Drainage and sewage systems: Whether it is a new construction or renovation project, HDPE pipes are widely used in sewage discharge and rainwater collection systems due to their excellent chemical corrosion resistance, wear resistance and sealing properties.
3.Industrial Applications: In chemical plants or other occasions where corrosive substances need to be handled, HDPE pipes can be used to transport various acid and alkali solutions and other chemicals because they have strong resistance to these substances.
4.Communication cable protection: As a protective casing for communication cables, HDPE pipe provides physical protection and prevents moisture and other harmful substances in the soil from corroding the cables.
5.Agricultural irrigation: For agricultural water pipe systems, such as sprinkler and drip irrigation systems, 3-inch HDPE pipes can provide a larger flow rate and can withstand a certain amount of external pressure and impact, and adapt to complex terrain conditions.
