Hdpe Pipe-Coil Pipe
The medium size of the 3/4 Inch Hdpe Pipe, with an outer diameter of approximately 25mm, makes it easy to install and construct. It is widely used in domestic water supply, small irrigation systems, and industrial fluid transportation. Suitable for medium transport from minus 40 degrees Celsius to 50 degrees Celsius, the tube body is black or blue and accepts customized requirements.

Product features:

Easy to install: Small diameter HDPE pipe due to small diameter, lightweight, easy to manual handling and install.

Reliable connection: An electric fusion connection can be used to ensure the tightness and reliability of the pipeline connection.

Corrosion resistance: can resist a variety of chemical substances and environmental factors of erosion, suitable for a variety of fluid transport.

Temperature resistance: can be used in a certain temperature range, suitable for indoor and outdoor environments.

Smooth inner wall: reduce fluid flow resistance, improve transportation efficiency, and reduce energy consumption.

Flexibility: Good flexibility allows the pipe to adapt to small changes in the ground, reducing the risk of rupture.

Pressure resistance: Depending on the wall thickness and design, the HDPE tube can withstand a certain working pressure.

Long life: With proper use and maintenance, the service life of HDPE tubes can be very long.

Low maintenance costs: Low maintenance costs due to its chemical resistance and wear resistance.

Large flow rate: Because the inner wall is smooth, the flow rate of the HDPE pipe under the same diameter is larger than that of the rough pipe.

Easy to process: Small-caliber HDPE tubes are easy to cut and bend, making them suitable for custom installation
