2-wall HDPE spiral pipe DN 250

HDPE DOUBLE-WALL CORRUGATED PIPE (2L TYPE)

HDPE double-wall corrugated pipes are manufactured in compliance with TCVN 8850:2011 and TCVN 9070:2012, with diameters ranging from 150mm to 800mm.
They are widely used in:

• Urban and industrial drainage systems

• Highways, sports fields, squares, and mining areas

• Irrigation systems and aquaculture facilities

This type of pipe has become increasingly popular worldwide, gradually replacing cement, cast iron, and steel pipes due to its numerous advantages in performance and installation, such as:

• Material: Made from high-density polyethylene (HDPE) with smooth inner and outer surfaces. The walls are connected by helical ribs, which reduce friction and improve internal flow.

• Structure: The double-wall design with a hollow space between the inner and outer layers provides excellent resistance to external pressure and impact strength.

• Durability: Service life of up to 50 years when installed underground under normal conditions.

• Abrasion resistance: High resistance to wear caused by friction with impurities in wastewater.

• Chemical resistance: Excellent resistance to acids, alkalis, organic wastewater, and saline water, making it suitable for harsh environments.

• Ease of installation: Lightweight, easy to transport and install, helping reduce construction and transportation costs.

• Secure jointing system: Pipe connections are sealed with thermal welding tape and reinforced with stainless steel bands, ensuring leak-proof and watertight joints.

• Length options: Supplied in standard 10-meter lengths or customized according to customer requirements, compatible with various transport methods.
