110 communication corrugated pipes are mainly used in engineering, construction engineering, electrical and telecommunication engineering, railways, highway communication, industry, agriculture, road engineering, and mining sites. HDPE double-wall corrugated pipes are primarily made from HDPE (polyethylene) as the raw material, suitable for a wide temperature range (+60°C to -20°C). Due to their structure, the outer wall has raised corrugations while the inner wall is smooth, offering advantages such as light weight, good impact resistance, strong corrosion resistance, and resistance to both cold and heat. Both ends of the pipe have sealing rubber rings embedded in the wave troughs, providing excellent waterproof sealing. This product is widely used for laying communication lines, electrical wires, and cables. Double-wall corrugated pipes, made from high-density polyethylene, are a new type of lightweight pipe with characteristics such as light weight, high pressure resistance, good flexibility, fast construction, and long service life. Their excellent pipe wall structure design reduces costs compared to pipes of other structures. Moreover, due to convenient and reliable connections, they are widely used in many regions, largely replacing concrete and cast iron pipes.

Strong resistance to external pressure
The outer wall features a ring-shaped corrugated structure, which enhances the pipe's ring stiffness and thus improves its resistance to soil loads. In this aspect, HDPE double-wall corrugated pipes have a significant advantage over other types of pipes.
