This production line is designed for manufacturing HDPE spiral wound drainage pipes with a diameter range of 300-1200mm. These pipes are widely used in municipal sewerage and drainage systems, gradually replacing traditional materials such as cement pipes and cast iron pipes.

The advantages of these pipes include low installation cost, easy operation, convenient connection, and economical construction, making them highly promising in the market.

Urban drainage systems
Stormwater and sewage separation projects
Industrial wastewater discharge
Tunnel drainage
Agricultural irrigation systems
