Designed for efficient and continuous production of HDPE Drainage
Pipe Corrugating Line for Sewage Systems , this line ensures
precise forming, excellent load-bearing performance, and long-term
durability. With advanced automation and stable operation, it
supports municipal sewage projects, underground drainage networks,
and large-scale infrastructure construction.
Double-wall corrugated pipes are multifunctional municipal
pipelines manufactured primarily from plastic pellets via extrusion
molding. Featuring a smooth inner wall and a corrugated external
profile (e.g., trapezoidal or arc-shaped waves), this distinctive
structural design delivers outstanding performance in ring
stiffness, pressure resistance, toughness, and corrosion and
abrasion resistance. Additionally, the pipes are lightweight, easy
to install, cost-effective in construction, and durable in service.
These pipes find extensive applications in municipal renovation,
construction projects, industrial and agricultural drainage,
agricultural water-saving irrigation, and wastewater treatment
systems. They serve as an ideal alternative to conventional pipe
materials like concrete and cast iron pipes.
Our company has launched the fourth-generation double-wall corrugated pipe, featuring:
Circumferential Continuous Sealed Pressure Water-Cooling Molding
Technology
Fully continuous, uninterrupted water cooling
Fixed water-cooling pipeline connection-no plugging/unplugging is
required when changing molds
Cooling section length: 6.3 meters
Higher efficiency with lower energy consumption
Launch year: 2013
Features of HDPE Large Diameter Hollow Wall Winding Pipe1). High Ring Stiffness
2). High Brunt Intensity and low weight
3). Good creep deformation resistance.
4). Outer pressure resistance.
5). Erosion resistance ( such as acid, alkali and salt etc. )
6). Long life of approximate 50 years. No pollution and so on.
Application of HDPE Large Diameter Hollow Wall Winding/Coil Pipe:It has been widely used for sewerage and drainage in city, it will
replace the cement pipe, cast iron pipe and other pipes. Its low
cost of assembling, easy operation, easy connection and economical
construction which makes it wide foreground and market potential.
