PE Double-Wall Pipe PE Double-Wall Pipe

• It is a pipe made by extruding a hollow ㅁ-shaped square profile made of high density polyethylene material in a spiral direction around the axis of the pipe. It has smooth inner and outer surfaces, and the wall has an I-beam structure.

Features

• Delivery and construction to local governments and public companies
• Excellent chemical resistance (acid and alkali wastewater, salt)
• Excellent impact resistance, water tightness and water permeability
• Housing site development construction, sewage pipe construction, golf course construction
• Excellent handling and constructability
