Designed to meet the rigorous demands of various applications, Dura-Line's Smooth Wall HDPE Innerduct Conduit demonstrates versatility and reliability in both industrial and telecommunications sectors. This high-density polyethylene conduit is particularly well-suited for wind farm operations and municipal needs, allowing for installation even in cold climates. Its co-extruded SILICORE® ULF lining enhances performance by enabling longer cable pulls and facilitating higher speed jetting, while the flexible design allows for gradual bends without the need for specialized tools. Offering continuous lengths from long reels, this conduit minimizes costs associated with joins and can function effectively as both an outer conduit and innerduct. The smooth inner and outer wall construction further aids in installation methods ranging from direct burial to horizontal directional drilling, ensuring compatibility with various project requirements. Available in multiple colors and sizes, including a typical 4" SDR 13.5 option, this conduit meets ASTM and NEMA standards, making it a reliable choice for any underground application.
