HDPE smooth pipe is available in different diameters, wall thickness, physical and chemical properties. There is significant variability in commonly available materials. It is very important that it has satisfactory properties for handling, storage, installation and durability for the application. The color is normally black from a small amount of carbon in the material, to protect against degradation from ultraviolet light. The wall thickness, diameter and physical strength (Hydrostatic Design Basis) should be sufficient to initially withstand grouting pressures. In the long term it should not deteriorate or split. The requirements should be in accordance with AASHTO LRFD Bridge Construction Specifications.
All duct splices, joints and connections to anchorages should be made with couplings and connectors that produce a smooth interior duct alignment with no lips or kinks. Special duct connectors may be used in match-cast joints between precast segments and similar situations if necessary to create a continuous, air and water-tight seal. duct tape should not be used to join or repair ducts or make connections.
