PE short pipe replacement technology
Process characteristics: It belongs to non excavation repair technology, which uses existing inspection wells and damaged pipelines to pull PE or fiberglass short pipes into the damaged pipeline through hydraulic expansion head anchor rods. The static pressure expansion method is used to repair and update the original pipeline.
Easy construction, small footprint, fast speed, short construction period, low cost, safe and reliable.
Common PE short pipe replacement specifications (as follows)
①. Replace the original pipe diameter of DN300mm with a PE short pipe diameter of DN280mm.
②. Replace the original pipe diameter of DN400mm with a PE short pipe diameter of DN355mm.
③. Replace the original pipe diameter of DN500mm with a PE short pipe diameter of DN450mm.
④. Replace the original pipe diameter of DN600mm with a PE short pipe diameter of DN560mm.
