The replacement speed is fast, allowing for a reduction in construction time! We will replace the existing aging pipes with new ones without excavation.
"Expanded" is a header (crusher) that crushes aging existing pipes. Depending on the applicable pipe diameter, it is a compact crusher that can start and reach from a shaft (φ1500mm). Unlike lining methods, there is no loss of effective diameter for the installation of new pipes, resulting in no loss of flow cross-section. 【Features】 ■ Applicable diameters range from nominal sizes 200 to 600mm ■ The replaceable new pipes are push pipes - Ceramic pipes, fume pipes, steel pipes, polyethylene pipes, ductile pipes, etc. ■ Depending on conditions, it is also possible to increase the diameter by one size ■ Safe construction without excavation, allowing for fast renewal (replacement) speed and shortened construction periods *For more details, please refer to the PDF materials or feel free to contact us.
