We would like to introduce the fiberglass composite high-strength CIPP pipe rehabilitation method.
The "K-2 Method" involves impregnating a heat-curing resin into a K2 liner, which is covered on both the inner and outer surfaces with a plastic film. This liner is then pulled into the pipeline, where liquid pressure is applied within the lining material, adhering it to the pipeline wall. The lining material is heated using hot water or a hot water shower, curing the heat-curing resin and forming a CIPP (Cured-In-Place Pipe) within the pipeline. After curing, the plastic film on the inner surface is peeled away, resulting in a pipe rehabilitation method. 【Application Range】 ○ Main sewer pipes: φ200 to φ600mm ○ Sewer connection pipes: φ150 to φ200mm ○ Installation length → Main pipes: φ200 to φ350mm, maximum 120m → Main pipes: φ400 to φ600mm, maximum 80m → Connection pipes: maximum 13m For more details, please contact us or download the catalog.

Company information
Kyosen Civil Technology Co., Ltd. is a manufacturer and seller of the pipe rehabilitation system "K-2 Method." The "K-2 Method" involves impregnating a K2 liner, which has a tubular resin absorption material covered with a plastic film on both the inner and outer surfaces, with thermosetting resin. This liner is then pulled and inserted into the pipeline, where liquid pressure is applied to the lining material, adhering it to the pipeline wall. The lining material is heated using hot water or a hot water shower, curing the thermosetting resin and forming a CIPP (Cured-In-Place Pipe) within the pipeline. After curing, the plastic film on the inner surface is peeled away, completing the pipe rehabilitation process.
