Additionally, self-supporting pipes with a nominal diameter of 900mm can also be constructed. The construction process involves pulling the rehabilitation material into the existing pipe from a manhole, attaching a dedicated tool to the upstream and downstream ends, and expanding the diameter using air pressure. The material is closely adhered to the inner surface of the existing pipe, and the inserted light-curing device irradiates light to cure the resin, forming a rehabilitation pipe with the required strength and durability. 【Features】 - Supports self-supporting pipes with nominal diameters from 150mm to 900mm - Materials can be stored for up to 3 months - Shape confirmation can be done before curing - Not affected by environmental temperature (suitable for construction in cold regions) - Construction is possible even with inflow water 【Other Features】 - Adapts to the existing pipe's shape - Can be applied to PVC pipes 【Applicable Pipe Types】 - Rigid PVC pipes, reinforced concrete, ceramic pipes, steel pipes, cast iron pipes, etc. *For more details, please refer to the related link page or feel free to contact us.
