Quick-lock is used for CIPP patch spot repair produced by DAO

The drainage pipe, sewage pipe, and sewage pipe in the city are rolled by the ground, resulting in changes in the stratum, which will affect the quality of underground pipes. Some pipelines are damaged internally, and some are broken with obvious cracks. Water flows out of the cracks, and even serious pipelines are subject to external pressure, resulting in a large number of holes.

In this case, the inner wall of the trenchless pipeline can be used for repair. There are no good methods and materials to repair in the market. There is a material 304 stainless steel quick lock. This kind of material can be effectively installed inside the pipeline to play a repair role, and it is a material with a good sealing effect. During the normal operation of the pipeline, the pipeline can be operated with water under the condition of sewage, and the damaged and internal parts of the pipeline can be repaired with a quick lock to achieve the effect of water stop and sealing.
