The time it takes to put it into use after repair mainly depends on the repair method and the on-site environment. Different plans vary greatly. The specific time is as follows: 1. Quick repair solution (no need for long curing) Fiberglass pipe patcher repair: It can be put into use immediately after the installation is completed and the bolts are tightened. The repair of a single DN200 pipe only takes 15 minutes, which is suitable for emergency scenarios where work cannot be stopped. Steel casing asbestos cement joint repair: After filling and sealing is completed, it can be put into use in just 4 hours. 2. Conventional resin/adhesive repair, general conventional repair: It takes 24 to 48 hours to fully cure under normal temperature, and it can be used normally after curing. Special fiberglass repair agent: It can be completely cured in 24 hours at room temperature and can be put into use after curing to the standard. Multi-layer hand lay-up adhesive: Because it needs to be applied layer by layer and allowed to dry, it takes 2 to 7 days to fully cure and use. The specific time is greatly affected by the ambient temperature and humidity. 3. Special influencing factors: In low temperature (below 15°C) or high humidity environments, the curing time will be extended by 12 to 24 hours. ； If you need to accelerate curing, you can shorten the waiting time by heating and drying. For example, it only takes a few hours to cure after far-infrared heating.
