A Guide to Pipe Lining Curing Processes

Cured-in-place pipe (CIPP) lining is a modern solution for repairing damaged pipes without extensive digging. This trenchless technology involves creating a new pipe within the existing one, effectively sealing any leaks or cracks. A critical step in trenchless pipe lining in Charlotte, NC is curing the new liner to ensure it hardens properly and forms a durable, long-lasting pipe. Next Level Pipe Lining highlights the various curing methods used in this process and what factors affect their effectiveness.

Steam Curing

Steam curing is the most commonly used curing option for CIPP pipe lining. This involves using steam to heat the liner, which activates the resin and initiates the curing process. Steam curing is beneficial in situations where time is of the essence, as it significantly reduces the curing time compared to other methods. However, it requires careful temperature control to avoid overheating and potential damage to the pipe or resin.

Hot Water Curing

Similar to steam curing, this method involves heating the liner to activate the resin. But instead of using steam, hot water is circulated through the pipeline, ensuring even heat distribution. Hot water curing is a slower process compared to steam curing, but it offers more control over the curing temperature. Pipe lining companies often use hot water curing for large-diameter pipes and projects with specific temperature requirements.

Ambient Curing

Ambient curing, as the name suggests, involves allowing the liner to cure at room temperature without any external heat source. One advantage of this method is its simplicity; it requires minimal equipment and can be done on-site without any specialized tools. However, this typically results in a longer curing time, which may not be feasible for cast iron pipe lining projects with tight deadlines.

UV Light Curing

UV light curing is a newer technology that utilizes ultraviolet light to cure the liner. A resin with photoinitiators is used, and once exposed to UV light, it quickly hardens and forms a durable pipe. This method offers the fastest curing time compared to other options, making it ideal for emergency repairs. Additionally, UV light is a clean and environmentally friendly alternative that does not produce any hazardous by-products.
