Different Curing Methods Used in Trenchless Pipe Lining

The repair and rehabilitation of existing pipelines without extensive digging has become possible through trenchless technology. An important phase of trenchless pipe lining in Bellevue, WA is the curing process, which ensures that the lining material adheres to the host pipe and forms a strong bond. Sewer Solutions NW shares the various curing methods used by pipe lining companies, highlighting their unique features and applications.

Steam Curing

Steam curing is a widely used method in trenchless sewer repair. This process uses high-pressure steam to accelerate the curing of the resin within the lining material. The steam is introduced into the liner through a series of small vents, allowing it to circulate and evenly heat the entire pipe section. This option is favored for its speed, as it can significantly reduce the curing time from days to hours.

Hot Water Curing

This is quite similar to steam curing but uses hot water instead to heat the resin. The temperature of the water is carefully controlled and can range from 140 to 180 degrees Fahrenheit. Hot water curing is preferred for its ability to cure longer sections of pipe at once, making it more efficient for larger projects.

UV Light Curing

This is a newer method that uses UV light to harden the resin in the liner. This method is highly effective and provides a rapid curing process, often completed within minutes. UV light curing is ideal for trenchless pipe repair projects requiring quick turnaround times and is commonly used in pipes with smaller diameters. Additionally, this method tends to result in less wrinkling and shrinkage of the liner material.

Ambient Curing

Ambient curing relies on natural temperature and humidity to cure the resin over time. This is often employed for smaller or less complex trenchless pipe replacement or repairs. The primary advantage of ambient curing is its simplicity, as it does not require additional equipment to induce the curing process.
