By adding heat during the curing process, the cure time will decrease significantly for the installed liner or manifold. To get enough heat, hot water or steam is required.
For every ten degrees the temperature can be raised, the curing time is halved. Example: A liner in a pipeline takes about 12 hours to cure at + 10° C. If the temperature is raised to + 20° C, the heating time will be 6 hours, and so on.
Standing pipes and shorter horizontal pipes and branch pipes are best suited for heat curing with steam.
On horizontal pipes heat can be added by allowing hot water to flow through the liner after it has been installed.
