Heat exchanger intended for CIPP (cured-in-place pipe)

How to avoid hot water boiler fouling problem in CIPP (cured-in-place pipe)

SACOME receives a request from a company specialized in in-situ pipe repair using the CIPP technology —cured-in-place pipe. This method allows the rehabilitation of water, gas and chemical lines that require repair or sealing, by introducing a flexible tube impregnated with resin, without the need for excavation or earthworks.

This company installs the system in trucks. The company has a boiler to generate the needed hot water for the curing process. The main drawback is that the boiler and its circuit get dirty with the resin used, which means power loss and continuous cleaning work.

SACOME’s engineers design two I-TFM-I heat exchangers with corrugated tubes, one for a water volume of 30 m³, and the other one for a water volume of 60 m³, so that the hot water circuit becomes independent from the dirty water circuit. Therefore, the existing fouling problem is solved.
