CIPP - Thermal

A new structural pipe inside the existing one, installed without excavation and cured with steam or hot water. Ideal for large diameters and long runs. ASTM F-1216 certified.

CIPP-Thermal (Cured-in-Place Pipe with thermal curing) is the most proven and mature version of trenchless CIPP rehabilitation. It renews existing pipelines from the inside — without excavation — by installing a liner impregnated with thermoset resin that cures through steam or hot water circulated inside the liner.

How it works:

The process begins with a CCTV inspection to diagnose the pipeline's condition. The resin-impregnated liner is then introduced through an existing manhole, either by inversion (using air or water pressure) or by pull-in-place method. Once in position, steam or hot water is circulated through the liner, activating the resin curing process and producing a new structural pipe fully integrated into the existing one.

Why CIPP-Thermal:

It is the longest-proven CIPP technology in the world, with decades of validation in municipal and industrial projects. It is particularly suited for large diameters, long runs, and applications where UV curing is not optimal. The cured liner complies with ASTM F-1216 and ASTM F-2019 standards, with an estimated service life of over 50 years.

At TUBEPOL, we combine both curing technologies — UV and thermal — to deliver the optimal solution based on each project's diameter, length, and field conditions.
