This Appraisal is for Class A (fully structural) Nordiflow CIPP liners, Class B (semi structural with inherent ring stiffness) Nordiflow CIPP liners and Class C (semi-structural - relies on adhesion to the host pipe) Tubetex and Tubetex Combiliner CIPP liners.
The CIPP systems are suitable for rehabilitation of water pipeline materials including Ductile Iron, Steel, AC and reinforced concrete at operating pressures up PN16. Installation lengths may be up to 300m, depending on the pipe diameter.
Curing is affected by the application of steam or hot water.
