About IBB16 ®

The IBB16® system is a hybrid hose pipe relining (without bonding with the old pipe) applicable for the rehabilitation of pressure pipes. 

The system combines two pipe liners with different properties to achieve the required criteria for the rehabilitation of a pressurized water pipe. 

The system combines the IBG UV + Steam systems to the system IBB16®. 

Where to use IBB16 ®

The system can be used in pressure pipes up to an operating pressure of 232 psi (16 bar). 

The minimum pipe diameter is: DN 150

The maximum pipe diameter is: DN 2000

System description IBB16 ®

The impregnation of the liner is performed at the liner factory. The installation of the liner takes place in one or more rehabilitation conduits defined by two or more pits or line openings.

The liner is pulled into the line using a pulley, typically with winch support and sliding protective foil, pulled onto packers and expanded using air pressure.

Curing is performed by exposure from a UV light source. The entire curing process is controlled and documented using installed sensors.

The finished product is a statically fully structural, seamless, flexible plastic pipe.
