Insulated pipe lines

Pipe lines for installation in conditions subject to frost

Purpose-made insulated pipes made of PEHD can be used for services that must be protected against hot or cold temperatures. Both the fluid pipe and conduit consist of JANSEN bianco drainage pipes. The gap between inner and outer pipe is filled with FCKW-free polyurethane foam. Fittings and customer-specific constructions can be manufactured using the diverse PE processing options. If required, an additional trace heating system can be integrated.

Advantages
