Factory insulated, flexible plastic pipe system, with fiber-reinforced carrier pipe
For heating and drinking water with factory-applied thermal insulation, with one or two medium pipes, in rolls.
Plastic pipe made of cross-linked POLYETHYLENE (PEX) with at least 75% degree of cross-linking, tested, internally and externally monitored according to standard.
Medium pipe for the heating area with additionally applied, coloured oxygen diffusion barrier layer of ethylene/vinyl alcohol (EVOH).
|Max. Continuous operating temperature:||80°C|
|Max. Operating temperature:||95°C floating|
|Thermal conductivity:||0,021 W/mK|
|Operating pressure:||10 bar|
|Carrier pipe:||cross-linked polyethylene (PE-Xa) reinforced with aramid fibers|
|Thermal insulation:||Polyurethane (PUR), FCKW-free|
|Jacketing:||corrugated PE-LD, seamless extrusion|
Press fittings have an additional polymer crimp sleeve between the sliding sleeve and the carrier pipe. This allows the support sleeve to be inserted directly into the pipe ends during installation without expanding. Up to size 110, standard pressing tools can be used as for PE-Xa pipes (SDR11). For larger dimensions, the KELIT pressing tool is available. The insulation of the pressing point is done with connecting sleeves.
Factory insulated molded parts
To reduce welding and assembly work on site, a wide range of factory-insulated steel moldings is available. The KELIT PEX FF press joints are welded onto the steel moldings and can be pressed directly. Joint sleeves are used to insulate joints.
Half-shells for KELIT PEX FF
Half-shells in various configurations are available for our flexible plastic pipe systems. This novel CLICK system guarantees the highest construction site quality without time-consuming gluing, screwing or shrinking with secure connection technology and best thermal insulation properties.
