Flexalen PU pre-insulated pipes are specially designed for medium to large heating networks where flexibility is required in combination with the highest insulation class.
Flexalen PU
Flexalen pre-insulated pipes
Flexalen PU pre-insulated pipe consists of:
- Service pipe made of polybutene (PB-1): a flexible polyolefin material for fast and reliable installation and a guaranteed service life. It is best in class in terms of pressure and temperature resistance.
- Bonded continuous foamed polyurethane (PUR) insulation with excellent insulation values.
- Corrugated Low Density Polyethylene (LDPE) casing pipe for coiled tubing, for maximum flexibility and protection against external damage.
Flexalen PU SL pre-insulated pipe consists of:
- Service pipe made of polybutene (PB-1): a flexible polyolefin material for fast and reliable installation and a guaranteed service life. It is best in class in terms of pressure and temperature resistance.
- Bonded polyurethane (PUR) insulation with excellent insulation values.
- Smooth High Density Polyethylene (HDPE) casing pipe for straight pipes, to protect against external damage.
Flexalen PU, the highest insulation class for main pipelines, can easily be combined with Flexalen 600, the most flexible house connection. It is safe and reliable thanks to the homogeneous welding and high pressure capacity of 8 bar at 95 °C.
We offer support with integrated network design, calculation tools, training and on-site support.
