Vital Energi traditional steel pre-insulated pipes are suitable for district heating and district cooling applications. They are constructed of a carbon steel service pipe, polyurethane (PUR) foam insulation and High Density Polyethylene (HDPE) outer casing. The traditional single steel pipe system is a bonded system manufactured according to BS EN253, this means the steel carrier pipe, insulation and outer casing are moulded together to form a solid unit. Thus, the expansion movements of the steel carrier pipe will be transferred to the outer casing via the foam insulation.
Vital Energi Traditional steel pre-insulated pipes are available in three insulation thicknesses Series 1, 2 and 3 and are manufactured in 6m and 12m and 16m lengths as standard. The pipes are supplied with two copper wires embedded in the polyurethane (PUR) insulation; these wires are used to identify any leaks in the system.
The polyurethane (PUR) insulation has a guaranteed lambda value of 0.027 W/mK.
Vital Energi Traditional steel pre-insulated pipes are available in carrier pipe sizes from O/D 26.9mm to 1219mm.
