Pre-insulated steel pipes

The offer of pre-insulated steel pipes includes a complete range of pipes, fittings and pre-insulated fittings for the transmission of heating medium and hot utility water. Pipes are supplied in a wide range of carrier pipe diameters – in the case of a single pipe from DN 20 mm to DN 1200 mm, and in the case of a double pipe from DN 20 mm to DN 200 mm. For underground heating networks, a PEHD high-density polyethylene pipe is used as a casing pipe; for overhead heating networks, pipes are made in casing made of rolled sheets (SPIRO type). Pre-insulated pipes can be equipped with a polyurethane insulation moisture detection system.

• Pipes manufactured in accordance with PN-EN 253, PN-EN 448, PN EN 489, PN-EN 13941,

• A wide range of pipe operating temperatures up to max. + 152 ° C,

• Complex construction of pipes,

• Ready pre-insulated elements (elbows, tees, valves),

• Leak detection systems (impulse or brandes),

• Low PUR foam insulation coefficient λ = max. 0.029 (W / mK),

• Long installation life

Double pre-insulated steel pipe

Pipes intended for transmission of heating medium and hot domestic water.

The pipes are manufactured in lengths of 6 and 12 meters. Pre-insulated pipes can be equipped with a polyurethane insulation moisture detection system. The standard solution is the impulse leak detection system. On special request, the BRANDES system, HDW system or other system can also be used, according to individual customer needs.
