Pre-insulated Pipes


Foam for pipes and special parts is made with foamed cyclopenthane, which provides enhanced thermal insulation and reduced dispersion, and hence considerable energy saving.

Zinchitalia Spa. makes pre-insulated pipes in accordance with the applicable standards for pre-insulated pipes for district heating – EN 253, EN 448, EN 488 and EN 489.
The family of Tecnotherm products ranges from ND 15, with a 90 mm HDPE outer sheath, to ND 500, with a 710 mm or 800 mm HDPE outer sheath, in commercial lengths of 6 and 12 metres.
Service pipes can be made of various materials to suit the customer’s requirements – carbon steel, stainless steel, galvanised steel, copper, polyethylene (PE) and polybutylene (PB).
The polyurethane foam used (PUR), a high-pressure mix of polyol and isocyanate, provides effective insulation through time and is entirely CFC-free, in compliance with today’s rigorous standards.

The outer protective sheathing is made of HDPE in accordance with EN 253. Another option is galvanised spiral sheet-metal for outdoor applications.
Tecnotherm pre-insulated piping is monobloc, a fundamental requirement for correct absorption of thermal dilation, thereby guaranteeing long life for district heating networks.
All our pipes and accessories for district heating networks can be supplied with various kinds of alarm system for locating and monitoring problems affecting the network. Nordico or Brandes systems can be used during the production stage.
