SERVICE PIPE OR PRIMARY PIPE (NIRON RANGE)

 

The service pipe for the transport of the heat transfer fluid belongs to the random Polypropylene PP-R piping range by NUPI Industrie Italiane S.p.A. It is available in single wall version and multilayer version reinforced with fiberglass (NIRON FG and NIRON CLIMA).

  • THERMAL INSULATION (PUR)

The insulation of the primary pipe is made with a rigid polyurethane foam according to EN 253 standard and is free from Freon. The coefficient of thermal conductivity is 0.027 W/mK at a medium temperature of 50°C. This excellent characteristic of the material allows to obtain high levels of thermal insulation with significantly reduced insulation layers if compared to those that would be required if other materials were to be used. In addition, due to its closed cell structure, under normal conditions of use it does not have any transformation caused by water absorption, compression, sacking, etc.

  • JACKET PIPE (HDPE)

The layer of polyurethane insulation is protected by a jacket pipe made of High Density Polyethylene (HDPE) according to EN 253.

  • PRIMARY PIPE

It is available in 6 meter long sticks for diameters from DN 25mm to DN 50mm and 6/12 meter long sticks for larger diameters (DN 63mm up to DN 355mm).

  • FITTINGS AND FITTING REPAIR KIT

The junction of the NIRON PRE-INSULATED PIPING SYSTEM can be carried out by:

  •  Polyfusion
  •  Electrofusion
  •  Butt welding
