DUNAPOL® SPINPIPE is the new, original solution for insulating straight pipes: the idea is to insulate with a Polyisocyanurate (PIR) system the pipes BEFORE their installation at site.

This operation can be done by casting with a special thixotropic polyisocyanurate system or by spraying with highly reactive polyurethane/polyisocianurate chemicals and with the aid of a spraying equipment.  

In both cases, polyisocyanurate (PIR) creates a seamless insulating shell around the pipe prior to installation being at the same time in full compliance with the strictest cryogenic specification for LNG production and transport.

Polyisocyanurate (PIR) pre-insulation offers many advantages:

  • Improved quality control, with longer life cycles and reduced costs.
  • Improved scheduling. Polyisocyanurate (PIR) pre-insulation can take place indoor and independently from other steps in the construction schedule and site environmental conditions, so that pipes for any part can be pre-insulated and stored ready for use.
  • Zero health and safety accidents. By pre-insulating piping  with polyisocyanurate away from the construction site in a controlled workshop environment, insulation and cladding are applied conditions safer than those of the construction site.
  • Costs. Polyisocyanurate pre-insulation reduces the number of man-hours on-site, and reduces the duration of and need for scaffolding.
