PUR spacers for pre-insulated pipes
Dan-iso's PUR spacers are designed to ensure a centered and uniform foaming of pre-insulated pipes. They are placed between the service pipe and the jacket pipe and ensure the correct distance, which prevents cold bridges and unwanted ice formation. The spacers have the same thermal and mechanical properties as the rest of the PUR insulation and contribute to optimal insulation performance throughout the entire length of the pipe.
PUR spacers are typically used for district heating pipes and cold media such as liquid nitrogen, LNG, LPG and refrigerants. They can also be used between flat surfaces and mounted with adhesives or mechanical solutions – depending on the design and task.
Dan-iso offers both standard dimensions and specially designed spacers in PUR and PIR, adapted to pipe diameter, weight and insulation thickness as well as jacket pipe type. Contact us for advice and development of solutions for your specific project.
