Recommendations for processing:
The key conditions for the qualitative filling of pipes with polyurethane foam are: compliance with the accuracy of dosing and temperature conditions of the PU-system components' processing regime; sufficient mass of the poured PU-system portion; proper preparation and appropriate temperature of the metal pipes' surface.
Temperature of Components: (18 - 22) °C
Temperature of pipes: (20 – 30) °C.
Prior to pouring the system, the surface of metal pipes gets cleaned off oil, scale and rust. PU-system components are processed by means of high- or low-pressure filling machines. Technical documentation for the equipment and the process of obtaining finished products are the guidelines for the system processing.
