Shandong Hipper Pipe Industry Science and Technology: Common Problems and Solutions of Polyurethane Thermal Insulation Pipe

1. During the construction in autumn and summer, the starting speed of polyurethane insulation pipeline becomes slower because of the low or sudden decrease of air temperature, which not only affects the construction process, but also affects the quality of the whole project. The treatment method is that the ambient temperature and black material temperature can be improved together. Experience has proved that the construction can be stopped smoothly if the temperature of black material is improved to 30-60 C and the ambient temperature is increased to 20-30 C.

2. Contrary to the first achievement, the starting speed of thermal insulation pipeline is fast. This phenomenon usually appears in the spring and summer when the temperature is higher or in the middle of the night construction site, which is the result of the sudden decrease of temperature. The treatment is to cool the black material with cold water, perhaps by putting the pipes outdoors a day earlier to stop natural cooling and prevent direct sunshine.

3. is the polyurethane insulation pipe foam strength is small and soft, which is caused by the imbalance of color materials. Workers can appropriately increase the proportion of black materials, according to 1:1-1.05, but also pay attention to the proportion of black materials can not be increased too much, otherwise the foam will become brittle, and affect the function of pipes.
