The main feature of the polyurethane insulation pipe is that the service life can reach 30-50 years. The insulation performance of the insulation pipe is good, and the heat loss is only 25% of the traditional pipe. The long-term operation can save a lot of energy and significantly reduce the energy cost. It has strong waterproof and corrosion resistance, simple and rapid construction, and low overall cost.
The polyurethane insulation tube is made of a high-performance polyether polyol composition and a plurality of methyl polyphenyl polyisocyanates as raw materials by chemical reaction foaming. Polyurethane insulation pipe is used for indoor and outdoor various pipelines, central heating pipelines, central air conditioning pipelines, chemical, pharmaceutical and other industrial pipeline insulation and cold preservation projects.
Common problems and solutions in the construction of polyurethane insulation pipes:
1. Polyurethane insulation pipe is slow to rise. This phenomenon usually occurs in autumn and winter or in the morning because of sudden drop in temperature or low temperature. It can be solved by raising the ambient temperature and the black temperature. Generally, the temperature of the black material is raised to 30-60 ° C, and the ambient temperature is raised to 20-30 ° C.
2, polyurethane insulation pipe speed is fast This phenomenon generally occurs in the spring and summer or noon construction, because the temperature suddenly rises due to too much temperature. The black material can be cooled with cold water or placed outdoors at night to avoid direct sunlight.
