Polyurethane insulation pipes are mainly installed in underground or overhead places to provide insulation during daily use. What is its development process? Below, the editor will take you to learn about its historical development stages.

The initial stage of polyurethane foam insulation pipe was in 1980. The performance of polyurethane insulation pipe exceeded that of glass wool pipe in Europe. Before the 1980s, the development of polyurethane foam insulation pipes in China was quite slow. The penetration rate of urban pipes was low, only a few percent, and there was basically no use in rural areas. Therefore, the development of polyurethane foam insulation pipe in this period is still in its infancy.

In the development stage of polyurethane foam, from 1980 to 1995, people began to realize the durability and reliability of polyurethane insulation pipe. After 1980, with the deepening of reform and opening up, China's market economy began to rise. The advanced technology of Chinese polyurethane foam has promoted the development of Chinese market. Through the research and development of insulation industry, China's insulation pipes have undergone fundamental changes, and their functions have been greatly improved.

Polyurethane insulation pipes have achieved a breakthrough stage since 1995, so now their development in China is becoming more and more perfect, with increasingly complete specifications and products.

The medium it transports is usually below 120 ℃, and some of the hot water in the transport medium is below 140 ℃. After improvement by technicians, polyurethane insulation pipes have been used to form some high-temperature resistant isocyanate structures, achieving a high temperature resistance of 150, which meets the normal use in the region. A small portion of the heat transfer pipeline network is transported before heat exchange, with a transport medium of 350 ℃.

The increasing popularity and use of polyurethane insulation pipes have led many insulation pipe manufacturers to offer compatible products but cannot guarantee quality. Therefore, when choosing them, we need to carefully consider and inspect the quality before making a decision.
