Compare polyurethane foam pipe insulation manufacturers

 Polyurethane foam pipe insulation manufacturers contrast, pipe insulation suitable for handling a variety of media in the range of -150 ℃ -50 ℃, it is widely used in central heating, cooling and hot oil transport and Nuanshi, cold storage, coal, petroleum , chemical industry, cold insulation works. Pipe insulation is an important factor in the impact of energy, development and application of pipe insulation more and more widespread attention around the world. After the 1970s, overseas production and application of universal attention pipe insulation, and strive to significantly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. Foreign insulation industry has a long history, and new insulation materials also are constantly emerging. Prior to 1980, the development of China pipe insulation is very slow, the few insulation plant can only produce a small amount of underground buried pipe insulation, but the Chinese insulation industry after 30 years of effort, especially after nearly 10 years of rapid development, many products from scratch, from single to diversity, from low to high quality, more and more common. Polyurethane material is currently the most commonly used insulation material. Rigid polyurethane has many excellent properties, widely used in Europe and America in the field of thermal insulation. Insulation materials in Europe and other developed countries, about 49 percent of the polyurethane material, while the proportion in China is still less than 20%. Thus, polyurethane pipe insulation material in China there is still much room for development. Pipe insulation is a way to raise the temperature of the warm pipe, in people's daily lives are often used, it has been widely accepted and used to make. Widespread use and laying pipe insulation construction, decoration and pipes, it is possible to ensure the normal and smooth well pipe. Although the pipe insulation has been the widespread use within, but its composition, insulation principle and other advantages, many people are not very clear, following brief composition and advantages of pipe insulation, pipe insulation so that we can have a fuller understanding. Closed-cell polyurethane foam rate of about 92%. Low thermal conductivity and low water absorption, together with insulation and a waterproof good performance of high-density polyethylene or fiberglass protective shell, has changed the traditional trench laying heating pipes status "wearing wet jacket", greatly reducing the heating pipes overall heat loss, heat 2% net heat loss, less than 10% of international standards.
