The price of the finished product of rigid foam polyurethane insulation pipes. The heating effect of rigid foam polyurethane insulation pipes. Hard foam polyurethane insulation pipes indoor and outdoor various pipes, central heating pipes, central air-conditioning pipes, chemical, pharmaceutical and other industrial pipes. Overview Polyurethane foam insulation pipe has been rapidly developed as an excellent thermal insulation material since the birth of polyurethane synthetic material in the 1930s, and its application range has become more and more extensive. It is also due to its simple construction and remarkable energy-saving and anti-corrosion effects. It is widely used in various pipelines such as heating, cooling, oil and steam. It is widely used in various pipelines such as heating, cooling, oil and steam.

Generally, the rigid foam polyurethane insulation pipe is directly poured with foaming slurry during the construction of the insulation layer of the inner pipe and the outer pipe, and the foam is formed at one time. Before pouring the slurry insulation material, the inner tube and the outer tube should be kept in good concentricity by using appropriate tools, and the sealing treatment of the lower part should be tight to prevent the slurry from leaking. According to the fluid state of the slurry and the foaming speed, the insulation layer with a smaller length can be poured upright, but for most insulation layers with a larger length, the inclined method is used to cast it so that the slurry can flow and foam. According to the formula and construction requirements, it can be injected from the upper side or from the lower part. When the pipe is long, the slurry output from the mixing head can be introduced into the lower part of the pipe gap through the pipe, and with the increase of the fluence, the pipe is gradually drawn out. But note that this method is only suitable for ordinary casing insulation below 3mm.
