Polyethylene sheathed polyurethane insulation steel pipe is a new type of pipe insulation material, which has excellent thermal insulation performance and durability, and is widely used in construction, chemical industry, petroleum and other fields. This article will introduce the characteristics and advantages of polyethylene sheathed polyurethane insulation steel pipe from the following aspects.
First, the composition of the material.
The polyethylene sheathed polyurethane insulation steel pipe is composed of three layers, which are the insulation layer, the protective layer and the pipe body. The insulation layer is made of polyurethane foam, which has good thermal insulation performance and compressive performance; The protective layer is made of polyethylene plastic, which can effectively protect the insulation layer from the external environment; The pipe body is made of high-quality steel pipe, which has high strength and corrosion resistance.
2. Thermal insulation performance.
The insulation performance of polyethylene sheathed polyurethane insulation steel pipe is very good, and its thermal conductivity is low, which can effectively prevent the transfer of heat. At the same time, the closed cell rate of the material is as high as more than 92%, which can effectively prevent the penetration of water vapor, so as to ensure the long-lasting insulation effect of the pipeline.
3. Durability.
The durability of polyethylene sheathed polyurethane insulation steel pipes is very good, and its service life can be as long as more than 50 years. This is mainly due to the protective effect of its protective layer, which can effectively resist the influence of external factors such as ultraviolet rays, oxidation, and chemical corrosion, and ensure the service life of the pipeline.
Fourth, environmental performance.
The environmental performance of polyethylene sheathed polyurethane insulation steel pipe is also very outstanding. It does not use any harmful substances in its production process and is harmless to the environment. At the same time, the material will not produce any harmful substances during use, which is environmentally friendly.
Fifth, easy to install.
The installation of polyurethane insulated steel pipes with polyethylene sheath is very simple and does not require special tools and skills. The connection method can be welding, flange connection, etc., which is convenient and fast. At the same time, the material has a small bending radius and can adapt to a variety of complex pipe layouts.
Sixth, easy maintenance.
The maintenance of polyethylene sheathed polyurethane insulation steel pipe is very convenient. Its smooth surface is not prone to fouling, which can reduce the amount of cleaning and maintenance work. At the same time, the material has good anti-aging properties and can maintain its performance and service life for a long time.
To sum up, polyethylene sheathed polyurethane insulation steel pipe has the advantages of excellent thermal insulation performance and durability, environmental performance, easy installation and convenient maintenance, and is widely used in construction, chemical industry, petroleum and other fields. In the future, with the increasing attention to environmental protection and energy saving, the application prospect of this material will be broader.
