Description :
Technical guidance for steel sleeve steel steam composite insulated steel pipe. Steel sleeve steel composite insulated steel pipe is a type of underground buried pipeline that can be directly buried without concrete structure. The thermal expansion of the working steel pipe is carried out inside the outer pipe, thereby reducing material costs, shortening construction dates, and ensuring the performance of heating pipelines. It can be widely used in different temperature environments, especially for high-temperature steam pipeline projects. The operating temperature can reach 150 ℃ -450 ℃. Pipeline ports are generally sealed with polyethylene film or three-layer PE cold wrapping tape to prevent moisture or water from entering before installation or during construction. The insulation material is wrapped with multiple layers of staggered seams, effectively reducing heat loss. At the same time, control measures are taken on the surface of the jacket to prevent the formation of cold bridges, thereby controlling the temperature of the anti-corrosion layer of the jacket. Wrapping multiple layers of aluminum foil reflective layer with insulation material effectively reduces heat loss and makes the steam pipeline more economical and reasonable. The drainage system adopts a fully enclosed form. Sex and reliability will have a negative impact on the development of heavy-duty anti-corrosion powder coatings, especially for some key projects that will affect the vital interests and healthy growth of future generations. We must not cause future problems in the use of heavy-duty anti-corrosion epoxy powder coatings due to various interests, otherwise it will cause endless harm
