Manufacturer of overhead polyurethane iron sheet insulation pipe

Yuehua​Manufacturer of overhead polyurethane iron sheet insulation pipe，Various internal medium pipe materials can be selected according to different requirements of users. The insulation layer material is polyurethane foam plastic or composite insulation material. [The thickness of the insulation layer is 30-150mm] When the temperature of the transmission medium is -50 ℃ -120 ℃, rigid polyurethane foam plastic is selected as the insulation layer. The third layer is the outer protective layer consisting of galvanized white iron spiral ducts, fiberglass wrapped pipes, and anti-corrosion steel pipes. Its functions are twofold: firstly, to protect the polyurethane insulation layer from mechanical damage caused by hard objects; secondly, to prevent corrosion and waterproofing. Fiberglass wrapped pipes and anti-corrosion steel pipes. As an integrated material for building insulation and waterproofing, prefabricated buried insulation pipes are made of polyurethane rigid foam, which breaks the shortcomings of traditional pipeline insulation building materials and achieves both insulation and waterproofing.

1. Polyurethane rigid foam has multiple functions as a single material, as well as insulation, waterproofing, sound insulation, vibration absorption and many other functions. Yuehua polyurethane galvanized iron sheet insulation pipe enterprise steel plate should have uniform deformation, low residual stress, and no scratches on the surface. Therefore, the selection of steel plate for making spiral steel pipe should be careful, and the surface should be uniform without scratches. The processed spiral steel pipes have greater flexibility in the size specifications of diameter and wall thickness, especially in the production of high-grade thick walled pipes, especially small and medium-sized thick walled pipes. They have the advantages of other processes and can meet more requirements of users in terms of spiral steel pipe specifications. The diameter and size specification range of spiral steel pipes should be flexibly controlled, and their good advantages should be utilized to meet the broad needs of more users, so that spiral steel pipes can be popularized and promoted. Steel pipelines are generally processed and produced using Q235 carbon steel as raw material. Due to its high mechanical strength, it can withstand large internal and external pressures and can be made into water pipelines with a diameter exceeding 800mm. It is currently one of the commonly used large-diameter buried pipelines in China. Use steel pipelines in the soft soil foundation of the middle and lower reaches of the Yangtze River. Large diameter insulated steel pipe is an upgraded cost-effective product of traditional steel plastic pipe and galvanized pipe. It has comprehensive characteristics, including high strength, high elongation, good low-temperature brittleness, and small expansion coefficient of steel pipes, as well as advantages such as corrosion resistance, wear resistance, and low fluid resistance of plastic pipes. It belongs to a new type of green large-diameter pipe for water supply and drainage, anti-corrosion, and is increasingly widely used in various industries in China. Anti corrosion and insulation steel pipes refer to insulation and anti-corrosion measures that ensure the temperature inside and on the surface of the working steel pipe in different working environments, in order to slow down or prevent corrosion and deterioration under the chemical and electrochemical effects of external media or metabolic activities of microorganisms.

Manufacturer of overhead polyurethane iron sheet insulation pipeThe primary issue with insulated steel pipes for heating is the reliability of tight waterproofing. In addition, they must have good mechanical strength. Due to their high strength, steel sleeves are connected by welding, and their waterproof sealing performance is highly reliable. In addition, their high temperature resistance is unmatched by other external protective pipes. Prefabricated polyurethane insulation pipes are coated with a second degree inorganic zinc rich primer (temperature resistance ≥ 400 ℃) anti-corrosion coating. The pipe ends are sealed with polyethylene film or three-layer PE cold wrapping tape to prevent moisture from entering before installation or water from entering during construction. The insulation material is wrapped with multiple layers of staggered seams, effectively reducing heat loss, while controlling the surface measures of the outer jacket to prevent the formation of cold bridges, thus ensuring the temperature control of the anti-corrosion layer of the outer 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.
