In modern industry and infrastructure construction, pipeline systems play an important role in transporting various media. Among them, galvanised iron prefabricated overhead insulated pipelines, with their unique performance and significant advantages, have been widely used in many fields, becoming one of the key facilities to ensure the normal operation of production and life.
Urban central heating is an important application scenario for galvanised iron prefabricated overhead insulated pipelines. In winter, to provide a warm and comfortable indoor environment for thousands of households, it is necessary to efficiently transport the hot water or steam generated by power plants to each user terminal. Thanks to its excellent insulation performance, the galvanised iron prefabricated overhead insulated pipeline can effectively reduce heat loss of hot water or steam during transportation. The internal polyurethane rigid foam insulation layer acts like a thick “quilt”, tightly wrapping the steel pipes that transport the medium, greatly reducing heat loss and ensuring that the hot water or steam can maintain a high temperature during long-distance transportation, meeting the heating needs of users. At the same time, the outer protective pipe of the pipeline is made of galvanised iron material, which has good corrosion resistance, can be used outdoors for a long time, and resists the erosion of rain, snow, and corrosive substances in the air, ensuring the long-term stable operation of the heating pipeline system, reducing maintenance and replacement costs due to pipeline damage, and providing a solid guarantee for the reliability of urban central heating.
The construction and operation of cold storage also benefit from galvanised iron prefabricated overhead insulated pipelines. In cold storage, a low-temperature environment is required to store various goods such as food and medicine. Galvanised iron prefabricated overhead insulated pipelines can be used to transport low-temperature media, such as chilled brine, to maintain the low-temperature state within the cold storage. Its excellent insulation performance can reduce the heat absorption of low-temperature media during transportation, preventing temperature fluctuations in the cold storage due to heat intrusion, ensuring the storage quality of goods within the cold storage. In addition, the sturdiness and durability of the galvanised iron outer protective pipe allow the pipeline to adapt to the low-temperature, humid, and potentially collision-prone environment within the cold storage, making it less prone to damage and providing a reliable pipeline transportation system for the long-term stable operation of the cold storage.
The chemical industry is a field with diverse and extremely stringent requirements for pipeline performance. In the chemical production process, it is necessary to transport various media with different properties, as well as high-temperature and high-pressure process fluids. Galvanised iron prefabricated overhead insulated pipelines have shown strong adaptability in the chemical industry. The corrosion resistance of its galvanised iron outer protective pipe allows it to operate stably in corrosive environments such as acid and alkali fumes, protecting the internal working steel pipe and insulation layer from corrosion damage. At the same time, the high strength and good sealing performance of the pipeline can withstand the high-pressure environment in the chemical production process, ensuring the safe and reliable transportation of media. In addition, according to the special needs of chemical production, this pipeline can also be specially designed and customised to various specifications according to customer requirements, meeting the specific requirements of different chemical processes, and providing strong support for the safe production and efficient operation of the chemical industry.
