Insulated joints are manufactured using insulating materials, offering strong insulation properties, hence the name. Their primary function is insulation, with a resistance of 10MΩ, significantly extending the operational lifespan of pipelines. The lifespan is exceptionally long, matching that of the pipeline itself. Moreover, through advanced technology and processes, these insulated joints provide high strength and offer various connection options for users, including flanges, welding, and threaded connections. Insulated joints are a general term for pipeline connectors that meet the requirements of sealing, strength, and electrical corrosion prevention for buried steel pipelines. They include components such as assembly parts, insulating plates, fillers, sealing rings, and short pipes.
