The insulation of ptfe lined pipe first provides a reliable safety barrier for the overall transportation system when transporting conductive media. Conductive media may generate static electricity due to friction and collision during the flow process. If the pipe itself is conductive, static electricity may be transmitted to equipment or human body through the pipe, causing safety hazards. However, polytetrafluoroethylene is non-conductive and can block the conduction path of static electricity, allowing static electricity to dissipate locally inside the medium or the inner wall of the pipe, avoiding the accumulation of static electricity to form high voltage, reducing the risk of fire and explosion caused by static sparks, and building a solid safety line for the transportation of conductive media.
Its insulation ensures that the transportation process of conductive media is not interfered by external electric fields. In some industrial environments, there may be equipment such as motors and transformers that generate electromagnetic fields around. If the pipe is conductive, the electromagnetic field may affect the conductive medium inside the pipe through the pipe, causing the electrical properties of the medium to change. The insulation characteristics of ptfe lined pipe can isolate the external electromagnetic field like a barrier, allowing the conductive medium to maintain a stable electrical state during the transportation process, and will not change its inherent conductive properties due to external interference, ensuring that the medium can still meet the use requirements when it reaches the destination.
For conductive media that need to accurately control flow or pressure during transportation, insulation avoids interference from stray currents. When the pipeline is conductive, the current generated by the flow of the medium may form a loop with the pipeline, interfering with the normal operation of equipment such as flow meters and pressure sensors, resulting in inaccurate measurement data. However, ptfe lined pipe is non-conductive and will not form a current loop, ensuring that the measuring equipment can accurately capture the flow state of the medium, providing a reliable data basis for the control system, making the regulation of the transportation process more accurate, and avoiding deviations in the amount of transportation caused by data errors.
When transporting corrosive conductive media, the combination of insulation and corrosion resistance shows unique advantages. Some conductive media are also corrosive. If metal pipes are used, not only will the pipeline be damaged due to corrosion, but metal ions generated by corrosion may also enter the medium, affecting its conductivity. ptfe lined pipe is not corroded and can maintain insulation, which not only avoids the pipeline from being eroded by the medium, but also prevents metal ions from contaminating the medium, making the conductive medium safe and pure during transportation, extending the service life of the pipeline while ensuring the quality of the medium.
Its insulation reduces the electrochemical corrosion between the conductive medium and the pipeline. When the conductive medium comes into contact with the metal pipe, a galvanic cell may be formed, causing electrochemical corrosion and accelerating the aging of the pipe. As an insulating layer, the ptfe lined pipe isolates the conductive medium from the outer layer of the metal pipe, preventing the formation of the galvanic cell and fundamentally avoiding the occurrence of electrochemical corrosion. This allows the metal material on the outer layer of the pipe to focus on providing structural support without worrying about being corroded by the conductive medium, which indirectly extends the service life of the entire pipeline system.
For conductive media that need to be transported over long distances, insulation ensures the stability of the transportation process. During long-distance transportation, the pipeline may pass through different environments. If the pipeline is conductive, the difference in environmental potential in different areas may cause current to flow in the pipeline, affecting the stable transportation of the medium. The insulation of the ptfe lined pipe blocks this potential conduction, allowing the conductive medium to be unaffected by the environmental potential along the way during long-distance flow, maintaining a uniform flow rate and a stable state, and will not cause the medium to be unevenly distributed in the pipeline or flow obstructed due to the potential difference.
In addition, insulation provides flexible adaptation for the diverse transportation scenarios of conductive media. Whether it is conveying conductive liquids in chemical production or conveying conductive slurries in the electronics industry, PTFE lined pipe can adapt to the needs of different scenarios with its insulation properties. It does not require additional insulation devices for the characteristics of different conductive media, and can meet the insulation requirements by itself, simplifying the structure of the conveying system, reducing the complexity of system construction, and allowing the conveying of conductive media to be carried out efficiently and safely in various scenarios.
