Daily Care of Electrofusion Fittings: Key Measures to Extend Lifespan and Ensure System Stability

As core connecting components in plastic piping systems, the stable operation of electrofusion fittings directly affects the reliability and safety of the entire pipeline network. Although the electrofusion process provides them with excellent sealing and strength, scientific daily care is still necessary during long-term use to slow down aging, prevent potential problems, and thus extend their service life and reduce maintenance costs.

 

First, visual inspection and environmental monitoring should be emphasized. Regular inspections can promptly detect problems such as cracks, deformation, or abnormal melting marks on the surface of fittings, paying particular attention to components in areas with high temperatures, chemical corrosion, or frequent mechanical impacts. For buried electrofusion fittings, pipeline detection technology can be used to assess changes in the surrounding soil moisture and pH to prevent material performance degradation due to external environmental erosion.

 

Second, maintaining cleanliness and intact protective coatings are fundamental measures. Adhering mud, oil, or corrosive residues will accelerate material aging. Use a neutral detergent to gently wipe the surface, avoiding scratches from hard tools. For fittings exposed to the elements or UV radiation, the integrity of the UV-protective layer should be checked regularly, and professional repair or recoating should be performed as needed to inhibit photo-oxidative degradation. Secondly, pay attention to operating parameters and load conditions. Although electrofusion fittings have strong pressure and temperature resistance, long-term overload operation can easily lead to hidden damage. It is essential to ensure that the pressure and temperature changes of the medium within the pipeline are within the design range, avoiding thermal stress concentration caused by sudden cooling and heating. In cold winter regions, special attention should be paid to antifreeze measures to prevent damage to the joints caused by the freezing and expansion of the medium.

 

Finally, establish standardized maintenance records and periodic plans, archiving inspection results, cleaning records, and replacement information to provide data support for subsequent decision-making. Through systematic maintenance, not only can the durability and safety of electrofusion fittings be improved, but the overall operation and maintenance efficiency of the pipeline network can also be optimized, laying a solid foundation for various fluid transportation projects.
