What are the causes of leakage in electric fusion fittings?

Possible reasons for water leakage in electric fusion connections may include:

Quality Issue with Electric Fusion Fittings: The fittings themselves have defects, such as substandard manufacturing processes or poor raw material quality, resulting in unstable connections or inadequate sealing.

2. Welding Parameter Misconfiguration: Incorrect settings of parameters such as current, voltage, and welding time during electrofusion welding may result in incomplete welding and affect the quality of the joint.

Pipe and fitting mismatch: The specifications and models of the pipes and fittings do not match, or they are not compatible products from the same manufacturer, resulting in connection issues.

4. Welding Surface Contamination: Prior to electrofusion, the welding surfaces of the pipes and fittings are contaminated with dust, oil, moisture, and other impurities, which affect the welding quality and sealing properties.

5. Incorrect Installation Procedures: During the installation process, the correct operational procedures were not followed, such as insufficient insertion depth and incorrect angles.

6. Environmental Factors Impact: Extreme temperatures in the construction environment may affect the effectiveness of electric fusion welding and the performance of pipe fittings.

7. Pipeline Damage Due to External Force: After the pipeline installation was completed, it sustained external impacts and compressions, resulting in damage to the electric fusion joints and leakage.

8. Pipe and Fitting Aging: After long-term use, pipes and fittings may experience aging and brittleness, leading to reduced sealing performance at the joint areas and resulting in leaks.
