Visual Inspection and Acceptance of Pipeline Welds

Detailed Visual Inspection of Pipeline Welds

     On-site workers climb to high positions to conduct visual inspection on thermal pipeline welds. Every butt weld joint is examined thoroughly to detect surface defects including porosity, cracks and incomplete penetration.

      High-temperature and high-pressure pipelines serve as core pressure-bearing components of power plants, and weld quality is directly tied to unit operational safety. The project team takes visual acceptance as a critical pre-procedure for non-destructive testing and implements full-process quality patrol inspection. Potential pipeline leakage risks are eliminated from the source. The whole pipeline installation process is controlled in a standardized manner to ensure the orderly construction of the plant piping system.
