Visual Acceptance of Boiler High-Pressure Pipeline Welds

Visual Acceptance of Boiler High-Pressure Pipeline Welds

     Perform on-site visual inspections on all circumferential welds of boiler high-pressure main pipelines, meticulously checking for surface defects such as undercut, porosity, cracks, and misalignment. Register exclusive serial numbers for all weld joints and retain visual inspection records as pre-inspection evidence prior to pipeline NDT. Eliminate surface welding defects in advance to prevent potential leakage risks during pressure testing and unit operation.
