Visual Acceptance of Boiler High-pressure Pipe Weld Surface

Strictly Guard Welding Quality:  

Launch Special Visual Acceptance for Boiler High-pressure Pipe Welds

     As the core pressure-bearing components of thermal power projects, the high-pressure pipes of boiler heating surfaces directly determine the long-term operational safety of the unit through their welding quality. The project team has comprehensively carried out special visual inspection works for pipeline welds. Construction personnel conducted detailed one-by-one examinations on all circumferential weld joints, focusing on investigating various surface defects such as undercut, porosity, cracks and misalignment, while completing unified numbering and filing for all weld joints.

     As a key pre-process for non-destructive testing, this visual acceptance eliminates surface welding defects in advance and avoids leakage risks during pressure testing and formal operation from the source. The project department strictly implements quality control standards for special equipment and refines full-process inspection specifications. Through refined inspection management, the team firmly safeguards the pressure-bearing safety of high-temperature and high-pressure pipelines, ensuring the steady and orderly progress of boiler body installation works.
