Description 
The Liquid Penetrant Examination Procedure defines a clear, structured, and reliable methodology for detecting surface-breaking defects—particularly cracks—on welds and metallic components in Oil & Gas, EPC, and industrial projects. This procedure establishes all mandatory technical and operational requirements to ensure Liquid Penetrant Testing (PT) is performed in full compliance with applicable codes, Client specifications, and project quality requirements. 

Key Benefits 

• Standardized and field-ready PT methodology 
• Ensures reliable detection of surface defects and discontinuities 
• Fully aligned with international codes and Client requirements 
• Reduces inspection variability and non-conformities 
• Ready to use, clear, and easy to implement on site or in workshops
