HRSG

Quality inspection of an HRSG is essential to ensure reliable operation, safety, and compliance with project requirements. The inspection covers major components such as the duct casing, drums, fin tubes, headers, and structural steel. Key activities include checking material identification, dimensions, welding quality, tube alignment, surface condition, and coating. NDT methods such as UT, MT, PT, and RT may be applied to verify weld integrity where required. All inspection results should be properly documented, and any nonconformities must be corrected before final acceptance and delivery.
