Typical Application Methods for Near drum inspections

• Continuous Revolution Scanning: Enables uninterrupted, 360-degree inspection of the drum surface to capture comprehensive data in a single rotation, reducing inspection time and increasing accuracy.

• High-Resolution Imaging: Uses advanced imaging technology to capture detailed visual data, allowing for precise detection of small cracks, pitting, and surface corrosion.

• Ultrasonic Testing (UT): Employs ultrasonic waves to measure wall thickness and detect internal flaws, commonly used to identify corrosion or erosion in steam drums.

• Magnetic Particle Inspection (MPI): Detects surface and slightly subsurface discontinuities using magnetic fields, ideal for identifying cracks in ferromagnetic materials.

• Radiographic Testing (RT): Uses X-rays or gamma rays to inspect the internal structure of the drum, helping detect subsurface defects such as voids and inclusions.

• Thermographic Inspection: Applies infrared thermography to detect temperature variations, which can indicate areas of wear, corrosion, or structural weaknesses.

• Eddy Current Testing (ECT): Utilizes electromagnetic induction to detect surface and near-surface flaws in conductive materials, often used in non-destructive testing of steam drums.

• Visual Inspection (VI): Involves close-up visual examination, often enhanced with borescopes or robotic cameras for inspecting hard-to-reach areas inside the drum.
