  • Lesson 4 • Defining Inspection Scope and Methods

    Guides selection of inspection techniques matched to identified damage mechanisms and equipment geometry. Ensures complete coverage without redundant effort.

  • Lesson 5 • Acceptance Criteria and Fitness for Service

    Establishes minimum thickness, flaw size, and surface condition limits derived from applicable standards. Connects pre-inspection planning to pass/fail decision-making in the field.

Chapter 4See details

Visual Inspection Techniques

  • Lesson 1 • Documenting and Reporting Visual Findings

    Teaches standardised sketching, photography, and written description of visual anomalies. Produces defensible inspection records that support engineering evaluation.

  • Lesson 2 • Principles of Visual Examination

    Establishes lighting requirements, viewing angles, distance limits, and eye qualification standards for visual inspection. Provides the scientific basis for reliable visual detection.

  • Lesson 3 • Weld and Joint Visual Examination

    Applies weld visual acceptance criteria to identify surface-breaking cracks, undercut, porosity, and misalignment. Connects visual findings to decisions about further NDE.

  • Lesson 4 • External Surface and Insulation Inspection

    Covers external corrosion under insulation, coating condition, and support contact areas. Identifies external degradation that is often overlooked during internal-focused inspections.

  • Lesson 5 • Internal Surface Examination

    Guides systematic examination of shell interiors, tube sheets, heads, and nozzle bores for corrosion, cracking, and deposits. Builds a repeatable internal inspection sequence.
