Lesson 1 • Pipe Support and Hanger Positioning

Verifies support spacing, hanger rod length, and spring hanger cold settings against design data. Ensures structural loads and thermal movement allowances are correctly implemented.

Lesson 2 • As-Built Dimensional Recording

Teaches systematic capture of installed dimensions for as-built documentation and future reference. Produces accurate records that support maintenance, modification, and regulatory audits.

Lesson 3 • Flange Face Alignment and Parallelism

Measures flange face gap, parallelism, and rotational alignment before bolted joint assembly. Prevents joint stress and leakage caused by misaligned mating flanges.

Lesson 4 • Horizontal Alignment Verification

Addresses plumb, offset, and lateral alignment checks for piping runs and equipment connections. Ensures piping routes match design coordinates and avoid interference.

Lesson 1 • Applying Dimensional Tolerances

Explains how to compare measured values against specified tolerances for piping and boiler components. Builds consistent, defensible accept/reject judgment based on documented criteria.

Lesson 2 • Nonconformance Identification

Covers recognition, classification, and immediate control of out-of-tolerance dimensional findings. Ensures nonconforming items are segregated and documented before disposition.

Lesson 3 • Disposition Options and Engineering Review

Presents use-as-is, rework, repair, and reject dispositions and the engineering review process. Connects inspector findings to formal engineering fitness-for-service evaluation.
