API SIRE is very similar to API SIFE for Fixed Equipment except that it focuses on rotating machinery (pumps, compressors, turbines). It is about how an inspector verifies quality during manufacturing and testing. Success comes from combining mechanical knowledge + inspection stages + documentation control.
What the SIRE Exam Really Tests
Rotating Equipment Basics
- Pumps (centrifugal, positive displacement)
- Compressors (reciprocating, centrifugal)
- Turbines (basic understanding)
Inspection Role
- Vendor surveillance
- Inspection points (hold/witness/review)
- QA/QC documentation
Testing & Standards
- Performance testing
- Mechanical run tests
- Vibration, alignment, tolerances
📅 5-Week Study Plan (Efficient & Practical)
Week 1: Fundamentals of Rotating Equipment
Focus on how machines work
Topics:
- Centrifugal pumps (most important)
- Basic compressor types
- Key components:
- Shaft
- Bearings
- Seals
- Impellers
👉 Goal: Understand function + failure points
Week 2: Components & Failure Modes
Study:
- Bearings (rolling & sleeve)
- Mechanical seals
- Couplings

Common failures:
- Cavitation
- Misalignment
- Bearing failure
- Seal leakage
👉 Goal: Link component → failure → cause
Week 3: Inspection & Testing
Key areas:
- Mechanical Run Test (MRT)
- Hydrostatic testing
- Performance testing
- Vibration measurement
- Alignment checks
👉 Goal: Know what inspectors verify and when

Week 4: Codes, Standards & Documentation
Important standards:
- Guide for Source Inspection and Quality Surveillance of Rotating Equipment
- API Standard 610 (VERY IMPORTANT)
- API Standard 617
- API Standard 677
Learn:
- Acceptance criteria basics
- Inspection Test Plans (ITP)
- Material certificates (MTRs)
- Data books
👉 Goal: Be able to verify compliance on paper
Week 5: Practice + Weak Areas
- Solve mock questions
- Review weak topics
- Focus on scenarios
🔧 Key Topics You MUST Master
- Centrifugal Pumps (High Priority)
- How flow is generated
- Head vs flow concept
- Cavitation (very important)
👉 Expect many questions here
- Bearings & Seals
- Rolling vs sleeve bearings
- Lubrication importance
- Mechanical seal operation
- Alignment & Vibration
- Misalignment effects:
- Vibration
- Bearing damage
- Basic vibration concepts:
- High vibration = problem indicator
Inspection Points (Exam Favorite)
Know clearly:
- Hold Point (H) → must stop
- Witness Point (W) → optional observation
- Review Point (R) → document check
Documentation Flow (Critical)
You should understand:
- ITP (Inspection Test Plan)
- Test reports
- Inspection release notes
👉 Think: Can I approve this equipment before shipment?
⚠️ Common Mistakes (and Fixes)
❌ Ignoring rotating equipment basics
✔️ You must understand how machines work, not just inspection
❌ Memorizing without visualization
✔️ Use diagrams (impellers, seals, bearings)
❌ Weak understanding of testing
✔️ Focus on:
- Mechanical run test
- Performance test
- Acceptance criteria
❌ Skipping API 610
✔️ This is the core standard—don’t ignore it
🧠 Smart Study Strategy
Use This Thinking Model:
Component → Function → Failure → Detection → Inspection
Example:
- Bearing → supports shaft
- Failure → overheating
- Detection → vibration/temp
- Inspection → Mechanical Run Test (MRT)
⏱️ Daily Study Routine (Example)
- 1–1.5 hr core topic
- 30 min revision
- 20–30 practice questions
🎯 Exam Strategy
- Start with easy questions
- Use elimination
- Don’t overthink technical questions
- Focus on inspector’s role
