Why Reformer Tube Shutdown Inspections Are Crucial for Plant Safety and Performance
Reformer tubes are the unsung heroes in high-temperature processes like Steam Methane Reforming (SMR), ethylene cracking, and DRI production. But without proper inspection during shutdowns, even the most robust tubes can become liabilities.
Shutdown season is more than just downtime—it's your opportunity to assess, analyze, and act.
So what should you look for during inspection?
✅ Visual Inspection: Start with the basics. Surface cracks, bulging, and discoloration often indicate early signs of creep or carburization.
✅ Dimensional Checks: Loss of circularity? That could be internal pressure damage. Track changes using precision tools and compare them with past shutdown records.
✅ Hardness Testing: Changes in surface or through-wall hardness may signal metallurgical issues like carbon migration or embrittlement—especially in flame-exposed zones.
✅ Infrared Thermography: Even post-shutdown, residual heat patterns can reveal thermal anomalies. IR scans help pinpoint problematic burner zones.
✅ Ultrasonic Thickness Gauging (UTG): This test reveals wall thinning due to oxidation—especially critical near weld seams or burner rows.
✅ Weld Zone Checks: Welds are stress-prone. Conduct DPT and UT tests to catch microcracks before they grow into failures.
✅ Internal Scaling & Spalling: Internal oxide layers and flaking can compromise structural integrity and contaminate the downstream process.
Pro tip: Maintain a log for each tube—compare readings over cycles to detect dangerous trends early.
