Coke Drum Repair Services

Thermal cycling in delayed coking units leads to fatigue cracking in coke drums, especially around shell seam welds and skirt-to-shell joint. Left unaddressed, these cracks compromise structural integrity, causing unplanned shutdowns and costly downtime.

At IGS, we deliver engineered coke drum repair solutions – including ID weld overlay, crack repairs, and structural reinforcement – designed to extend drum life and enable efficient refinery turnarounds.

Why Do Coke Drums Crack?

Every thermal cycle imposes stress reversals that weaken the drum shell, welds, and skirt joints. Over time, this leads to:

  • Shell and seam cracking

  • Bulging and deformation

  • Skirt weld failures

  • Unscheduled shutdowns
