(PDF) Creep Failure of Reformer Tubes in a Petrochemical Plant - …

It is estimated that 10% of all power-plant breakdowns are caused by creep fractures of boiler tubes. In general, 30% of all tube failures in boilers and reformers are caused by creep. This paper gives details of four case studies in which internally pressurised tubes failed by creep bulging and rupture (two boilers, one superheater and one reformer).

Critical Failure Analysis of Superheater Tubes of Coal-Based Boiler

2004/12/1 · Creep is the root cause of 30% of all tube failures in boilers and reformers by itself [10]. Overheating is another main reason for premature rupture of reheater and superheater tubes.

Finding the Root Cause of Boiler Tube Failures

Causes: Short-term overheat failures are most common during boiler start-up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow.

Fatigue Damage of Waterwall Tubes in a 1000 MW USC Boiler

2018/7/15 · In this article, the failure of waterwall tubes in a supercritical boiler was analyzed, a full investigation into the failure cause was carried out involving in visual examination, optical microscope, mechanical test and phase analysis. The results show that the failure occurred due to thermal fatigue caused by temperature change.
