Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. Symptoms: Intergranular micro-cracking.Loss of ductility or embrittlement of the tube material leading to brittle catastrophic rupture. Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion.
