A case history is presented relating to corrosion of boiler plant which provides clear examples of the problems that can arise with inadequate attention to water treatment. Failures were observed in various components of the steam circuit of a urea p
Case history: Stress corrosion cracking of reactor riser by polythionic acid in a petroleum refinery

British Corrosion Journal. 27:315-316
This paper describes a microstructural investigation to determine the cause of the failure of a reactor riser in a petroleum refinery. The investigation revealed that failure had occurred as a result of stress corrosion cracking caused by polythionic

The behaviour of different materials of construction during the cracking of ammonia at 600°c, and at an operating pressure of 100 mm of water (∼100 Nm−2 above atmos. pressure) was studiedfor periods up to 1500 h. Carbon steel suffered decarburis
