Standard industrial practice for cleaning steam circuits is the use of a low-pressure continuous steam blow, where a steam flow is controlled at conditions defined to create pipe wall forces above what is expected under normal operation. The steam control is commonly accomplished with the use of an orifice plate or a ‘sacrificial’ valve. During the 2017 commissioning of an ethylene production facility in Freeport, Texas a steam line failed and split open while performing a low-pressure continuous steam blow. This paper discusses the details of the failed steam blow, the cause of failure (line irregularities, acoustic induced vibration), and the leverageable corrections made to effectively and safely re-establish and complete the steam blow.
