Integrated steel plants are huge industrial mammoths that process millions of tonnes of minerals, water and air to convert them to millions of tonnes of finished products. In that process, these plants generate job opportunities to thousands of people directly and indirectly. They are the economic prime mover engines that keep working non stop to fill the coffers of the national exchequer even while their own balance sheets are not so comfortable!
All metallic structures are subject to failure after some time due to various mechanisms such as creep, corrosion, inter-crystalline changes, etc. Metal pipes and vessels may look outwardly and physically in reasonably good shape even after years of service. However, their inherent strength to withstand load and pressure might have changed much over time. Thus a new pipe and an old serviced pipe having the same physical features may not give the same performance; the latter might fail unexpectedly. However, such failures happen only once in a blue moon!
But all accidents cause due to cumulative errors and omissions of many individuals over a period of time. It is the short term and long term actions, attitudes and reactions of the people at all levels that are more important and responsible to effect well thought actions that keep the complex equipment and machinery work safely.
