In a fire tube boiler, what is a potential consequence of improperly rolled tubes?

In a fire tube boiler, improperly rolled tubes can lead to severe pressure loss within the system. This occurs because the tubes play a crucial role in maintaining the structural integrity of the boiler and ensuring a tight seal for steam and hot gases. If the tube connections are not rolled properly, it may create gaps or weak points, allowing steam or water to escape. This loss of pressure can disrupt the entire heating process, leading to inefficient operation and potentially causing further damage to the boiler system. The consequences of improper tube rolling can escalate, risking significant operational failures and safety hazards. Thus, understanding the importance of correct tube rolling is essential for maintaining optimal performance and safety in a fire tube boiler.
