Reducing the size of a drum line from the connection at the steamer can lead to increased steam pressure in the system. When the diameter of the drum line is smaller, the volume of steam that can pass through is limited, which can cause a buildup of steam pressure upstream of the restriction. This situation can result in excessive pressure that may exceed the design limits of the system, potentially leading to leaks at joints or connections as well as strain on the equipment.

Additionally, this increased pressure is related to how the system is designed for optimal performance. A properly sized line ensures efficient steam flow and minimizes pressure buildup, thus maintaining the integrity and safety of the steamer. Hence, this scenario highlights the importance of maintaining appropriate dimensions in the steam distribution system to prevent operational issues and potential damage.
