In high-temperature boiler systems, headers serve as vital components for collecting and distributing steam and water, while stub headers act as crucial connecting channels to other boiler elements. These tubular structures are regularly exposed to cyclic thermal loading during cold, warm, and hot startups — making them vulnerable to thermal fatigue over time. To maintain long-term operational saf...
