  The causes of boiler tube rupture

  Boiler tubes are critical components in boiler systems, tasked with carrying high-temperature and high-pressure steam or water. They are typically made from seamless pipes, valued for their strength and uniformity, or ERW pipes, preferred for cost-effectiveness and precision. A tube failure—whether seamless or ERW—can seriously compromise boiler safety and may even result in severe accidents. The reasons behind boiler tube failures are complex and multifactorial, involving material selection, design, manufacturing, operation, and maintenance. Below is a systematic analysis.
