What is the main function of flaring in boiler tube assembly?

The primary function of flaring in boiler tube assembly is to secure tubes to the tube sheet. This process involves expanding the end of the tube slightly so that it creates a tight, secure fit within the tube sheet, thus preventing leakage of fluids between the tube and the sheet. This secure connection is essential for maintaining operational efficiency and safety within the boiler system, as it ensures that heat transfer occurs effectively while simultaneously minimizing the risk of tube failure or detachment during operation.

Flaring contributes not only to the mechanical stability of the assembly but also impacts the overall integrity of the boiler. A well-secured tube assembly helps the boiler maintain its designed pressure and temperature conditions, which are critical for optimal performance.
