What tool is primarily used to ensure proper alignment of boiler components during assembly?

The use of alignment tools and fixtures is essential during the assembly of boiler components to ensure precision and proper alignment. These tools are designed specifically for aligning components accurately, which is critical for the integrity and safety of the boiler system. Proper alignment helps prevent issues such as stress on piping or structural components, enhancing the overall performance and longevity of the boiler.

Alignment tools often include devices like laser levels, alignment rods, and other specialized fixtures that can measure and adjust the position of parts accurately. The precision offered by these tools is critical in a field where even small misalignments can lead to significant operational issues.

While calipers, wrenches, and measuring tape have their importance in general assembly and measurements, they do not specifically address the unique requirements for aligning boiler components like dedicated alignment tools do. Calipers are primarily used for precise measurements of thickness and diameter, wrenches are used for fastening bolts and nuts, and measuring tape is useful for general distance measuring. However, they lack the specialization required to ensure that the components are aligned correctly during assembly, which is the primary reason why alignment tools are the best choice for this task.
