How is a gusset stay attached to a boiler?

A gusset stay is a structural component used in a boiler to provide additional support and maintain stability. It is typically attached to the boiler's shell by riveting it with angle iron. This method creates a strong, resilient connection that allows for the transfer of stresses throughout the boiler structure, ensuring that it can withstand operational pressures and thermal expansions.

Riveting with angle iron is effective because it provides a permanent connection that can accommodate some movement without sacrificing integrity. The use of angle iron enhances the structural strength by providing a greater surface area for the connection, leading to improved load distribution.

Other methods, such as welding, bolting, or cementing, are not commonly used for gusset stays. Welding may create a rigid joint but lacks the flexibility needed for certain applications in boiler construction. Bolting typically applies to components requiring regular maintenance or adjustments, while cementing is not suitable for structural supports due to its lack of tensile strength and ability to withstand heat and pressure. Thus, riveting with angle iron is the preferred method for attaching gusset stays in boiler assembly.
