This application provides a
pipe connection structure and frame. The
pipe connection structure includes a first
pipe, a second pipe, and a connector. The first pipe defines a first flow path and at least one first mounting hole; the second pipe defines a second flow path and at least one second mounting hole; the connector passes through the first and second mounting holes sequentially, and the connector defines a hollow channel that communicates with the first and second flow paths respectively. By using a connector that passes through the first and second mounting holes sequentially to connect the first and second pipes, thermal stress caused by
thermal expansion and contraction at the weld joint of the first and second pipes can be avoided. This ensures that the connection between the first and second pipes remains structurally stable even under high-temperature operating environments, extending the service life of the pipe connection structure.
