Foaming tube for glass production

The utility model provides a foaming pipe for glass production. The foaming pipe comprises an upper transverse pipe, a lower transverse pipe and a longitudinal pipe for connecting the upper transverse pipe and the lower transverse pipe, a feeding pipe is arranged on the upper transverse pipe, a discharging pipe is arranged on the lower transverse pipe, and the longitudinal pipes are arranged in the length direction of the upper transverse pipe at intervals. The upper transverse pipe and the lower transverse pipe are arranged in parallel, one end of each longitudinal pipe is communicated with the upper transverse pipe, and the other end of each longitudinal pipe is communicated with the lower transverse pipe; a plurality of foaming holes are formed in the longitudinal pipe at intervals, and foaming assemblies are arranged at the positions, corresponding to the foaming holes, of the longitudinal pipe. The foaming pipe is simple in structure, stable and reliable, the foaming assembly is arranged at the position
