PE and steel skeleton composite pipe and pipe connecting structure

Abstract

The invention relates to the field of pipes, in particular to a PE and steel skeleton composite pipe and a pipe connecting structure. Comprising a pipe body, a bellmouth end and a spigot end are fixedly arranged at the two ends of the pipe body respectively, and the bellmouth end is used for bearing the spigot end of another pipe; at least one telescopic wave is arranged in the socket end, an inner groove of the telescopic wave is used for installing a sealing ring, the outer wall of the spigot section can be matched with an inner ring of the sealing ring, a first pair of locking pieces is fixedly arranged on the socket end, and a second pair of locking pieces which can be fixedly locked with the first pair of locking pieces of another pipe are fixedly arranged on the pipe body; the spigot end can axially abut against the socket end or the pipe body of another pipe, the axial positions of the first pair of locking pieces relative to the second pair of locking pieces of the other pipe are arranged in a relatively adjustable mode, and therefore the stretching degree of the telescopic waves can be adjusted, and the tightness degree of the sealing ring can be adjusted. According to the PE and steel framework composite pipe and pipe connecting structure, the pipe and the connecting structure are convenient to install and good in sealing performance, and the tightness of the sealing rings can be adjusted.
