The invention discloses an external pressure universal expansion joint. The external pressure universal expansion joint comprises a left connecting pipe and a right connecting pipe, wherein the left connecting pipe is connected with a left outer sleeve, a left corrugated pipe is arranged in the left outer sleeve, and the left outer sleeve and the left corrugated pipe are connected through a left pressure bearing annular plate at one end of the left outer sleeve and the corresponding end of the left corrugated pipe; and the right connecting pipe is connected with a right outer sleeve, a right corrugated pipe is arranged in the right outer sleeve, and the right connecting pipe and the right corrugated pipe are connected through a right pressure bearing annular plate at one end of the right connecting pipe and the corresponding end of the right corrugated pipe. The external pressure universal expansion joint further comprises a middle connecting pipe arranged in the left corrugated pipe and the right corrugated pipe, wherein one end of the middle connecting pipe is connected with the other end of the left corrugated pipe, the other end of the middle connecting pipe is connected with the other end of the right corrugated pipe, a left lining tube is arranged in the left outer sleeve, the free end of the left lining tube is arranged inside the left corrugated pipe, a right lining tube is arranged inside the end, located on the right corrugated pipe, of the middle connecting pipe, and the free end of the right lining tube is arranged in the right connecting pipe. According to the external pressure universal expansion joint, the structure that two groups of external pressure type multi-layer U-shaped corrugated pipes are combined is adopted, the problem of column instability is avoided, and therefore, the external pressure universal expansion joint has the high horizontal compensation capacity under the working conditions of high pressure and high temperature, and can meet the requirement on the compensation capacity of an on-site long-range pipeline.
