The utility model provides a compact tee bend flanged pipeline with bolt avoiding structure, which comprises a tee bend pipeline and three flanges arranged on the tee bend pipeline. The tee bend pipeline comprises a main pipeline, a branch pipeline connected perpendicularly to the main pipeline at the middle of the main pipeline, and two avoiding parts arranged oppositely on the branch pipeline. The flange is used for connecting and fixing the tee bend pipeline to an external pipeline and comprises a body and a plurality of bolt mounting holes formed in the body. The bolt mounting holes are used for mounting bolts to bolt the external pipeline to the tee bend pipeline. The avoiding part is in the shape of a tapered surface in the cross section perpendicular to the opening direction of the bolt mounting hole, and the cross section of the tapered surface close to the main pipeline is small. The avoiding part is arranged at the connection between the main pipeline and the branch pipeline and is used for avoiding the bolts, so that the bolts can be installed more conveniently and quickly, thereby improving the assembly efficiency.
