Abstract
The invention provides a petroleum pipeline flange connection structure which comprises a connection flange, a connection pipeline, a connection bend, a bolt, a nut, a compensation mat and a connected pipeline. The compensation mat is installed in a groove. The compensation mat is of a circular structure. A center hole is formed in the center of the compensation mat. Positioning grooves are formed in the circumference of the compensation mat. The number of the positioning grooves is the same as that of connection holes in the connection flange. The bolt penetrates through the connection holes in the connection flange and the positioning grooves in sequence to be connected with the nut. The diameter of the positioning grooves is larger than that of the bolt. One end of the connection pipeline is connected with the connection bend. By means of the petroleum pipeline flange connection structure, stress produced by a petroleum pipeline in the connection process can be reduced, free compensation of each pipeline axial line can be achieved on the premise of ensuring tight connection, the pipeline weak portion is prevented from being cracked, and the pipeline leakage phenomenon is avoided.
