The invention relates to an X80 steel bent pipe and a process for bending the same, wherein the bent pipe is made of X80 steel. The weight percentage compositions of the steel are: 0.06 to 0.15 percent of C, 0.1 to 0.3 percent of Si, 1.4 to 2.0 percent of Mn, less than or equal to 0.015 percent of P, 0.01 percent of S, 0 to 0.45 percent of Cr, 0 to 0.3 percent of Mo, 0 to 0.3 percent of Cu, 0 to 0.5 percent of Ni, 0.05 to 0.15 percent of Nb, 0 to 0.06 percent of Ti, 0 to 0.06 percent of V, Ceq controlled between 0.36 and 0.44 percent, Pcm controlled between 0.17 and 0.23 percent. The steel controlled rolled steel plate is made into steel pipe and is formed into bent pipe by induction heating bending process. The properties of the bent pipe can completely meet the technical requirement on X80 steel pipes by controlling parameters of heating temperature of the induction heating, bending velocity, cooling velocity, etc. during the bending process, thereby being suitable to be used as bent pipes for oil and gas pipelines.
