The hydraulic system comprises a main pump 4, a pilot pump 6, an auxiliary pump 5, a pilot control valve 7, a two-position four-way reversing valve 8, a main valve 9, a pipe hanger executing mechanism module and a beveling machine executing mechanism module. The beveling machine actuating mechanism module is arranged in the beveling machine 3.

The main valve 9 has four sets of directional oil ports which are respectively a first set of directional oil ports: ports A1 and B1; a second group of directional oil ports: ports A2 and B2; a third group of directional oil ports: ports A3 and B3; a fourth group of directional oil ports: a4 and B4.
