The invention discloses a multiphase
erosion corrosion coupling damaged pipeline
simulation experiment test
system and method. Comprising a
screw pump, a
pressure measurement module, a high-pressure rubber
expansion joint, a
gas release module, a
check valve, a special feeding module, a
temperature control measurement module, a
wall shear force measurement bin, a fluid acceleration module, a
buffer tank, a pipeline pressurization module, a temperature sensor, an
electric control cabinet and a
copper pipe coil cooler which are arranged on a circulating pipeline. The problem that the gas-liquid / gas-liquid-
solid multi-phase
erosion and
corrosion coupling damage rule and the predicted damage rate are difficult to test in a high-
sulfur, high-
chlorine and high-acid severe environment in a
petrochemical chemical production device is solved, and the damage rate of the
petrochemical chemical production device is predicted by designing a special feeding structure, a pressurizing structure, an accelerating structure, a constant temperature structure, an anti-
corrosion structure, an anti-abrasion structure, an anti-vibration structure and other structures and a temperature, flow, concentration and pressure precise regulation and
control system. Long-time stable operation and accurate measurement of multi-phase scouring and corrosion
coupling damage are realized, and safety evaluation and
risk prevention and control of complex flow-induced damage of a
petrochemical chemical production device are effectively supported.
