Erosion resistance testing system and method for anti-corrosion pipeline

The invention provides an erosion resistance testing system for an anti-corrosion pipeline. The system comprises a test working platform, a liquid storage tank (12), a simulation loop pipeline, a sample clamping system and a test jet nozzle (7), a test fluid composed of a test solution and a certain mass fraction of sand is contained in the liquid storage tank, and the simulation loop pipeline isused for allowing the test fluid to flow and comprises: a main body supporting pipeline subsystem composed of a stainless steel pipe, a valve and a flange; a mortar subsystem, which comprises a mortarpump (4), a mortar pump cooling water pump (9) and a variable frequency controller (10); a water replenishing subsystem, which comprises a water replenishing port (5); and a cooling water subsystem,which comprises a cooling water inlet (1), a cooling water outlet (2) and a cooling water pipe (3); the sample clamping system comprises a sample clamp (14) and a sample seat (15), a sample (13) is clamped on the sample clamp w
