Problems solved by technology

In the actual industrial production process, there is a lack of scientific experimental test systems and test methods to quantitatively describe the impact of multiphase flow with different medium concentrations, different temperatures, and different flow rates on the erosion and corrosion characteristics of pipes
[0003] The previous research results show that the traditional erosion corrosion test system is mostly rotary, which cannot accurately simulate the erosion corrosion process of the actual industrial pipeline system, and the concentration, flow rate and temperature of the corrosive medium during the experiment cannot be accurately controlled, resulting in the erosion corrosion test. The test results cannot truly reflect the actual industrial conditions

Abstract

The invention discloses an intelligent cyclic flowing type erosion corrosion testing system and testing method. The system comprises a temperature control system, a test piece erosion corrosion system, a test solution circulating system and a test solution stirring system. The test piece erosion corrosion system comprises a rubber plug, a tower connector, a connecting shaft rod, a test piece platform and a test piece and is mounted between the top and the bottom of a cylindrical test piece tank. One end of a pipeline is connected with the rubber plug while the other end is connected with one end of an upper corrugated pipe, the other end of the upper corrugated pipe is connected with a water pump, and one end of a lower corrugated pipe is connected with the rubber plug while the other endextends into a stirring tank to form the test solution circulating system. A third guide rail is connected with a motor angle part which is connected with a motor, and one end of an extension shaft isconnected with one end of the motor through a coupler while the other end extends into a test solution tank to form the test solution stirring system. The temperature control system comprises three groups of thermocouples, a control circuit and wires. Test piece flushing under different operating conditions is realized, and testing precision is improved.

Description

technical field [0001] The invention belongs to an erosion corrosion test system in the field of flow corrosion protection, and in particular relates to an intelligent circulation flow type erosion corrosion test system and a test method. Background technique [0002] Under the trend of internationalization and globalization of production, safety issues in the continuous industrial production process have increasingly become the focus of all walks of life. In petrochemical, coal chemical, nuclear power industry, ocean engineering and other process industries, multiphase fluids containing corrosive media are highly corrosive to pressure pipes, especially when they contain both corrosive media and solid particles Under the working conditions, it is very easy to cause flow corrosion failure of the pressure pipe and valve system. In the actual industrial production process, there is a lack of scientific experimental testing systems and testing methods to quantitatively describe...
