High-temp high-pressure condensation water corrosion simulated experiment device

Abstract

This invention discloses a high temperature high pressure condensed water corrosion analog calculator, including: High temperature high pressure still, control box, condenser, high-pressure bottle and magnetic force drive: The magnetic force drive and the high-pressured still top head through the bolt fastening, the high-pressure bottle but actually trachea and between the high-pressured still air feeder buckles the connection with the spiral, between the condenser and the cooling water outlet pipe the weld joint, the cooling water outlet pipe passed through the high-pressured still top head, is tight with the high-pressured still top head on cap nut the outlet pipe and the high-pressured still top head, the outlet pipe and between the high-pressured still top head carries on the seal through the seal packing collar. In the high temperature high pressure still, rotation axis upside has while has the heat conduction the aqueous medium seal vessel, has the static installment in the seal water vessel interior which cooling uses. The advantages is simulating pipeline crown corrosion situation.

Description

technical field [0001] The invention belongs to the technical field of simulation experiment devices, and in particular provides a high temperature and high pressure condensed water corrosion simulation experiment device. It is suitable for the simulation experiment of the corrosion of the top of the pipeline caused by the condensation of water vapor at the top of the pipeline in the high temperature and high pressure multiphase medium flowing in the horizontal pipeline. The simulation experiment of steam corrosion at the top of pipelines carrying high temperature and high pressure multiphase fluids can be used to evaluate the corrosion inhibition efficiency of gas-phase corrosion inhibitors on the corrosion of pipeline tops. Background technique [0002] The top corrosion of pipelines transporting high temperature and high pressure multiphase medium is a common phenomenon. For example, oil and natural gas contain a certain amount of moisture in the process of oil and gas in...

AI Technical Summary

Problems solved by technology

At present, there is no simulated experimental device for corrosion at the top of the pipeline, which limits the research on the mechanism and law of this corrosion phenomenon, and cannot effectively evaluate the corrosion inhibition efficiency of corrosion inhibitors that inhibit or prevent corrosion at the top of the pipeline.

In the previous work, the method of hanging the metal sample in the atmosphere of the high-temperature and high-pressure autoclave was used to carry out the simulated experimental research on the corrosion of the top of the pipeline. The condensed water on the sample is very little, and the sample is still, so it is not good to simulate the corrosion of the top of the pipe caused by the flowing corrosive medium inside the pipe.
