Embodiment 1

[0032] Select a pipe sample of appropriate specifications, measure its original size, quality, etc., find out the various physical parameters used in the calculation, and then install the sample on the device to start the test. During the test, pay attention to observe and record the temperature of the medium, the flow rate, the total amount of the medium in the water storage tank, the change of the surface state of the sample, etc. Due to the existence of evaporation, it is necessary to replenish the medium in the water storage tank in time. After the test period is over, remove the sample according to the "Preparation, Cleaning and Evaluation of Corrosion Samples" standard, clean, weigh and calculate, and use various tissue performance analysis instruments for analysis, and finally obtain the erosion corrosion resistance data of the material. This example Only a schematic illustration is given for the results of the annualized corrosion rate. The specific parameters of the t...

Abstract

The invention relates to an erosion corrosion test device of a seawater piping system metal member, comprising a fluoroplastic centrifugal pump and a water storage tank, wherein the inner side wall of the water storage tank is provided with a cooling system; the inlet of the fluoroplastic centrifugal pump is connected with the water storage tank, and the outlet main line of the fluoroplastic centrifugal pump is connected with a plurality of parallel-connected working pipelines; each working pipeline is sequentially connected in series with a flow regulating valve, a vortex street flowmeter and a working pipe section; the outlet ends of the plurality of parallel-connected working pipelines are communicated with the water storage tank through loops; the outlet main line of the fluoroplastic centrifugal pump is also provided with a by-pass; the by-pass is communicated to the water storage tank; and the working pipe section is also electrically connected with an electrochemical test device. The erosion corrosion test device can realize the erosion corrosion resistant property tests of different pipe samples under approximately completely consistent test conditions of a same medium, same temperature, same flow velocity, and the like and can also be used for researching the erosion corrosion resistant property of a same material under the conditions of different mediums and flow velocities.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for erosion and corrosion of metal components of seawater piping systems. Background technique [0002] Scouring and corrosion are common in marine engineering. The degradation and erosion caused by scouring and corrosion cause damage to marine equipment such as pipes, containers, heat exchangers, etc., which increases production costs, delays, and increases maintenance costs. In severe cases, it will cause major safety hazards. ACCIDENT. Erosion corrosion is a kind of local corrosion with great harm, which is much more serious than simple corrosion and simple mechanical wear. When the equipment is subjected to erosion corrosion, it will accelerate its damage, so that the service life of the equipment will be greatly shortened. To mitigate these problems, it is of great practical value to test in advance the erosion corrosion resistance of various materials under conditions close t...
