Description
The present invention relates to a corrosion test apparatus capable of measuring the degree of corrosion of the stainless steel tube-tube welding part for cooling seawater heat exchanger, and more particularly, by adjusting the type and temperature, flow rate and flow rate of the test solution, The present invention relates to a corrosion test apparatus that can shorten the test time by measuring the degree of corrosion of a specimen under more severe conditions.
The stainless steel tube-tube welds for cooling seawater heat exchangers may have lower corrosion resistance than the base material because they cannot be heat treated after the welding process. For this reason, it is difficult to grasp the degree of corrosion of the stainless steel tube-tube welding part for a cooling seawater heat exchanger by the simple corrosion test for the conventional base material.
Therefore, considering the use environment of stainless steel tube-tube plate welding part for cooling seawater heat exchanger, the test should be performed to measure the corrosion degree of the welding part. It is necessary to shorten the test time by measuring the degree of corrosion of the specimen.
An object of the present invention is to adjust the type and temperature, flow rate and flow rate of the test solution in order to solve the conventional problems as described above, the specimen for the harsh conditions than the actual use environment of the stainless steel tube-tube plate welding part for cooling seawater heat exchanger The purpose is to provide a corrosion test apparatus that can reduce the test time by measuring the degree of corrosion.
In order to solve the above technical problem, the present invention comprises a storage tank for receiving a test solution, a temperature control device for controlling the temperature of the test solution, a supply pump for controlling the flow rate and flow rate of the test solution, The degree of corrosion of the specimen as a function of temperature, flow rate and flow rate should be determined.
As described above, the corrosion test apparatus according to the present invention includes a storage tank containing a test solution, a temperature control device controlling a temperature of the test solution, a test chamber having a specimen, a supply connecting the storage tank and the test chamber. And a supply pump mounted to the supply pipe, wherein the temperature control device controls the temperature of the test solution, and the supply pump controls the flow rate of the test solution, thereby providing a stainless steel pipe-tube welding part for cooling seawater heat exchanger. The test time can be shortened by measuring the corrosion of the specimen under harsher conditions than the actual use environment.
