Zusammenfassung: | The present invention relates to a test system and a test method for stress corrosion cracking. The test system for stress corrosion cracking in accordance with an embodiment of the present invention comprises: a reaction tank (10) having a specimen (S) arranged inside; an extender and compressor (20) for extending or compressing a specimen (S); an aqueous solution storage tank (30) for storing the aqueous solution of sodium chloride (NaCl); an oxygen supply unit (40) for supplying oxygen(3) into the reaction tank (10) so that the oxygen (3) can be dissolved in the aqueous solution of sodium chloride (1) to generate test water (5); a circulation pump (50) for adjusting pressure by pressurizing the test water (5) discharged from the reaction tank (10); and a circulation conduit (60) for connecting the reaction tank (10) and the circulation pump (50) so that the test water (5) inside the reaction tank (10) can flow through the circulation pump (50) and return to the reaction tank (10).
본 발명은 응력부식균열 시험 시스템 및 시험 방법에 관한 것으로, 본 발명의 실시예에 따른 응력부식균열 시험 시스템은 내부에 시편(S)이 배치되는 반응조(10), 시편(S)을 인장 또는 압축시키는 인장압축기(20), 염화나트륨(NaCl) 수용액을 저장하는 수용액 저장조(30), 염화나트륨 수용액(1)에 산소(3)가 용해되어 실험수(5)가 생성되도록, 산소(3)를 반응조(10) 내부로 공급하는 산소 공급부(40), 반응조(10)로부터 배출된 실험수(5)를 가압하여 압력을 조절하는 순환펌프(50), 및 반응조(10) 내부의 실험수(5)가 순환펌프(50)를 관류하여 다시 반응조(10)로 복귀되도록 반응조(10)와 순환펌프(50)를 연결하는 순환관로(60)를 포함한다. |
