GLASS TEST VESSEL FOR HIDROGEN INDUCED CRACKING TEST WITH SQUARE SHUT TYPE

摘要

A sealable square glass specimen vessel for hydrogen induced cracking test can improve the accuracy of test since the test tub is made of glass in order to prevent the reaction with the test solution fundamentally. A sealable square glass specimen vessel(A) with a transparent square body made of glass includes a test tub(2) in which a stepped projection(22) is formed on the outer circumference of an upper opening, a receiving part is formed inside, a gas inlet and a gas outlet(7) are formed on the outer side, and a solution outlet(3) is formed on the lower side; a cover(4) installed at the opening of the test tub, with a contact unit(42) corresponding to the stepped projection; a fixing unit(9) which is installed on the combined stepped projection and contact unit; a connecting unit(200) installed on the cover; and a solution collecting unit(6) comprising a suction tube which is penetrated through the connecting unit and inserted to the test tub.
