Corrosion test probe assembly
Abstract
Abstract A corrosion test proble assembly formed of a pipe-plug base, a cylindrical insulator member and metallic electrodes. The rigid insulator member is slideably positioned in a cylindrical passageway and secured in longitudinal inward engagement with a shoulder in the body. Electrical conductors are secured in the member and extend from one end into a cavity in the body to connect by flexible leads to an external circuit connector and from the other end to receive, by threaded interconnection, metallic electrodes which can be immersed within a corrodant. A resilient annular seal resides in a circumferential groove in the member and forms a fluid-tight seal between the member and the body. Insulating fluid seals about the conductors are engaged axially in fluid-tightness between the member and the electrodes. The probe assembly is fabricated with easily interfitting parts and may be field-repaired to correct defects in the resilient seal or replacement of the insulator member.
