ABSTRACT:
A flush mounted probe for corrosion testing by assembling into a nipple secured to a pipeline. The nipple is of conventional design such as employed in hot tapping installations. The probe is arranged upon assembly within the nipple to place a plurality of planar-surfaced metallic electrodes in substantially parallel alignment with the inner surface of the sidewall of the pipeline. The probe is arranged by its construction for installation and removal in the same manner as blind plugs and other assessories using the hot tapping equipment. No special tools or parts are required to install and remove the present probe, even under extremely elevated pressure conditions in a pipeline.
