APPARATUS FOR MEASURING PIPELINE CORROSION Russian patent published in 2012 - IPC G01N17/00 

FIELD: chemistry.

SUBSTANCE: apparatus for measuring pipeline corrosion has a straight housing with a lateral cylindrical boss lying at an angle. The apparatus also has a cover with an inner protrusion and a sealing gasket. A plug, having a hole and made from electrically insulating material with a diameter equal to the inner diameter of the cover, is tightly fitted before the inner protrusion flush with the end of the cover. A square-shaped corrosion test metal plate with side dimension 0.8-0.9 times the inner diameter of the lateral boss is mounted at the centre of the plug. The corrosion test plate has a leg in the middle of the side facing the plug, having a width of 3-5 mm and length of 2-4 mm greater than the thickness of the plug. The corrosion test plate is placed such that its side surface is parallel to the stream of the flowing liquid.

EFFECT: design of an apparatus which enables to reliably determine pipeline corrosion and which is easy to mount into the pipeline.
