METHOD OF TESTING CORROSION OF INTERNAL SURFACES OF PIPELINES AND CYLINDRICAL CONTAINERS

摘要

FIELD: evaluation of speed of corrosion of internal; surface of pipelines. ^ SUBSTANCE: specimen-witness, made in form of flat plate, is introduced into tested object through special openings; specimen is fixed onto guiding rod. Plate is placed onto tested surface after its edges reach internal surface of object by means of application of calculating deforming strength to plate from side of guiding rod till plate completely touches the internal surface of tested object. Specimen-witness is kept in corrosion-aggressive medium and then it is withdrawn. ^ EFFECT: improved truth of testing of corrosion. ^ 2 cl, 1 dwg
