Methods for protecting corrosion of the inner surface of steel vitrified pipes during welding

ABSTRACT

In work corrosion problems of welded steel vitrified pipelines and ways of their protection under the action of high mineral water with hydrogen sulphide (water conduits) of oil-compressor stations are considered. It is established that in order to eliminate the harmful effect of microalloying by boron of the welding seam, it is recommended to use the mentioned above welded joints of such pipelines as well as their repair. In view of the presence of a glass coating, it is recommended that extreme safety precautions be taken when installing such pipelines, in order to avoid disruption of the continuity of the glass coating.
