Two<br \/>\nphenomena regarding the pipes coating deterioration have been recognized: corrosion and abrasion. The<br \/>\ncorrosion tests performed on different coatings in a neutral salt spray for up to 1000 hours indicate that this method<br \/>\nis applicable for a rough external surface of centrifugally casted ductile iron pipes. The abrasion tests have been<br \/>\nperformed manually, using a grinding paper 1000#, due to an irregular profile of the external pipe surface<br \/>\ntransferred from the casting mold. It helped to obtain \u201cspotted\u201d sections, which were further microscopically<br \/>\nanalyzed (layer-by-layer). The last procedure, however not standardized, could be in some regards more convenient<br \/>\ncomparing to traditional cross-sections.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[1905,1908,1907,1906],"tematyka":[387],"class_list":["post-15916","artykul","type-artykul","status-publish","hentry","tag-oxide-scale","tag-sealing-paint","tag-thermal-sprayed-coating","tag-water-supply-pipes","tematyka-water-supply-and-sewage-system","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["AGNIESZKA KOCHMA\u0143SKA","ANNA WASSILKOWSKA","WOJCIECH D\u0104BROWSKI"],"ptb_artykul_text_2":"10.36119\/15.2020.8.5","ptb_artykul_numer_miesi_cznika":"8\/2020 Instal p. 29-32","ptb_artykul_info_autor":"dr hab. in\u017c.
