Mubyerekeranye nubwubatsi nubwubatsi bwa gisivili, ibikoresho byakoreshejwe bigira ingaruka zikomeye kuramba numutekano wumushinga. Kimwe muri ibyo bikoresho byubahwa cyane mu nganda ni ibirundo by'ibyuma, cyane cyane byujuje ubuziranenge bwa ASTM A252. Gusobanukirwa iki gipimo ningirakamaro kubashakashatsi, abashoramari, n'abashinzwe imishinga kimwe, kuko byemeza ko ibikoresho byakoreshejwe byujuje ubuziranenge nibikorwa.
Ibipimo bya ASTM A252 bitwikiriye silindrike nominal urukuta rw'ibyuma bya pile byumwihariko. Ibirundo byashizweho kugirango bikoreshwe nkabanyamuryango bahoraho bitwaje imitwaro cyangwa nkamazu yo guteramo ibirundo bya beto. Ubu buryo bwinshi butuma bagira uruhare runini mubikorwa bitandukanye byubwubatsi, harimo urufatiro rwibiraro, inyubako, nizindi nyubako zisaba urufatiro rwimbitse.
Imwe mu ngingo zingenzi zaASTM A252gisanzwe nicyo cyibanda kumiterere yicyuma gikoreshwa mubirundo. Ibipimo ngenderwaho byerekana ibisabwa kugirango imbaraga zitange umusaruro, imbaraga zingana, no kuramba kugirango ibyuma bishobore kwihanganira imizigo hamwe nibibazo bishobora guhura nabyo mubuzima bwakazi. Mubyongeyeho, ibipimo byerekana uburyo bwemewe bwo kugerageza iyi mitungo, bitanga urwego rwo kwemeza ubuziranenge.
Ku bijyanye n’inganda, ibigo bitanga ibirundo byibyuma bigomba kubahiriza igipimo cya ASTM A252 kugirango ibicuruzwa byabo byizewe kandi bifite umutekano mukubaka. Kurugero, isosiyete ifite umutungo wose wa miliyoni 680 z'amafaranga y'u Rwanda n'abakozi 680 itanga toni 400.000 z'imiyoboro y'icyuma izenguruka buri mwaka ifite agaciro ka miliyari 1.8. Ibigo nkibi bigira uruhare runini murwego rwo gutanga, bitanga ibikoresho byiza byujuje ubuziranenge bwinganda.
Igikorwa cyo kubyaza umusaruroikirundo cy'icyumaikubiyemo intambwe nyinshi, zirimo guhitamo ibikoresho fatizo, gukora imiyoboro no gukingira ibintu. Buri ntambwe igomba kugenzurwa cyane kugirango hubahirizwe ibipimo bya ASTM A252. Kurugero, ibyuma byakoreshejwe bigomba guturuka kubatanga bazwi bashobora gutanga ibyemezo byurusyo byerekana ko ibikoresho byujuje ibisabwa.
Byongeye kandi, ASTM A252 isanzwe ikubiyemo gusudira no guhimba bikoreshwa mugukora ibirundo. Tekinike yo gusudira neza ningirakamaro kugirango igumane uburinganire bwimiterere yibirundo, kandi ibipimo bitanga umurongo ngenderwaho kugirango weld ikorwe neza kandi igenzurwe neza.
Muri rusange, igipimo cya ASTM A252 nigisobanuro cyingenzi kubakozi bose bakora mubikorwa byubwubatsi, cyane cyane mubijyanye no gukoresha ibirundo byibyuma. Gusobanukirwa ibisabwa niki gipimo bifasha kwemeza ko imishinga iramba kandi ikoresha ibikoresho bizahagarara mugihe cyigihe. Ibigo bitanga ibyo bikoresho, nkibyavuzwe mbere, bigira uruhare runini mu nganda bitanga ibicuruzwa byiza byujuje ubuziranenge. Mugihe imishinga yubwubatsi ikomeje gutera imbere, gukomeza kugezwaho ibipimo nka ASTM A252 nibyingenzi kugirango umuntu atsinde murwego.
