Mu nganda, imiyoboro y'icyuma igira uruhare runini mu gutwara amazi n'imyuka neza. Inganda zitandukanye zisaba ubwoko bwihariye bw'imiyoboro y'icyuma, bitewe n'ibyo zikeneye n'imimerere yazo yihariye. Uyu munsi, turareba neza uburyo ibikoresho bitatu by'ingenzi by'imiyoboro y'icyuma bikora neza: umuyoboro w'icyuma wa ASTM A53 Gr. B, umuyoboro w'icyuma wa ASTM A192, n'umuyoboro w'icyuma wa API 5L Gr. B udakora neza.
ASTM A53 GR.Bumuyoboro w'icyuma wa boiler:
Umuyoboro w'icyuma wa ASTM A53 GR.B ni umuyoboro w'icyuma wo mu rwego rwo hejuru wagenewe gukoreshwa mu bushyuhe bwinshi n'umuvuduko mwinshi mu byuma bishyushya no mu byuma bihindura ubushyuhe. Ukorwa hakoreshejwe ibintu bya karuboni n'ibirunga kugira ngo birambe neza kandi birwanye no kwangirika kw'ingufu. Byongeye kandi, imiyoboro y'icyuma ya ASTM A53 Gr. B ifite karuboni nyinshi ugereranyije n'imiyoboro isanzwe, bigatuma ikomera kandi ikomera.
Umuyoboro wa ASTM A192:
Indi miyoboro myiza cyane y'icyuma ni umuyoboro wa ASTM A192, ukoreshwa cyane cyane mu byuma bishyushya bikoresha umuvuduko mwinshi no mu byuma bihindura ubushyuhe. Umuyoboro wa ASTM A192 wubatswe mu cyuma cyiza cya karuboni gifite imiterere myiza ya mekanike kandi kirwanya neza umuvuduko w'imbere n'inyuma.
Umuyoboro w'icyuma udafite umugozi wa API 5L GR.B:
API 5L GR.B yagenewe gutwara gaze karemano, peteroli n'ibindi bintu bivamo amazi. Imiyoboro y'icyuma idakora neza ni amahitamo akunzwe mu nganda za peteroli na gaze. Iyi miyoboro y'icyuma ifite ubushobozi bwo kurwanya stress ya mekanike na ingese, bigatuma iba nziza cyane mu bihe bigoye.
Kuva kuri boilers kugeza ku miyoboro ikwirakwiza peteroli na gaze, ASTM A53 Gr. Bumuyoboro w'icyuma wa boiler, umuyoboro wa ASTM A192 n'umuyoboro w'icyuma udafite umugozi wa API 5L Gr. B bifite akamaro kadasanzwe mu nganda zitandukanye. Ibi bikoresho by'icyuma byihariye bifite imiterere itangaje nko kurwanya ubushyuhe bwinshi, kurwanya ingese ndetse n'imbaraga nziza za mekanike.
