ASTM A53 GR.B Imiyoboro idafite ibyuma
Ibisobanuro bigufi:
ASTM A53 nicyuma cya karubone, ikoreshwa nkibyuma byubatswe cyangwa kumazi yumuvuduko muke. Ibisobanuro bivanze byashyizweho na ASTM International, mubisobanuro ASTM A53 / A53M.
ASTM A53 Igipimo nicyo gikunze kugaragara cyane kumiyoboro yicyuma cya karubone. Umuyoboro wibyuma bya karubone bivuga cyane cyane igice cya karuboni kiri munsi ya 2,11% utarimo ibintu byongeweho nkana bivanga nkibyuma, urwego rwa karubone rurimo ibyuma nimwe murimwe ibintu byingenzi byingenzi kugirango bigire ingaruka kumbaraga zicyuma, ubukana buriyongera, kandi bigabanya guhindagurika, gukomera nubushobozi bwo gusudira.Uretse ibyo, muri rusange harimo na silikoni nkeya, manganese, sulfure, fosifore hiyongereyeho karubone.Ugereranije nubundi bwoko bwibyuma, nubwa mbere, igiciro gito, intera nini yimikorere, umubare munini.Bikwiranye numuvuduko wizina PN ≤ 32.0MPa, ubushyuhe -30-425 ℃ amazi, umwuka, umwuka, hydrogen, ammonia, azote nibikomoka kuri peteroli, nibindi bitangazamakuru.Umuyoboro w'icyuma cya karubone nicyo cyambere cyo gukoresha umubare munini wibikoresho byibanze mu nganda zigezweho.Ibihugu by’inganda ku isi, mu rwego rwo kongera ingufu nyinshi ibyuma bito bito ndetse n’ibyuma bivangwa n’ibyuma, ari na byo byita cyane ku kuzamura ireme no kwagura amoko n’imikoreshereze.Umubare w’ibicuruzwa biva mu bihugu byose biva mu byuma, hafi ya 80%, ntibikoreshwa cyane mu nyubako, ibiraro, gari ya moshi, imodoka, amato n’inganda zose zikora imashini, ariko no mu bucukuzi bwa peteroli bugezweho; inganda, iterambere ry’inyanja, nazo zarakoreshejwe cyane.
