20G:GB5310-95 ibyuma bisanzwe byemerwa (urwego rujyanye n’amahanga: ST45.8 yo mu Budage, STB42 y’Ubuyapani, Amerika SA106B), ni umuyoboro w’icyuma gikoreshwa cyane, ibikoresho bya shimi hamwe nubukanishi hamwe nisahani 20 ni bimwe. Icyuma gifite imbaraga runaka mubushyuhe bwicyumba hamwe nubushyuhe bwo hejuru buringaniye, karuboni nkeya, plastike nziza nubukomere, uburyo bushyushye nubukonje hamwe no gusudira nibyiza. Ikoreshwa cyane cyane mugukora umuvuduko mwinshi hamwe nibipimo bihanitse byo gutekesha ibyuka, ubushyuhe buke bwikirenga superheater, reheater, economizer nurukuta rwamazi, nibindi nkubushyuhe buke bwa diameter umuyoboro wubushyuhe ≤500 ℃ umuyoboro wubushuhe, hamwe numuyoboro wurukuta rwamazi, umuyoboro wubukungu, diameter nini ya diameter yubushyuhe ≤450 pip umuyoboro wamazi, agasanduku kegeranya (economizer, urukuta rwamazi, ubushyuhe buke bwa superheater hamwe nisanduku yo guhuza reheater), ubushyuhe bwo hagati ≤450 accessories ibikoresho byumuyoboro. Kuberako ibyuma bya karubone bizatanga igishushanyo mubikorwa birebire birenga 450 ℃, bityo ubushyuhe bwigihe kirekire bwa serivisi yubushyuhe bwo hejuru yubushyuhe bugarukira munsi ya 450 ℃. Icyuma muri ubu bushyuhe, imbaraga zacyo zirashobora kuzuza ibisabwa byumuyoboro wa superheater hamwe na parike, kandi bifite imbaraga zo kurwanya okiside, plastike, gukomera, gusudira nibindi bikoresho bikonje kandi bishyushye nibyiza cyane, bikoreshwa cyane. Ibice by'ibyuma bikoreshwa mu itanura rya Irani (bivuga iseti imwe) ni umuyoboro w'amazi (toni 28), umuyoboro w'amazi (toni 20), umuyoboro uhuza amavuta (toni 26), ibikoresho by'ubukungu (8 toni), hamwe na sisitemu yo kugabanya amazi (toni 5), naho ibindi bikoreshwa nk'ibyuma bisize hamwe n'ibikoresho bya derrick (hafi toni 86).

Sa-210c (25MnG): Umubare w'icyuma muriASME SA-210bisanzwe. Numuyoboro muto wa diameter yicyuma cya karubone manganese kubiteke na superheater, hamwe nicyuma gishyushye gifite imaragarita. Mu 1995, yatewe muri GB5310 yitwa 25MnG. Ibigize imiti biroroshye, usibye kuba karubone nyinshi na manganese, ibisigaye bisa na 20G, bityo imbaraga zumusaruro zikaba zigera kuri 20% hejuru ya 20G, naho plastike nubukomezi bisa na 20G. Ibikorwa byo gukora ibyuma biroroshye kandi imikorere yayo ikonje kandi ishyushye ni nziza. Kubikoresha aho kuba 20G, birashobora kugabanya ubunini bwurukuta, kugabanya umubare wibikoresho, ariko kandi birashobora kunoza ubushyuhe bwo guteka. Gukoresha ibice no gukoresha ubushyuhe mubyukuri ni kimwe na 20G, bikoreshwa cyane mubushyuhe bwo gukora munsi ya 500 wall urukuta rwamazi, ubukungu, ubushyuhe buke bwubushyuhe nibindi bice.
Sa-106c: Numubare wibyuma muriASME SA-106bisanzwe. Nicyuma cya karubone-manganese kumashanyarazi yubushyuhe bwo hejuru bwa diameter nini na superheater. Ibigize imiti biroroshye, bisa na 20G ibyuma bya karubone, ariko ibirimo karubone na manganese ni byinshi, bityo imbaraga zabyo zikaba ziri hejuru ya 12% hejuru ya 20G, kandi plastike, gukomera ntabwo ari bibi. Ibikorwa byo gukora ibyuma biroroshye kandi imikorere yayo ikonje kandi ishyushye ni nziza. Kubikoresha aho gukoresha 20G ikora inganda (economizer, urukuta rwo gukonjesha amazi, ubushyuhe buke bwa superheater hamwe na agasanduku ka reheater), uburebure bwurukuta burashobora kugabanukaho hafi 10%, ntibishobora kuzigama gusa ibikoresho, ariko kandi bigabanya akazi ko gusudira, kandi utezimbere itandukaniro ryimyitwarire mugihe agasanduku gatangiye.
15Mo3 (15MoG): Numuyoboro wibyuma mubisanzwe DIN17175. Nibikoresho bito bya diameter ya karubone molybdenum ibyuma bya boiler na superheater, nubwoko bwa pearlescent ibyuma bishyushye. Mu 1995, yatewe muri GB5310 yitwa 15MoG. Ibigize imiti biroroshye, ariko birimo molybdenum, bityo ifite imbaraga zumuriro nziza kuruta ibyuma bya karubone mugihe ikomeza imikorere imwe nicyuma cya karubone. Kubera imikorere myiza, igiciro gihenze, yakoreshejwe henshi kwisi. Nyamara, ibyuma bifite imyumvire yo gushushanya nyuma yigihe kirekire ikora mubushyuhe bwinshi, bityo ubushyuhe bwayo bukora bugomba kugenzurwa munsi ya 510 and, kandi umubare wa Al wongeyeho mugushonga ugomba kugarukira kugenzura no gutinza gahunda yo gushushanya. Umuyoboro wibyuma ukoreshwa cyane cyane mubushyuhe buke nubushyuhe buke. Ubushyuhe bwurukuta buri munsi ya 510 ℃. Ibigize imiti C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Urwego rusanzwe rwimbaraga σs≥270-285, σb≥450-600 MPa; Delta ya plastike 22 cyangwa irenga.
