20G:GB5310-95 simbi yakagamuchirwa (yekunze inoenderana nedhigirii: ST45.8 yeGermany, STB42 yeJapan, United States SA106B), ndiyo pombi yesimbi yebhoyila inoshandiswa zvakanyanya, maumbirwo emakemikari uye hunhu hwemakanika uye 20 plate yakafanana. Simbi ine simba rakati patembiricha yemukamuri uye tembiricha yepamusoro yepakati, kabhoni yakaderera, purasitiki iri nani uye kusimba, mashandiro ayo ekupisa nekutonhora uye welding akanaka. Inonyanya kushandiswa mukugadzira ma "boiler fittings" ane kumanikidzwa kwakanyanya uye akakwira, "low temperature section superheater", "reheater", "economizer" uye "water wall", nezvimwewo. Sepombi yepombi diki ine dhayamita ≤500℃ heating surface, uye "water wall pipe", "economizer tube", "large dayameter pipe" ine steam pipe, "collection box" (economizer, water wall, low temperature superheater uye reheater coupling box), "medium temperature ≤450℃ pipeline accessories". Nekuti simbi yekabhoni ichaburitsa graphitization mukushanda kwenguva refu pamusoro pe450℃, saka tembiricha yepamusoro yebasa refu yepombi yekudziya inongogumira pasi pe450℃. Simbi iri muchikamu ichi chekupisa, simba rayo rinogona kusangana nezvinodiwa zve superheater ne steam pipeline, uye ine resistance yakanaka ye oxidation, plasticity, kuoma, welding properties uye mamwe maitiro ekugadzirisa anotonhora uye anopisa akanaka kwazvo, anoshandiswa zvakanyanya. Zvikamu zvesimbi zvinoshandiswa muvira reIran (zvichireva seti imwe chete) ipombi yekupinda mvura (28 matani), pombi yekupinda mvura (20 matani), pombi yekubatanidza steam (26 matani), mudziyo we economizer (8 matani), uye system yekuderedza mvura (5 matani), uye zvimwe zvinoshandiswa sesimbi yakatsetseka uye zvinhu zve derrick (anenge matani 86).

Sa-210c (25MnG) : Nhamba yesimbi iri muASME SA-210standard. Ichubhu diki yesimbi yecarbon manganese ine dhayamita yemabhaira nema superheater, uye simbi ine simba rinopisa ine chimiro chemaparera. Muna 1995, yakasimwa kuita GB5310 ikazotumidzwa zita rekuti 25MnG. Kuumbwa kwayo kwemakemikari kuri nyore, kunze kwehuwandu hwekabhoni nemanganese hwakakwira, zvimwe zvakafanana ne20G, saka simba remubereko rakakwira ne20% kupfuura 20G, uye purasitiki nekusimba kwakafanana ne20G. Maitiro ekugadzira simbi ari nyore uye mashandiro ayo ekutonhora nekupisa akanaka. Kushandisa panzvimbo pe20G, kunogona kuderedza ukobvu hwemadziro, kuderedza huwandu hwezvinhu, asiwo kunogona kuvandudza kutamiswa kwekupisa kwebhaira. Zvikamu zvayo zvekushandisa uye tembiricha yekushandisa zvakafanana ne20G, zvinonyanya kushandiswa pakupisa kwekushanda pasi pe500℃ water wall, economizer, low temperature superheater nezvimwe zvikamu.
Sa-106c: Inhamba yesimbi iri muASME SA-106standard. Ichubhu yesimbi yecarbon-manganese inoshandiswa pakubikira mabhoyila makuru nema superheaters anodziya zvakanyanya. Makemikari ayo ari nyore, akafanana nesimbi yecarbon ye20G, asi huwandu hwekabhoni nemanganese hwakakwira, saka simba rayo rekugadzira rakakwirira ne12% kupfuura 20G, uye kuomarara kwayo hakuna kuipa. Maitiro ekugadzira simbi ari nyore uye mashandiro ayo anotonhora uye anopisa akanaka. Kushandisa panzvimbo pe20G yekugadzira collector (economizer, water cooling wall, low temperature superheater uye reheater coupling box), ukobvu hwemadziro hunogona kuderedzwa neinenge 10%, izvo zvisingangogone kuchengetedza mari yezvinhu chete, asiwo kuderedza basa rekuwelding, uye kuvandudza musiyano wekushushikana kana bhokisi re coupling ratanga.
15Mo3 (15MoG): Ipombi yesimbi iri muDIN17175 standard. Ichubhu yesimbi yecarbon molybdenum ine dhayamita diki yekubikira nesuperheater, uye simbi ine simba rinopisa remhando yepearlescent. Muna 1995, yakasimwa kuita GB5310 ikazotumidzwa zita rekuti 15MoG. Kuumbwa kwayo kwemakemikari kuri nyore, asi ine molybdenum, saka ine simba rinopisa riri nani pane simbi yecarbon uku ichiramba ichiita zvakafanana nesimbi yecarbon. Nekuda kwekushanda kwayo kwakanaka, mutengo wakaderera, yave ichishandiswa zvakanyanya pasi rose. Zvisinei, simbi iyi ine katsika kekuita graphitization mushure mekushanda kwenguva refu pakupisa kwakanyanya, saka tembiricha yayo yekushanda inofanira kudzorwa pasi pe510℃, uye huwandu hweAl inowedzerwa mukunyungudutsa hunofanira kuganhurirwa pakudzora nekunonotsa maitiro egraphitization. Chubhu iyi yesimbi inonyanya kushandiswa kune superheater ine tembiricha yakaderera uye reheater ine tembiricha yakaderera. Tembiricha yemadziro iri pasi pe510℃. Kuumbwa kwayo kwemakemikari C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Simba rakajairika σs≥270-285, σb≥450-600 MPa; Plastiki delta 22 kana kupfuura.
