20G:GB5310Insimbi ejwayelekile yokwamukelwa -95 (ibanga elihambisanayo langaphandle: ST45.8 yaseJalimane, STB42 yaseJapan, i-United States SA106B), iyipayipi lensimbi yebhoyila elisetshenziswa kakhulu, ukwakheka kwamakhemikhali kanye nezakhiwo zemishini kanye nepuleti lama-20 ngokuyisisekelo liyafana. Insimbi inamandla athile ekushiseni kwegumbi kanye nokushisa okuphezulu okuphakathi, okuqukethwe okuphansi kwekhabhoni, ipulasitiki engcono kanye nokuqina, ukusebenza kwayo kokushisa nokubanda kanye nokushisela kuhle. Isetshenziswa kakhulu ekwakhiweni kwemingcele yokucindezela okuphezulu kanye nemingcele ephezulu ye-fittings yebhoyila, i-superheater yesigaba sokushisa okuphansi, i-reheater, i-economizer kanye nodonga lwamanzi, njll. Njengokushisa kodonga lwepayipi elincane ububanzi ≤500℃ ipayipi lokushisa elingaphezulu, kanye nepayipi lodonga lwamanzi, ishubhu le-economizer, izinga lokushisa lodonga lwepayipi elikhulu ububanzi ≤450℃ ipayipi lomusi, ibhokisi lokuqoqa (i-economizer, udonga lwamanzi, i-superheater ephansi yokushisa kanye nebhokisi lokuxhuma i-reheater), izinga lokushisa eliphakathi ≤450℃ izesekeli zepayipi. Ngenxa yokuthi insimbi yekhabhoni izokhiqiza i-graphitization ekusebenzeni kwesikhathi eside ngaphezu kuka-450℃, ngakho-ke izinga lokushisa eliphakeme lesikhathi eside lepayipi lokushisa lingcono kakhulu lilinganiselwe ngaphansi kuka-450℃. Insimbi ekulolu hlu lokushisa, amandla ayo angahlangabezana nezidingo zepayipi le-superheater kanye nele-steam, futhi inokumelana okuhle kwe-oxidation, i-plasticity, ukuqina, izakhiwo zokushisela kanye nezinye izakhiwo zokucubungula ezibandayo nezishisayo zinhle kakhulu, zisetshenziswa kabanzi. Izingxenye zensimbi ezisetshenziswa esithandweni sase-Iranian (esibhekisela kusethi eyodwa) yipayipi lokungena kwamanzi (amathani angu-28), ipayipi lokungena kwamanzi (amathani angu-20), ipayipi lokuxhuma umusi (amathani angu-26), isitsha se-economizer (amathani angu-8), kanye nohlelo lokunciphisa amanzi (amathani angu-5), kanti okunye kusetshenziswa njengensimbi eyisicaba kanye nezinto zokwehlisa (cishe amathani angu-86).

I-Sa-210c (25MnG) : Inombolo yensimbi kuI-ASME SA-210ejwayelekile. Iyipayipi elincane elinobubanzi bensimbi ye-carbon manganese yama-boiler nama-superheater, kanye nensimbi enamandla ashisayo enesimo separele. Ngo-1995, yatshalwa kabusha yaba yi-GB5310 futhi yaqanjwa ngokuthi i-25MnG. Ukwakheka kwayo kwamakhemikhali kulula, ngaphandle kokuqukethwe okuphezulu kwekhabhoni ne-manganese, okunye kufana ne-20G, ngakho-ke amandla okukhiqiza angaba ngu-20% aphezulu kune-20G, kanti ipulasitiki nokuqina kufana ne-20G. Inqubo yokukhiqiza yensimbi ilula futhi ukusebenza kwayo okubandayo nokushisa kuhle. Ukuyisebenzisa esikhundleni se-20G, kunganciphisa ukujiya kodonga, kunciphise inani lezinto zokwakha, kodwa futhi kungathuthukisa ukudluliselwa kokushisa kwebhoyila. Izingxenye zayo zokusetshenziswa kanye nokushisa kokusetshenziswa kufana kakhulu ne-20G, esetshenziselwa kakhulu izinga lokushisa lokusebenza ngaphansi kodonga lwamanzi olungaphansi kuka-500℃, i-economizer, i-superheater yokushisa okuphansi nezinye izingxenye.
I-Sa-106c: Yinombolo yensimbi ku-I-ASME SA-106ejwayelekile. Iyipayipi lensimbi ye-carbon-manganese lama-boiler amakhulu anama-superheater ashisa kakhulu. Ukwakheka kwayo kwamakhemikhali kulula, kufana nensimbi yekhabhoni engu-20G, kodwa okuqukethwe yikhabhoni ne-manganese kuphakeme, ngakho-ke amandla ayo okukhiqiza aphakeme cishe ngo-12% kuno-20G, kanti ukuqina kwepulasitiki akukubi. Inqubo yokukhiqiza yensimbi ilula futhi ukusebenza kwayo okubandayo nokushisa kuhle. Ukuyisebenzisa esikhundleni seqoqo lokukhiqiza elingu-20G (i-economizer, udonga lokupholisa amanzi, i-superheater yokushisa okuphansi kanye nebhokisi lokuhlanganisa eliphinda lifudumale), ubukhulu bodonga bungancishiswa cishe ngo-10%, okungeke nje konge izindleko zezinto zokwakha, kodwa futhi kunciphise umthwalo womsebenzi wokushisela, futhi kuthuthukise umehluko wokucindezeleka lapho ibhokisi lokuhlanganisa liqala.
15Mo3 (15MoG): Liyipayipi lensimbi elijwayelekile le-DIN17175. Liyipayipi lensimbi le-carbon molybdenum elincane elinobubanzi obuncane le-boiler kanye ne-superheater, kanye nensimbi enamandla ashisayo yohlobo lwe-pearlescent. Ngo-1995, latshalwa kabusha laba yi-GB5310 futhi laqanjwa ngokuthi yi-15MoG. Ukwakheka kwalo kwamakhemikhali kulula, kodwa liqukethe i-molybdenum, ngakho-ke linamandla okushisa angcono kunensimbi ye-carbon ngenkathi ligcina ukusebenza okufanayo kwenqubo njengensimbi ye-carbon. Ngenxa yokusebenza kwayo okuhle, intengo eshibhile, isetshenziswe kabanzi emhlabeni. Kodwa-ke, insimbi inomkhuba wokusebenzisa i-graphitization ngemuva kokusebenza isikhathi eside ekushiseni okuphezulu, ngakho-ke izinga lokushisa layo lokusebenza kufanele lilawulwe ngaphansi kuka-510℃, futhi inani le-Al elingeziwe ekuncibilikiseni kufanele lilinganiselwe ekulawuleni nasekulibaziseni inqubo ye-graphitization. Leli payipi lensimbi lisetshenziselwa kakhulu i-superheater ephansi yokushisa kanye ne-reheater ephansi yokushisa. Izinga lokushisa lodonga lingaphansi kuka-510℃. Ukwakheka kwayo kwamakhemikhali C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Izinga elijwayelekile lamandla σs≥270-285, σb≥450-600 MPa; I-delta yepulasitiki engu-22 noma ngaphezulu.
