20G:GB5310-95 te rino paerewa whakaaetanga (koeke rite ke: ST45.8 o Tiamana, STB42 o Hapani, te United States SA106B), ko te putorino rino kora te tino whakamahia, te hanganga matū me nga taonga miihini me te pereti 20 he rite tonu. He kaha te kaha o te rino i te pāmahana rūma me te pāmahana teitei, te iti o te waro, te pai o te kirihou me te uaua, he pai te hanga o te wera me te makariri me te pai o te mahi. Kei te nuinga whakamahia te reira i roto i te hanga o te pēhanga teitei, me te teitei tawhā o te kōhua ​​taputapu, iti pāmahana wāhanga superheater, reheater, economizer me te taiepa wai, me ētahi atu Pērā i iti diameter paipa taiepa pāmahana ≤500 ℃ whakawera mata paipa, me te paipa taiepa wai, ngongo economizer, nui te diameter paipa taiepa pāmahana ≤450 ℃ mamaoa paipa, pouaka kohinga (economizer, taiepa wai, iti pāmahana superheater me reheater pouaka hononga), pāmahana reo ≤450℃ taputapu paipa. Na te mea ka whakaputa te waro maitai i te graphitization i roto i te mahi mo te wa roa i runga ake i te 450 ℃, no reira ko te roa o te roanga o te ratonga morahi o te putorino mata whakawera he pai ake ki raro i te 450 ℃. Ko te maitai i roto i tenei awhe pāmahana, ka taea e tona kaha te whakatutuki i nga whakaritenga o te superheater me te pipeline mamaoa, me te pai o te aukati o te waikura, te kirihou, te uaua, nga taonga whakahiato me etahi atu momo tukatuka makariri me te wera he tino pai, he nui te whakamahi. Ko nga wahanga o te maitai e whakamahia ana i roto i te oumu o Iran (e tohu ana mo te huinga kotahi) ko te paipa uru wai (28 tons), te paipa whakauru wai (20 tons), te paipa hono mamao (26 tons), te ipu economizer (8). ton), me te punaha whakaheke wai (5 tone), a ko te toenga ka whakamahia hei taputapu rino papatahi me nga taonga derrick (tata ki te 86 tone).

Sa-210c (25MnG) : Tau maitai i rotoASME SA-210paerewa. He ngongo iti te diameter o te waro konupora maitai mo nga kohua me te wera nui, me te maitai kaha wera me te ahua peara. I te tau 1995, i whakawhitia ki GB5310 ka whakaingoatia ko 25MnG. He mea ngawari tana hanganga matū, engari mo te teitei ake o te waro me te konupora, ko te toenga he rite ki te 20G, no reira ko te kaha o te tuku he 20% teitei ake i te 20G, me te kirihou me te pakari he rite ki te 20G. He ngawari te mahi hanga o te maitai, he pai hoki tana mahi mahi makariri me te wera. Ma te whakamahi hei utu mo te 20G, ka taea te whakaiti i te matotoru o te pakitara, te whakaiti i te nui o nga rauemi, engari ka taea hoki te whakapai ake i te whakawhiti wera o te kohu. Ko ona waahanga whakamahi me te whakamahi i te pāmahana he rite tonu ki te 20G, te nuinga e whakamahia ana mo te mahi i raro i te 500 ℃ pakitara wai, economizer, iti pāmahana superheater me etahi atu waahanga.
Sa-106c: He nama rino kei rotoASME SA-106paerewa. He ngongo maitai waro-konupora mo nga paera teitei-diameter me nga whakamahana nui. He ngawari tona hanganga matū, he rite ki te 20G waro maitai, engari ko te ihirangi o te waro me te konupora he teitei ake, no reira ko te kaha o te kaha ki te 12% teitei ake i te 20G, me te kirihou, kaore i te kino. He ngawari te mahi hanga o te maitai, he pai hoki tana mahi mahi makariri me te wera. Ma te whakamahi hei utu mo te kaikohikohi hangahanga 20G (he kaikohikohi, he pakitara whakamahana wai, he wera wera iti me te pouaka honoa whakamahana), ka taea te whakaheke i te matotoru o te pakitara mo te 10%, kaore e taea te penapena i nga utu rauemi, engari ka whakaiti ano i te taumaha o te mahi, me te whakapai ake i te rereketanga o te ahotea ina timata te pouaka hono.
15Mo3 (15MoG) : He paipa maitai i roto i te paerewa DIN17175. He iti te diameter waro molybdenum ngongo maitai mo te kohu me te superheater, me te momo pearlescent maitai kaha wera. I te tau 1995, i whakawhitia ki GB5310 ka whakaingoatia ko 15MoG. He maamaa te hanganga matū, engari he molybdenum kei roto, na reira he pai ake te kaha o te waiariki i te waro maitai i te wa e mau tonu ana te mahinga o te mahi ki te waro maitai. Na te pai o tana mahi, te utu iti, kua whakamahia nuitia i te ao. Engari, ko te maitai he kaha ki te graphitization i muri i te mahi mo te wa roa i te teitei o te wera, na reira me whakahaere tona pāmahana whakahaere i raro i te 510 ℃, me te nui o te Al kua tapiritia ki te whakarewatanga me iti ki te whakahaere me te whakaroa i te tukanga graphitization. Ko te nuinga o tenei ngongo maitai e whakamahia ana mo te wera wera iti me te whakamahana wera iti. Ko te pāmahana pakitara kei raro i te 510 ℃. Ko tana hanganga matū C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Ko te taumata kaha noa σs≥270-285, σb≥450-600 MPa; Delta kirihou 22 teitei ake ranei.
