Loaʻa i ke kila kahi ikaika i ka mahana o ka lumi a me ka mahana kiʻekiʻe waena, haʻahaʻa ka nui o ke kalapona, ʻoi aku ka maikaʻi o ka plasticity a me ka paʻakikī, a maikaʻi kona hana wela a me ke anu a me ka hana kuʻi. Hoʻohana nui ʻia ia i ka hana ʻana i nā mea hoʻopili paila no ke kaomi kiʻekiʻe a me nā palena kiʻekiʻe, ka superheater ʻāpana mahana haʻahaʻa, ka reheater, ka economizer a me ka paia wai, a pēlā aku. E like me ka paipu paia wela wela liʻiliʻi ≤500℃, a me ka paipu paia wai, ka paipu economizer, ka paipu paia wela wela nui ≤450℃, ka pahu hōʻiliʻili (economizer, paia wai, superheater mahana haʻahaʻa a me ka pahu hoʻopili reheater), nā mea pono paipu mahana waena ≤450℃. No ka mea, e hana ke kila kalapona i ka graphitization i ka hana lōʻihi ma luna o 450 ℃, no laila ʻoi aku ka maikaʻi o ka palena ʻana o ka mahana lawelawe lōʻihi o ka paipu ʻili hoʻomehana ma lalo o 450 ℃. ʻO ke kila i loko o kēia pae mahana, hiki i kona ikaika ke hoʻokō i nā koi o ka superheater a me ka pipeline mahu, a he kūpaʻa maikaʻi kona i ka oxidation, plasticity, toughness, nā waiwai welding a me nā waiwai hana anu a wela ʻē aʻe he maikaʻi loa, hoʻohana nui ʻia. ʻO nā ʻāpana o ke kila i hoʻohana ʻia i loko o ka umu Iranian (e pili ana i kahi set hoʻokahi) ʻo ia ka paipu komo wai (28 tons), ka paipu komo wai (20 tons), ka paipu hoʻohui mahu (26 tons), ka pahu economizer (8 tons), a me ka ʻōnaehana hōʻemi wai (5 tons), a ʻo ke koena e hoʻohana ʻia e like me ke kila pālahalaha a me nā mea derrick (ma kahi o 86 tons).

Sa-210c (25MnG): Helu kila i lokoASME SA-210kūlana. He paipu liʻiliʻi ia o ke kila manganese kalapona no nā paila a me nā superheaters, a he kila ikaika wela me ke ʻano momi. I ka makahiki 1995, ua hoʻoili ʻia i GB5310 a kapa ʻia ʻo 25MnG. He maʻalahi kona ʻano kemika, koe wale nō ka nui o ke kalapona a me ka manganese, ua like ke koena me 20G, no laila ʻoi aku ka ikaika o ka hua ma kahi o 20% ma mua o 20G, a ua like ka plastic a me ka paʻakikī me 20G. He maʻalahi ke kaʻina hana o ke kila a maikaʻi kāna hana anu a wela. ʻO ka hoʻohana ʻana ma kahi o 20G, hiki ke hoʻemi i ka mānoanoa o ka paia, hoʻemi i ka nui o nā mea, akā hiki nō hoʻi ke hoʻomaikaʻi i ka hoʻoili wela o ka paila. ʻO kona hoʻohana ʻana i nā ʻāpana a me ka mahana hoʻohana e like me 20G, hoʻohana nui ʻia no ka mahana hana ma lalo o 500℃ paia wai, economizer, superheater mahana haʻahaʻa a me nā ʻāpana ʻē aʻe.
Sa-106c: He helu kila ia maASME SA-106kūlana. He paipu kila kalapona-manganese ia no nā paila nui a me nā superheaters me ke anawaena kiʻekiʻe. He maʻalahi kona ʻano kemika, like me ke kila kalapona 20G, akā ʻoi aku ka nui o ke kalapona a me ka manganese, no laila ʻoi aku ka ikaika o kona hua ma kahi o 12% ma mua o 20G, a ʻaʻole maikaʻi ʻole ka palakika, paʻakikī. He maʻalahi ke kaʻina hana o ke kila a maikaʻi kāna hana anu a wela. Ke hoʻohana nei iā ia ma kahi o ka mea hōʻiliʻili hana 20G (economizer, paia hoʻoluʻu wai, superheater wela haʻahaʻa a me ka pahu hoʻopili reheater), hiki ke hoʻemi ʻia ka mānoanoa o ka paia ma kahi o 10%, ʻaʻole hiki ke mālama wale i ke kumukūʻai o nā mea, akā e hōʻemi pū i ka ukana hana wili, a hoʻomaikaʻi i ka ʻokoʻa o ke kaumaha ke hoʻomaka ka pahu hoʻopili.
15Mo3 (15MoG) : He paipu kila ia ma ke kūlana DIN17175. He paipu kila kalapona molybdenum liʻiliʻi ke anawaena no ka paila a me ka superheater, a he kila ikaika wela ʻano pearlescent. I ka makahiki 1995, ua hoʻoili ʻia i GB5310 a kapa ʻia ʻo 15MoG. He maʻalahi kona ʻano kemika, akā aia ka molybdenum, no laila ʻoi aku ka maikaʻi o ka ikaika wela ma mua o ke kila kalapona me ka mālama ʻana i ka hana hana like me ke kila kalapona. Ma muli o kāna hana maikaʻi, ke kumu kūʻai haʻahaʻa, ua hoʻohana nui ʻia ma ka honua. Eia nō naʻe, he ʻano koʻikoʻi ke kila i ka graphitization ma hope o ka hana lōʻihi ma ke kiʻekiʻe o ka mahana, no laila pono e hoʻomalu ʻia kona mahana hana ma lalo o 510 ℃, a ʻo ka nui o Al i hoʻohui ʻia i ka hoʻoheheʻe ʻana e kaupalena ʻia i ka kaohi a me ka hoʻopaneʻe ʻana i ke kaʻina hana graphitization. Hoʻohana nui ʻia kēia paipu kila no ka superheater haʻahaʻa haʻahaʻa a me ka reheater haʻahaʻa haʻahaʻa. Aia ka mahana o ka paia ma lalo o 510 ℃. ʻO kona ʻano kemika C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; ʻO ka pae ikaika maʻamau σs≥270-285, σb≥450-600 MPa; ʻO ka plastic delta 22 a ʻoi aku paha.
