321 Paipu Kulehua
wehewehe
ʻO 321 paipu kila kila he paipu kila i hana ʻia me 321 kila kila.
1:321 paipu kila kila.Hoʻohana ʻia ka paipu kila maʻemaʻe (GB14976-2002) no ka hana ʻana i nā paipu mahu superheated, nā paipu wai paila a me nā paila locomotive o nā hale like ʻole no nā paila haʻahaʻa a me ka haʻahaʻa, nā paipu uwahi nui, nā paipu uwahi liʻiliʻi a me nā paipu brick arch.Kiʻekiʻe kiʻekiʻe kalapona structural kila hot-rolled a me anu (rolled) seamless kila paipu.
2:321 paipu kila kuhiliʻole: hoʻohana nui ʻia no ka hana ʻana i ke kila kila kalapona kiʻekiʻe, ke kila kila kila a me ke kila kila hoʻoheheʻe ʻole i ka wela no nā paipu paila pahu me ke kaomi kiʻekiʻe a ma luna.Hōʻike pinepine ʻia kēia mau paipu boiler i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.E hana, e oxidize a corrode ka paipu ma lalo o ka hana o ke kinoea flue wela kiʻekiʻe a me ka mahu wai, no laila pono ka paipu kila e loaʻa ka ikaika mau loa, kiʻekiʻe oxidation kū'ē, a me ka hoʻonohonoho pono paʻa.
3: 321 mea kila kila kila helu kila: 304321 316 317 310, etc.
4: Alloy structural steel pipes with steel grades of 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.;ke kila kila a me ka wela hoʻohana maʻamau 1Cr18Ni9, 1Cr18Ni11Nb kiʻekiʻe-pressure boiler paipu, ma waho aʻe o ka hōʻoia 'ana i kemika haku mele a me ka mechanical waiwai, pono e ka wai kaomi pakahi no ka hoao ana, he flaring a flattening ho'āʻo e koi 'ia.
5: Hāʻawi ʻia nā paipu kila kila 321 i kahi kūlana wela.Eia kekahi, aia kekahi mau koi no ka microstructure, ka nui o ka palaoa a me ka papa decarburization o ka paipu kila i hoʻopau ʻia.ʻO nā paipu kila maʻemaʻe no ka hoʻoheheʻe honua a me ka hoʻomalu ʻana i ka ʻaila;hoʻohana ʻia nā rig wili no ka ʻike ʻana i ke ʻano o ka pōhaku ma lalo o ka honua, ka wai lepo, ka aila, ke kinoea maoli a me nā kumu waiwai mineral.
ʻAʻole hiki ke hoʻokaʻawale ʻia ka hoʻohana ʻana i ka ʻaila a me ke kinoea maoli mai nā luawai ʻeli.ʻO nā paipu kila maʻemaʻe no ka ʻeli ʻana i ka ʻaila no ka hoʻokele ʻana i ka geological drilling ka mea nui no ka wili ʻana, ʻoi aku ka nui o ka paipu o waho o waho, ka paipu o loko, ka pahu, ka paipu drill a pēlā aku.No ka mea, pono e hele hohonu ka paipu wili i ka hohonu o ka hoʻokumu ʻana o kekahi mau kilomita, 1cr5mo alloy pipe.
6: He paʻakikī loa nā kūlana hana.Hoʻokomo ʻia ka paipu drill i ke koʻikoʻi e like me ke ʻano o ka ʻāʻī ʻana, ka hoʻoemi ʻana, ke kuʻi ʻana, ka torsion a me ka haʻahaʻa ʻole o ka hopena, a ua kau ʻia hoʻi i ka lepo a me ka ʻaʻahu pōhaku.No laila, pono e lawa ka ikaika o ka paipu, ka pa'akikī, ke kū'ē a me ka pa'akikī Impact, 'o ke kila i ho'ohana 'ia no ka paipu kila e hō'ike 'ia ana e "DZ" (geological Chinese Pinyin prefix) a me ka helu ho'okahi e hō'ike i ka helu hua o ke kila.ʻO nā māka kila maʻamau ʻo 45MnB a me 50Mn o DZ45;40Mn2 a me 40Mn2Si o DZ50;40Mn2Mo a me 40MnVB o DZ55;40MnMoB o DZ60, 27MnMoVB o DZ65.Hāʻawi ʻia nā paipu kila ma ke kūlana wela.
ʻO ka ʻokoʻa ma waena o 321 stainless steel a me 304 stainless steel
ʻO ke kila kila 321 ka mea i hoʻololi ʻia o 304 kila kila.ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua, ʻo ia ka piʻi ʻana o ke kalapona ma muli o ka hoʻohui ʻana o ka titanium.ʻO ka hoʻohui ʻana o ka titanium e kōkua i ka pale ʻana i ka ua carbide i ka wā welding a me nā loli wela kiʻekiʻe.
Ma waho aʻe o ka hoʻohui maikaʻi ʻana o ka titanium, loaʻa iā 321 ka nui o nā waiwai like e hana ai i ke kila kila ma ka moʻo 300.ʻO ka hoʻohana maʻamau no ka 321 stainless steel ʻo ia ka annealing, nā ʻōnaehana hoʻopau kaʻa kaumaha, nā pā ahi, nā laina hoʻopaʻa, nā ʻāpana mokulele, a me nā lako lawelawe wela kiʻekiʻe.
