ʻO nā paipu paila kila ASTM A213: T11, T22 a me ke alakaʻi ʻana i nā mea hana paipu paila mahana kiʻekiʻe

ʻO nā papa kila hao i hoʻohana pinepine ʻia i loko o ke kūlana ASTM A213 e komo pū ana me kekahi mau kila hao chromium-molybdenum e hāʻawi ana i ke kūpaʻa i ka deformation wela kiʻekiʻe. Hoʻohana nui ʻia kēia mau mea i nā paila hale hana mana no ka mea hoʻomaikaʻi ka chromium i ke kūpaʻa oxidation ʻoiai hoʻonui ka molybdenum i ka ikaika kolo.

Aia ma lalo iho kahi ʻike holoʻokoʻa o kekahi mau papa kila huila ASTM A213 i hoʻohana pinepine ʻia.

Ma waena o kēia mau mea,ʻO nā paipu kila ASTM A213 T11 a me ASTM A213 T22ʻo ia nā mea i hoʻohana nui ʻia i nā ʻōnaehana paila ʻoihana. Hāʻawi kēia mau papa i ka ikaika maikaʻi loa i nā mahana kiʻekiʻe me ka mālama ʻana i ka weldability maikaʻi a me nā ʻano hana.

Nā paipu kila ASTM A213 T11aia ma kahi o 1.25% chromium a me 0.5% molybdenum. Hāʻawi kēia ʻano hana i ka pale ʻana i ka oxidation wela kiʻekiʻe i hoʻohālikelike ʻia me nā mea kila kalapona e like meASTM A192 a me ASTM A210Hoʻohana nui ʻia nā paipu T11 i lokonā paipu paila, nā paipu superheater, a me nā paipu hoʻololi welama nā hale hana mana.

Nā paipu kila ASTM A213 T22loaʻa nā pae kiʻekiʻe o ka chromium a me ka molybdenum, ma kahi o 2.25% chromium a me 1% molybdenum. Hāʻawi kēia ʻano hana i ka ikaika kolo i hoʻomaikaʻi nui ʻia a me ke kūpaʻa wela lōʻihi. Ma muli o kēia mau waiwai, hoʻohana pinepine ʻia nā paipu T22 i lokonā ʻōnaehana superheater wela kiʻekiʻe a me nā paipu reheateri loko o nā hale hana mana o kēia au.

ʻO nā ʻokoʻa o ka hoʻohuihui kemika ma waena o nā paipu kila T11 a me T22 he kuleana koʻikoʻi i ka hoʻoholo ʻana i kā lākou hana ma lalo o nā kūlana mahana kiʻekiʻe. Hōʻike ka papa ma lalo nei i kahi hoʻohālikelike maʻalahi ma waena o kēia mau mea paipu paila koʻikoʻi ʻelua.

Ma muli o ka hoʻonui ʻia o ka nui o ke kopa,ʻOi aku ka maikaʻi o ka ikaika o ka mahana kiʻekiʻe a me ke kūpaʻa kolo ma mua o nā paipu T11 i nā paipu T22.Eia nō naʻe, hoʻohana nui ʻia nā paipu T11 ma muli o ko lākou hui pū ʻana o ka ikaika, ka hiki ke hoʻopili ʻia, a me ka pono o ke kumukūʻai.

Hoʻomaka ke kaʻina hana ʻana o nā paipu kila ASTM A213 me nā billet kila alloy i koho pono ʻia. Pono kēia mau billet e hoʻokō i nā koi hoʻohuihui kemika paʻa i wehewehe ʻia e ke kūlana ASTM. Ke hōʻoia ʻia ka mea billet, hoʻomehana ʻia a hou ʻia e hana i kahi pūpū paipu hakahaka me ka hoʻohana ʻana i ke kaʻina hana hou wela e like me nā ʻano hana ʻana o nā paipu seamless ʻē aʻe.

Ma hope o ka hana ʻia ʻana o ka ʻōmole hakahaka mua, hiki i ka hana hou ke komo pū me ka ʻōwili wela a i ʻole ke kahakiʻi anu ma muli o nā koi dimensional o ka huahana hope loa.Hoʻohana pinepine ʻia ke kaha kiʻi anu i ka wā e pono ai nā ana kikoʻī kiʻekiʻe, ʻoi aku hoʻi nonā paipu hoʻololi wela a me nā ʻōnaehana paipu pailakahi e pono ai ke ahonui paʻa.

Hoʻokele ʻo Womic Steel i nā laina hana paipu seamless holomua i hiki ke hana i nā paipu kila ASTM A213 i huki anu ʻia. ʻO kēia mau hale hana e komo pū ana me nā mīkini huki anu hou, nā umu mālama wela, nā lako hoʻopololei, a me nā ʻōnaehana nānā ʻole luku. Ma o nā kaʻina hana hana i kāohi ʻia, hōʻoia ʻo Womic Steel i nā waiwai mechanical kūlike a me ka pololei o nā ana no kēlā me kēia paipu paila kila alloy.

He mea nui ka mālama wela i ka hana ʻana o nā paipu kila ASTM A213. Pono nā kila kila e like me T11 a me T22 i ka mālama wela i kāohi pono ʻia e hoʻokō i ka microstructure kūpono a me nā waiwai mechanical. Hoʻohana pinepine ʻia nā kaʻina hana normalizing a me tempering e hoʻomaikaʻi i ka ikaika, ka paʻakikī, a me ke kūʻē ʻana i ka deformation thermal.

Ma waho aʻe o ka kaohi hana ʻana, pono nā kaʻina hana nānā pono no nā paipu paila kila alloy. Ma muli o ka hana ʻana o kēia mau paipu i nā wahi koi nui loa, hiki i nā hemahema i loko o ka mea ke alakaʻi i ka hāʻule ʻana o nā lako.

ʻO nā kaʻina hana nānā maʻamau:

• Hoʻāʻo ultrasonic e ʻike i nā hemahema kūloko
• Ka hoʻāʻo ʻana o ke au Eddy no nā kīnā o ka ʻili
• Ka hoʻāʻo ʻana i ke kaomi hydrostatic e hōʻoia i ke kū'ē ʻana o ke kaomi
• Ka nānā ʻana i ka haku mele kemika a me ka hoʻāʻo ʻana i ka waiwai mechanical

At Womic Steel, ʻo kēlā me kēia pūʻulu o nā paipu paila kila ASTM A213 e nānā pono ʻia ma mua o ka hoʻouna ʻana. Mālama ka ʻoihana i nā lako hoʻāʻo holomua a me nā hui nānā akamai e hōʻoia i ka hoʻokō ʻana me nā kūlana honua e komo pū anaASTM A213, ASTM A210, ASTM A192, a me EN10216 P235GH.

Hoʻohana nui ʻia nā paipu kila ASTM A213 i nā ʻōnaehana paila hale hana mana hou. Ma kēia mau hale, hoʻohana pinepine ʻia nā paipu e like menā paipu superheater, nā paipu reheater, a me nā paipu hoʻoili wela kiʻekiʻeHana kēia mau ʻāpana ma lalo o nā kūlana wela koʻikoʻi kahi e ʻoi aku ai ka mahana ma mua o 500°C a ʻoi aku paha i nā ʻōnaehana hana mana holomua.

Ma muli o ko lākou kūpaʻa maikaʻi loa i ka kolo ʻana a me ka ikaika o ka mahana kiʻekiʻe, nā mea e like meASTM A213 T11 a me ASTM A213 T22he mea nui ia no ka mālama ʻana i ka hilinaʻi lōʻihi o kēia mau ʻōnaehana. ʻO ka hiki o nā paipu kila alloy ke kū i nā pōʻaiapuni koʻikoʻi wela a me ka hoʻolōʻihi ʻana i nā mahana kiʻekiʻe e hōʻoiaʻiʻo ana i ka hana paʻa o nā paila a me nā mea hoʻololi wela i nā makahiki he nui.

Ma waho aʻe o nā hale hana mana, hoʻohana nui ʻia nā paipu kila ASTM A213 i lokonā hale hana hoʻomaʻemaʻe aila, nā hale hana petrochemical, a me nā ʻōnaehana hoʻomehana ʻoihanaPono kēia mau ʻoihana i nā mea paipu hilinaʻi i hiki ke lawelawe i nā wai wela kiʻekiʻe a me nā wahi ʻinoʻino me ka mālama ʻana i ka pono o ke kūkulu ʻana.

Me ka ʻike nui i ka hana ʻana i nā paipu seamless,Hāʻawi ʻo Womic Steel i nā paipu kila kopa ASTM A213 kiʻekiʻe no nā mea kūʻai aku ʻoihana honuaHāʻawi ka ʻoihana i kahi laulā piha o nā mea paipu paila e komo pū ana meNā paipu kila kalapona ASTM A192, nā paipu paila ASTM A210, nā paipu kila huila ASTM A213, a me nā paipu paila humuhumu EN10216 P235GH.

Ma waho aʻe o nā paipu pololei maʻamau, hāʻawi pū ʻo Womic Steelnā lawelawe hana maʻamau no nā paipu hoʻololi wela, meNā paipu kūlou U, nā paipu serpentine, nā paipu kūlou he nui, a me nā ʻaha paipu hoʻokino kūikawāKākoʻo kēia mau hoʻonā i hoʻopilikino ʻia i nā ʻoihana ʻenekinia a me nā mea hana lako i ka hoʻolālā ʻana i nā ʻōnaehana hoʻoili wela kūpono.

I ka hoʻomau ʻana o ka ulu ʻana o ke kahua ikehu ʻoihana, ke ikaika nei ke koi no nā mea paipu wela kiʻekiʻe hilinaʻi. ʻO nā paipu paila kila alloy i hana ʻia e like me ke kikoʻī ASTM A213 e hoʻomau i ka pāʻani koʻikoʻi i ka hana mana hou, ka hana petrochemical, a me nā ʻōnaehana hoʻololi wela ʻoihana.

Ma o ka ʻenehana hana holomua, nā kaʻina hana hoʻomalu maikaʻi, a me ka ʻike nui i ka hana ʻana i nā paipu seamless,Ke hoʻomau nei ʻo Womic Steel i ka hoʻolako ʻana i nā ʻōmole paila kila kila hana kiʻekiʻe no nā papahana ʻoihana honuaʻO nā mea e like me ASTM A213 T11 a me T22 e mau nei nā mea koʻikoʻi i ka hōʻoia ʻana i ka hana palekana a me ka pono o nā ʻōnaehana paila hou.
