ASTM A210 Papa C (ASME SA210 Papa C) he paipu kila maʻemaʻe ʻole kalapona i hoʻolālā ʻia no ka hana ʻana i nā paipu paila a me nā ʻauheʻe paila, me nā hopena palekana, ka paia o ka umu ahi a me nā paipu kākoʻo, a me nā paipu superheater.
Loaʻa i ka Papa C nā waiwai mechanical maikaʻi, me ka ikaika tensile o 485 MPa a me ka ikaika hua o 275 MPa. ʻO kēia mau waiwai, me kahi hui kemika kūpono, hana i nā paipu ASTM A210 Grade C i kūpono no ka hoʻohana ʻana i ka wela kiʻekiʻe a me ke kiʻekiʻe. nā kaiapuni kaomi a hiki ke kū i nā kaomi i hana ʻia e ka hana boiler.
E hana ʻia nā paipu ma ke kaʻina hana ʻole a hoʻopau ʻia i ka wela a i ʻole ke anu.
Aia ma lalo iho kahi papa kuhikuhi o ke kaʻina hana no ka paipu kila liʻiliʻi i hoʻopau ʻia.
No laila he aha ka ʻokoʻa ma waena o ka paipu kila ʻole i hoʻopau wela a me ke anuanu a pehea ʻoe e koho ai?
Hoʻopau welaʻO ka paipu kila maʻemaʻe he paipu kila i'ōwiliʻia a houʻia paha i kahi wela kiʻekiʻe a me nā kaʻina hana'ē aʻe a laila hoʻomaha pololei i ka mahana wela.ʻO nā paipu kila ma kēia mokuʻāina ʻoi aku ka maikaʻi o ka paʻakikī a me ka ikaika, akā ʻaʻole maikaʻi ka maikaʻi o ka ʻili e like me nā paipu kila i hoʻopau ʻia no ka mea hiki i ke kaʻina hana wela ke alakaʻi i ka oxidation a i ʻole decarburization o ka ʻili o ka paipu kila.
Hoʻopau anuʻO ka paipu kila maʻemaʻe e pili ana i ka hana hope loa o ka paipu kila ma ke kaha kiʻi anuanu, ka ʻōwili anu, a me nā kaʻina hana ʻē aʻe ma ka lumi wela.ʻO ka paipu kila i hoʻopau ʻia i ke anuanu, ʻoi aku ka kiʻekiʻe o ka pono, a me ka maikaʻi o ka ʻili, a no ka mea hiki ke hoʻomaikaʻi i ka hana anu i ka ikaika a me ka paʻakikī o ka paipu kila, ʻoi aku ka maikaʻi o nā waiwai mechanical o ka paipu kila i hoʻopau ʻia ma mua o ka paipu kila wela. .Eia nō naʻe, hiki ke hana ʻia kekahi nui o ke koena o ke koʻikoʻi i loko o ka paipu kila i ka wā hana anuanu, pono e hoʻopau ʻia e ka mālama wela ma hope.
ʻAʻole pono ka paipu kila i hoʻopau ʻia i ka wela.
ʻO nā paipu i hoʻopau ʻia i ke anu e hoʻopili ʻia, hoʻopili piha ʻia, a i ʻole ka wela maʻamau e mālama ʻia ma hope o ke kaʻina hana hoʻopau anu.

Ke hoʻokomo ʻia i loko o ka paila, e kū mau nā paipu me ka hoʻonui ʻana a me ka wili ʻole me ka ʻike ʻole ʻia o nā māwae a me nā hemahema.Ke hoʻohana pono ʻia, e kū nā paipu superheater i ka forging a pau.wiliwili.a me nā hana kulou e pono ai no ka noi me ka hoʻomohala ʻole ʻana i nā hemahema.
ʻO Botop Steel kahi mea hana kiʻekiʻe kiʻekiʻe welded carbon steel paipu a me ka mea hoʻolako mai Kina, a me kahi mea hoʻopaʻa paipu kila maʻemaʻe, hāʻawi iā ʻoe i ka paipu kila kiʻekiʻe, maʻamau, a me ka hoʻokūkū.
Inā pono ʻoe, e ʻoluʻolu e kelepona mai iā mākou, nā loea, ma ka pūnaewele no kāu lawelawe!
