ASTM A213 T12(ASME SA213 T12) he paipu kila liʻiliʻi liʻiliʻi i hoʻolālā ʻia no ka lawelawe wela kiʻekiʻe.
ʻO kāna mau mea hoʻohui mua he 0.80-1.25% chromium a me 0.44-0.65% molybdenum, e hoʻokaʻawale iā ia ma ke kila kila chromium-molybdenum. Hoʻohana nui ʻia ia i nā wahi wela kiʻekiʻe a me ke kiʻekiʻe e like me nā boilers, superheaters, a me nā mea hoʻololi wela.
Loaʻa i ka paipu T12 ka ikaika tensile haʻahaʻa o 415 MPa a me ka ikaika haʻahaʻa haʻahaʻa o 220 MPa.
ʻO ka inoa UNS no kēia papa ʻo K11562.
ʻO Botop Steel kahi mea kūʻai paipu kila kila a hilinaʻi hoʻi ma Kina, hiki iā ia ke hoʻolako koke i kāu mau papahana me nā pae like ʻole o nā paipu kila kila, e komo pū ana.T5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), aT91 (K90901).
ʻO kā mākou huahana o ka maikaʻi kūpono, kūʻai hoʻokūkū, a kākoʻo i ka nānā ʻana i nā ʻaoʻao ʻekolu.
No nā kauoha a i ʻole ka ʻike hou aku, e ʻoluʻolu e kelepona mai iā mākou i kēia lā!
Mea Hana a me ke Kūlana
ʻO nā paipu kila ASTM A213 T12 e hana ʻia e ke kaʻina hana ʻole a hoʻopau wela a i ʻole ke anu, e like me ka mea i ʻōlelo ʻia.
Hoʻomaʻamaʻa Wela
Pono nā paipu kila T12 a pau e mālama i ka wela.
ʻO nā ʻano hana lapaʻau ʻae ʻia he full a isothermal annealing, hana maʻamau a me ka hoʻoulu ʻana, a i ʻolesubcritical annealing.

Pono e hoʻomaopopo ʻia e pono e hoʻokaʻawale ʻia ka mālama wela a me ka hoʻohui ʻana i ka hana wela.

Ua ʻae ʻia ke kauoha iā T12 me ka nui o ka sulfur content o 0.045. E hoʻokomo ʻia ka māka "S" ma hope o ke koho papa, e like me T12S.

| Hoʻāʻo ʻana i ke ahi | E hana ʻia hoʻokahi hoʻāʻo ʻana ma luna o nā mea hoʻohālike mai kēlā me kēia kihi o hoʻokahi paipu i hoʻopau ʻia, ʻaʻole ka mea i hoʻohana ʻia no ka hoʻāʻo palahalaha, mai kēlā me kēia ʻāpana. | |
E kau ʻia kēlā me kēia paipu i ka hoʻāʻo uila nondestructive a i ʻole ka hoʻāʻo hydrostatic.ʻO ke ʻano o ka hoʻāʻo e hoʻohana ʻia ma ke koho o ka mea hana, ke ʻole i kuhikuhi ʻia ma ke kauoha kūʻai.
E hoʻokō ʻia nā ʻano hoʻāʻo e like me nā koi pili o nā Pauku 25 a me 26 o ASTM A1016.
Hoʻolako pinepine ʻia ka nui o nā paipu ASTM A213 T12 a me nā mānoanoa pā me nā anawaena o loko mai ka 3.2 mm a i waho o nā anawaena o 127 mm, a me nā mānoanoa pā liʻiliʻi mai 0.4 mm a i 12.7 mm.
Hiki ke hoʻolako ʻia nā ʻano nui ʻē aʻe o nā paipu kila T12, inā e hoʻokō ʻia nā koi āpau o ASTM A213.
ʻO ka ASTM A213 T12 alloy steel seamless tubes i hoʻohana mua ʻia i nā ʻoihana lawelawe kiʻekiʻe a me ke kaomi kiʻekiʻe. Loaʻa nā noi maʻamau
1. Nā mea hoʻomehana a me nā mea hoʻomaha
Hoʻohana ʻia i nā mea kanu mana no ka superheater a me ka reheater tubes e hana ana ma lalo o nā wela kiʻekiʻe a me nā kaomi.
Hoʻohana nui ʻia e like me nā paipu boiler i nā kikowaena mana wela, nā ʻāpana hoʻolaʻa wela-wela, a me nā boilers ʻoihana.
3. Na mea hoololi wela
He kūpono no ka paipu hoʻololi wela i ka ʻoihana petrochemical a me kemika ma muli o kona kūpaʻa maikaʻi ʻana a me ke kūpaʻa wela.
4. Puhi ahi a me na paipu wela
Hoʻokomo ʻia i loko o nā coils umu hoʻoheheʻe ʻia, nā paipu wela, a me nā mea hoʻomehana kaʻina kahi e koi ʻia ai ke kūpaʻa oxidation a me ka ikaika lōʻihi.
5. Paipu Paipu Paʻi i loko o nā Mea Mana Mana a me Petrochemical
Hoʻohana ʻia no nā paipu wela wela, me nā laina mahu a me nā laina lawe wai wela.
