ASTM A213 T12(ASME SA213 T12) he paipu kila humuhumu haʻahaʻa i hoʻolālā ʻia no ka lawelawe wela kiʻekiʻe.
ʻO kāna mau mea hoʻohuihui mua he 0.80–1.25% chromium a me 0.44–0.65% molybdenum, nāna i hoʻokaʻawale iā ia ma ke ʻano he kila alloy chromium-molybdenum. Hoʻohana nui ʻia ia i nā wahi wela kiʻekiʻe a me ke kaomi kiʻekiʻe e like me nā paila, nā superheaters, a me nā mea hoʻololi wela.
ʻO ka ikaika tensile liʻiliʻi loa o ka paipu T12 he 415 MPa a me ka ikaika yield liʻiliʻi loa he 220 MPa.
ʻO ka inoa UNS no kēia māka ʻo K11562.
He mea kūʻai aku a kūʻai nui ʻo Botop Steel i nā paipu kila kila kila a ʻoihana hoʻi ma Kina, hiki ke hoʻolako koke i kāu mau papahana me nā ʻano paipu kila kila like ʻole, me nāT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), a meT91 (K90901).
He kūlana hilinaʻi ko kā mākou huahana, he kumukūʻai hoʻokūkū, a kākoʻo i ka nānā ʻana mai 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
Pono nā paipu kila ASTM A213 T12 e hana ʻia ma ke kaʻina hana humuhumu ʻole a pono e hoʻopau wela ʻia a hoʻopau anu ʻia paha, e like me ka mea i kuhikuhi ʻia.
Ka Lapaʻau Wela
Pono e hana ʻia nā paipu kila T12 a pau i ka wela.
ʻO nā ʻano hana mālama wela i ʻae ʻia e komo pū me fka hoʻoheheʻe ʻana a i ʻole isothermal, ka hoʻomaʻamaʻa ʻana a me ka hoʻoikaika ʻana, a i ʻoleka hoʻoheheʻe ʻana ma lalo o ka pilikia.

Pono e hoʻomaopopo ʻia he pono ke hana ʻia ka mālama wela ma ke kaʻawale a me ka hoʻopili ʻana me ka hoʻomehana ʻana.

Ua ʻae ʻia ke kauoha ʻana iā T12 me ka nui o ka sulfur he 0.045. Pono e komo pū ka māka me ka leka "S" ma hope o ka hoʻolālā papa, e like me T12S.

Hoʻohana ʻia i loko o nā mea kanu mana no nā ʻōmole superheater a me nā ʻōmole reheater e hana ana ma lalo o nā mahana a me nā kaomi kiʻekiʻe.
Hoʻohana nui ʻia e like me nā ʻōmole paila i loko o nā kikowaena mana wela, nā ʻāpana hoʻōla wela ʻōpala, a me nā paila ʻoihana.
3. Nā Mea Hoʻololi Wela
Kūpono no nā paipu hoʻololi wela i loko o nā ʻoihana petrochemical a me nā kemika ma muli o kona kūpaʻa maikaʻi i ka kolo ʻana a me ke kūpaʻa wela.
4. Nā ʻŌmole Umu a me nā ʻŌmole Mea Hoʻomehana
Hoʻokomo ʻia i loko o nā ʻōwili umu hoʻomaʻemaʻe, nā paipu hoʻomehana, a me nā mea hoʻomehana hana kahi e pono ai ke kūpaʻa oxidation a me ka ikaika lōʻihi.
