SA213 kiʻekiʻe-press boiler paipumoʻo he akiʻekiʻe-press boiler paipumoʻo. He kūpono no nā paipu kila ferritic a me austenitic me ka mānoanoa liʻiliʻi o ka paia no nā paila a me nā mea hoʻomehana a me nā paipu kila austenitic no nā mea hoʻololi wela.

ʻO nā paipu wela wela i hoʻohana ʻia i nā paila haʻahaʻa haʻahaʻa a me waena (ʻoi aku ka nui o ka hana ma mua o 5.88Mpa, ʻoi aku ka mahana o ka hana ma lalo o 450 ℃); hoʻohana ʻia i loko o nā paila puʻupuʻu kiʻekiʻe (ʻoi aku ka nui o ke kaomi hana ma luna o 9.8Mpa, ʻo ka mahana hana ma waena o 450 ℃ ~ 650 ℃) ) nā paipu wela wela, superheaters, reheaters, petrochemical industry tubes, etc.

ASME SA213 T12ʻO ka paipu kila kila, ke alakaʻi i nā paipu kila maʻamau maʻamau o ʻAmelika, hoʻohana nui ʻia i ka ʻaila, ʻoihana kemika, mana uila a me nā ʻoihana ʻoihana ʻē aʻe. Hana ʻia kēia ʻano paipu kila i ke kila kila kiʻekiʻe. Ma hope o ka hoʻomaʻamaʻa pono ʻana i nā kaʻina hana he nui, he ikaika kiʻekiʻe a me ke kūpaʻa corrosion kiʻekiʻe. Hiki iā ia ke hoʻokō i nā koi o ka hoʻohana ʻana i nā ʻano paʻakikī like ʻole.

He paʻakikī a nani hoʻi kāna kaʻina hana, me ka hoʻoheheʻe ʻana, ka ʻōwili ʻana, ka hou ʻana, ke kiʻi anuanu, ka mālama wela a me nā loulou ʻē aʻe. I ka wā o ke kaʻina hana, hoʻomaʻamaʻa ka paipu kila i nā hemahema he nui a me ka hoʻāʻo ʻole ʻana e hōʻoia i kona ʻano maikaʻi a me ka hilinaʻi. Aia kekahi ʻano loiloi kemika, loiloi metallographic a me nā hoʻāʻo ʻē aʻe e hōʻoia i ka hoʻohui ʻana, ka hoʻonohonoho hoʻonohonoho, ka hana a me nā hōʻailona ʻē aʻe e hoʻokō i nā koi maʻamau.

ʻO nā hiʻohiʻona oASME SA213 T12ʻO nā paipu kila kila penei:
1. Ka ikaika kiʻekiʻe: He kiʻekiʻe ka ikaika tensile a me ka helu hua, a hiki ke pale i nā ukana nui a me nā hopena.
2. ʻO ke kūpaʻa kiʻekiʻe o ka corrosion: Loaʻa iā ia ke kūpaʻa corrosion ikaika ma nā ʻano paʻakikī like ʻole, e like me nā waikawa, nā alkalis, nā paʻakai a me nā mea kemika ʻē aʻe a me nā kaiapuni koʻikoʻi e like me ke kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.
3. Hana maikaʻi i ka hana kuʻi: Hanaʻia me ke kila kiʻekiʻe,ʻaʻole hiki ke maʻa i nā māwae, nā pores a me nā pilikia'ē aʻe i ka wā o ka wiliʻana, e hōʻoiaʻiʻo ana i ka maikaʻi a me ka hilinaʻi.
4. Ka nui o nā noi: Hoʻohana nui ia i ka petroleum, ka ʻoihana kemika, ka mana uila a me nā ʻoihana ʻē aʻe, e like me ka aila a me ka pipeline gas, boilers, reactors a me nā mea hana ʻē aʻe.
