ASTM A213 T12(ASME SA213 T12) he paipa maitai kore-honohono iti-konumohe i hangaia mō te mahi pāmahana teitei.
Ko ōna huānga whakarewa matua ko te 0.80–1.25% chromium me te 0.44–0.65% molybdenum, e whakarōpūtia ana hei maitai whakarewa chromium-molybdenum. He whānuitia te whakamahinga i roto i ngā taiao pāmahana teitei me te pēhanga teitei pērā i ngā kohua, ngā whakamahana nui, me ngā whakawhiti wera.
Ko te kaha kume iti rawa o te paipa T12 he 415 MPa, ā, ko te kaha tuku iti rawa he 220 MPa.
Ko te tohu UNS mō tēnei tohu ko K11562.
He kaihokohoko paipa rino koranu ngaio, pono hoki a Botop Steel, ā, ka taea e ia te tuku tere i ō kaupapa ki ngā momo paipa rino koranu, tae atu kiT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), meT91 (K90901).
He pono te kounga o ā mātou hua, he utu whakataetae, ā, e tautoko ana i ngā tirotiro a te hunga tuatoru.

Kaihanga me te Āhua
Me hanga ngā paipa maitai ASTM A213 T12 mā te tukanga tuimotu, ā, me whakaoti wera, me whakaoti matao rānei, e ai ki te whakaritenga.
Te Maimoatanga Wera
Me whakamahana ngā paipa rino T12 katoa.
Ko ngā tikanga maimoatanga wera e whakaaetia ana ko te fte whakamahanatanga o te werawera, te whakamahana rānei, te whakataurite me te whakamāmā, rāneiwhakamahanatanga i raro i te arohaehae.

| Whakamātautau Mura | Me mahi tētahi whakamātautau mura ki ngā tauira mai i ia pito o te ngongo kua oti te hanga, kaua ki te mea e whakamahia ana mō te whakamātautau papatahi, mai i ia puranga. | |
Me whakamātau ia ngongo ki te hiko kore-whakangaro, ki te whakamātautau wai-pūmau rānei.Ko te momo whakamātautau hei whakamahi me whiriwhiri e te kaihanga, ki te kore e tohua tētahi atu mea i roto i te ota hoko.
Me whakahaere ngā tikanga whakamātautau i runga anō i ngā whakaritenga e tika ana o ngā Wāhanga 25 me te 26 o ASTM A1016.
Ko ngā rahi o ngā ngongo ASTM A213 T12 me ngā matotoru o te pakitara he mea whakarite kia puta mai i te 3.2 mm ki te 127 mm ngā diameter o roto, ā, ko te matotoru iti rawa o te pakitara mai i te 0.4 mm ki te 12.7 mm.
Ka taea hoki te tuku atu i ētahi atu rahi o ngā paipa maitai T12, ki te tutukihia ngā whakaritenga katoa o te ASTM A213.
Ko ngā ngongo maitai ASTM A213 T12 he mea whakamahi nui i roto i ngā taiao ratonga pāmahana teitei me te pēhanga teitei. Ko ngā tono noa ko:
1. Ngā Whakamahana Nui me ngā Whakamahana Anō
Whakamahia ana i roto i ngā tipu hiko mō ngā ngongo whakamahana nui me ngā ngongo whakamahana anō e mahi ana i raro i ngā pāmahana me ngā pēhanga teitei.
E whakamahia whānuitia ana hei ngongo poiha i roto i ngā teihana hiko wera, ngā waeine whakaora wera para, me ngā poiha ahumahi.
3. Ngā Whakawhiti Wera
He pai mō ngā ngongo whakawhiti wera i roto i ngā ahumahi hinu me te matū nā te mea he pai tōna ātete ki te ngokingoki me te pumau ki te wera.
4. Ngā Ngongo Ouma me ngā Ngongo Whakamahana
Ka tāuta ki roto i ngā koiri oumu whakarewa, ngā ngongo whakamahana, me ngā whakamahana tukatuka e hiahiatia ana te ātete ki te waikura me te kaha mō te wā roa.
5. Ngā Paipa Pēhanga i roto i ngā Whare Hiko me ngā Whare Matū
Whakamahia ana mō ngā paipa pāmahana teitei, tae atu ki ngā paipa mamaoa me ngā paipa kawe wai wera.
