ASTM A210 Tau C (ASME SA210 Tau C) he ngongo maitai kore-piri waro-waenga i hangaia mō te whakamahi i roto i te hanga ngongo poiha me ngā paipa poiha, tae atu ki ngā pito haumaru, ngā ngongo pakitara oumu me ngā ngongo tautoko, me ngā ngongo whakamahana nui.
He pai ngā āhuatanga ā-pūkaha o te Wāhanga C, me te kaha kume o te 485 MPa me te kaha hua o te 275 MPa. Mā ēnei āhuatanga, me te hanganga matū e tika ana, ka pai ai ngā ngongo Wāhanga C ASTM A210 mō te whakamahi i roto i ngā taiao pāmahana teitei me te pēhanga teitei, ā, ka taea hoki te tu atu i ngā pēhanga e puta mai ana i te whakahaere o te poiha.
Me hanga ngā ngongo mā te tukanga tuimotu, ā, me whakaoti wera, me whakaoti matao rānei.
Kei raro nei he tūtohi rere o te tukanga hanga mō te paipa maitai tui kua oti te whakamatao:
Nā, he aha te rerekētanga i waenga i te paipa maitai kore-whakaoti wera me te paipa maitai matao, ā, me pēhea te whiriwhiri?
Kua oti te weraKo te paipa maitai kore-whakairo he paipa maitai e hurihia ana, e werohia ana rānei i te pāmahana teitei me ētahi atu tukanga, kātahi ka whakamatao tika ki te pāmahana rūma. Ko ngā paipa maitai i tēnei āhua he pai ake te pakari me te kaha, engari kāore pea te kounga o te mata e rite ki ngā paipa maitai kua oti te whakamatao nā te mea ka arahi pea te tukanga maimoatanga wera ki te waikura, ki te tango waro rānei o te mata o te paipa maitai.
Kua oti te whakamataoKo te paipa maitai kore-whakairo e pā ana ki te tukatuka whakamutunga o te paipa maitai mā te kukume makariri, te hurihuri makariri, me ētahi atu tukanga i te pāmahana rūma. He nui ake te tika o ngā āhuatanga o te paipa maitai kua oti te whakamatao, ā, he pai te kounga o te mata, ā, nā te mea ka taea e te tukatuka makariri te whakapai ake i te kaha me te pakeke o te paipa maitai, he pai ake ngā āhuatanga miihini o te paipa maitai kua oti te whakamatao i ērā o te paipa maitai kua oti te whakamahana. Heoi, tera pea ka puta he ahotea toenga i roto i te paipa maitai i te wā e mahi makariri ana, me whakakore atu tēnei mā te maimoatanga wera i muri mai.
Kāore e hiahiatia he maimoatanga wera mō te paipa maitai kua oti te whakamahana.
Me whakamahanahia ngā ngongo kua oti te whakamatao ki raro i te wera, me whakamahana katoa, me whakamahanahia rānei ki te wera noa i muri i te tukanga whakaotinga matao whakamutunga.

Whakamātautau Whakapapatahi
Kāore e kiia he pakaru, he pakaru rānei i ngā tūranga 12, 6 rānei o ngā ngongo Paetae C, he 60.3 mm te whānui o waho, ā, he iti iho rānei, hei pūtake mō te whakakorenga.
Ka taea te tiro i ngā whakaritenga motuhake i roto iASTM A450, tūemi 19.
Whakamātautau Mura
Ka kitea ngā whakaritenga motuhake i roto i te ASTM A450, tūemi 21.
Te pakeketanga
Tau C: 89 HRBW (Rockwell) 179 HBW rānei (Brinell).
Me whakamātau ia paipa rino ki te pēhanga wai-tūturu, ki te whakamātautau hiko kore-whakangaro rānei.
Ko ngā whakaritenga whakamātautau e pā ana ki te pēhanga waipū e hangai ana ki te ASTM 450, tūemi 24.
Ko ngā whakaritenga whakamātautau e pā ana ki te hiko kore-whakangaro e rite ana ki te ASTM 450, tūemi 26.
He mea tika kia hangaia ngā ngongo poiha kia tutuki ai ngā hiahia motuhake o te pūnaha poiha.
Ina whakaurua ki roto i te pōro, me tū ngā ngongo me te whakawhanui me te whakapiko, me te kore e kitea he kapiti, he hapa rānei. Ina tika te whakahaere, me tū ngā ngongo whakamahana nui i ngā mahi hanga, whakarewa, me te piko e tika ana mō te tono, me te kore e puta he hapa.
He kaihanga me te kaiwhakarato paipa maitai waro kounga teitei a Botop Steel nō Haina, he toa paipa maitai kore hononga hoki, e whakarato ana i ngā paipa maitai kounga teitei, paerewa, me te utu whakataetae.
