Kupu Whakataki
Paipa Kowiri tira kua whakawerahiahe paipa kowiri tira kore-tūhono, he paipa whakarewa rānei kua whakamahanatia ki te pāmahana maimoatanga otinga motuhake, ā, kua whakamataohia i te tere whakahaeretia hei whakaora i te ātete ki te waikura, te ngāwari me te hanganga whakarewa ōrite. Mō ngā taumata austenitic pērā i te 304L me te 316L, ka whakarewahia e te whakamahana otinga ngā warowaiha whai-chromium, ā, ka whakaitihia te tūponotanga o te waikura intergranular e pā ana ki te whakaaweawe. Mō ngā maitai kowiri tira takirua, ka āwhina hoki ki te whakatū i te taurite e hiahiatia ana i waenga i te austenite me te ferrite.
Ka whakamahia ngā paipa whakawerawera ki te tukatuka matū, ki ngā taputapu kai me te inu, ki ngā pūnaha rongoā, ki ngā whakaurunga hinu me te hau, ki ngā whakawhiti wera, ki te maimoatanga wai, ki ngā paipa moana me te ratonga wai parakore. Me whakamārama e ngā kaihoko te tohu, te paerewa hua, te hanganga kore hononga, te hanganga whakarewa rānei, ngā ine, te āhua maimoatanga wera, te mutunga o te mata, ngā whakaritenga whakamātautau waikura me te tiwhikete tirotiro.
Ngā whakatakotoranga matua:
• Me tohu te "Whakamahana" i te tikanga tuku whakamutunga, kaua ko te taahiraa whakaputa waenga noa iho.
• Me ōrite te pāmahana me te tikanga whakamatao o te otinga ki te kounga o te maitai kore waikura.
• He rerekē te āhua o te mata me te ma o ngā paipa whakawerawera pīkara me ngā paipa whakawerawera kanapa.
• Me whakaū e te MTC te tau wera, te tohu, te paerewa, ngā āhuatanga miihini me te āhua i tukuna.
He aha ngā mahi a te whakamahana i te paipa kowiri tira?
Ka whakarerekē te kukume makariri, te hanga, te whakarewa me te mahi wera i te hanganga iti o te paipa kowiri tira. Ka taea e ēnei mahi te whakaputa i te ahotea toenga, te whakapakeketanga mahi, te maturuturunga o te chromium-carbide, te taurite āhua kino rānei. Ka whakamahia te whakamahana otinga hei whakahoki i te rauemi ki tētahi āhua e tika ana mō te mahi ātete-waikura me te hanga i muri mai.
Te whakarewa i ngā kāpirati konupora
Ka taea e ngā maitai kore waikura austenitic te hanga i ngā warowaiha chromium ina whakaatuhia ki ētahi pāmahana waenga mō te wā roa. Ka tangohia te chromium mai i ngā rohe witi e karapoti ana, ka waiho ngā rohe kua pau te chromium. Ka taea e ēnei rohe te ngoikore ki te waikura intergranular i roto i te taiao kaha.
I te wā e tukatukahia ana te otinga, ka whakamahanahia te paipa kia ranea hei whakarewa i ēnei warowaiha ki roto i te hanganga austenitic. Kātahi ka whakawhāitihia te ua hou mā te whakamatao tere. Ko te huringa wera tuturu e whakawhirinaki ana ki te taumata, te matotoru o te wāhanga, te hoahoa oumu me te whakatakotoranga rauemi whakahaere.
Te Whakaora i te Māeneene i Muri i te Mahi Matao
Ka nui ake te kaha me te pakeke o te paipa e tōia ana i te matao mā te whakapakeketanga taumaha, engari ka heke te roa me te āhua o te hanga. Mā te whakamahana ka taea te hanga anō i te tioata, ka whakaiti i te pakeke me te whakahoki mai i te ngāwari. He mea nui tēnei ina pikohia, ina whakawhanuitia, ina mura, ina whakarewahia, ina hangaia rānei te paipa hei huihuinga taputapu.
Te Whakahaere i te Taurite Wāhanga Takirua
Kei roto i ngā maitai kore waikura takirua te ferrite me te austenite. Mā te huringa maimoatanga wera kāore i te tika ka nui rawa te ferrite, ka kino rānei ngā wāhanga intermetallic, ka whakaiti i te pakari me te ātete ki te waikura. Nō reira, ko te whakamahana otinga whakamutunga me te whakamatao tere he taahiraa hanga nui mō ngā paipa takirua me ngā paipa tino takirua.
