As haurua-ā-iraā, i te whanaketanga o ngā hangarau hiko iti ki te taumata mahi teitei ake me te whakaurunga teitei ake, ka nui ake ngā whakaritenga e pā ana ki te parakore o ngā hau hiko motuhake. He wāhanga nui o te pūnaha tuku hau parakore te hangarau paipa hau parakore. Koinei te hangarau matua mō te tuku hau parakore e tutuki ana i ngā whakaritenga ki ngā wāhi whakamahi hau me te pupuri tonu i te kounga tika.
Kei roto i te hangarau paipa parakore-teitei te hoahoa tika o te pūnaha, te kōwhiringa o ngā hononga paipa me ngā rauemi āwhina, te hanganga me te tāutanga me te whakamātautau.
01 Te ariā whānui o ngā paipa tuku hau
Me kawe ngā hau parakore me ngā hau ma ki te pūwāhi hau whakamutunga mā roto i ngā paipa. Hei whakatutuki i ngā whakaritenga kounga tukanga mō te hau, ina tino mōhiotia te taupū kaweake hau, he mea nui ake te aro ki te kōwhiringa rauemi me te kounga hanga o te pūnaha paipa. Haunga te tika o ngā taputapu whakaputa hau, taputapu purenga rānei, he maha ngā āhuatanga o te pūnaha paipa e pāngia nuitia ana. Nō reira, me whai te kōwhiringa o ngā paipa i ngā mātāpono o te umanga purenga e tika ana, me te tohu i te rauemi o ngā paipa i roto i ngā tuhi.
02Te hiranga o ngā paipa parakore-teitei i roto i te kawe hau
Te hiranga o ngā paipa parakore-teitei i roto i te kawe hau parakore-teitei I te wā o te tukanga whakarewa maitai kore waikura, ka taea e ia tana te mimiti i te 200 karamu o te hau. I muri i te tukatuka o te maitai kore waikura, ehara i te mea ko ngā poke anake ka piri ki tōna mata, engari ka mimitihia hoki he nui o te hau ki roto i tōna whatunga whakarewa. Ina rere te hau i roto i te paipa, ka hoki anō te wāhanga o te hau e mimitihia ana e te whakarewa ki roto i te rere o te hau, ka whakapokea te hau parakore.
Ina mutu te rere o te hau i roto i te paipa, ka hangaia e te paipa he mimiti pēhanga ki runga i te hau e haere ana. Ina mutu te rere o te hau, ka hangaia he tātaritanga whakaiti pēhanga e te hau e mimitihia ana e te paipa, ā, ka uru atu te hau kua tātarihia ki te hau parakore i roto i te paipa hei paru.
I taua wā anō, mā te huringa mimiti me te tātari ka puta he paura i te konganuku i te mata o roto o te paipa. Ka whakapokea hoki e tēnei matūriki puehu konganuku te hau parakore i roto i te paipa. He mea tino nui tēnei āhuatanga o te paipa. Hei whakarite i te parakore o te hau e haria ana, ehara i te mea me tino maeneene te mata o roto o te paipa, engari me tino ātete hoki ki te kakahu.
Mēnā he kaha te waikura o te hau, me whakamahi ngā paipa maitai kore waikura hei hanga i ngā paipa. Ki te kore, ka puta he ira waikura ki te mata o roto o te paipa nā te waikura. I ngā wā tino kino, ka tihorea ngā konganuku nunui, ka pokaia rānei, ā, ka poke te hau parakore e haria ana.
Rauemi paipa 03
Me whiriwhiri te rauemi o te paipa kia rite ki ngā hiahia o te whakamahinga. Ko te kounga o te paipa ka inehia i runga i te taratara o te mata o roto o te paipa. Mēnā he iti te taratara, he iti ake te tūponotanga ka mauria e ia ngā matūriki. E toru ngā momo:
Ko tētahiPaipa EP 316L, kua whakakanapahia mā te hikohiko (Hiko-Whakakanapa). He ātete ki te waikura, ā, he iti te taratara o te mata. Ko te Rmax (te teitei mōrahi mai i te tihi ki te awaawa) he tata ki te 0.3μm, iti iho rānei. Ko tōna papatahi te mea tino teitei, ā, he uaua ki te hanga i ngā iahiko moroiti-pōro. Tangohia ngā matūriki poke. Me tuku paipa te hau tauhohenga e whakamahia ana i roto i te tukanga ki tēnei taumata.
Ko tētahi heTaumata BA 316Lhe paipa, kua tukatukahia e Bright Anneal, ā, e whakamahia ana mō ngā hau e pā ana ki te maramara engari kāore e whai wāhi ki te tauhohenga tukanga, pērā i te GN2 me te CDA. Ko tētahi ko te paipa AP (Annealing & Picking), kāore i te rongoatia motuhake, ā, e whakamahia whānuitia ana mō ngā huinga takirua o ngā paipa o waho kāore e whakamahia hei raina tuku hau.
04 Te hanga paipa
Ko te tukatuka i te waha o te paipa tētahi o ngā kaupapa matua o tēnei hangarau hanga. Ka mahia te tapahi me te hanga i mua i te paipa i roto i te taiao ma, ā, i te wā kotahi, ka whakarite kia kore he tohu kino, he pakaru rānei i runga i te mata o te paipa i mua i te tapahi. Me whakarite kia horoia te hauota ki roto i te paipa i mua i te whakatuwheratanga o te paipa. Ko te tikanga, ka whakamahia te whakarewa hei hono i ngā paipa tuku me te tohatoha hau tino ma, tino ma hoki, he nui te rere, engari kāore e whakaaetia te whakarewa tika. Me whakamahi ngā hononga anga, ā, me kore e rerekē te hanganga o te rauemi paipa i whakamahia i te wā e whakarewahia ana. Mena ka whakarewahia te rauemi he nui rawa te waro, ka puta te hau i roto, i waho hoki o te paipa nā te uruhanga o te hau ki roto, ki waho hoki, ka pakaru te parakore, te maroke me te ma o te hau kawe, ka hua ake he hua kino, ka pā ki te kounga whakaputa.
Hei whakarāpopototanga, mō ngā paipa tuku hau parakore teitei me ngā paipa tuku hau motuhake, me whakamahi he paipa maitai kore waikura parakore teitei kua rongoatia motuhake, kia whai wāhi nui ai te pūnaha paipa parakore teitei (tae atu ki ngā paipa, ngā hononga paipa, ngā takirere, VMB, VMP) ki te tohatoha hau parakore teitei.
