Ko te waea parahi, he waea whakarewa i tukatukahia mai i te parahi hiko tino parakore, he pai rawa te kawe hiko, te kawe wera, me te ātete ki te waikura, ā, he whānuitia te whakamahinga i roto i ngā mara maha pēnei i te hiko, te hikohiko, te whakawhitiwhiti kōrero, me ngā rauemi whakarewa. He whero-papura tōna tae, he nui te parahi, he iti noa ngā poke, ā, he nui rawa te kawe hiko, ā, koia te rauemi pai mō ngā waea, ngā taura, me ngā koiri. Ko te nuinga o ā mātou waea kāinga, te pūtake hiko taputapu, me te tuku iahiko teihana utu e whakawhirinaki ana ki te waea parahi. He haumaru, he ātete ki te wera, ā, kāore e ngāwari te waikura, e whakarite ana i te tuku iahiko pumau me te whakaiti i te whakaputanga me te ngaronga wera. Koia te take me whakamahi ngā waea hiko whai tohu i te parahi parakore, kaua i ētahi atu konganuku hei whakakapi.
Ko te waea parahi te nuinga o te wā e whakarōpūtia ana ki ngā kāwai e whai ake nei i runga i tōna hanganga me tōna mahi:
Parahi T2: Ko te mea e whakamahia whānuitia ana, he nui te parahi i roto i te ≥99.90%, he kawe hiko tae atu ki te 100% IACS, he iti te utu, ā, ko te rauemi pai mō ngā pae pahi, ngā takai, me ngā kawe hiko nui.
Parahi TU1/TU2 (Parahi Kore-Hauora): He tino iti te nui o te hāora, kāore e neke atu i te 0.003% te nui o te hāora o te TU2, ā, tae atu ki te 100%-101% IACS te kawe hiko. He ātete ki te pakarukaru hauwai, he pai te mahi miihini, ā, he pai hoki mō ngā taiao korehau me ngā āhuatanga pāmahana teitei.
Parahi TP1/TP2 (parahi whakakore waikura o te ūkuikui): Te kawe hiko tata ki te 97%-99% IACS, he pai mō te whakarewa, ā, he ātete ki te pakaru o te hauwai, he pai mō ngā paipa me ngā whakawhiti wera.
Ko te kaha kume o te waea parahi he 205-315 N/mm² te tikanga, ā, ko tōna pakeke Vickers he 50-120 HV.
He pūnaha whakatakotoranga whai rawa te waea parahi, ka taea te wehewehe mā te diameter, te horahanga whakawhiti-wāhanga rānei, mā te diameter waea rānei ki ngā taumata rerekē.
Ko te whānui o te waea kotahi te whakatakotoranga taketake o te waea parahi. I runga i te whakamahinga, ko ngā whānui o te waea kotahi e whakamahia whānuitia ana ko te 0.05mm, 0.07mm, 0.10mm, 0.12mm, me te 0.15mm. Hei tāpiri, ko ngā whānui o te waea 0.3mm, 0.6mm, 0.8mm, 1mm, 1.5mm, me te 2mm e kitea whānuitia ana i roto i ngā tono ahumahi maha hei whakatutuki i ngā hiahia o ngā āhuatanga rerekē. Mō te tukatuka, ka taea hoki te kume i te waea parahi hei waea parahi tino angiangi, tae atu ki te 0.016 mm.
Mō te waea/rīpene whiri parahi, ko ngā diameter waea kotahi paerewa ko te 0.10 mm, 0.12 mm, me te 0.15 mm, me ngā horahanga whakawhiti mai i te 0.2 mm² ki te 300 mm². Kei roto i ngā whakatakotoranga noa ngā horahanga whakawhiti pēnei i te 2 mm², 4 mm², 6 mm², 8 mm², 10 mm², 16 mm², 25 mm², 35 mm², 50 mm², 100 mm², me te 120 mm², ka taea te whakamahi i roto i ngā hua rīpene/waea whiri parahi.
Hei tāpiritanga, ka taea hoki te whatu me te tukatuka i te waea parahi hei hanga i ngā momo hua pēnei i te whatu waea parahi, ngā hononga waea ngāwari aho parahi, me ngā rīpene whiri parahi whakakikoruatia ki te tine. He maha ngā momo whatu e whakamahia ana e te whatu waea parahi pēnei i te 30 mata, te 60 mata, me te 80 mata.
He tokomaha te hunga e whakaaro ana he "waea kotahi" noa iho te waea parahi, engari he tino uaua te tukanga hanga. Mai i ngā poro parahi ki ngā waea angiangi, he maha ngā mahi o te tukanga tae atu ki te whakamahana, te hurihuri, te kukume, me te whakamahana. Ko te angiangi o te waea parahi, ko te teitei ake o ngā whakaritenga mō te tukatuka me te parakore. Ko ētahi waea parahi tino angiangi e whakamahia ana i roto i ngā taputapu hiko teitei me tukatuka anō i raro i ngā taputapu tino tika kia pakari ai, kia mau ai te kawe hiko.
Mō ētahi atu pārongo e pā ana ki ngā waea parahi, tēnā whakapā mai ki a mātou.
