He mea tino pai te whakarewa pewa ruku mō ngā paipa, ngā oko pēhanga me ngā tāke, te hanga rēriwe me ngā tono hanga nui, me te āhua monofilament māmā rawa, te hanganga waea takirua, te hanganga waea takirua takirua me te hanganga maha-filament.
He maha ngā painga o te whakarewatanga pewa i raro i te wai mō ngā kaiwhakamahi. Mai i te whakapiki i te hua, ki te whakapai ake i te taiao mahi, ki te whakarite i te kounga pumau, me te maha atu. Ko ngā kaihanga tukatuka whakarewa e whakaaro ana ki ngā huringa i roto i te tukanga whakarewatanga pewa i raro i te wai, me whakaaro rātou he maha ngā painga ka taea e rātou te whiwhi mai i tēnei tukanga.
Te mōhiotanga taketake mō te whakarewa pewa i raro i te wai
He whakaritenga te tukanga whakarewa pewa i raro i te wai mō ngā mahi ahumahi taumaha pērā i ngā paipa, ngā oko pēhanga me ngā tāke, te hanga waka tereina, te hanga taumaha/kerihanga. He pai mō ngā ahumahi e hiahia ana ki te whakaputa hua nui, inā koa ka tae ki te whakarewa i ngā rauemi matotoru rawa, he maha ngā painga ka riro mai i te tukanga whakarewa pewa i raro i te wai.
Ka pā nui te tere whakatakotoranga me te tere hikoi ki te hua o ngā kaimahi, te whai huatanga me ngā utu whakaputa, koinei tētahi o ngā painga matua o te tukanga whakarewa pewa ruku.
Ko ētahi atu painga ko: he pai rawa te hanganga matū me ngā āhuatanga hangarau o te whakarewa, he iti te kitea o te pewa me te iti o ngā paowa whakarewa, he pai ake te whakamarie o te taiao mahi, ā, he pai te āhua me te rārangi matimati o te whakarewa.
Ko te whakarewa pewa ruku he tikanga whāngai waea e whakamahi ana i te rerenga kirikiri hei wehe i te pewa mai i te hau, e ai ki te ingoa, ka tanumia te pewa ki roto i te rerenga, ko te tikanga ina whakatakotoria ngā tawhā, kāore e kitea te pewa me te putanga mai o tētahi paparanga rerenga. Ka whāngaihia tonutia te waea whakarewa e tētahi rama e neke ana i te taha o te whakarewa.
Mā te whakamahana āwhata ka whakarewahia tētahi wāhanga o te waea, tētahi wāhanga o te rerenga me te konganuku turanga, ka hanga he puna rewa, ka whakapūmau hei hanga i tētahi whakarewa kua hipokina ki tētahi paparanga o te para whakarewa. Ko te whānuitanga matotoru o te rauemi whakarewa he 1/16"-3/4", ka taea te whakarewa kotahi te urunga 100% mā te whakarewa kotahi, ki te kore e whakawhāitihia te matotoru o te pakitara, ka taea te whakarewa maha-haere, ā, ka tika te tukatuka me te whiriwhiri i te whakarewa, ā, ka whiriwhiria te huinga rerenga waea whakarewa e tika ana.

Te kōwhiringa o te waea rere me te waea whakarewa
He mea nui te whiriwhiri i te rerenga me te waea tika mō tētahi tukanga whakarewa pewa ruku hei whakatutuki i ngā hua pai rawa atu mā te whakamahi i te tukanga. Ahakoa he pai te whai hua o ngā tukanga whakarewa pewa ruku anake, ka taea te whakapiki ake i te hua me te whai huatanga ahakoa i runga i te waea whakarewa me te rerenga e whakamahia ana.
Ehara i te mea ka tiaki noa te rerenga i te puna whakarewa, engari ka whai wāhi hoki ki te whakapai ake i ngā āhuatanga miihini me te hua o te whakarewa. He nui te pānga o te hanganga o ngā rerenga ki ēnei āhuatanga, e pā ana ki te kaha kawe iahiko me te tukunga para.
Ko te kaha kawe o nāianei te tikanga ka taea te whiwhi i te tino pai o te whakatakotoranga me te kounga teitei o te kōtaha whakarewa.
Ka pā te tukunga para mai i tētahi rerenga ki te kōwhiringa rerenga nā te mea he pai ake ētahi rerenga mō ētahi hoahoa tūhono i ētahi atu.
Ko ngā kōwhiringa whiriwhiri rerenga mō te whakapiringa pewa ruku ko ngā momo whakarewa hohe me ngā momo whakarewa kūpapa. Ko tētahi rerekētanga matua ko te rerenga hohe ka whakarerekē i te matū o te whakarewa, engari kāore te rerenga kūpapa.
Ko ngā rerenga hohe e tohuhia ana e te whakaurunga o te silicon me te manganese. Ka āwhina ēnei huānga ki te pupuri i te kaha kume o te whakarewa i te whakaurunga wera nui, ka āwhina ki te pupuri i te whakarewa kia maeneene me te maeneene i ngā tere haere teitei, ā, ka whakarato i te tukunga para pai. I te nuinga, ka taea e ngā rerenga hohe te āwhina ki te whakaiti i te mōrearea o te kounga whakarewa ngoikore, me te horoi me te mahi anō utu nui i muri i te whakarewa. Heoi, kia maumahara ko ngā rerenga hohe te mea tino pai mō te whakarewa kotahi, takirua rānei.
He pai ake ngā rerenga kūpapa mō ngā whakarewa maha-haerenga nui, nā te mea ka āwhina i te karo i te hanganga o ngā whakarewa pakarukaru, tairongo-ngatata.
He maha ngā momo waea whakarewa e wātea ana mō te whakarewa pewa ruku, he pai, he ngoikoretanga hoki ia momo. Ko ētahi waea he mea hanga mō te whakarewa i ngā whakaurunga wera teitei ake, ko ētahi he mea hanga motuhake kia whai koranu hei āwhina i te rere ki te mahi horoi whakarewa.
Kia mōhio koe, ko ngā āhuatanga matū me te taunekeneke wera o te waea whakarewa ka pā ki ngā āhuatanga ā-pūkaha o te whakarewa. Ka taea hoki te whakanui ake i te hua mā te whiriwhiri i te konganuku whakakī.
Hei tauira, mā te whakamahi i te waea matua whakarewa me te tukanga whakarewa pewa i raro i te wai ka taea te whakanui ake i te whai huatanga o te whakatakotoranga mā te 15% ki te 30% ki te whakaritea ki te whakamahi i te waea totoka, me te whakarato hoki i te kōtaha urunga whānui ake, pāpaku ake hoki.
Nā te tere haere tere, ka whakaitihia hoki e ngā waea matua whakarewa te wera e uru mai ana kia iti ake ai te mōrearea o te whakarerekētanga o te āhua me te wera o te whakarewa.
O ngā maitai katoa, ko ngā maitai kore waikura austenitic te mea iti rawa te pūnga hua. Nō reira, i runga i ngā āhuatanga ā-pūkaha, ehara te maitai kore waikura austenitic i te rauemi pai rawa atu mō te kakau takirere, nā te mea hei whakarite i tētahi kaha, ka piki ake te whānui o te kakau takirere. Kāore e taea te whakanui ake i te pūnga hua mā te maimoatanga wera, engari ka taea te whakanui ake mā te hanga matao.
He toa mātou o ngā paipa maitai kore waikura me te waro, nau mai haere mai ki ngā pātai katoa, ka tukuna atu e mātou i te wā tuatahi!
