Mō te hanga paipa rino o ēnei rā, ko te ERW (Electric Resistance Welding) me te HFW (High-Frequency Welding) ngā tikanga whakaputa e rua e tino kitea ana, e tino whai hua ana hoki. Ahakoa he rite tonu te āhua i te tuatahi, he rerekē ngā tikanga whakarewa, ngā paearu kounga, me ngā whānuitanga tono o ngā paipa rino ERW me HFW. He mea nui te mārama ki te rerekētanga i waenga i ngā paipa rino ERW me HFW hei whiriwhiri i te rauemi e tika ana mō tō kaupapa.
He aha te meaPaipa ERW?
ERW (Whakarewa Ātete Hiko)Ka hangaia ngā paipa mā te hurihuri i tētahi koiri maitai kia rite ki te āhua porotaka, tapawhā rānei, kātahi ka honoa ngā taha mā te whakamahi i te iahiko hiko me te pēhanga ā-pūkaha.
Mā te wera e puta mai i te ātete hiko i te hononga ka rewa, ka hanumi hoki ngā taha maitai, ka hanga he hononga totoka, tonu.
E mōhiotia ana ngā paipa ERW mō:
Te tino tika o ngā āhuatanga
Te matotoru o te pakitara rite tonu
Te whai huatanga o te utu mō te whakaputanga nui
E whakamahia whānuitia ana ēnei paipa i roto i ngā pūnaha tuku wai, ngā paipa pēhanga iti, me ngā tono hanganga whānui.
He aha te meaPaipa HFW?
HFW (Whakarewa Auau-Teitei)Ko te paipa he momo paipa ERW e whakamahi ana i te iahiko auau-teitei (neke atu i te 100 kHz) hei whakamahana me te whakarewa i ngā taha maitai.
He rerekē ki te ERW tuku iho, e whakawhirinaki ana ki te iahiko auau-iti, ka whakamahia e te HFW he wera arotahi, kaha-nui ki tētahi wāhi iti, kia iti ake ai te rohe e pāngia ana e te wera (HAZ) me te pai ake o te hanganga whakarewa.
Kei roto i te tukanga:
1. Te hanga i te rīpene maitai ki te āhua e hiahiatia ana (porowhita, tapawhā, tapawhā hāngai rānei).
2. Te whakamahana i ngā taha mā te whakamahi i te iahiko auau-tiketike.
3. Whakapiripirihia ngā taha kua wera ki te pēhanga hei hanga i tētahi hononga maeneene, kore hononga.
Mā te hangarau HFW ka taea ngā whakarewanga ma, tika ake, me te iti o te waikura, ā, he pai mō ngā ngongo maitai hanganga kaha-teitei me ngā paipa tapawhā tino tika.
Ngā Rerekētanga Matua i waenga i ngā Paipa ERW me ngā Paipa HFW
Whakamārama Hangarau
Ahakoa e whakawhirinaki ana te ERW me te HFW ki te ātete hiko hei whakaputa wera, he nui te pānga o te iahiko me te auau motuhake ki te tukanga.
Te Mātāpono Whakarewa ERW:
Ka rere te iahiko auau-iti mā roto i te rīpene maitai, ka hanga he wera i te hononga mā te ātete. Kātahi ka akiakihia ngā taha wera kia honoa kia hanga he hononga pakari.
Te Mātāpono Whakarewa HFW:
Ka whakamahia te whakapūngao auau-teitei hei hanga i te wera kaha, kukū tika i te rārangi whakarewa. Ka puta he whakarewa pai ake, he oro ake, me te iti rawa o te whakapōturitanga o ngā rauemi.
Ko te HFW he whanaketanga matatau ake o te ERW, i hangaia hei whakapai ake i te kounga o te whakarewa, te tere whakaputa, me te whai huatanga o te mahi whānui.
Ngā Whakamahinga o ngā Paipa ERW me HFW
E whakamahia ana ngā paipa ERW me HFW i roto i te whānuitanga o ngā ahumahi, engari he rerekē ngā whakamahinga i runga i ngā hiahia mahi.
Ngā Paipa Rino ERW:
Ngā paipa wai me te hau
Te tūāpapa me te taiapa
Ngā pūnaha kawe waka iti-pēhanga
Ngā hanganga hangarau whānui
Ngā Paipa Rino HFW:
Hanganga rino me ngā anga whare
Ngā wāhanga poraka tapawhā me te tapawhā hāngai
Te hanga waka me te mīhini
Ngā whare kati kōtuhi, ngā taonga whare, me te hanganga tika
I te mea ka taea e ngā paipa HFW te whakatutuki i te kaha whakarewa teitei me te tika o ngā āhuatanga, he maha ngā wā e pai ake ana ēnei i roto i ngā mahi hanga hou me ngā mahi miihini.
Ngā Kōwhiringa Maimoatanga Mata
E wātea ana ngā paipa ERW me HFW i roto i ngā momo whakaotinga mata rerekē:
Mangu (kāore i rongoatia):He mata pōuri tūturu, e whakamahia ana mō ngā taiao o roto, mō ngā taiao kore-waikura rānei.
Pirau wera-tō:Ka whakarei ake te paninga konutea i te ātete ki te waikura, he mea tino pai mō ngā pūnaha o waho, mō ngā pūnaha rānei e pāngia ana e te wai.
Kua pania ki te paura, kua pania rānei:Whakamahia hei ātaahua, hei tiaki atu rānei i te waikura.
Tianjin Yuantai Derun Rōpū,e whakarato ana i ngā paipa tapawhā HFW mangu me ngā ngongo maitai piauau hei whakatutuki i ngā whakaritenga tono kanorau.
Mō ngā kaupapa e hiahia ana ki ngā ngongo hanganga kaha-teitei, ki ngā ngongo tapawhā tino tika rānei, mā te whiriwhiri i ngā ngongo HFW kua whakarewaina ka roa ake te ora mahi me te pai ake o te mahi i ngā ngongo ERW tuku iho.
