Ngā paipa whakarewae toru ngā wāhanga matua i runga i ngā tukanga hanga me ngā tauira whakarewa: ERW (ngā paipa whakarewa ātete), LSAW (ngā paipa whakarewa pewa ruku tuitui-papatahi), me HSAW/SSAW (ngā paipa whakarewa pewa ruku porowhita).

He rerekē ngā arotahi o ia tukanga hanga me ngā horopaki tono. Hei whakarāpopototanga: Ko te ERW te mea matua i hangaia mō ngā diameter iti me te rahi waenga, me te whakanui i te whai huatanga me te tika; LSAWhe tino pai mō ngā diameter nui me ngā tono pēhanga teitei, koia te whiringa pai mō ngā kaupapa mōrearea nui; i te mea ka taea e te HSAW te whakaputa diameter tino nui mā te whakamahi i ngā rauemi whaiti, e tuku ana i te utu tino pai.

Te Whakataurite i ngā Momo Matua e Toru o ngā Paipa Whakarewa Ahumahi

Tuatahi, kua kohikohia e au ō rātou rerekētanga matua ki roto i tētahi ripanga whakarāpopototanga hei tirotiro tere:

Tātaritanga Taipitopito o ngā Momo Paipa Whakarewahia

Ngongo ERW (Whakarewa Ātete Hiko)

Ko te ERW te mea matua e whakamahi ana i te pānga kiri me te pānga tata o te iahiko hiko hei whakamahana i ngā taha o te rīpene maitai kia rewa, ā, ka whai akemā te pēhanga hei whakatutuki i te hanumitanga. Kāore he waea whakarewa e tāpirihia puta noa i te tukanga katoa.

Ngā painga matua me ngā herenga: Ngā paipa ERWhe poto, he maeneene ngā āhuatanga o ngā whakarewahe tino tika ngā tuitui me te tika o ngā āhuatanga me te iti o te utu.Heoi, he tairongo te rauemi ki te hanganga matū, ā, kei reira te mōrearea o ngā hapa hanumi kāore i oti i roto i ngā whakarewa.

Te Hanga me ngā Paerewa: Ka whakamahia e te tukanga ERW tētahi raina whakaputa tere tonu, he mea tino pai mō te hanga papatipu.Ko ngā paerewa matua mō te tutuki i ngā whakaritenga ko te API 5L me te GB/T 9711.1.

Ngā horopaki tono: Koinei te tino kaupapa matua i roto i te mara o ngā paipa iti me te rahi waenga, whānuitiae whakamahia ana i roto i te tuku me te tohatoha hau i roto i ngā tāone, te kawe hinu kua whakapaia, ngā whatunga tuku wai, me te tautoko hanganga mō ngā whare.

LSAW (Whakarewa Āwhata Ruku Roa) paipa whakarewa āwhata ruku honohono tika

I roto i te tukanga LSW, ka pēhia tuatahitia he pereti maitai kotahi kia hanga he āhua porotaka ki runga i te mīhini hanga, ka hangaia he whakatuwheratanga roa. Muri iho, ka whakamahia tika te waea whakarewa whakakī hei mahi whakarewa pewa rua-taha ki runga i ngā mata o roto, o waho hoki o te ngongo parakore.

Ngā Tikanga Hanga: Ko ngā tukanga hanga matua ko te UOE, te JCOE, me te HME. I roto i ēnei, ko te tikanga UOE, e whakauru ana ihe tukanga whakawhanui i te diameter i muri i te whakarewanga, ka whakakorea pai ngā ahotea o roto, ka hua ake he tino tika te hua kua oti.

Painga Matua: Ko te hononga whakarewa te wāhi ngoikore rawa atu o te hanganga paipa. Ngā painga katoa o ngā paipa LSAWi ahu mai i tā rātou tukanga whakarewa tika, ka taea hoki te whakahaere, ā, ka hua ake he kounga whakarewa tino teitei.

Ngā Paerewa me ngā Rauemi: Te piri ki ngā paerewa pēnei i te API 5L me te GB/T 9711, me ngā whakaritenga pakari mō te kounga o ngā rauemi me ngā tukanga whakaputa.

Ngā horopaki tono: Koia te "paipa kua tohua" mō ngā tono mōrearea/uara nui, pērā i ngā raina matua ongā paipa hinu me te hau pehanga teitei tawhiti, ngā paipa raro i te wai, ngā wāhi he tino makariri, he tino rū whenua rānei, me ngā paipa e whiti ana i ngā awa.

Paipa HSAW (Helical Submerged Arc Welding)

Ko te HSAW (e mōhiotia ana ko SSAW) he whāngai tonu i te rīpene maitai ki roto i te mīhini hanga i tētahi koki motuhake, ka meinga kia neke haere porowhita pērā i te puna kōpiko, me ōna taha e hono ana hei hanga i tētahi hononga porowhita. Muri iho, ka whakakāhia pai tēnei hononga e tētahi mīhini whakarewa pewa rua-taha.

Ngā kaha me ngā ngoikoretanga matua: He ngāwari ngā taputapu, engari ko tekua tino whakanuia te roa o te whakarewa porowhita. Mai i te tirohanga tātari ahotea, ko te whakarewaka taea te karo i te ahunga tuatahi o te ahotea ā-roto; heoi, kāore i te tino pai tana mahi i raro i ngā āhuatanga ahotea uaua pēnei i te kawenga rū whenua.

Whakarōpūtanga me ngā Paerewa: I runga i te whakatauranga pēhanga, ka taea te whakarōpū i ēnei ki ngā paipa tuku wai whānui (hei tauira, te paerewa SY/T5037) me ngā paipa tuku wai e mau ana i te pēhanga (hei tauira, te paerewa GB/T 9711).

Ngā horopaki tono: He whānuitia te whakamahinga i roto i ngā kaupapa tuku wai pēhanga iti tawhiti, whānui, paipa whakamahana tāone, me ngā hanganga pikau-pūtake pou mō ngā tauranga me ngā piriti.

Whakarāpopototanga: Me pēhea te whiriwhiri?

Ko te tikanga whānui, ko te whiriwhiri i te paipa whakarewa tika he tauwhitinga i waenga i te mahi, te utu, me te mōrearea.

Ko te mahi te mea nui, ko te utu te mea nui: ko te LSAW te mea nui.

Te arotau i te whai huatanga o te utu: I roto i ngā tono pēhanga teitei tuku iho pērā i te tuku hinu me te hau me ngā whatunga paipa tāone, he kōwhiringa tino pai te ERW.

Te whakatutuki i ngā diameter tino nui mō te ōhanga: Mō ngā kaupapa diameter nui e hiahia ana kia ngāwari te pēhanga me ngā paerewa kounga whakarewa—pērā i te tuku wai me te taraiwa pou—Ko te HSAW te kōwhiringa tino pai.
