Ko te ERW he paipa whakarewa ātete-auau teitei; ko te LSAW he paipa whakarewa pewa ruku-aukati; nō ngā paipa whakarewa hononga-tika e rua ēnei, engari he rerekē te tukanga whakarewa me te whakamahinga o ngā mea e rua, nō reira kāore e taea te tohu i ngā paipa whakarewa hononga-tika anake. He maha ake ngā mea e whakamahia ana ko ngā paipa whakarewa SSAW-porowhita-porowhita.

Te rerekētanga me te whakamahinga o ngā paipa maitai ERW, LSAW me SSAW

Ko te hononga tika auau teitei (paipa maitai ERW) ka wehea ki te whakarewatanga whakapūmau me te whakarewatanga whakapā i runga i ngā tikanga whakarewatanga rerekē. Ka whakamahia he koiri whānui kua hurihia wera hei rauemi mata. Whai muri i te piko-mua, te hanga tonu, te whakarewatanga, te maimoatanga wera, te whakapiri, te whakatikatika, te tapahi, he painga o ngā whakarewatanga poto, te tika o ngā āhuatanga, te matotoru o te pakitara, te kounga pai o te mata me te pēhanga teitei ki te whakataurite ki te porowhita. Heoi, ko te ngoikoretanga ko ngā paipa angiangi anake me ngā diameter iti me te reo ka taea te whakaputa. He koha waikura honohono, he rite ki te awaawa. Ko ngā wāhi e whakamahia whānuitia ana i nāianei ko te kawe hua hau maori me te hinu mata o te tāone.

Ko te whakarewa pewa ruku hāngai (paipa maitai LSAW) ka hangaia mā te whakamahi i tētahi pereti matotoru kotahi hei rauemi mata, te pēhi (te hurihuri) i te pereti maitai ki roto i tētahi pokepoke, mīhini hanga rānei, te whakarewa pewa ruku taha-rua, me te whakawhanui i te whānui. He whānui ngā whakatakotoranga o te hua kua oti, he pakari pai te whakarewa, he kirihou, he ōrite me te mātotoru, ā, he painga o te whānui paipa nui, te pakitara paipa matotoru, te ātete ki te pēhanga teitei, te ātete ki te pāmahana teitei me te ātete ki te waikura. I te hanga i ngā paipa hinu me te hau tawhiti-kaha, teitei-kaha, kounga teitei, ko ngā paipa maitai e hiahiatia ana he pewa ruku hāngai he whānui-rahi te whānui, he pakitara matotoru. E ai ki te paerewa API, i roto i ngā paipa hinu me te hau nui, i te wā e haere ana i roto i ngā rohe Akomanga 1 me te Akomanga 2 (pērā i ngā rohe maunga, ngā takere moana, me ngā rohe tāone nui), ko te pewa ruku hāngai anake te momo paipa kua tohua. E ai ki ngā tikanga hanga rerekē, ka taea te wehewehe ki: U0E/JCOE/HME.

Ko te tikanga o te whakarewa porowhita-uru (paipa maitai SSAW) i te wā e hurihia ana te paipa, ko tōna ahunga whakamua kei te koki (ka taea te whakarite) ki te rārangi pokapū o te paipa hanga, ā, ka mahia te whakarewa i te wā e hanga ana, ā, ka hangaia e tōna whakarewa he rārangi porowhita. Ko te painga ko te whakatakotoranga kotahi ka taea te whakaputa paipa maitai o ngā diameter rerekē, he whānui te whānuitanga o ngā rauemi mata, ka taea e te whakarewa te karo i te ahotea matua, ā, he pai te ahotea. Ko te ngoikoretanga ko te iti o te rahi āhuahanga. He roa ake te roa o te whakarewa i te tuitui tika. Ka puta ngā kapiti, ngā pūwero, ngā whakaurunga para me ngā pekapeka whakarewa. Mō ngā hapa whakarewa, kei roto te ahotea whakarewa i te āhua ahotea kume.

E ai ki ngā whakaritenga hoahoa mō ngā paipa whānui mō te hinu me te hau tawhiti, ko te pewa ruku porowhita ka taea anake te whakamahi i roto i ngā rohe Akomanga 3 me te Akomanga 4. Whai muri i te whakapai ake i te tukanga ki tāwāhi, ka whakakapia ngā rauemi mata ki ngā pereti maitai hei wehewehe i te hanga me te whakarewa. Whai muri i te whakarewanga-mua me te tika, ka whānui te diameter whakarewa i muri i te whakarewanga makariri. He tata te kounga whakarewa ki te paipa UOE.
I tēnei wā, kāore he tikanga pēnei i Haina. Koinei te huarahi whakapai ake mō tā mātou wheketere. Kei te hangaia tonutia te paipa "Tuku Hau Hauāuru-Rawhiti" i runga i te tukanga tuku iho, engari kua whakawhānuihia te whānui o te pito o te paipa.
Ko te nuinga o te wā, ko te Hononga o Amerika, ko Hapani me Tiamana e whakakahore ana ki te whakamahi i te SSAW, ā, e whakapono ana hoki rātou kāore e tika ana kia whakamahia te SSAW e te ara matua.
E whakamahia ana e Kānata me Itari te SSAW i ētahi wāhanga, ā, he iti noa iho ngā rahinga o te SSAW e whakamahia ana e Rūhia. He tino tino pakari ngā whakaritenga tāpiri kua whakaritea e rātou. Nā ngā take hītori, kei te whakamahi tonu te nuinga o ngā raina pūngao ā-rohe i te SSAW. Ka hurihia te rauemi mata ki te pereti maitai hei wehe i te hanga me te whakarewa. Whai muri i te whakarewa-mua me te tika, ka whakawhanuitia te diameter whakarewa i muri i te whakarewa makariri. He tata te kounga whakarewa ki te paipa UOE.
Ko te paipa whakarewa hononga tika ERW e whakamahia whānuitia ana hei anga waea i roto i te umanga hiko. Ngā āhuatanga mahi: Mā te whakamātautau ultrasonic 100% o te rauemi matua ka whakarite i te kounga ā-roto o te tinana paipa; kāore he tukanga kutikuti kōpae wetewete, ā, he iti ake ngā poka me ngā karawarawa o te rauemi matua; ko te paipa kua oti i muri i te whakakorenga o te ahotea kāore he ahotea toenga; he poto te whakarewa, ā, he iti te tūponotanga o ngā hapa; ka taea te kawe i te hau maori kawa makuku; i muri i te whakawhānui i te diameter, he teitei te tika o te rahi āhuahanga o te paipa maitai; ka mahia te whakarewa i roto i te rārangi tika i roto i te tūranga whakapae i muri i te otinga o te hanganga, kia pai ai te whakahaere i te he o te whakatakotoranga, te whakatuwheratanga o te tuitui, me te porowhita o te diameter o te paipa, ā, he tino pai te kounga whakarewa. Ngā paerewa hua ka taea te whakahaere: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 14291-2006 me ētahi atu paerewa hou. Ko ngā momo maitai o te hua ko: GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, me ētahi atu. He whānuitia te whakamahinga o ēnei hua ki te hinu, ki te hau māori, ki te hau waro, ki ngā maina waro, ki ngā mīhini, ki te hiko, ki te whakatō pou me ētahi atu kaupapa. Ngā taputapu hangarau tukatuka matatau: pērā i te whakahāngai W-FF, te whakarewatanga auau-teitei totoka, te kimi hapa ultrasonic, te kimi hapa turuturu aukume, me ngā taputapu whakamātautau matatau: pērā i te tātari whakarewa, te whakamātautau pakeke Vickers, te mīhini whakamātautau pānga, te tātari whānuitanga, te mīhini whakamātautau whānui me ētahi atu taputapu. Ka kaweakehia ngā hua ki Amerika ki te Tonga, ki Amerika ki te Raki, ki te Kotahitanga o Ūropi, ki Āhia ki te Tonga-mā-rāwhiti me ētahi atu wāhi. I roto i ngā tau, kua pai te manakohia e ngā kiritaki puta noa i te ao.
