E ai ki te tikanga hanga, ka taea te wehewehe i ngā paipa rino kia rua ngā wāhanga: ngā paipa rino kore hononga me ngā paipa rino whakarewa. I roto i ēnei, ko ngā paipa rino ERW te momo matua o ngā paipa rino whakarewa. I tēnei rā, e rua ngā momo paipa rino e whakamahia ana hei rauemi mata mō te anga: ngā paipa anga kore hononga me ngā paipa anga ERW.
Paipa anga tui kore – he paipa anga i hangaia ki te paipa maitai tui kore; Ko te paipa maitai tui kore e pā ana ki te paipa maitai i hangaia mā te whakamahi i ngā tikanga e whā: te hurihuri wera, te hurihuri matao, te kukume wera me te kukume matao. Kāore he hononga i roto i te tinana o te paipa.
Tinana ERW – Ko te paipa rino ERW (Electric Resistant Weld) i hangaia mai i te paipa hiko kua whakarewahia, e pā ana ki te paipa hononga roa i whakarewahia mā te whakarewa ātete auau teitei. Ko ngā pepa rino mata (ngā koiri) mō ngā paipa hiko kua whakarewahia, he mea hanga mai i te rino waro-iti i hurihia e te TMCP (tukanga whakahaere wera).
1. Paipa maitai kore-tuuturu e manawanui ana ki te OD: mā te whakamahi i te tukanga hanga hurihuri wera, ka oti te rahi i te 8000°C pea. He nui te awe o te hanganga o te rauemi mata, ngā āhuatanga whakamatao, me te āhua whakamatao o te roera ki tōna diameter o waho, nō reira he uaua ki te whakahaere tika i te diameter o waho, ā, he nui te whānuitanga o te nekehanga. Paipa maitai ERW: ka hangaia mā te piko makariri, ā, ka whakaitihia tōna diameter mā te 0.6%. He pumau te pāmahana tukanga i te pāmahana rūma, nō reira ka whakahaere tikahia te diameter o waho, ā, he iti te whānuitanga o te nekehanga, he pai ki te whakakore i ngā whitiki hiako pango;
2. Paipa maitai kore-tuitui me te ātete matotoru pakitara: Ka hangaia mā te poka i te maitai porowhita, ā, he nui te rerekētanga matotoru pakitara. Ka taea e te huri wera i muri mai te whakakore i te koretake o te matotoru pakitara, engari ka taea e ngā mīhini hou te whakahaere i roto i te ±5 ~ 10%t anake. Paipa maitai ERW: Ina whakamahia te koiri huri wera hei rauemi mata, ka taea te whakahaere i te ātete matotoru o te huri wera hou i roto i te 0.05mm.
3. Kāore e taea te whakakore i ngā hapa o te mata o waho o te mea mahi e whakamahia ana mō te āhua o te paipa rino kore hononga i roto i te tukanga hurihuri wera, engari ka taea anake te whakakanapa i muri i te otinga o te hua kua oti, ko te whiu porowhita i mahue i muri i te werohanga ka taea anake te whakakore i te wāhanga i roto i te tukanga whakaiti i ngā pakitara. Ko te paipa rino ERW he mea hanga mai i te koiri hurihuri wera hei rauemi mata. Ko te kounga o te mata o te koiri he rite tonu ki te kounga o te mata o te paipa rino ERW. He ngawari te whakahaere i te kounga o te mata o ngā koiri hurihuri wera, ā, he kounga teitei. Nō reira, he pai ake te kounga o te mata o te paipa rino ERW i te paipa rino kore hononga.
4. Paipa maitai porowhita kore hononga: mā te whakamahi i te tukanga hurihuri wera. He nui te pānga o te hanganga rauemi mata o te paipa maitai, ngā āhuatanga whakamatao me te āhua whakamatao o te roera ki tōna diameter o waho, nō reira he uaua ki te whakahaere tika i te diameter o waho, ā, he nui te whānuitanga o ngā nekehanga. Paipa maitai ERW: ka hangaia mā te piko makariri, ka whakahaere tikahia te diameter o waho, ā, he iti te whānuitanga o ngā nekehanga.
5. Whakamātautau kume Ko ngā āhuatanga kume o ngā paipa maitai kore hononga me ngā paipa maitai ERW e rite ana ki ngā paerewa API, engari ko te kaha o te paipa maitai kore hononga kei te rohe o runga, ā, ko te ngāwari kei te rohe o raro. Engari, ko te taupū kaha o te paipa maitai ERW kei te āhua pai rawa atu, ā, ko te taupū kirihou he 33.3% teitei ake i te paerewa. Ko te take he mea hei rauemi mata mō ngā paipa maitai ERW, ka whakamanahia te mahi o te koiri hurihuri wera e te whakarewa koranu moroiti, te whakamahine i waho o te oumu, me te whakamatao me te hurihuri whakahaere; kirihou. He tūponotanga whaitake.
6. Ko te rauemi mata o te paipa maitai ERW he koiri hurihuri wera, he tino tika te tukanga hurihuri, ka taea ai te whakarite i te mahi ōrite o ia wāhanga o te koiri.
7. Ko te rauemi mata o te paipa koiri maitai hurihuri wera ERW me te rahi o te kōhao he whānui, he matotoru hoki te paparanga totoka kōhao pai o te mata, kāore he wāhi o ngā tioata pou, he porosity whakaheke me ngā kōhao, he iti te rerekētanga o te hanganga, ā, he kiato te hanganga; ka taea te whakahaere i te tukanga hurihuri i muri mai. Mā te whakamahi i te hangarau hurihuri matao ka whakarite i te rahi o te kōhao o te rauemi mata.
8. Ko te whakamātautau ātete paheke o te paipa maitai ERW e pā ana ki ngā āhuatanga o te rauemi mata me te tukanga hanga o te paipa. He pai ake te matotoru o te pakitara me te āhua porowhita i ngā paipa maitai kore hononga, koinei te take matua he teitei ake te ātete hinga i ngā paipa maitai kore hononga.
9. Whakamātautau Pānga Nā te mea he maha ngā wā ka teitei ake te pakari o te rauemi turanga o te paipa maitai ERW i tērā o te paipa maitai kore hononga, ko te pakari o te whakarewa te mea nui ki te paipa maitai ERW. Mā te whakahaere i te nui o ngā poke i roto i te rauemi mata, te teitei me te ahunga o te pū tapahi, te āhua o te taha hanga, te koki whakarewa, te tere whakarewa, te kaha me te auau whakamahana, te rahinga whakaputa whakarewa, te pāmahana me te hohonu o te whakahokinga auau waenga, te roa o te wāhanga whakamatao hau me ētahi atu tawhā tukanga ka whakamanahia. Ka eke te pānga o te kaha whakarewa ki te neke atu i te 60% o te konganuku turanga. Mā te arotautanga anō, ka taea e te kaha pānga o te whakarewa te tata ki te kaha o te konganuku turanga, e whakarite ana i te mahi kore raruraru.
10. Whakamātautau pahūtanga He nui ake te mahi whakamātautau pahūtanga o ngā paipa maitai ERW i ngā whakaritenga paerewa, nā te mea he ōrite te matotoru o te pakitara me te diameter o waho o ngā paipa maitai ERW te nuinga.
