Nui-diameter LSAW tukanga hanga putorino maitai te nuinga faataa:
1. pereti rangahau: whakamahia ki te hanga i te diameter nui submerged arc paiherea paipa maitai hononga putorino tika i muri i tomo i te raina production, te tuatahi-poari whakamātautau ultrasonic tuatahi;

2. Miihini: Miihini mira i roto i te taha e rua-taha o te pereti mira, kia rite ki te whakatutuki i nga whakaritenga o te whanui pereti, nga taha pereti whakarara ki te ahua o te riu me te tohu;

3. Tuhinga o mua: te whakamahi i te miihini i mua i te piko o te miihini i mua i te piko o te pereti mata, me tutuki te taha o te pereti ki nga whakaritenga o te curvature;

4. Te hanga: i te haurua tuatahi o te miihini whakakikorua JCO i muri i te takahanga i mua i te whakapiko i muri i te maha o nga tira kua tohua, ka pehia ki te ahua "J", katahi ka piko te haurua o te pereti maitai, ka pehia ki te ahua "C". , te hanga i te whakatuwheratanga whakamutunga Ko te ahua "O".

5. Tuhinga o mua: hanga he paipa maitai paiherea tuitui tika i muri i te hanga me te whakamahi i te tui hau (MAG) mo te whakapiri tonu;

6. He paihere ki roto: he hononga pewa kua rukuhia te waea-maha (tae atu ki te wha waea) i runga i te paipa rino whiri tika o roto;

7. He paihere ki waho: he hononga pewa kua rukuhia te waea-maha i runga i te LSAW paipa maitai o waho;

8. Ultrasonic whakamātautau: roto me waho o te tui tika paiherea paipa maitai paipa paipa me te weld taha e rua o te rauemi turanga 100% tirotiro;

9. Te tirotiro hihi X: 100% weld i roto, i waho hoki o te tirotiro pouaka whakaata ahumahi X-ray ma te whakamahi i te punaha tukatuka whakaahua hei whakarite i te maaramatanga o te kitenga;

10. Whakawhanaketanga: Mo te whakahiato pewa kua rukuhia me te kohao paipa maitai tuitui te roa te diameter o te kohao kia pai ake ai te tika o te rahi o te ngongo maitai, me te whakapai ake i te tohatoha o te ahotea i roto i te ngongo maitai;

11. Te whakamatautau Hydraulic: I runga i te miihini whakamatautau miihini mo te maitai i muri i te whakawhānui ake i te whakamatautau-a-pakiaka ki te whakarite ko te paipa maitai ki te whakamatautau i nga whakaritenga pehanga o te paerewa, kei te miihini te tuhi aunoa me te kaha rokiroki;

12. Chamfering: te tirotiro paipa maitai whakahaeretia i muri i te mutunga o te tukatuka ki te paipa mutunga beveling whakaritenga rahi.
