1. Ukutholwa kwepuleti: ngemva kokuba ipuleti lensimbi elisetshenziselwa ukwakha i-arc enobubanzi obukhulu engaphansi kwamanzi eshiselwe ipayipi lensimbi lomthungo eliqondile lingena emgqeni wokukhiqiza, okokuqala lihlole ukuhlolwa kwepuleti eligcwele;
2. Ukugaya i-Edge: amaphethelo amabili epuleti lensimbi agaywa nhlangothi zombili ngomshini wokugaya onqenqemeni ukuze kuzuzwe ububanzi bepuleti elidingekayo, ukufana konqenqema lwepuleti kanye nokuma kwe-groove;
3. Ukugoba ngaphambili: sebenzisa umshini wokugoba ngaphambili ukuze ugobe ngaphambili unqenqema lwepuleti, ukuze unqenqema lwepuleti lube nokugoba okudingekayo;
4. Ukwakha: emshinini wokwenza i-JCO, qala ngokucindezela uhhafu wepuleti lensimbi eligobe ngaphambili libe umumo othi "J" ngokugxiviza izinyathelo eziningi, bese ugoba enye ingxenye yepuleti lensimbi libe umumo othi "C", bese ekugcineni wenze vula umumo othi "O".
5. I-Welding yangaphambili: yenza ipayipi lensimbi elenziwe ngothungo eliqondile bese usebenzisa i-gas shielded welding (MAG) ukushisela okuqhubekayo;
6. Ukushisela kwangaphakathi: i-longitudinal multi wire submerged arc welding (kufika ezintanjeni ezine) isetshenziselwa ukushisela ngaphakathi kwepayipi lensimbi lomthungo oqondile;
7. Ukushisela kwangaphandle: i-longitudinal multi wire submerged arc welding isetshenziselwa ukushisela ingaphandle lepayipi lensimbi elishiselwe i-arc longitudinal elingaphansi kwamanzi;
8. Ukuhlolwa kwe-Ultrasonic I: I-100% yama-welds angaphakathi nangaphandle wepayipi lensimbi ehlanganisiwe eqondile kanye nesisekelo sensimbi ezinhlangothini zombili ze-weld;
9. Ukuhlolwa kwe-X-ray I: Ukuhlolwa kwe-X-ray yezimboni ze-X-ray kuzokwenziwa kumashisela angaphakathi nangaphandle, futhi uhlelo lokucubungula izithombe luzokwamukelwa ukuze kuqinisekiswe ukuzwela kokutholwa kwamaphutha;
10. Ukunwetshwa kobubanzi: nweba ubude obugcwele bepayipi lensimbi elingaphansi elishiselwe i-arc eqondile ukuze kuthuthukiswe ukunemba kobukhulu bepayipi lensimbi futhi kuthuthukiswe ukusatshalaliswa kokucindezeleka kwangaphakathi epayipini lensimbi;
11. Ukuhlolwa kwe-Hydrostatic: hlola amapayipi ensimbi anwetshiwe ngayinye ngayinye emshinini wokuhlola we-hydrostatic ukuze uqinisekise ukuthi amapayipi ensimbi ahlangabezana nokucindezela kokuhlola okudingekayo ngokwezinga.Umshini unomsebenzi wokuqopha okuzenzakalelayo nokugcinwa;
12. I-Chamfering: sebenzisa ukuphela kwepayipi lepayipi lensimbi elifanelekile ukuze lihlangabezane nosayizi odingekayo we-groove ekupheleni kwepayipi;
13. Ukuhlolwa kwe-Ultrasonic II: ukwenza ukuhlolwa kwe-ultrasonic ngamunye ngamunye futhi ukuze uhlole ukukhubazeka okungenzeka kwamapayipi ensimbi ashiselwe longitudinal ngemva kokunwetshwa kobubanzi nokucindezela kwamanzi;
14. Ukuhlolwa kwe-X-ray II: Ukuhlolwa kwe-X-ray yezimboni zikamabonakude kanye ne-pipe end weld photography kuyokwenziwa kumapayipi ensimbi ngemva kokunwetshwa kobubanzi kanye nokuhlolwa kwe-hydrostatic;
15. Ukuhlolwa kwezinhlayiyana zikazibuthe kokuphela kwepayipi: yenza lokhu kuhlola ukuze kutholwe iziphambeko ekupheleni kwamapayipi;
16. Ukuvimbela ukugqwala kanye nokumboza: ipayipi lensimbi elifanelekayo lizobhekana nokuvimbela ukugqwala kanye nokumbozwa ngokuvumelana nezidingo zomsebenzisi.
