1. Kuonekwa kweplate: mushure mokunge ndiro yesimbi inoshandiswa kugadzira yakakura-diameter yakadzika pasi arc welded yakatwasuka seam simbi pombi inopinda mumutsara wekugadzira, kutanga kuitisa ndiro yakazara ultrasonic inspection;
2. Edge milling: mipendero miviri yendiro yesimbi inogayiwa mativi ese nemuchina wekugaya kuti uwane hupamhi hweplate inodiwa, plate edge parallelism uye groove chimiro;
3. Pre bending: shandisa pre bending machine pre bend the plate edge, kuitira kuti mupendero weplate une curvature inodiwa;
4. Kugadzira: pamuchina wekugadzira JCO, tanga wadzvanya hafu ye pre bent simbi ndiro kuita "J" chimiro kuburikidza neakawanda nhanho kutsika, wozokotamisa imwe hafu yesimbi ndiro kuita "C" chimiro, uye pakupedzisira gadzira vhura "O" chimiro
5. Pre welding: gadzira iyo yakaumbwa yakatwasuka musono yakashongedzwa nesimbi pombi yakabatana uye shandisa gasi shielded welding (MAG) kuti irambe ichiita welding;
6. Internal welding: longitudinal multi waya pasi pemvura arc welding (kusvika kune ina waya) inoshandiswa kupinza mukati yakatwasuka musono simbi pombi;
7. External welding: longitudinal multi wire undermerged arc welding inoshandiswa kupinza kunze kwe longitudinal submerged arc welded steel pipe;
8. Ultrasonic inspection I: 100% yemukati nekunze welds yepipe yakatwasuka yesimbi yesimbi uye nheyo yesimbi kumativi ose maviri e weld;
9. X-ray kuongorora I: 100% X-ray indasitiri yekuongorora terevhizheni ichaitwa mukati nekunze welds, uye mufananidzo wekugadzirisa hurongwa huchagamuchirwa kuti huve nechokwadi chekunzwa kwekukanganisa kwekuona;
10. Kuwedzera kwedhayamita: kuwedzera hurefu hwakazara hwearc yakanyungudutswa yakashongedzwa yakatwasuka seam simbi pombi kuti uvandudze dimensional kurongeka kwepombi yesimbi uye kuvandudza kugoverwa kwemukati kushushikana mupombi yesimbi;
11. Hydrostatic test: ongorora mapaipi esimbi akawedzerwa imwe neimwe pamushini we hydrostatic test kuti uone kuti mapaipi esimbi anosangana nedzvinyiriro yekuyedza inodiwa nechiyero.Muchina wacho une basa rekurekodha otomatiki uye kuchengetedza;
12. Chamfering: gadzira pombi yekupedzisira yepipe yesimbi inokwanisa kusangana nehukuru hunodiwa hwepombi yekupedzisira;
13. Ultrasonic inspection II: ita ultrasonic inspection imwe neimwe zvakare kutarisa kukanganisa kunobvira kwe longitudinal welded steel pipes mushure mekuwedzera kwedhayamita uye kudzvinyirirwa kwemvura;
14. X-ray kuongorora II: X-ray maindasitiri terevhizheni kuongorora uye pombi kupera weld mapikicha achaitwa nokuda simbi pombi pashure dhayamita kuwedzera uye hydrostatic bvunzo;
15. Magnetic particle inspection yepombi kupera: ita iyi ongororo kuti uwane hurema hwepombi kupera;
