API 5L kazhinji inoreva mutsara pombi-API 5L mutsetse pombi, mutsetse pombi ndeyekutakura oiri, chiutsi uye mvura inobviswa kubva pasi kuenda kumabhizimusi eindasitiri yemafuta negesi kuburikidza nepombi yemutsetse.Mutsara mutopota unosanganisira musono pombi uye welded simbi pombi.Migumo yacho ine magumo akati sandara, magumo ane shinda uye zvigadziko;nzira dzekubatanidza ndeye welding, coupling yekubatanidza, socket yekubatanidza, nezvimwe.

1. Iyo huru yekugadzira nzira yekupisa-yakakungurutswa seamless simbi pombi (main inspection process):
Tube kugadzirira uye kuongorora → chubhu isina kupisa kupisa → kubaya → chubhu kutenderedza → simbi kudzoreredza → yakagadzika (yakadzikiswa) dhayamita → kurapa kupisa △ → yapedza kutwasanura chubhu → kupedza → kuongorora (isingaparadze, yemuviri uye makemikari, Taiwan kuongorora) → imba yekuchengetera
2. Iyo huru yekugadzira nzira yekutonhora-yakakungurutswa (yakadhonzwa) isina musono pombi dzesimbi:
Kugadzirira billet → kunhonga lubrication → kunotonhora kukungurutsa (kudhirowa) → kurapwa kupisa → kururamisa → kupedza → kuongorora
