Kupisa kupisa (kuendesaSeamless Steel pombi): Round Tube Billet→kupisa→kuboora→matatu-rolly cross kutenderera, kuenderera mberi kuyerera kana kuwedzerwa→kubvarura→Sizing (kana kuderedza)→kutonhora→kururamisa→Hydraulic test (kana kuti inokwezva)→kucherechedza→chengetedza

Iyo yakavezwa zvinhu zvekunakidza seapplus Billet yakapihwa muchoto kupfura, tembiricha ingangoita zviuru gumi nembiri degree Scelsius. Iyo mafuta ndeye hydrogen kana acetylene. Kudzora tembiricha muvira inyaya yakakosha. Pashure pokunge tube yabuda muvira, inofanira kuboora kuburikidza nekumanikidza kwekumanikidza.

Kazhinji, iyo yakajairika piercer ndiyo cone vhiri piercer. Rudzi urwu rwe piercer rune zvakanyanya kugadzirwa, yakanaka chigadzirwa mhando, yakakura fungidziro yedhisheni yekuwedzera, uye inogona kupfeka mhando dzakasiyana dzemhando dzesimbi. Mushure mekubaya, iyo Round tube billet inotevedzana kuteerana kune matatu kutenderera kwekuyambuka kutenderera, kuenderera mberi kuyerera kana kubuda. Mushure mekunze, iyo tube inofanira kubviswa kuti iite sizing. Saizingi neakakwira-kumhanya rotary cone kuchera maburi mu billet kuti aumbe tube. Iyo yemukati dhayamita yemuzambiringa yeiyo inotarisirwa nehurefu hwekunze kwekunze kwekudhirowa kweiyo dhizaini yemushini. Mushure mekunge pombi yesimbi yakura, inopinda shongwe yekutonhora uye inotonhorera nemvura inotsemuka. Pashure pokunge pombi yesimbi yapetwa, icharwirwa.

Mushure mekunje, pombi yesimbi inotumirwa kune iyo simbi yekudzvanya (kana hydraulic test) neiyo bhanhire remukati rekutsvaga kwemukati. Kana paine marara, mabhuru uye mamwe matambudziko mukati megomba reSimbi, ivo vanozoonekwa. Mushure mekuongororwa kwemhando yemhando yesimbi pombi, yakasarudzika bhuku rekusarudza rinodiwa. Mushure mekuongororwa kwemhando yemhando yeiyo pombi, penda iyo serial nhamba, kutaurwa, kugadzirwa batch nhamba, nezvimwewo nependi. Uye kusungirirwa muchitoro chechitoro ne crane ..
