Kuboora ndiyo nhanho yekutanga yekupisa-yakakungurutswamusono simbi pombideformation, uye basa rayo ndere kune yakasimba hollow tube billet yakapfeka se capillary.Nekuda kwekupfeka capillary surface defects kana eccentric (kusaenzana ukobvu) kwakaoma kubvisa kana kuderedza deformation maitiro, saka, kunaka kwe perforated capillary kune zvakakosha zvakanyanya pamhando yekupisa-yakakungurutswa seamless simbi pombi.Way pressure chubhu perforation punching, kusunda kuboora kutenderera nekuboora.Simbi yakakobvu-yakavezwa isina musono inonyanya kushandiswa mupetroleum geology yekuchera pombi, petrochemical inoshandiswa mukupwanya machubhu, boiler machubhu, pombi nemabhengi emotokari, matirakita, ndege uye humwe humbowo hwechubhu, maitiro ayo ekugadzira: inopisa yakakungurutswa isina seamless simbi chubhu kutenderera.→kudziyisa→matatu perforated roll rolling, rolling kana extrusion→detached→saizi (kana kuderedza) kutonhora→kutwasanudza→hydrostatic test (kana yekuyedza) logo→storage.

Inopisa-yakakungurutswa isina musono simbi ingot casting inogona kuparadza matishu, zviyo kunatsiridza simbi uye kubvisa hurema microstructure, kuitira kuti simbi dense tishu mechanical zvimiro zvivandudzwe.Kuvandudzwa uku kunonyanya kuratidzwa mugwara pamwe rolling nhungamiro kune imwe nhanho musimbi haisisiri isotropic;kudira akaumbwa mabubbles, makatsemuka uye vakasununguka, anogona welded panguva yakakwirira tembiricha uye kumanikidzwa.

Mushure inopisa-yakakungurutswa seamless simbi chubhu yakabikwa kuti ipfuure nekumanikidza puncher kubaya.Kazhinji zvakajairika punch ndeye tapered roller punching muchina, muchina wekubaya wakanyanya kugadzirwa kwakanaka, mhando yechigadzirwa, perforated kuwedzera huwandu, inogona kupfekwa simbi dzakasiyana.Mushure mekuputika, chubhu yakatenderedzwa yave matatu-roll rolling, rolling kana extrusion.Kusvina pombi mushure mekuita saizi.Sizing mill kuita high-speed cone drill through perforated steel embryo yakagadzirwa simbi.Pipe mukati dhayamita inotarwa nekunze dhayamita sizing chigayo chibooresa kureba.Mushure mekuyera pombi mushongwe yekutonhodza kuburikidza nekupfapfaidza inotonhorera pombi mushure mekutonhodza, inofanirwa kutwasanudzwa.Mushure mekutwasanura simbi inotakura bhandi kune simbi yekuona muchina (kana kudzvanywa bvunzo) yekuedzwa kwemukati.Kana iyo yemukati pombi inotsemuka, mabhuru uye dzimwe nyaya, ichaonekwa.Mushure mekusarudzwa kwesimbi asiwo kuburikidza neyakaomesesa yemhando control manual.Mushure memhando yesimbi, pfapfaidza pendi pane nhamba, saizi, nhamba yebatch uye zvichingodaro.Nekireni mudura.
