Mapaipi makuru-dhayamita makobvu esimbi asina musono anogadzirwa kubva kusimbi ingot kana simbi yakasimba yeraundi inoboborwa mucapillary chubhu yozokungurutswa inopisa. Mapaipi makuru-dhayamita gobvu-akavakirwa simbi isina musono anoita basa rakakosha muindasitiri yepombi dzesimbi yenyika yangu. Zvinoenderana nehuwandu husina kukwana, kune vanopfuura 240 vagadziri vepombi vasina musono munyika yangu uye anopfuura 250 hombe-dhayamita gobvu-yakavezwa seamless simbi pombi mayuniti. Mapaipi makuru-dhayamita gobvu-akakomberedzwa seamless simbi mapaipi anonyanya kubva padhayamita rekunze repombi yesimbi. Kazhinji, avo vane dhayamita rekunze rinopfuura 325 mm vanodaidzwa kuti hombe-diameter simbi mapaipi. Kana ari madziro akakora, kazhinji, ayo ane madziro emadziro anodarika 20 mm anokwana. Izvi zvinotevera kugadzirwa kwepombi dzesimbi: Iyo mbishi yepombi dzesimbi isimbi pombi ma blanks. Pipe blanks inoda kuchekwa nemuchina wekucheka kuita isina chinhu nehurefu hunosvika 1 mita.

Uye kutumirwa kuchoto chekudziya kuburikidza nebhandi rekutakura. Iyo billet inoiswa muchoto uye inopisa kusvika kune tembiricha inosvika 1200 ° C. Iyo mafuta ndeye hydrogen kana acetylene. Kudzora tembiricha muchoto inyaya yakakosha. Mushure mekunge chubhu yakatenderedza yabuda muchoto, inofanirwa kubaiwa nemushini wekudzvanya. Kazhinji, mushini wekuboora wakajairika ndiwo mushini wekuboora tapered roller. Rudzi urwu rwemuchina wekuboora une hunyanzvi hwekugadzira, kunaka kwechigadzirwa, yakakura perforation dhayamita yekuwedzera, uye inogona kupinda mukati memhando dzakasiyana dzesimbi. Mushure mekuputika, iyo yakatenderera chubhu isina chinhu inotenderedzwa-yakatenderedzwa, ichipetwa ichienderera, kana extruded nematatu rollers. Mushure me extrusion, pombi inofanira kubviswa uye kuenzaniswa. Muchina wekuisa saizi unotenderedza chibooreso chetapered nekumhanya kukuru kupinda musimbi isina kubvongodza maburi kuita pombi yesimbi. Iyo dhayamita yemukati yepombi yesimbi inotarirwa nekunze kwedhayamita kureba kwechibhorani chemuchina wekuyera. Mushure mekunge pombi yesimbi yakakura, inopinda mushongwe yekutonhora uye inotonhorera nekupfapfaidza mvura. Mushure mokunge pombi yesimbi yatonhodzwa, ichagadziriswa (chaizvoizvo, vazhinji vanogadzira havachashandisi michina yekururamisa, asi varuramisa zvakananga pombi yesimbi mushure mokunge yapfuura nepakati peguyo. Yasvika pakururama kwepombi yayo yesimbi pachayo). Mushure mekutwasanuka, pombi yesimbi inotumirwa kune simbi isina kukwana detector (kana kuti hydraulic test) nebhandi rekutakura kuti uone kukanganisa kwemukati. Kana pane kuputika, mabhubhu, uye mamwe matambudziko mukati mepombi yesimbi, ivo vanozoonekwa. Mushure mekuongororwa kwemhando, pombi dzesimbi dzinofanirwa kuomesesa kusarudzwa kwemanyorerwo (ikozvino ese ane laser yekuona yekuongorora).
